The Dodge muscle car arsenal is reloaded with the new 2015 Challenger -- delivering up to 485 best-in-class horsepower, all-new R/T Scat Pack and 392 HEMI Scat Pack Shaker models, segment-first TorqueFlite eight-speed transmission standard and an all-new interior.

The 2015 Challenger is available in eight trim levels: SXT, SXT Plus; R/T, R/T Plus, R/T Shaker, R/T Plus Shaker, R/T Scat Pack; and 392 HEMI Scat Pack Shaker.

Inspired by the iconic 1971 Challenger, all 2015 models take on a bold new appearance that draws on the 1971 model's split-grille and split-tail lamp cues, updated to 2015 with four signature LED headlamp halo surrounds offset by piano black trim.

Challenger SXT and SXT Plus models feature the award-winning 3.6-liter Pentastar V-6 engine, which delivers 305 horsepower and a responsive 268 lb.-ft. of torque.

For Dodge fans looking for affordable muscle, the 2015 Challenger R/T lineup features the legendary 5.7-liter HEMI V-8 engine, which delivers up to 375 horsepower and 410 lb.-ft. of torque with a six-speed manual transmission.

With a best-in-class 485 horsepower and 475 lb.-ft. of torque, the 2015 Dodge Challenger R/T Scat Pack and 392 HEMI Scat Pack Shaker models deliver up to 113 more horsepower and 65-lb.-ft. leap in torque compared with the 5.7-liter Challenger models.

The Shaker returns for 2015 on the R/T and the R/T Plus models, bringing the iconic engine-mounted, fully functional cold-air induction Shaker hood with up to 410 lb.-ft. of torque and unique wheels, interior trim, exterior styling cues and more.

The 2015 Dodge Challenger's segment-first eight-speed automatic transmission delivers world-class precision and fuel efficiency, along with a new electronic shifter, sport mode and paddle-shifting capabilities for more performance, as well as an improvement in fuel economy.
