said it before and i will again, but 700hp is 100bhp/L plus another 130 for the supercharger - that's proper amounts of power. it's what we've come to expect from high-performance german engines, not big supercharged american V8s. kudos to SMS

SMS, is one of the finest quality firms(used to be Saleen), its just a great package. I love the looks of the Challenger, there's nothing like a Supercharged American V8.
Bear in mind, i still love the SL55 AMG.
