2005 BMW 530xi Touring

The BMW E60 automobile platform is the basis of the 2004-onwards 5-Series automobile. It replaced the BMW E39 in 2004. Before the recent restyling, the models available were the 520i, 520d, 525i, 525d, 530i, 530d, 535d, 545i, and the M5. All models received an engine upgrade for 2006:

-The 523i replaced the 520i. The engine was the same as the old 525i detuned to 177bhp

-The 525i became available with the new 218bhp unit (up from 192 bhp).

-The 530i with 258bhp (up from 231bhp)

-The 530d became availabel withe 231bhp (up from 218bhp).

-New engine: the 540i with 302bhp.

-The 550i replaced the 545i in the fall of 2005.

-The 520d, 525d, the 535d and the M5 remained the same.

The E60 is available in both saloon and touring (E61) platforms. The exterior design by Chris Bangle and Adrian van Hooydonk is controversial, especially the "Bangle-butt" rear. Its iDrive system has been simplified compared with that in the 7 series. It can be ordered with options such as active cruise control, head-up display, active steering, and for audiophiles - the Harman Kardon Logic7 stereo system.

The BMW M5 is the high performance version of the range, and is one of the best performance saloon cars on the market, it balances superb handling (like all BMW 'M' cars) with huge power, delivered by a naturally aspirated 5.0 L (40-valve) V10 - that produces 373 kW (507 bhp (/PS)). The car has impressive performance, with a 0-62 time of 4.7 seconds, 0-124 time of 15 seconds, and a top speed in excess of 205 mph (when the electronic limiter of 155mph is removed). Few sedans can compare with the M5, and realistically only the new Mercedes-Benz - E63 AMG and Audi RS6 provide competition.

2005 BMW 630i

In 1989 the 6 Series was supplanted by the 8 Series, but in late 2003, the 6 Series was reintroduced as a 2004 model, with coupe and convertible versions based on the BMW E63 and BMW E64 platforms, respectively. These two models are each available with either a 3.0 L (2996 cc) straight-6 making 190 kW (258 hp DIN) at 6600 RPM and 300 Nm (221.3 ft.lbf) of torque from 2500–4000 RPM (in the 630i) or a 4.4 L (4398 cc) V8 making 245 kW (333 hp DIN) and 450 Nm (331.9 ft.lbf) of torque at 3600 RPM (in the 645Ci). In some markets, the convertible versions are sold as the 630i Cabriolet and the 645Ci Cabriolet.

The V8 in the 645Ci is the N62 engine, the same powerplant used in the 545i and 745i, with BMW's Valvetronic variable valve timing system. This is an all aluminum engine with 4 valves per cylinder. This 6-Series comes with either a 6 speed automatic transmission or a 6 speed SMG sequential gear box. For the 2006 model year, BMW renamed the 645Ci as the 650i. The reason for this change was the increase in engine displacement.

Unlike that of the new 5 Series and 7 Series models, the styling of the new 6 Series has generally received a warm welcome from the BMW community—except, largely, owners and enthusiasts of the E24. The new 6 Series was designed to look like a shark, and really does remind you of one. The controversial "Bangle-butt" rear styling works somewhat better on the shapely E63 than on other BMWs.

In 2005, an M6 version of the new 6 Series was introduced. It shares the E60 BMW M5's engine and transmission (507 bhp)

2005 BMW H2R

Sleek and aerodynamic, the BMW H2R ("Hydrogen Record Car") is one of the first of a new breed of racecars specially adapted to run on liquid hydrogen fuel. Conceived and developed in just 10 months, it has already set nine international speed records at the Miramas Proving Grounds in France.

The H2R’s 6.0-liter V-12 engine, which draws on BMW's advanced Valvetronic and Double-VANOS technology, is based on the 760i’s gasoline-fueled powerplant. This H2-powered high performer generates 232 horsepower, helping it to achieve a top speed of over 187 mph.

2005 BMW M5

This finest BMW 5-Series vehicle is the most powerful of all time: five liters of cubic capacity, ten cylinders, a maximum output of 507 bhp (DIN), a peak torque of 384 lb-ft and engine speeds redlining at 8,000 rpm, these are figures that speak for themselves. In an unprecedented way, these figures blur the lines between a car for everyday use and a vehicle for ambitious motor sport racing.

A successful recipe for two decades: power without overstatement.

With its performance figures, the fourth-generation BMW M5 once again sets the benchmark in the segment of powerful sports sedans, a niche which the first BMW M5 carved for itself back in 1984. During the last 20 years, this first BMW M5 and all its successors have made their mark, always setting the standard as a perfect symbiosis of a comfortable, elegant sedan for everyday use, abundant output delivered by a powerful engine and ultimate sportiness. With sales figures of approximately 35,000, the BMW M5 has proved to be an economically successful concept which combines prodigious performance with understatement, a basic feature of all M automobiles.

This principle reaches its culmination in the new BMW M5: this "extreme athlete" with its subtle appearance and the seemingly endless power of its ten-cylinder high-revving engine, which interacts perfectly with the seven-speed SMG gearbox, introduces the driver to completely new dimensions of effortlessness. To put it in a nutshell: in its class, which it shares with top-class competitors, the BMW M5 excels due to the most innovative drive concept, the best power-to-weight ratio, supreme handling and excellent everyday driving qualities. It is a fully roadworthy sedan with the heart of an athlete, a sports car which is perfectly suited for everyday motoring. The new M5 skilfully combines these two virtues.

First high-revving V10 engine to be featured in a regular-production sedan.

The V10 is the only high-revving power unit to be featured in a series-production car. Featured in the most powerful production car within the BMW model family, this new engine once again sets the benchmark in its class.

There is, however, more to it than pure performance. What is important for M automobiles is acceleration and driving dynamics, the latter which is dependent on the actual forward thrust and the vehicle's weight. The drive forces at the driven wheels are significantly influenced by the engine torque and the total ratio. The high-revving concept caters for an optimum transmission and rear-axle ratio, thus guaranteeing an impressive forward thrust.

The perfect choice: high-revving concept.

For the BMW M engineers the compact, high-revving normally aspirated engine was the ideal choice. With a red line of 8,250 rpm, the ten-cylinder engine has ventured into terrain which has so far been reserved for red-blooded racing cars. Compared to the previous BMW M5 eight-cylinder engine, performance has increased by more than 25 percent. The BMW M5 has also surpassed the magical 100 bhp per liter limit, its specific output being on par with that of racing cars.

A masterpiece in engine construction.

The two five-cylinder banks of the V10 are arranged at an angle of 90° to achieve a mass balance of the crankshaft drive, which is optimized for low vibration and increased comfort. For reasons of stiffness and due to the high loads resulting from combustion pressure, engine speed and vibrations, a bedplate design has been chosen for the crankcase, the first-ever application in a production V engine by BMW. For an optimum alignment of the crankshaft, grey-cast iron inserts have been integrated into the aluminum bedplate, which also serve to enhance acoustics, increase vibrational comfort and ensure a high oil supply rate. The extremely stiff crankshaft is supported by six bearings.

High-pressure bi-VANOS and individual throttle butterflies.

The bi-VANOS variable valve timing featured in the new BMW M5 engine ensures an optimum charge cycle, thus helping to achieve extremely short adjustment times. This means in practice: increased performance, an improved torque curve, optimum responsiveness, lower consumption and fewer emissions. Each cylinder has its own throttle, a feature typical of racing cars. Throttle control is fully electronic and cylinder bank specific.

Dual exhaust system made of stainless steel.

The exhaust system is made of seamless stainless steel and has a dual-flow design all the way to the silencers. The exhaust gases finally leave the system through four tailpipes which are what make the rear end of the M vehicles so unmistakable. The exhaust system complies with the European EU4 and the US LEV2 emission standards.

The engine control module: the first of its kind in the world.

The MS S65 engine management system is the central factor behind the V10's outstanding performance and emission data. This engine management system is unparalleled in its package density. Its processors are the most powerful ones which are currently approved for use in automobiles, as high engine speeds and comprehensive management and control tasks demand the utmost from this system.

Highlight in engine management: ionic current technology.

The ionic current technology featured by the engine management unit is a technological highlight which serves to detect engine knock, misfiring and combustion misses. Utilizing the spark plug in each cylinder, this system helps to pinpoint engine knock, to check for correct ignition and to detect any ignition misses. Thus, the spark plug has a dual function - as an actuator for the ignition and as a sensor for monitoring the combustion process.

Seven-speed SMG gearbox conveys M power to the tarmac.

The high-revving concept only succeeds in combination with a gearbox which translates the torque available to the engine, by means of a short overall transmission ratio, into optimized forward thrust.

The new seven-speed SMG gearbox is well suited to the V10 engine's power. BMW M is the first manufacturer worldwide to offer a seven-speed sequential gearbox with drivelogic function. The seven-speed SMG gearbox enables manual gear selection with ultra-short shifting times as well as comfortable cruising thanks to automated gear selection. The purpose of the additional seventh gear is to reduce engine speed and torque gaps.

New SMG gearbox's speed up by 20 percent.

With the seven-speed SMG gearbox, gears can be changed using the gearshift lever on the center console or the paddles on the steering wheel. Compared to the previous SMG transmission, changing gears is 20 percent faster with the new generation. Never before has it been quicker to change gears with a transmission of this kind. The advantage for the BMW M5 driver: Gear change is smooth and accomplished at a speed impossible to reach even by the most proficient driver, thus making the inevitable power flow interruptions when changing gears hardly noticeable.

Drivelogic: the driver determines the SMG's characteristics for changing gears.

Thanks to the SMG's drivelogic function, the driver can choose from eleven gear change options, which enable him to adapt the SMG's characteristics to his very own style of motoring.

Six of these programs can be pre-selected in the sequential manual gearbox mode (S mode), the spectrum ranging from balanced dynamic to very sporty. With the gearbox in the S mode, the driver always shifts gears manually. Whenever the driver activates the Launch Control function, the SMG Drivelogic shifts gears shortly before the maximum engine speed is reached at precisely the right moment and with optimum slip until the BMW M5 reaches its top speed.

In the Drive (D mode) automatic gearshift mode, the transmission shifts the seven gears automatically, depending on the program selected, the driving situation, the road speed and the position of the accelerator pedal.

SMG for increased safety and comfort.

The seven-speed SMG gearbox not only supports the driver in achieving motor sports performance, but also offers scores of safety features. In critical situations, when the driver shifts down on a slippery surface, for example, the gearbox opens the clutch in the fraction of a second in order to prevent the BMW M5 from swerving out of control in the event of excessive drag torque at the driven wheels. Further functions are the climbing, which prevents the car from rolling backwards during hill starts as well as the hill detection, which adjusts the shift points on gradients and descents. This prevents gear hunting when going uphill. When driving downhill, the hill detection holds the lower gears for longer in order to make effective use of the engine's braking power.

Maximum driving pleasure.

The interaction of the V10 engine and the seven-speed SMG gearbox results in a level of performance, which has so far been inconceivable for series-production sedans. Above all, there is one thing the BMW M5 gives to its driver: driving pleasure at its best. Compared to the previous BMW M5, the current model comes up trumps in all performance and fun disciplines: it accomplishes the 0 to 62 mph sprint in 4.7 seconds and reaches the 200 km/h (124 mph) mark after a mere 15 seconds to go on to the electronically limited top speed of 250 km/h (155 mph). A glance at the speedometer reveals where this power package would head for if maximum speed was not electronically limited: an awe-inspiring 330 km/h (205 mph).

The Nürburgring serves as a test track.

Compared to all direct competitors, the interaction of actual forward thrust and a low vehicle weight is a strong argument in favour of the new M5. Also in this respect, the BMW M5 sets the benchmark and leaves its competitors far behind.

An undisputed gauge of driving dynamics is the northern loop of the legendary Nürburgring race track. For decades, the world's most demanding race track has been the perfect place of separating the wheat from the chaff. There is no other place where the interaction of vehicle components when taken to the limits can be observed as well as on the Nürburgring's northern loop. With lap times of approximately eight minutes, the BMW M5 can hold its own and is a worthy competitor of thoroughbred sports cars, leaving its competitors far behind. By the way: traditionally, all M vehicles are tested there.

M suspension based on the 5-Series: the icing on the cake.

The aforementioned lap time demonstrates that the BMW M5 can be extremely sporty. Although the suspension of the basic 5-Series model is undoubtedly very good, such a record performance with respect to dynamics would not be possible. This is why the BMW M5 is also totally unique with regard to its suspension.

Many detail solutions and changes turn the 5-Series into an BMW M5.

Consequently, the suspension and its electronic assistants have been either exclusively developed for the new BMW M5, undergone extensive modifications or adapted to the special M performance. For example, the BMW M5's running gear is by no means a lowered 5-Series suspension. Instead, it is an optimized design created from scratch. The suspension assisting systems, some of which have the same name as those of the 5-Series, have been optimized for this vehicle. On the one hand, this suspension contributes greatly to the BMW M5 being the technological culmination of the successful BMW 5-Series. On the other hand, it clearly demonstrates that the BMW M5 is a unique model with a distinctive appearance.

Variable M differential lock.

The BMW M5 has a variable, torque-sensing differential lock bestowing the vehicle with a high level of driving stability and optimum traction, above all when accelerating out of bends. Even in extremely demanding driving situations, i.e. when there are major differences in the coefficients of friction at the driven wheels, it offers a decisive advantage in terms of traction. A further advantage is that it instantly builds up an increasing locking power if the speed difference between the driven wheels rises, thus guaranteeing optimum forward progress at all times.

Only featured in the BMW M5: DSC with two selectable driving dynamics programs.

A new generation of the Dynamic Stability Control (DSC) has been especially developed for the BMW M5. The DSC system can be deactivated by pressing a button on the selector lever cover. The driving dynamics programs are pre-selected in the so-called MDrive and can be called up using the MDrive button on the steering wheel. While the first DSC mode by and large corresponds to that of the 5-Series, the second mode - the M Dynamic Mode - is highly appreciated by sports-minded drivers.

EDC: the spectrum ranges from sportingly firm to comfortable.

The BMW M5's Electronic Damper Control (EDC) enables the driver to choose from three programs (comfort, normal and sport), thereby adjusting the suspension characteristics accordingly. The driver can operate the EDC function via the MDrive button on the steering wheel or the push button next to the SMG selector lever.

High-performance brakes derived from motor sport.

To complement its immense power output, the BMW M5 is equipped with a generously sized high-performance braking system with perforated, weight-optimized compound brake discs. The aluminum twin-piston sliding calipers (analogous to the BMW 7 Series), which have been optimized for minimum weight and maximum stiffness, help the BMW M5 to achieve stopping distances similar to those of red-blooded sports cars: deceleration from 62 mph to 0 is accomplished in under 36 meters, the braking distance from 124 mph to a standstill is less than 140 meters.

The high-performance business express.

A wolf in sheep's clothing - this description would fit if the basic 5-Series, and particularly the new M5, looked "tame" when viewed from outside. In fact, the 5-Series already looks sporty, elegant and athletic. It is no coincidence that this 5-Series represents BMW's dynamic business class. The BMW M5 is set apart from the basic model by a host of striking and hidden details, which further add to its powerful, sporty and dynamic looks. An athlete in business attire would be an apt description of the new BMW M5.

Exterior with understatement.

The differences in design versus the basic 5-Series are discreet but consistent, giving the BMW M5 a surprisingly high level of uniqueness in terms of looks, without questioning the common genes with the BMW model series. The modified front and rear aprons are instant eye catchers. Another difference is the modified side sills and the more prominent wheel arches. Traditionally, the M differs from the "normal" BMW in its exclusive exterior mirror design, the four tailpipes, which have also become an unmistakable feature of all M vehicles, and the exclusive wheel design. For the first time, the BMW M5 sports very attractive gills which are incorporated into the front side panel.

An even sportier interior.

The BMW M5 comes with a leather interior in three different colors, which makes it look even more sophisticated than the lavishly equipped basic model or - for an extra price - with a full leather interior, which looks absolutely stunning. Further important differences versus the 5-Series are the instrument cluster, the optional M-specific head-up display, the steering wheel with MDrive buttons and the redesigned center console.

Business express for everyday use.

All vehicles made by BMW M GmbH are very convenient for everyday motoring. This particularly applies to the BMW M5: despite its awe-inspiring performance which is reminiscent of that of a racing car, it has remained an elegant and comfortable sedan perfectly suitable for longer journeys, an integral characteristic of BMW 5-Series cars. Thus, one can say that the BMW M5's racing ambitions neither impair driving comfort, active and passive safety, nor do they reduce the space available for passengers and luggage. Even in terms of consumption and environmental compatibility, the BMW M5 is a real paragon - just like all BMW automobiles.

2005 BMW M6

With the launch of the BMW M6, BMW M GmbH is proud to present the most dynamic and sporting rendition of the BMW 6-Series Coupe. This makes BMW's large Coupe, in the guise of the BMW M6, one of the most beautiful cars in the world - and at the same time, the most sophisticated and powerful 6-Series ever: five- liter engine capacity, 10 cylinders, 507 horsepower, 383 lb-ft maximum torque, and engine speed beyond the 8,000 rpm limit.

Together with the outstanding, uncompromising suspension designed and built exclusively for sporting performance, this extraordinary power unit gives the BMW M6 all the qualities of a thoroughbred super sports car. But unlike its competitors, the BMW M6 comes with all the space and comfort of a typical 2+2-seater, plus the luxurious features of a typical luxury performance BMW.

The success principle: True power in a discreet package.

The BMW M6 shares its unique power unit with the BMW M5. Ever since being introduced in the M5, this engine has been acknowledged as the benchmark, just as the M5 is the very epitome of the Sports Saloon.

Now, based on its outstanding performance, the BMW M6 sets a new standard in the segment of high-performance 2+2-seater luxury sports cars. Creating this unique model, the engineers at BMW M GmbH have focused not only on the sheer power of the engine, but also on the weight of the body and, as a result, the mass to be accelerated as quickly as possible on the road. Reducing weight to a sensible minimum, the BMW M6 comes with all the driving dynamics required for the race track, while in terms of motoring comfort and equipment it is simply ideal for all roads the world over. Not least, the body design of the BMW M6 modified only discreetly versus the elegant look of the BMW Coupe comes with all the understatement so characteristic of all M Models as their elementary feature.

Interacting with the seven-speed SMG transmission, the magnificent chassis and suspension, the elegant body in innovative lightweight technology, as well as the wide range of luxury equipment, the ten-cylinder high-speed engine gives the customer a brand-new dimension in motoring performance.

It is difficult to find any genuine competitors to the BMW M6, since all other more or less comparable cars are either all-out supersports or sports sedans far inferior in terms of agility. So given the car's innovative drive concept, a power-to-weight ratio even better than on the M5, as well as unique handling - and all this with all the everyday driving qualities of a large coupe - the engineers at BMW M GmbH rightly claim that the new BMW M6 truly comes in a class of its own.

V10 power unit running at racing speeds.

Sharing BMW's V10 power unit, the BMW M5 and BMW M6 come with one of the rare high-speed engines in regular sedan and coupe production. Within the entire BMW family, the V10 is indeed the most demanding engine in technical terms and, without doubt, the top performer in every respect.

Power and performance, however, are not everything. Rather, what really counts is a car's acceleration and driving dynamics on the road. And this depends, first, on the weight of a car and, second, on the thrust and power which actually goes to the drive wheels - which, in turn, are a result of engine torque and the overall transmission ratio. BMW's high-speed engine concept allows an optimum gearbox and final drive transmission ratio in all cases, thus guaranteeing impressive thrust and momentum on the road at all times.

The perfect choice: High-revving concept.

A compact, high-revving normal-aspiration engine is the best of all strategies in generating maximum engine output: Revving up to speed of 8,250 rpm, the V10 reaches a speed range reserved until recently to purebred racing cars alone. As a result, the engine exceeds the magical limit of 100 hp per liter, again achieving specific output of a standard otherwise only found in motorsport.

The two five-cylinder banks in the V10 are arranged at an angle of 90° in order to optimize the standard of vibration control and motoring comfort offered by full mass compensation on the crankdrive. Taking the substantial forces of the combustion process, high engine speeds and vibrations into account, the crankcase comes in bedplate design. The extremely stiff crankshaft, in turn, runs in six bearings.

Variable dual-VANOS camshaft control ensures an optimum cylinder charge cycle in the interest of extremely fast valve timing. On the road this means even more performance, an improved torque curve, optimum responsiveness, lower fuel consumption, and emissions reduced to a minimum. Again reflecting the typical features of motorsport, each cylinder comes with its own throttle butterfly masterminded fully electronically for each row of cylinders.

Twin-chamber exhaust system made of stainless steel.

Made of stainless steel without any connecting seams, the exhaust system comes in twin-chamber configuration all the way to the silencers, before exhaust emissions leave the car through the four tailpipes so characteristic of every BMW M Car. It almost goes without saying that exhaust emissions meet the European EU4 and, respectively, the US LEV2 standards. The BMW M6 stands out from the M5 also through its even more powerful and sporting sound.

This outstanding performance and emission management is ensured and masterminded by the central engine management unit featuring the most powerful processors currently to be found in any car anywhere, since the demands made of the management system are obviously particularly stringent due to the very high engine speed and the sum total of all control and management functions.

A particular highlight of the engine control unit is ionic current technology serving to detect any tendency of the engine to knock, misfire and suffer mis-combustion. This intelligent control unit is able to sense any tendency to knock via the spark plug in each cylinder, checking the correct ignition setting and recognizing any tendency to misfire and thus allowing the engine to run as closely as possible to its theoretical limits, developing optimum power and performance in the process. The spark plug serves both as an actuator for the ignition and as a sensor observing the combustion process.

Seven-speed SMG transmission conveying M Power to the road.

BMW's seven-speed SMG transmission will be the only one offered in the new BMW M6. This gearbox from BMW M is indeed the world's only sequential transmission with seven gears and Drivelogic. With qualities even greater than on a six-speed SMG gearbox, this transmission allows manual selection of gears with extremely short gearshift times as well as comfortable cruising qualities thanks to the automatic gear selection function. And at the same time the additional gear keeps the increments between engine speed and torque even smaller, ensuring an absolutely smooth process of one gear "flowing" into the other.

The driver shifts gears in the SMG transmission either from the selector lever or via paddles in the steering wheel. Compared with the conventional SMG transmission, the new generation of SMG technology performs the entire gearshift process 20 per cent faster, gears merging directly into one another.

As a result, any interruption of the flow of power inevitable when shifting gears now becomes hardly perceptible. The BMW M6 accelerates virtually without the slightest jolt or interruption from a standstill all the way to top speed.

Drivelogic: The driver determines how SMG shifts gears.

Featuring its special Drivelogic function, SMG on the BMW M6 offers the driver a total of 11 gearshift options allowing him to individually adjust the gearshift characteristics of the SMG transmission to his personal style of motoring.

Six of these driving programs come in the sequential manual function (S-mode), ranging from smooth but dynamic all the way to race track crisp. Driving in the S-mode, the driver shifts gears manually. But thanks to the launch control function SMG Drivelogic shifts gears automatically shortly before the engine reaches its maximum speed, ensuring an optimum gearshift process with optimum spin control all the way to the top speed of the BMW M6.

In the automatic shift mode (Drive = D-mode), the transmission shifts the seven gears automatically as a function of the driving program currently in use, the driving situation, road speed, and the position of the gas pedal.

SMG for even greater safety and motoring comfort.

Seven-speed SMG supports the driver not only in achieving and enjoying the highest standard of performance comparable to genuine motorsport. It also comes with many safety features opening up the clutch within fractions of a second in a critical situation - for example when shifting down on a slippery surface - in order to keep the car stable and free of excessive engine forces acting on the drive wheels. A further special function is hill detection, which adjusts the gearshift points on uphill and downhill grades. Driving uphill, this avoids the common phenomenon of the gears constantly shifting up and down ("pendulum gearshift"); driving downhill the hill detection mode holds lower gears in mesh longer than usual in order to capitalize on the engine's braking effect.

Last but not least, SMG also enhances the particular sound effect of the V10 power unit: To quote a specialist commenting on this special sound, that "brief, roaring rumble" is simply fantastic when the electronic engine control unit "blips" the throttle between gears when shifting down.

Maximum driving pleasure.

Interaction of the V10 power unit and seven-speed SMG gives the driver of the BMW M6 Coupe driving pleasure of the highest caliber: Acceleration from 0-100 km/h (62 mph) comes in 4.6 seconds and the BMW M6 reaches 200 km/h or 124 mph in just about 14 seconds. Then, at a speed of 250 km/h or 155 mph, the electronic speed governor ends the car's irresistible surge of power, while the speedometer gives you an idea where the engine would take you without such electronic speed control: the speedometer goes all the way to 330 km/h or 205 mph.

Lapping the Northern Circuit of Nürburgring in 8 minutes.

The world-famous Nordschleife, the Northern Circuit of the legendary Nürburgring Race Track, is the perfect benchmark for measuring driving dynamics. For it is here, on the world's most demanding race track, that the exceptional stand out from the mediocre in terms of driving dynamics. Nowhere else is the interaction of all a car's components as clear as here, when driving to the absolute limit. Lapping the Northern Circuit in around 8 minutes, the BMW M6 easily matches the most thoroughbred sports cars, clearly beating the competition.

M Suspension: The icing on the cake of the BMW 6-Series.

Lap times of this kind clearly bear testimony to the BMW M6's driving qualities. Which is actually no surprise, considering that the chassis and suspension already outstanding on the BMW 6-Series as such. The modern assistance systems have been specially adapted on the BMW M6 for truly unparalleled M Performance. Compared with the M5, in turn, the wheelbase is shorter and the car comes with a lower centre of gravity for extra agility on the road. In terms of both chassis equipment and set-up, the BMW M6 is therefore a unique car in every respect.

Variable M Differential Lock.

The variable, speed-sensing M Differential Lock gives the BMW M6 superior driving stability and optimum traction particularly when accelerating out of a bend. Even in very demanding driving situations, the differential offers crucial advantages in terms of traction, for example with the drive wheels running on very different surfaces with a wide range of different frictional coefficients.

A further advantage - the locking action immediately builds up when necessary to compensate for any difference in speed between the drive wheels, thus ensuring smooth and powerful drive forces at all times.

DSC with two dynamic driving programs available on demand.

The BMW M6 boasts a brand-new generation of Dynamic Stability Control. With the first stage of DSC being conceived for maximum driving safety, the M Dynamic mode, as on the M5, is tailored to the sporting driver. And pressing a button on the selector lever cover, the driver is able to switch off DSC whenever he wishes.

EDC: From firm and taut all the way to comfortable and extra-smooth.

EDC Electronic Damper Control on the BMW M6 offers the driver the choice of three programs available on demand: Comfort, Normal, and Sports, with the car's chassis and suspension ranging from sporting and taut all the way to - relatively - smooth and comfortable. The driver operates EDC via the MDrive button on the steering wheel or the push button next to the SMG selector lever.

High-performance brakes like in motorsport.

Reflecting its truly outstanding power and performance, the BMW M6 naturally features extra-large high-performance brakes complete with cross-drilled extra-low-weight compound brake discs. The double-piston swing calipers are made of aluminum and are optimized for both weight and stiffness. Applying the brakes from a speed of 100 km/h (62 mph), the driver of the BMW M6 comes to a standstill after just 36 meters and takes less than 140 meters to reach a stop from a speed of 200 km/h (124 mph).

High-performance athlete in a beautiful body.

With the BMW 6-Series already acknowledged as a strikingly beautiful car, the BMW M6 enhances this impression to an even higher standard. Special design features making this unique Coupe look even more powerful and dynamic, while remaining discreet and unpretentious.

The most eye-catching feature is the truly impressive front air dam. And like all design features on a BMW M Car, this particular element focuses once again primarily on its specific function: The V10 power unit requires roughly twice as much cooling air as the V8 in the BMW 645Ci. Large secondary intake openings to the left and right of the front air dam thus give the engine of the BMW M6 even more air to breathe and cool the brakes at the same time. Through their design alone, finally, these air openings accentuate the sporting character of the car.

Lightweight engineering and beautiful design in perfect harmony.

Beneath the doors the side-sills powerfully contoured for aerodynamic reasons again emphasize the dynamic impression of this sports coupe. At the same time the side-sills stretch the car for an even sleeker look, making the BMW M6 even lower and more dynamic in its appearance.

The 19-inch forged aluminum wheels developed especially for the BMW M6, together with their five filigree double spokes, are extremely light and provide a very good view of the large brake discs. Compared with comparable wheels, the weight saving is 1.8 kilos per wheel.

The M model logo in the ornamental slats at the side tells the connoisseur right away that this car is one of the outstanding athletes within the BMW M Family. And like on all M Models, the exterior mirrors come in their very own, sporting look.

The rear air dam with its characteristic diffuser opening again serves first and foremost to provide an aerodynamic function. But at the same time it adds an even more sporting look to the car. The particular design of the diffuser improves the flow of air along the underside and reduces lift forces. The four tailpipes on the twin-chamber exhaust system, bordering the diffuser opening in pairs on either side, are one of the signs of distinction so typical of a BMW M Car.

First-ever carbon-fiber roof in series production.

The first car to feature a roof made of carbon-fiber was the BMW M3 CSL. Now, following that special model built in small, strictly limited series, BMW M GmbH is introducing a carbon-fiber roof on the BMW M6 Coupe, thus raising this concept of intelligent lightweight technology to a new dimension in series production.

Offering the same stability and crash safety as a steel roof, this carbon-fiber material derived from motorsport is significantly lighter than aluminum, let alone steel. The result is a significant reduction in weight and mass lowering the car's center of gravity.

Inside, the BMW M6 stands out from the "basic" model also through its even more sophisticated Merino leather upholstery with a choice of three different colors or - at extra cost - with full leather upholstery leaving absolutely nothing to be desired.

A sports car for everyday motoring.

Despite its simply staggering performance, the BMW M6 does not make any compromises in terms of adequate roominess as well as active and passive safety of the highest standard. Even the level of motoring comfort is virtually the same as in the "regular" model. And when it comes to both fuel economy and environmental compatibility, the BMW M6 again lives up the exemplary standard of all BMWs.

2005 BMW X3

The BMW X3 is a compact luxury crossover SUV produced by the German automaker BMW. It is based on the BMW 3-Series automobile platform. The X3 3.0i won the Canadian Car of the Year Best New Sport Utility Vehicle award for 2005.

History and development

Along the heels of a very successful and ongoing production run of the BMW X5, BMW decided in the early millennium that it wanted to compete with the likes of the Freelander, Lexus RX and other small luxury SUV's just as the X5 had previously done so well in its respective classes. Thus the X3 (internally known as E83), was born.

What thus emerged was a concept unveiled at the Detroit Auto Show in 2003. Dubbed the xActivity, BMW previewed to the public for the first time what a smaller SAV based on a 3 series platform would look like. The concept had no windows, for the most part no roof, and a sleek futuristic interior. Only the basic shape of the car would emerge as the BMW X3.

Just as BMW used many parts from the E39 5 Series parts bin in the making of the X5, the same occurred in the X3's development, whereby BMW engineers reused 3 series parts. In-fact complete sets of parts came straight out of the E46 330xi, emerging unscathed in the X3 (e.g. rear suspension).

Austrian automotive contractor Magna Steyr of Graz, Austria performed additional development work and has been contracted to manufacture all first-generation X3's.

xDrive

When the BMW X3 premiered in late 2003, BMW announced that it would be using a new 4 wheel drive system to power it and its bigger brother - The (refreshed) X5.

Instead of a 60-40 (rear-front) power split (which all millennium 4 wheel drive BMW's exhibit - 325xi, 330xi, early X5) with power being cut to wheels which lost traction through DSC (Dynamic Stability Control), xDrive allowed both of these vehicles to split power between the front and rear axles through use of a multiplate clutch located between the gearbox and the Cardan shaft. This setup allowed xDrive vehicles to split power in virtually any way it pleased. If the car felt like it was in a threatening situation (note not an unstable one), xDrive would react immediately, often before the driver ever knew of its intervention, to alleviate traction and control of the vehicle. xDrive is also closely knit with DSC. In the case that wheelspin stills occurs while xDrive is or has been shifting power, DSC can brake independent wheels to regain traction. xDrive also helps in cornering. When the vehicle feels it is about to understeer or oversteer, the vehicle cuts traction to either of the front wheels or rear wheels to help regain stability and keep the driver on the road.

The two key things about xDrive are, first, it being one one of the first technologies used to intervene before the driver was ever aware that the car could be unstable, and second, it being transparent (i.e. unknown) to the driver.

Reaction

Right from the start, the BMW X3 had been criticized for its harsh ride and poor interior by critics. BMW rectified both in 2005, with a slightly softer ride and by matching plastics and carpeting in the 2005 X5's. It has also been criticized for not being built at a BMW factory. However, Magna Steyer, the factory in Austria has won numerous awards for quality and is the highest rated car assembly factory in Europe.

The automotive press however for the most part had mixed views of the X3 ranging all over the spectrum - unusual for BMW, but then again not so unsual for modern BMW's.

2005 BMW X5

The history of the X5 begins in the late 1990s, when Chris Bangle drew the first sketches from his Designworks studio in California. In many ways, the current car closely resembles these initial sketches.

The takeover of Rover proved to be very beneficial for BMW in the development of the X5. BMW engineers were able to look and use Range Rover technology and parts in the development of the X5-one such example would be hill descent control. In many respects the X5 was also influenced designwise by its British counterpart; in this case the X5 got the two-piece tailgate straight from the Range Rover. Many parts and electronics were also taken directly from the E39 5 series parts bin to save costs.

In contrast to the Range Rover models, however, the X5 was designed as a sporting car. BMW reportedly worked hard to ensure it was referred to as an SAV (Sports Activity Vehicle) instead of an SUV (Sports Utility Vehicle).

Even though the X5 was a four wheel drive vehicle, BMW chose from the start to route 60% of the engine's torque to the rear wheels, making it feel as close as possible to the company's rear-wheel drive sedans. Many reviewers commented on its road and track "feeling", and as time passed many other manufactures have caught onto this breed of SUV (e.g. Porsche Cayenne).

The X5 has been criticized for having low interior volume for its size - both the smaller BMW X3 and the 5 Series (Touring) have greater interior volume. The next generation X5 is rumored to rectify this problem.

The X5, along with the BMW Z4 roadster, are currently manufactured exclusively in BMW's South Carolina plant in Spartanburg, South Carolina.

2004 refresh

For 2004 the X5 was refreshed with new headlights, a few new exterior colors, a new four-wheel drive system and upgraded engines. The exterior touches kept it fresh and gave the X5 a more aggressive look. The grilles were enlarged, as well as their actual slats being modified in a 'flame surfaced' style. In keeping with the E39 refresh of 2001, the 2004 X5's headlights got "angel-eyes" (rings or halos around all front headlamps). The taillights also got an E39-style refresh treatment and the exterior glass went from a "dotted" pattern to a cleaner one of "lines". BMW invented a new four-wheel drive system dubbed xDrive shared both in the X5 and X3 in 2004. Instead of using the previous X5 system which consisted of power being split 60-40 (rear wheels-front wheels) and DSC to brake wheels losing traction, xDrive could variably cut off power to the front or rear axles in a matter of milliseconds, while transferring 100% of the engine power to either, thus allowing the vehicle to regain traction quickly.

In terms of engines, the X5 got the new 4.4i engine which debuted in the 2002 7-Series. This raised output from 290 to 325 hp (242 kW). Also from April production, a new X5 4.8is was offered (see below), giving the driver 265 kW (355 hp) and making it the 2nd fastest SUV behind the Porsche Cayenne Turbo.

Several new extras were added to the 2004 X5 such as:
+ Soft-boot close feature (the top part of the trunk pulls itself closed)
+ Trailer Stabilization Control
+ Adaptive Headlights (available only with xenon HID headlamps; these swivel with the direction of travel of the car)

Originally announced in the end of 2003 along with the rest of the X5 refresh, the X5 4.8is first started shipping in April 2004. In had a new larger 4.8 L engine (which replaced the 4.6 L engine), and was also later used in the 2005 750i/Li. It also included a slightly modified bodykit (parts of the bottom bumper became painted the body color), 20" wheels, and along with the 4.6is, were the only X5's ever to have a large chrome-tipped exhaust which hid the quad pipes.

2005 BMW Z4 Coupe Concept

The long and sleek engine compartment lid, the passenger compartment moved far to the rear, and the short overhangs front and rear impressively visualise all those classical attributes so typical of BMW: Within the engine bay lurks a longitudinally mounted straight-six conveying its power to the rear axle in the interest of supreme driving dynamics. In conjunction with the car's long wheelbase and the centre of gravity visibly moved far to the rear, the Coupé right from the start creates the impression of a top-flight athlete urging forward with all his energy.

The Concept Car is powered by BMW's new 3.0-litre straight-six developing maximum output of 195 kW/265 hp and peak torque of 315 Nm/232 lb-ft. Acceleration from 0-100 km/h is expected to take only about 5.7 seconds, with the car's top speed ending at the 250 km/h (155 mph) mark applicable to BMW's production models.

Equipped with the most advanced and sophisticated suspension control systems, Electrical Power Steering (EPS), as well as a high-performance brake system, the Z4 Coupé Concept Car is able to use all its power safely and reliably. The extremely stiff bodyshell, in turn, ensures driving dynamics of the highest standard, together with a level of above-average crash safety quite unusual in a sports car.

Contrasts, not Comprises: Dynamic also in Design.

With its uncompromising technical features focusing on top-level performance, the Z4 Coupé clearly offers driving dynamics of the highest standard. And the car's designers have been just as uncompromising in giving the car an unparalleled look of dynamic performance right from the start. Contrasts in the car's design ensure an acute sense of supreme tension - and tension also creates and bears out dynamism in design.

The fascinating aesthetic look of the Z4 Coupé Concept Car is based on the highly expressive design language of the BMW Z4 Roadster. Indeed, the interplay of concave and convex surfaces merging in powerful and striking lines gives the body of the car not only unique character, but also a touch of clearly perceptible dynamism even at a standstill. The flowing roofline, in turn, characterises the BMW Z4 Coupé as a classic coupé with its centre of gravity moved at least visibly to the rear axle.

The recess in the middle of the roof, in turn, reinforces the sporting look and character of this classic coupé, the combination of these elements giving the car a touch of forward-oriented dynamism from every angle: The BMW Z4 Coupé is low, fast and, at the same time, elegant in its looks.

The glazed part of the passenger cell referred to by experts as the "greenhouse" visibly tapers out into the rear end, accentuating the rear wheel arches in a powerful and muscular look. The spoiler designed into the rear lid, in turn, ensures optimum aerodynamics and streamlining, with the third brake light integrated beneath the spoiler in the rear lid. A further effect of the spoiler and brake light is the additional emphasis they give to the sheer width of the car's rear end.

The seam around the rear lid extends discreetly along the rear side windows, finally merging into the sill line of the car. As a result, the Z4 Coupé Concept Car retains the sporting look of its rear side windows with that characteristic Hofmeister "kick" also with the rear lid open. And beneath the rear lid, finally, the Z4 offers luggage capacity quite remarkable for a sports car of any calibre.

Exterior paintwork in Glacier Silver developed exclusively for the Concept Car gives this unique Coupé the silky-matt glossiness of a sculpture made of massive aluminium. Nineteen-inch aluminium wheels clearly revealing their three dimensions and finished intentionally in a dark colour contrasting with the paint of the car underline the highly focused and powerful expression conveyed by the Z4 Coupé. Made exclusively for this Concept Car, the wheels are a product of the most elaborate casting technology.

Dynamism for Your Senses: the Interior.

Giving great attention - and, indeed, love - to detail, BMW's colour and trim designers have created a unique interior tailored in every respect to the BMW Z4 Coupé Concept. The most modern materials in first-class quality are combined with one another exclusively for this Concept Car, offering features and highlights never seen before. Hence, the sophisticated interior points far into the future of interior design with all its potentials.

Like the exterior, the interior of the Z4 Coupé Concept uses contrasts instead of compromises to generate the sensation of dynamism and excitement.
The use and combination of materials and colours harmonises the technical and sporting features of the exterior with soft and harmonious elements within the interior, thus creating a world of peacefulness and tranquillity.

Matt and glossy surfaces form intentional contrasts intermingling with the numerous solid aluminium units inside the car, extending the technical features and fortes of the Z4 Coupé visibly far into the interior. And at the same time soft, top-quality leather in warm brown colours exudes the feeling of being cocooned within this Ultimate Driving Machine. "Cold" high technology and "warm" cosiness - in this case this is not a contradiction in terms, but rather a harmonious blend of supreme qualities.

Light and Dark Surfaces Interacting with One Another.

Black and coloured surfaces clearly distinguish the various function levels from one another, the driver perceiving the black surfaces along the car's upper sill line as a clear delineation from the exterior at the same time creating a feeling of pleasant safety.

The contrasts and brightness of the interior convey a clear signal of open-mindedness and grandeur. An expression of space further enhanced by the arrangement of colours on the dashboard and the interior trim.

High-Gloss and Woven Leather as Clear Signs of Tradition and Progress.
Silky high-gloss leather and classic, timeless woven leather form an intentional contrast to the almost silky Nubuk leather inside the car.
The aluminium pedals and the footwells come complete with inserts made of robust burr leather. And we find the same combinations of top-quality materials within the luggage compartment and in the travel baggage integrated therein.

Aluminium - an Experience in Looks and Touch.

Over and above sumptuous leather, the interior is characterised throughout by polished and brushed aluminium components in the trim around the door closing handle, with the rotary knob for the air conditioning, the pedals and the loading sill on the luggage compartment all milled out of one single block of aluminium. So that these massive aluminium components are a genuine experience not only in their looks, but also in their touch.

A Concept Car with a Good Potential for Entering the Market.

Designed consistently for the sporting and ambitious driver and conceived for active motoring, the BMW Z4 Coupé Concept Study gives its occupants a direct feeling for the road combined with pure driving pleasure. At the same time the most advanced technologies on the drivetrain, suspension and safety system meet all the demands of even the most discerning coupé customer. And last but certainly not least, the Z4 Coupé Concept offers adequate space and all the motoring comfort and convenience even the enthusiastic aficionado of a thoroughbred sports car would not like to miss these days in a sporting two-seater of this calibre.

2006 BMW 320d

The E90 automobile platform is the fifth and latest generation of BMW's 3 Series entry-level luxury car / compact executive car. It replaced the E46 sedan and touring models in 2005. The E90's dimensions are larger than its predecessor's in every aspect, and for the first time since the E21, the volume model 320i uses an Inline-4 engine. However, despite the change for the sedan and touring models, the current 3 series coupé, M3, and cabriolet variants are still based upon the E46.

First offered to the market in March 2005, it had quickly become BMW Group's best selling automobile worldwide by the end of the year with 229,900 vehicles delivered.

E46 comparison

The E90 sedan is 49 mm longer than the E46 equivalent, 78 mm wider, 9 mm taller and the wheelbase has been increased by 35 mm. As a result, the current 3 Series is only slightly smaller than a 5 Series from the 1980s.

Despite the increased dimensions, the E90 is actually lighter than the E46, which can be attributed to a number of factors. Large amounts of aluminum were used to construct the front-end, evident on parts such as the axle being created entirely of the substance, and the engine which uses that and magnesium where possible rather than traditional materials. The current 320i is powered by further development of the old E46 318i (143 hp) engine. Comparing these two vehicles, the E90 is approximately 35 kg lighter (1435 vs. 1470). The differences are even greater when comparing the E90 325i (European version) and the E46 325i. The E90 is weighs 1505 kg and uses a 218 hp (160 kW) engine, while the E46 weighs 1570 kg and is propelled by 192 hp (141 kW). The new engine, however, needs to rev higher in order to achieve maximum output (6500 rpm instead of 6000).

Other novelties includes the six-speed manual transmission, intended to reduce fuel consumption, and the run-flat tires, which, according to BMW, allows the vehicle to maintain control and continue in case of punctuation (for a limited stretch with moderate speed). Consequently, the car is not equipped with a spare wheel.

Awards

In April 2006, the E90 received the World Car of the Year award 2006 from a jury of 46 international automotive journalists. The car was praised for its excellent balance between performance and practicality, as well as between style and seriousness. The jury were also impressed by the new diesel engines and the all wheel drive variants.
