Bmw M3 Showcar ‘Chrome Bullet’ is one shiny sports car

Article by Christian Andrei, on October 10, 2011

Although there are plenty of custom M3 vehicles, Bmw decided that it’s time make something different and unveiled the M3 Showcar ‘Chrome Bullet’. The car is currently found at the Bmw Museum and it is waiting for visitors or a possible Arab customer. Under the hood, the M3 Chrome Bullet carries the same 4.0 litre V8 engine capable to deliver 309 kW/420 bhp and a maximum torque of 295 lb·ft (400 N·m) at 3900 rpm.

With these numbers the car can sprint from 0 to 100 km/h (62 mph) in 4.8 seconds when using a manual 6-speed manual transmission and in just 4.6 seconds when using the 7-speed M dual clutch transmission.

As you can see from the photos, the car is also fitted with the Competition Package, which offers a lowered suspension (10 mm), a new set of 19-inch Y-spoke wheels as well as a rear spoiler and front apron flaps in carbon. Still, we don’t believe that we will see this car on the streets due to its “shiny” look and we believe that the best place to see it is in a museum!

The V8 engine that powers the BMW M3 Coupe has its power channeled to the wheels in the rear using the manual 6-speed close-ratio gearbox. Utilizing an internal ventilation ensures the twin-disc clutch’s heat dissipation was optimized while the oil cooling management that is dependent on temperature has been integrated to the transmission. This is because the performance requirements of the M3 Coupe meant that heat management would play an important role from clutch and transmission. Aside from the manual 6-speed transmission, BMW will be offering for the M3 Coupe the highly distinct double-clutch 7-speed gearbox.

Designed specifically for engines with high rpm, this M double-clutch has a Drivelogic and is able to change gears with interrupting the flow of power even for a little. Called as M DCT Drivelogic for short, it drags out the best performance there is from the M3 Coupe but also ensures that the shift from a gear to the next is smooth.

In fact, changing gears under the M DCT Drivelogic is the same as that of the Sequential M Gearbox. What this meant was that even if one was to manually shift the gears, there would not be any need for its clutch paddle. Thus, the driver will no longer need to remove the foot from its gas pedal when undergoing a change in shift. In particular, the Drivelogic control gives drivers the choice of 11 different shift programs, 6 under manual and 5 under automatic, to meet their personal preferences. For manual operation, it can be activated using the sports shift lever, a feature that is exclusively fitted in the M3 Coupe. It is also possible to do this through the steering wheel’s paddles by pulling the left paddle if one wants to shift down while pulling the right-hand means a shift up.

Under the M3 Coupe, its final drive with have the Variable M Differential Lock which can deliver, when necessary, a maximum 100% locking action that has a fully variable action. This guarantees that traction is optimized for any road surface. Since there is a need to respond to the discrepancy on the right wheel in the rear with the left one in terms of speed, this feature gives the best support as it improves not only the positive qualities of a rear-wheel drive but even its qualities.
