I just spoke to M.Benz engineer and found out; all 2003 M.Benz AMG 55 models will have V8 supercharged engine which will produce 471 HP !!!! Starting with CL55, S55 2003 models and SL55 Later this year New E- Class will be introduced and the 2004 E55 model will also have 471HP V8 supercharged. No wonder the ///M5 will have V10. BMW has to compete the power game. I guess 400+ HP will be mendatory in order to be even called as a sports car in 2003..whoo.a...
