With 707 horsepower and a quarter-mile time of 10.8 seconds, the new 2015 Challenger SRT Hellcat is the most powerful muscle car ever. Dodge describes their new Challenger as a “true GT car,” offering race-ready performance alongside the ability to drive your family cross-country.
The key to the Challenger SRT Hellcat’s outstanding performance is its incredible motor. The supercharged 6.2-liter “Hellcat” HEMI V-8 puts out 707 horsepower and 650 lb-ft of torque, its forged-steel crankshaft can withstand 1595 psi of firing pressure (the equivalent to five family sedans), and its specially-tuned crank damper has been tested to 13,000 RPM. The Hellcat’s pistons are high-strength forged alloy, its piston pins are carbon-coated for diamond-like strength, and its bearing surfaces are induction-hardened.
For all the power and engineering of its 6.2-liter V-8, there’s more to the Challenger SRT Hellcat than its engine. The rest of the drivetrain certainly hasn’t been neglected – the Hellcat is available with a six-speed manual transmission or an eight-speed automatic (with paddle shifters), it rides on 20″ lightweight forged-aluminum wheels, and its front brakes are 15.4″ Brembo dual calipers with six pistons.
Dodge hasn’t neglected the electronics either – in addition to electronic stability control and a broad array of available safety features, the Challenger SRT Hellcat has a number of features designed to help you get the best performance out of it – and to keep anyone else from being able to take advantage of it. Dodge’s “Drive Modes” system allows you to customize engine, transmission, brake, and chassis characteristics, in order to tailor the entire car to your preferences and the driving situation you’re facing. The Hellcat also comes with two key fobs – you can use the red one to unlock its full 707 horsepower, while anyone you give the black key fob to will be limited to a mere 500 horsepower. Perhaps most vitally, the Hellcat comes with a “Valet Mode” – by entering a passcode, you can severely restrict the engine’s performance, lock your vehicle in the “Street” Drive Mode, and disable launch control – just in case you’re worried about others being tempted by its performance.
