The Challenger is a major salvo in the Horsepower Wars, offering muscle-car metal and seriously awesome engines. The 6.4-liter Hemi V-8 makes 485 hp and 475 lb-ft; choose either a six-speed manual or eight-speed automatic. The aptly named Hellcat has a supercharged 6.2-liter V-8 good for 707 hp and 650 lb-ft, with either a six-speed manual or eight-speed automatic. The automatic is faster, hitting 60 mph in 3.6 seconds, while the manual is more fun and still quick doing 0–60 in 3.9 seconds.
The stout SRT 392 packs a 485-hp Hemi V-8, and the notorious SRT Hellcat possesses a 707-hp supercharged Hemi V-8. Both have substantial brakes and an adaptive suspension; a standard six-speed manual transmission or a proficient eight-speed automatic funnels power to the rear wheels. The Hellcat Widebody has a distinct appearance thanks to flared fenders and wider wheels and tires. These power-crazy Challengers still provide exceptional comfort with a spacious cabin and plentiful standard features. The diabolical Dodges generate nostalgia and release our inner delinquency—which includes the effortless roasting of rear tires. Bad-asses indeed.
Every Challenger received an updated Uconnect infotainment system. The 8.4-inch touchscreen with navigation—standard on SRT models—added multitouch gestures. New exterior paint colors included Green Go, Yellow Jacket, Destroyer Grey, and Octane Red; White Knuckle and Contusion Blue were renamed carry-over colors. Both SRT cars added an illuminated steering-wheel logo. The Hellcat received new badging, and its standard 20-inch wheels were redesigned to save 16 pounds.
Major redesigns occur every five years or so; not much changes in between. Dividing them into generations provides more meaningful distinctions in the shopping process.
