The inline-six is a reliable choice.
Many enthusiasts consider the M3 CSL E46 to be one of the best performance cars ever produced by BMW. Bavarian firm says that the light weight construction of the M3 CSL was not an advertisement promise. It is deeply rooted within the DNA of the unique sports car. The curb weight is just 3,053 lb (1,385 kg), making it 242 lb (110 kg) lighter that a standard M3 Coupe of the same generation. However, this is not all.
This M3 has a proven S54B32HP inline six engine. It is basically the performance version the highly capable S54B32. This engine produces 17 horsepower more than the standard model. What is the power of an M3 CSL?
A dyno is the only way to find out. A new video by Evolve Automobile shows a black M3 CSL hitting the dyno to check its power. The same channel also recently filmed a rare Z3 M on the Dyno, with the two vehicles sharing an identical engine. However, the Z3 M uses the non-performance version 3.2-liter mill.
Let’s now get to the numbers. The stock M3 CSL produces 360.7 horsepower (254.3kW) at the flywheel and 269.5 lbft (3565.4 Nm) at the crank. These numbers are close to the BMW listed for the car. The host of the video explains that the torque curve appears very healthy, with a peak at the end.
The M3 Coupe Sport Leichtbau offers more than just an extra powerful engine. The M3 Coupe Sport Leichtbau has many other modifications that make it a powerful track machine. It is very popular on the second-hand marketplace, with only 1,383 units being produced.
