M3 CSL Donates Equipment to Create New M3 Coupe Competition Package Option
[ Author: wm | Dodano: 09.10 2006r. ]

Already renowned for its performance and handling, the new Competition Package takes M3 performance to the razors edge. Every aspect of the M3 handling has been tweaked resulting in the best-handling M3 ever.

The wheels are 19-inch forged-alloy wheels with high-performance tires. They connect to a suspension that has been tuned specifically for the Competition Package. Turn-in is quicker with a more direct steering ratio which goes from 15.4:1 to 14.5:1.

The Dynamic Stability Control system includes a less intrusive M track mode, as on the M3 CSL, ensuring the security of DSC and spirited driving too. For inclement conditions the regular DSC mode remains. The brakes, also adopted from the M3 CSL, include compound and cross-drilled rotors. The front rotors have also been enlarged from 12.8 to 13.6 inches.

As the serious enthusiast would expect, the Competition Package is available in combination with the standard six-speed manual or the optional Sequential Manual Gearbox.

The interior enhancements of the package are subtle but purposeful. The Alcantara steering wheel and handbrake grip feel good to the touch. The addition of the steering wheel-mounted button for the DSC M track mode requires the deletion of the multi-function controls and cruise control. The Competition Package is available with all M3 Coupe interior and exterior color combinations. Two trim items are exclusive to the Competition Package. Special Competition Package aluminum trim is included on the interior. A new exterior color, Interlagos Blue, is offered only with this package.

The Competition Package will be available for 2005 M3 Coupes beginning with December 2004 production and it will make its debut at the Los Angeles Auto Show. The price for the package will be $4,000.

2006 BMW 6-Series Performance-Luxury Coupe and Convertible Now with More Power and New Refinements
[ Author: wm | Dodano: 09.09 2006r. ]

For 2006, the BMW 6 Series features a new, more powerful engine; new standard equipment and options; and significant technical and esthetic refinements.

For the new model year, the models are the newly powered and named BMW 650i Coupe; and the BMW 650i Convertible. Each is powered by a new 4.8-liter, 360-bhp Valvetronic V-8 that is also winning hearts and minds in the ‘06 750i/Li and 550i models.

The New 4.8-liter Valvetronic V-8 Engine

Under the new BMW 650i models’ aluminum hood is a further evolution of the technologically advanced and unique N62 V-8 engine that powered the former 645Ci models. As such, this power unit continues with BMW’s revolutionary Valvetronic system, which controls engine power by varying valve lift instead of relying on a conventional throttle. Compared to conventional valvegear, Valvetronic enhances torque, power and efficiency – and now increased displacement further boosts torque and power.

The BMW 6 Series‘ exhaust system is specially engineered to lend the V-8 engine an extra-sporty note. Actuated by engine vacuum in response to engine speed and load as well as the gear currently engaged, a movable element in the right-hand resonator is programmed to achieve the sportiest, most pleasurable engine sound within the overall legal exterior-noise limit.

Three Available Transmissions, All 6-Speeds

The standard transmission is the heavier-duty version of two new 6-speed manuals recently introduced. The first optional transmission is the 6-speed STEPTRONIC automatic. This combination of torque converter and 6-speed gearbox is plenty sporty – as demonstrated by a 0-60-mph time only a tenth of a second less quick than for the manual transmission or SMG. The Sequential Manual Gearbox (SMG) is the “third way” of driving. This is an electrohydraulically shifted and clutched, electronically controlled version of the 6-speed manual transmission; as such it is utterly different from a conventional automatic. There is no clutch pedal; the driver selects the desired mode (N, R, D, S) with a console-mounted selector lever, and can execute manual shifts via that lever or two “paddles” on the steering wheel.

The Look: Esthetics and Function

With this performance-luxury Coupe and Convertible pair, the Bavarian automaker shows in yet another way “what it can do” in terms of contemporary design. From the bold BMW “kidney” grilles and the freely shaped lighting clusters flanking them…through a very long hood signifying power…through a sleek and graceful silhouette…to BMW’s characteristic (and “highly” functional) rear deck: This is BMW in the 21st century.

The primary aerodynamic goal has been achieved, as demonstrated by an excellent coefficient of aerodynamic drag (CD) of 0.30 (Coupe) or 0.32 (Convertible) and a highway EPA mileage rating of 25 mpg with automatic transmission for both models.

Another goal, low aerodynamic lift, was met in a fascinating way. The main upper trunklid line begins in the C-pillar and defines its rear edge all the way around. Above this, across the lid’s center, there’s a rise – a spoiler lip, just a few millimeters tall. Wind-tunnel tests indicated the necessity for this; Boyer’s designers shaped it ideally. But it couldn’t be formed in steel or aluminum. The solution: make the trunklid out of Sheet Molding Compound, or SMC.

Inside: iDrive Control Center with Voice Command

The overall arrangement is as in the 5 and 7 Series, with a traditionally configured instrument cluster in front of the driver and the iDrive-dominated center dash area. Yet this design is different from either 5 or 7, in that the trim material (Pearl-gloss Ruthenium is standard) does not extend all the way across the dash; instead, it is concentrated in the center area, and repeats on the right side above the glove compartment. Graceful sweeps of certain surfaces – from dash top into door panel, from dash right-of-center into the console – lend elegance and visual interest.

A text-to-speech engine makes it possible to translate various text messages, such as radio-station names and (in the future) received e-mails, into voice form. In the interaction of graphics and speech, for example, one can dial the number of a programmed phone contact merely by speaking his or her name. The system can recognize 3000 words.

BMW Biturbo 3.0-liter Engine
[ Author: Webmaster | Dodano: 02/23/2006 ]

Backing up its global success with the innovative 507 bhp V10 powerplant for the M5 and M6 super cars (2005 Engine of the Year), and the VALVETRONIC magnesium-aluminum straight-six engines introduced in 2005, BMW is set to tear the wraps off a production-ready biturbo version of its acclaimed petrol-powered six-cylinder.

Retaining the familiar 3.0-litre capacity, the new all-aluminum engine boasts a pair of turbochargers, each feeding a trio of cylinders.

When combined with the efficiency and flexibility of acclaimed BMW VALVETRONIC and double-VANOS technology, the new engine is able to produce an immense 300 bhp of power and 295 lb-ft of torque.

It is armed with a Table Mountain-like torque profile that defies the term curve. Peak torque of 295 lb-ft is delivered between 1,500 rpm and 5,800 rpm and the engine boasts a 7,000 rpm red line.

The biturbo six-cylinder has the same power and more torque than the muscular 4.0-litre V8 engine fitted to the 740i.

The new engine further entrenches BMW as the manufacturer of the world’s most intelligent, advanced and dynamic engines for the enthusiast driver.

However, in keeping with BMW philosophy, the substantially enhanced performance does not come at a substantial cost to the environment. Fuel consumption, previously a bug-bear of high-performance turbo-charged engines, has been radically reduced thanks to high-precision direct petrol injection, used for the first time on a BMW six-cylinder motor. The V12 powered BMW 760i/Li features direct petrol injection for its 6.0-litre engine.

A further traditional turbo-engine wrinkle has been ironed out by BMW engineers: turbo lag. In the new engine, this has been completely removed, thanks to low inertia turbochargers.

The driver need only brush the accelerator pedal to receive an immediate surge of power and performance, as the engine delivers an electrifying response.

While turbocharger technology is almost as old as the internal combustion engine itself, in combination with cutting-edge high-precision direct petrol injection technology BMW engineers were able to write a new and exciting chapter in the history of forced-induction.

The foundation for all this power and torque is drawn from the exemplary characteristics of the magnesium-aluminum 3.0-litre engine which is rated at 262 bhp. This in itself is quite outstanding for a normally aspirated engine. Compared with the proven 3.0-litre normally aspirated magnesium-aluminum engine, the all-aluminum engine featuring new biturbo technology increases overall output by approximately 15 percent. Peak torque shoots up by an even more impressive 30 percent.

The resulting 300 bhp and 295 lb-ft of torque deliver outstanding thrust and driving power all the way across the rev range.

The only way to achieve such an increase in power and performance with a normally-aspirated engine would be to significantly increase engine size, which would also mean a corresponding increase in weight and the negative effects on the car’s overall balance.

The BMW combination of turbocharger technology with high-precision petrol injection is a particularly efficient way to meet even greater demands in terms of output and torque.

And for comparison, the new straight-six biturbo weighs about 155 lbs less than an approximately equally powerful eight-cylinder normally-aspirated engine displacing 4.0 liters. That is about the same weight as a moderately sized passenger.

Direct petrol injection also offers a significant fuel consumption saving of about 10 per cent compared with a similarly powerful turbocharged engine that uses regular fuel injection.

Turbines made of high heat-resistant special steel can withstand temperatures of up to 1,050 C and therefore do not need the cooling effect of extra air flow. Particularly under full load, this means a significant decrease in fuel consumption.

High-precision fuel injection allows an even more exact dosage of fuel as well as a higher compression ratio – ideal conditions for increasing engine efficiency and significantly reducing fuel consumption.

All this is made possible by the central position of the piezo-injector between the valves. Fitted in this position, the innovative injector opening to the outside is able to distribute fuel in a conical burst ensuring particularly smooth distribution of fuel within the combustion chamber.

Apart from its low weight and class-leading fuel economy, the new biturbo engine is able to offer yet another unique BMW feature. This is supreme smoothness and refinement, precisely the virtue which has made BMW straight-six power units the benchmark for refined drive technology, acknowledged the world over.

Indeed, the natural perfection of the straight-six layout gives the engine perfect balance in terms of free mass forces, avoiding vibrations even at high engine speeds.

A further important point is that this turbocharged version of BMW’s six-cylinder comes with the same hollow, extra-light camshafts as on the normally-aspirated engine, as well as an electrically driven coolant pump operating only as required.

Developing this new straight-six with biturbo technology, BMW is opening up a new chapter in the long history of the turbocharged engine, which dates back to 1905 and the work of Swiss engineer Alfred Bchi. Initially turbo-charged engines were restricted to marine and aircraft engines. It was only much later that the technology migrated to cars. BMW began its association with turbocharged road cars with the now famous 1973 BMW 2002 Turbo road car.

BMW will announce at a later date which of its vehicles will receive this new engine.

BMW M Coupe to Enter Series Production
[ Author: Webmaster | Dodano: 11/23/2005 ]

Following strong consumer reaction to the concept Z4 Coupe at the 2005 Frankfurt and Tokyo Auto Shows, BMW has confirmed that both the Z4 Coupe and an M version, the M Coupe will enter series production.

Visitors in Frankfurt and Tokyo were captivated by the car’s stylish body with its unique silken matte finish, tailored in the very best style of a classic sports coupe. While the driving dynamics potential of the vehicle was clear in its strong, purposeful lines, equally appealing to visitors was the striking interior design.

To be produced in Spartanburg, S.C., the first vehicles will be delivered to customers as early as June 2006.

The proven 255 horsepower (U.S. SAE net) in-line 6-cylinder engine with its high output and lightweight magnesium and aluminum construction promises superior agility and high performance. It not only catapults the Z4 Coupe to the top of the international competitive field but is also demonstrates the enormous performance capacity of the fundamental BMW Z4 Roadster concept – which forms the basis of the coupe.

BMW is also working to produce a high-end variation as quickly as possible and the result will be the return of the M Coupe, based on the new Z4 Coupe. Powered by the exciting 3.2-liter high-rpm engine, familiar from the BMW M3 and winner of many international awards, it will also come out in June 2006.
