The 6,2-litre Hellcat V8 powering the car is the most powerful Dodge V8 ever and the first HEMI to make use of a factory-installed supercharger.
Dodge stated that the new Hellcat has so much power that it requires two keys. The black key fob limits the driver to 'just' 500hp (372kW), while the red key unleashes the full stable.
The big, grumbling HEMI V8 handles its massive torque with help from the buyer's choice of a Tremec TR6060 six-speed manual or a new TorqueFlight eight-speed automatic. Drivers can tune the ride by way of sport, track or default driving modes and tweak it even more with a personalised 'custom' mode option.
The hard edges and boxy shape of the Challenger keep it from being poster-pretty in terms of aerodynamics, but the designers did spend a lot of time in the wind tunnel optimising the 2015 Challenger's form. The Hellcat includes a large front increasing downforce, aero-optimised side sills and a high rear spoiler. Its lightweight aluminium bulge hood has an intake and dual air extractors.
The Challenger SRT Hellcat comes standard on 'Slingshot' split-seven spoke forged-aluminium wheels with P275/40ZR20 Pirelli P Zero Nero tyres that come screeching to a stop behind a high-performance braking system with all-new 390mm Brembo rotors and six-piston callipers up front.
Inside, the Challenger SRT Hellcat is outfitted with a fully modern cockpit touched up with elements inspired by the 1971 Challenger. Smack in front of the driver, a 7" driver information display offers a customisable read-out. That display is flanked by old-fashioned analogue gauges that tie the look into the 1970s.
Leather wrapped surfaces and aluminium trim finish off the look.
Dodge will manufacture the 2015 Challenger SRT Hellcat at its Brampton, Ontario plant, getting it into dealerships in the third quarter of 2014. The company has not yet released pricing.
