Let's get right to it, shall we? The much-anticipated Challenger (available only in SRT8 strength to start) features a 6.1-liter HEMI V8 good for 425 horsepower and 420 pound-feet of torque. "Performance targets" include zero-to-60 mph sprints of the low five-second variety and quarter-mile times less than 14 seconds. The Challenger SRT8 will be available in orange, silver or black and offer niceties like a navigation system, Bluetooth phone connectivity and the comprehensive MyGIG infotainment system. Muscle madness starts Spring 2008 at a starting MSRP of $37,995. Less expensive, less powerful Challengers will follow.
