The Challenger SRT Hellcat arrived for 2015 with a supercharged 6.2-liter HEMI V8 rated at 707 horsepower. That year's refresh brought a grille with cues from the 1971 Challenger, quad LED halo headlights and LED taillights. Six-piston Brembo calipers grip 15.4-inch front rotors. This one is a 2015 Hellcat in grey over a black interior, with a manual gearbox.
