Why wouldn't the EPA allow 500-600 hp? They ALLOWED 550 hp for the Ford GT. I think we will see 500 plus hp in a limited edition Challenger in 2009 or 2010. These are some awesome times as far as the horsepower wars go. Buy now. They won't last long. Some granola munchin' liberal will find some reason to limit a car to 150 hp just like the junk we were offered from 75-85. Remember those boring automotive years? My mother had a 1981 Dodge Omni. I think it had 85 hp. Wow, what a rocket! 0-60 in 35 seconds!
