MB debut a prototype G55 at California Speedway today, alongside a SL55. It was black on black with special AMG wheels and chromed side exhaust tips. The spec. says 0 - 60 in 7.8 sec.

I could be wrong but I did a quick check on MB website and it says "0 - 60 is 10sec. estimated" for a '02 G500. The '03 G55 motor is the normal aspirated 349hp./374lb-ft. 5.5l V8. I wish they put in the new supercharged 470hp 5.5l V8
