In 2004 Chrysler found a winning formula in the Crossfire Coupe, with its low-slung bumper and rear-wheel drive. The Roadster followed in 2005. Judging by the 2008 models, which are a carryover from 2007, it appears Chrysler has yet to strike a similar dollar-earning formula. However, in terms of policy there has been a major change: the SRT 6, with its 330-horsepower, smoke-spitting, supercharged V-6 engine has been discontinued.
