444 hp, no displcament change (111 hp/L sounds about right)
44 kg diet

... and R-tyres & M-DCT for sure

wow...i have seen some pics of that car....it looks ace.....i think it will have around 420bhp....

the new M3 has been out for a while and with 420hp but here we discuss the upcoming M3 CSL

Power is far from everything, last CSL told us that if we did not know already!

So what do we think about a "Club Sport package"? One more like that on the GT3 than the one presented on the E46. Is that possible?

Let's look at the previous M3 vs M3 CSL.

The E46 M3 was 343PS, 365Nm torque and 1570 weight. The E46 M3 CSL was 360PS, 370Nm torque and 1385kg...or 185 kg less...or about 12% less than the standard M3.

My prediction for the E91 M3 CSL is about 460hp with 450Nm of torque and about 1450-1500kgs. It will have the new DynamicPerformanceControl differential along with the new double-clutch gear box.

Are you sure? I found the following online...

Built for Top Performance: BMW M3 CSL Lightweight Concept Car.
This will really make the hearts of all sports car enthusiasts skip a beat. Presenting the M3 CSL, BMW is proudly hightlighting the concept of a lightweight sports car at the 2001 Frankfurt Motor Show - a truly unique driving machine resting on wide wheels and impressively proving the potential of intelligent weight reduction. This is clearly borne out by three figures describing the fortes of this prototype not only to the connoisseur: Weight reduction of about 200 kilograms, power-to-weight ratio under 3.5 kilos per horsepower, lap time on the northern circuit of Nurburgring less than eight minutes.

Formula 1 technology in lightweight and drivetrain engineering.
This phenomenal lap time is the result of a consistent concept based on "intelligent" lightweight engineering: The optimum combination of materials and components using the most suitable material for each component and its specific requirements. This strategy is directly connected to BMW's Formula 1 technology carried over to the road by the M3 CSL on a number of fundamental points. Just one example is the consistent use on the car of carbon-fiber reinforced plastic, the material in Formula 1 racing.

Looking at the engine, the high-speed concept of BMW M's well-known M3 straight-six again underlines the role of lightweight engineering in engine construction. Thoroughly modified, the upgraded engine comes with a streamlined cylinder charge process with more than 350bhp. And to shift gears within fraction of a second, ensuring a direct flow of power at all times, the car naturally features BMW's Sequential M Gearbox with Drivelogic (SMG), again based directly on Formula 1 technology. Featuring electrohydraulic, micorprocessor-controlled clutch operation, this highly advanced transmission is masterminded by two paddles directly on the steering wheel. Through its overall concept and harmony of features, this lightweight sports car is designed and built for dynamic motoring of the highest standard.

Lightweight engineering is nevertheless not a purpose in itself by the making of the M3 CSL of BMW M. Rather, the absolute weight and the mass inertia of a car around its vertical axis are crucial to the car's lateral, vertical and longitudinal dynamics - that is how the driver experiences the dynamic behavior of his car. Just for comparison, the series-production BMW M3 weighs 1,495 kg or 3,296 lb unladen, while the M3 CSL Concept Car is about 200 kilos (440lb) lighter. Precisely this is the crucial factor, the power-to-weight ratio being essential for optimum longitudinal dynamics, that is fast acceleration. And here the improvement is even more significant, the series-production M3 coming with a power-to-weight ratio of 4.36kg/bhp (9.6lb/bhp) versus less than 3.5kg/bhp (7.7 lb/bhp) of the M3 CSL Concept Car.
