M3 CRT is currently the fastest M car from Bmw

Article by Christian Andrei, on December 30, 2011

Autobild has created a special edition on BMW M models aptly named "Fascination M." Autobild made a comparison that provides an overview of all present BMW M models and the M GmbH. Autobild brought all the currently available M models and made them compete against each other on Sachsenring, a German race track.

The M3 CRT is the fastest M car Autobild that was ever tested on Sachsenring with a lap time of 1:38.87 minute. The M3 GTS isn't available anymore. The brand-new F10 M5 sedan took second place with a lap time of 1:38.90, just a 3 hundredth of a second slower than the M3 CRT.

Coming in at No. 3 is the 1M coupe, which is slightly faster than the M3 Coupe which was also slightly faster than the M3 sedan. It should be mentioned that the M3 convertible lost about 2 seconds to the coupe. The X6M and X5M ran equally fast too. But then, there’s no denying that both are faster than the old E60 M5.

Taking direct inspiration from the world of motorsport, the new BMW M3 CRT (Carbon Racing Technology) is an embodiment of a well-focused fusion of advanced development expertise, especially in the field of drive system intelligent lightweight design and chassis technology. Moreover, the new BMW M3 CRT marks the global debut of a new production process for carbon-fiber reinforced plastic (CFRP) components in the auto industry, allowing this materials to be used extensively in building high-performance BMW M3 Saloon-based sports car.

In addition, this new production process allowed BMW M to attain an excellent weight-to-power ratio of 3.5 kilograms per horsepower, with the high-revving V8 engine providing 331 kW (450 hp) in max output. These values allow the new BMW M3 CRT to sprint from nil to 100 km/h in just 4.4 seconds.

Just like the BMW M3 GTS of which a limited run of 135 examples were built by BMW M’s factory, only 67 units of the new BMW M3 CRT will be assembled. This makes the BMW M3 CRT the second small-series, high-performance M3 derivative ready to race on the track but could be driven on the road.

This high-performing nature of the BMW M3 CRT is highlighted by its bespoke lightweight design components, like its bonnet and the bucket seats for the driver and front passenger.

These components are made from a cellular carbon honeycomb that is manufactured using a new distinct process that was first employed for producing body components for the BMW i3 and BMW i8 models.

Both the BMW M3 GTS and the BMW M3 CRT will have a body which has a passenger cell area that is made from CFRP. The newly developed production process allows reprocessing of the residual cuttings during the construction of the body. This process now enables the basic material made from carbon fiber thread to be woven into CFRP mats of any size, before being imbued with synthetic resin and hardened just like the material employed in the body of both the BMW i3 and BMW i8.

In the case of the BMW M3 CRT, the new process permits BMW M to create a bonnet made from two CFRP moldings that encase an aramid honeycomb structure. This results to a CFRP bonnet that is as strong as its conventional steel counterpart, but weighs just a quarter of its weight. It is also 50-percent lighter than the aluminum bonnet of the standard BMW M3 Saloon.
