Dodge expanded what was formerly the Challenger SRT8 into two new 2015 models; the SRT 392 and SRT Hellcat; each of which features a powerful V-8 engine, high-performance mechanical equipment, and sporty exterior and interior design features. The new Hellcat model tops the Challenger range with 707 horsepower.
Dodge's retro-inspired Challenger five-passenger muscle car sees its first significant revision for the 2015 model year. All new Challenger models receive new front-end styling, eight-speed automatic transmissions for improved efficiency, and more available interior and safety technology.
The SRT 392 trim level packs a 6.4-liter naturally aspirated HEMI V-8 engine with 485 horsepower and 475 foot-pounds of torque, giving it 110 more horsepower than the R/T model with its smaller V-8. Other performance enhancements include six-piston Brembo brakes with 15.4-inch slotted and ventilated rotors, an adjustable Bilstein suspension system and 20-by-9.5-inch forged aluminum wheels. The SRT 392 also sets itself apart a revamped interior with sportier seats and special badging, plus an 18-speaker, 900-watt Harman Kardon premium audio system.
The all-new Challenger SRT Hellcat makes the most power of any production car from an American automaker thanks to a supercharged 6.2-liter HEMI V-8 with 707 horsepower and 650 foot-pounds of torque. The Hellcat receives most of the same upgrades as the SRT 392 then adds on a cold-air intake system, a vented lightweight aluminum hood with an air extractor, an even sportier adjustable Bilstein suspension, and a stronger eight-speed TorqueFlight automatic transmission. Pricing for the SRT 392 starts at $45,995, while the SRT Hellcat comes priced from $59,995, as of April 2015.
