Even more news from Nurburgring: BMW, at their "M Night" celebration, debuted their new lightweight BMW M3 CRT sedan. Basically an upgraded and lighter GTS, the M3 CRT (Carbon Racing Technologies) uses the same carbon-intensive process that the BMW i3 and i8 models (coming in 2013) will use. The M3 CRT uses two carbon-fiber sheets on the hood, which encompass an aramid composite honeycomb giving it extra strength at a quarter of the weight.
Further weight-saving elements include a lightweight frame as well as lightweight front bucket seats. The interior comes equipped with a dual-clutch transmission, the BMW Individual audio system, parking sensors and standard built-in navigation. Total weight comes in at 3,483lbs, saving about 150lbs from the standard M3 sedan. Under the hood, the M3 CRT also differs from the standard M3 upgrading from the 4.0-liter V8 with 414hp to the GTS's 4.4-liter with 450hp and 324 lb-ft of torque. The M3 CRT has an aluminum-silicon alloy crankcase and a sport exhaust system with a lightweight titanium muffler.
In keeping with the 'upgraded-GTS' theme, the M3 CRT keeps the same 19-inch (lightweight version) wheels operating with the GTS six-piston front brakes with lightweight calipers and stainless steel brake lines. The M3 CRT is limited to only 67 units. Sadly, none will be made available for the US. Enjoy the video.
