As with all new innovative production sports cars, seems the horsepower must go up year after year to show either progress or dominance. Heres Spy pic's of the new ZL1 Z06 coming out. It'll be the top of the line of 3 Z06's to be produced. From Corvette article
" When Chevrolet rolls out the 6th gen Corvette at the North American Inter. Auto Show in January, the Gen 4 V8 will have a reported 405 hp, the same as the current Z06. Insiders at both GM and suppliers say the Z06 will have an even 500hp, but will not be the most powerful Corvette. That prize will belong to the limited production ZL1 which is producing 625 hp in production trim. The Gen4 has thinner bore walls, stronger bulkheads, and retains the cast-in-place iron cylinder liners. The casting process includes a mechanically induced rapid chilling of the bulkheads to promote swift directional solidification of the aluminum and a fine grain structure , both of which improve dimensional stability. A composite barrel crank core replaces the current segmented barrel design, again for tighter and more consistant bore dimensions. The cores are screwed and glued together, the aluminum is pumped in rather than poured, and all the oil galleries are drilled and machined."
A subsequent note next to a pic of a C6( the old pic of the white car with the masks on it) states that the ZL1 is a twin turbo model."
Remeber NASCAR cars are 700HP, now think of the time when Avg. cars running around have 550rwhp. Things will be moving then,, lol.
