Back in July we got our first taste of the 2011 Dodge Challenger's spec sheet, confirming the 6.4-liter HEMI for the SRT8 and putting pricing in the $25,000-$43,000 range. Today, what looks to be an internal dealer document has surfaced, revealing more details--including specific horsepower figures.

The numbers aren't a surprise: the 6.4-Liter HEMI is rated at 475 horsepower and 460 pound-feet of twist according to the leaked info. Those figures are a touch on the low side of what was expected, but still enough to give Dodge the idea that the new Challenger SRT8 will offer some competition for the 2011 Ford Shelby GT500.

Having driven the 2011 Shelby GT500 on track at VIR, however, Dodge will have to do some serious work on weight and suspension to keep pace with the nimbler, more powerful Mustang.

The 5.7-liter HEMI under the hood of the R/T turns out 379 horsepower and 410 pound-feet of torque, a mild upgrade from the 372 horsepower and 400 pound-feet of the current 2010 Challenger, but again lagging behind the 2011 Mustang GT and Camaro SS.

In the base V-6 car, output jumps more noticeably from 250 horsepower to 305 horsepower, right on par with the new generation V-6s from Ford and Chevy. Torque is up as well, from 250 to 268 pound-feet. The engine also grows 0.1 liters to 3.6 liters in displacement, indicating it's a massaged version of the new Pentastar V-6.
