Bmw announced the end of production for the fourth generation M3 Coupe. More than 40,000 examples left the factory since its introduction. However, if you still want an M3, Bmw will still continue production of the M3 Convertible until September 2013. Bmw sold almost 10,000 M3 Sedan models and around 16,000 M3 Convertibles.
Each model is powered by the 4.0-liter V8 engine, which develops a maximum output of 420 hp (309 kW) and a maximum torque of 400 Nm (295 lb-ft). This engine also won the 3.0 to 4.0-litre class of the International Engine of the Year Award five times in succession. Moreover, the M3 E92, also introduced the M3 DCT Drivelogic, the first double-clutch transmission for the series-produced vehicles.
Bmw says that the M3 was a trailblazer in its class when it came to intelligent lightweight construction as it featured an aluminum bonnet, plastic front side panels and a carbon fiber roof. For those who don’t know, the M3 was produced at the Bmw plant in Regensburg alongside with the 3-Series Sedan, Coupe and Convertible, while the V8 engine was supplied by the Bmw engine factory in Munich.
Bmw also produced some small-series variants of the M3, such as the M3 GTS, which was developed as a road-legal clubsport-oriented model, powered by a 4.4-liter V8 delivering 450 hp (331 kW).
Only 135 examples of the M3 GTS were delivered to customers.The Bavarian manufacturer also built the M3 CRT (Carbon Racing Technology) in 2011 in a limited run of 67 units.
The M3 CRT was powered by the same 4.4-liter V8 engine with 450 hp (331 kW). This model boasted exclusively manufactured lightweight components, as it featured an innovative carbon-fibre-reinforced plastic (CFRP) manufacturing process. Its bonnet was made from two CFRP mouldings encasing an aramid honeycomb structure, while the bucket seats were made from two CFRP layers wrapped around a recycled-paper honeycomb.
Powering the new BMW M3 CRT is new variant of the V8 engine -- developed exclusively for the BMW M3 – that boasts of higher displacement as well as higher levels of output and torque. BMW tuned this high-revving engine to deliver linear power and response expected from an M car, all honed on the race track.
As tuned, this 4,360-cc V8 engine on the BMW M3 GTS delivers 450 hp (331 kW) of max output at 8,300 rpm, as well as 440 Newton meters of peak torque available at 3,750 rpm. The dynamic power of this V8 engine is thanks to the fact that it features a number of elements derived directly from motor sport. These elements include a bedplate crankcase construction made from aluminum-silicon alloy, a knock control system with ion current technology, individual throttle butterflies as well as optimized wet sump oil supply.
Power is sent from the V9 engine to the rear wheels through the M double-clutch transmission, featuring Drivelogic developed for the BMW M3. This transmission unit operates employing principle developed in motorsport, paving way for uninterrupted flow of power even when changing gears, thereby resulting to a more dynamic acceleration. The shift attributes of this M double-clutch transmission with Drivelogic have been tuned to harmoniously match the V8 engine of the BMW M3 CRT.
Interestingly, the new BMW M3 CRT is provided with shift paddles on the steering wheel, thereby allowing the driver to shift gears manually without having to move their hands away from the wheel. The new BMW M3 CRT is also provided with a Launch Control function, allowing it to deliver optimal sprint from a standstill.
