We’ve already had a quick look at the minor exterior updates applied to the 2011 Dodge Challenger, but thanks to some leaked documentation, we now have a general rundown of what to expect under the hood, as well.
As predicted, V-6 Challengers abandon the sluggish 250-horsepower, 3.5-liter V-6 in favor of Chrysler’s new 3.6-liter Pentastar V-6. Although the new 3.6-liter is typically rated at 285 horsepower in other applications, its output has been bumped up for use within the Challenger. If the secret dealer documentation holds true, expect the Challenger-spec V-6 to pump out roughly 305 horsepower and 268 pound-feet of torque. That’s certainly a healthy upgrade for the Challenger, and it also places the V-6 car in (roughly) the same neighborhood as the six-cylinder forms of both the 2011 Ford Mustang (305 horsepower) and Chevrolet Camaro (304 or 312 horsepower, depending on who you believe).
R/T cars continue to use the 5.7-liter V-8 — and yes, in the power-focused world of the Challenger, the engine is still referred to as a Hemi. There may, however, be an extra perk for opting to pair the V-8 with the optional six-speed manual transmission. According to the documentation, stick-shift R/Ts reportedly throw down 379 horsepower and 410 pound-feet of torque, roughly seven ponies and ten pound-feet more than their siblings fitted with slushboxes.
2011 Challenger SRT8 models seem to abide by the “there’s no replacement for displacement” mantra. As such, the 6.1-liter V-8 will give way for a slightly larger 6.4-liter V-8, although you may never hear Dodge refer to the engine as such. Instead, expect all labeling, emblems, and marketing to allude to a 392 Hemi, allowing Dodge to invoke the cubic-inch-centric nomenclature of its past muscle cars.
Regardless of its name, expect the 6.4/ 392 to be one powerful engine. The dealer overview says the engine is rated at 475 horsepower and 460 pound-feet of torque, roughly 50 horsepower and 40 pound-feet more than the 6.1-liter V-8 found in 2010 Challenger SRT8 models. Speculation suggests that figure may well be underrated, but seeing as Chrysler’s refraining from commenting on the entire matter for the time being, we’ll have to wait, strap a 2011 SRT8 to a dyno, and see for ourselves.
If that extra power seems worth celebrating, you may want to spring for the 2011 Challenger SRT8 392 Inaugural Edition. The special-edition model is available either in white with blue stripes or the inverse, but all cars will receive white leather seating with blue striped inserts, special emblems, trim accents, and a $500 voucher for Mopar accessories. Production is expected to be limited to 1100 cars.
