About Dodge Challenger
You could be forgiven for thinking the 2015 Dodge Challenger muscle car was all-new. The wonderfully refreshed exterior gets a new nose and tail. The interior, finally, boasts a modern design that incorporates Chrysler's Uconnect infotainment system and a much-needed backup camera. But the real news is under the hood. The standard engines all return: a 3.6-liter V6, a 5.7-liter V8, or a 6.4-liter V8 in the SRT, and all are mated to an excellent 8-speed automatic transmission. But wait, as they say, there's more. The 2015 Dodge Challenger SRT Hellcat debuts with a supercharged 6.2-liter Hemi V8 capable of an incredible 707 horsepower. That not only out-muscles the Chevrolet Camaro and Ford Mustang, it makes the Hellcat the most powerful American production car ever.
