For 2015, the Challenger SRT with a Hellcat engine is propelled by the new supercharged 6.2-liter HEMI V-8. Its 600-plus horsepower rating will be the highest of any V-8 engine in Chrysler Group's celebrated history. The all-new V-8 engine can be mated with an upgraded six-speed manual transmission or a beefy, new TorqueFlite eight-speed automatic -- the first such gearbox ever offered in the Dodge Challenger SRT's time-honored segment.

This new HEMI® Hellcat engine is Dodge and SRT's first application of V-8 supercharger technology, delivering the full brand experience with fresh potency.

The breakthrough supercharged engine features a forged-steel crankshaft with induction-hardened bearing surfaces. The result is a crank so well-engineered it can withstand firing pressures of 110 bar (1,595 psi) -- the equivalent of five family sedans standing on each piston, every two revolutions. And its unique, specially tuned crank damper has been tested to 13,000 rpm.

High-strength, forged-alloy pistons -- developed using advanced telemetry measurement -- are coupled to powder-forged connecting rods with high-load-capacity bushings and diamond-like-carbon-coated piston pins.

The new supercharged 6.2-liter HEMI V-8 has premium-grade, heat-treated aluminum-alloy cylinder heads that are optimized for superior thermal conductivity. And its die-cast aluminum rocker covers are HEMI Orange.

In addition to the supercharged HEMI V-8 in the Challenger SRT Hellcat, the new 2015 Dodge Challenger SRT model also gets a power boost with upgrades to the 392 HEMI V-8. Horsepower climbs to 485 from 470, while peak torque jumps to 475 lb.-ft. from 470 lb.-ft.

The 392 also can be mated with a new TorqueFlite eight-speed automatic or the proven six-speed manual transmission.
