Sorry if I cannot express myself correctly, but I don't know English as good as I want, so my answers will probably be the same in many cases.

Porsche has just released pictures and statistics on it's 2009 GT challenger, the RSR. (What is the second R for? I think RS = Renn Sport.) Power is down from last year's 465 hp @ 8,000 rpm to 450 hp @ 7,800 rpm, but displacement is increased from 3.8 - 4.0L. Torque stays the same at 317 lb-ft at 7,250 rpm. Weight is 1,220 for ACO, 1,245 kg for FIA. Price is €380,000.
As you can see in the pics below, the front fascia has some more fancy bits on the front and a louvred hood for the A/C.
More info.
I suppose this thread could be moved to the hide out if a mod wants it there - or even General Automotive. I put it here as it is a race car though.
