So what we have here are two legends — one old, one new. Despite 40 years of automotive progress, both share a similar powertrain philosophy: a pushrod V8 driving a manual transmission which in turn drives the rear wheels via a limited-slip differential.With a 6.1-liter V8 good for 425 horsepower and 420 pound-feet of torque, a six-speed manual transmission and independent rear suspension, the 2010 Dodge Challenger SRT-8 is a thoroughly modern pony car. The Hotchkis-modified 1970 Dodge Challenger, however, employs a period-correct 340-cubic-inch (5.6-liter) V8 with three two-barrel carburetors. The powertrain tweaks of this Hotchkis car are completed by a Tremec five-speed manual transmission and 8.8-inch rear end with Chrysler’s 3.55:1 Sure-Grip limited-slip differential
In 1970 Dodge Challenger was introduced and intended to compete against many of the pony cars out there, specifically the Ford Mustang and the Chevy Camaro. The Challengers were known for their wide variety of trim levels and options. The performance oriented Callenger R/T (Road and Track) came with a 383 (roughly 6.25 liters) V8 that put out around 335 horsepower. This modern two-door coupe is very similar in design to the original Challenger even though its dimensions are larger all around. For the 2008 model year and the reintroduction of the Challenger, all models were SRT8 trim meaning that they were performance oriented only.
