Thanks much for the info this is a big deal is the getrag an option ?




The second Challenger we drove was almost identical to the first, except that it was equipped with a prototype Getrag torque-sensing limited-slip differential. Boy, what a difference this simple part makes on a damp racetrack. Stability control was less eager to step in, and the chassis hooked up in places where the other car struggled for traction - there's something fundamentally wrong with a 425-hp, rear-wheel-drive car that relies on ESP and ABS to control wheel spin. The good news is that SRT tells us that this differential, conveniently, works with stock ESP programming. Look for it as an option, most likely paired with a six-speed manual gearbox, on 2009 Challengers. In addition, the 2009 lineup will grow to include a V-6-powered Challenger and a V-8 R/T model with about 350 hp.
