The supercharger on the Hellcat’s 6.2-liter V8 engine makes 11.6 psi of boost, while the forged-steel crankshaft and high strength connecting rods are engineered to withstand 1,595 psi, or the equivalent of nearly 20,000 pounds, pressing on the piston tops every two crank rotations.
The Dodge Challenger Hellcat SRT has a stated top speed of 199 mph. Like the horsepower figure, you can find vehicles with higher top speeds, but only at substantially higher prices.
Speaking of reigning in power, the Hellcat is the first Dodge to feature two keys — a red and a black version. The red key unleashes all 707 horsepower and every one of the Hellcat’s numerous performance settings for suspension, steering and traction control.
With 707 horsepower and 650 pound-feet of torque the SRT Hellcat’s supercharged 6.2-liter V8 can burn through 1.5 gallons of gas per minute at peak performance. That rate would theoretically drain the fuel tank in 13 minutes.
The Hellcat’s interior includes unique red background lighting in the gauge cluster to distinguish it from other Challengers.
