When the BMW E46 M3 CSL was unleashed last decade, the model's entire focus was cutting fat- offering a spectacular stripped-down combination of low curb weights and high performance abilities. With only 1,000 produced, it became an instant hit, and created an alliance of enthusiasts that favored acceleration over luxury. These people were hoping for a CSL comeback on the new M3 and M4, unveiled at the Detroit Auto Show.

However, BMW recently told Top Gear that this model isn't in the making. They claim we shouldn't be greedy, and that the new models are already as light as they can be. One of the weight reductions in the new model comes from the move from a 4.0-liter V8 to a twin-turbo 3.0-liter straight-six. While this change has also unsettled many M devotees, the new engine is good for 431 horsepower and 406 lb-ft of torque, producing promised 0-62 mph times of 4.1 seconds. As the fastest production cars currently manufactured by BMW, this should keep CSL campaigners complacent, at least for now.
