Challenger – the name couldn’t be any more appropriate. Modern American muscle has been the sole realm of the Ford Mustang for years. That ends with the launch of the 2008 Dodge Challenger SRT8, a 425-horsepower pavement-peeling retro ride that’s got enthusiasts salivating and Ford’s pony surely riled. Yeah, it’s got a Hemi, one with 6.1 liters of displacement and pushing 425 horses at 6,200 rpm and 420 lb.-ft. of torque at 4,800 rpm. A five-speed automatic transmission with a manual mode directs the engine’s grunt to the rear set of 20-inch Goodyears.
