Contrary to the norm, the SRT version is the first model to hit the streets, instead of coming out six to 18 months after mainstream variants. Not more than 10,000 of these 2008-and-change versions will be built, and all will be powered by the familiar and bloody wonderful 6.1-liter Hemi. It's the same as in SRT versions of the Chrysler 300 and Dodge Charger, as is the five-speed automatic transmission, the only gearbox offered at launch. Dodge is mum about future model and powertrain offerings, but if you look at what else can be had in the sedans, it's not unreasonable to figure out. Expect a base version running the 250-horsepower, 3.5-liter V-6 and a midlevel (likely badged R/T) Challenger packing the 5.7-liter, 350-horse Hemi. One if not both of the V-8s will be offered with a manual transmission.
