The new 2015 Dodge Charger SRT Hellcat is powered by the new supercharged 6.2-liter HEMI® V-8 engine. Its 707 horsepower matches the highest rating of any V-8 engine in Chrysler Group’s celebrated history – that of the 2015 Dodge Challenger SRT Hellcat – making it the quickest, fastest and most powerful production sedan in the world, as well as the most capable and technologically advanced four-door muscle car in America.
The unrivaled four-door performance numbers tell an impressive story with an NHRA-certified, quarter mile in 11.0 seconds, 0-100-0 mph in under 13 seconds, and a top speed of 204 mile per hour (mph).
The all-new supercharged V-8 engine is mated to the beefy new TorqueFlite 8HP90 eight-speed automatic transmission.
This new Hellcat engine is Dodge and SRT’s first application of V-8 supercharger technology, featuring 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 supercharged 6.2-liter HEMI V-8 has premium-grade, heat-treated aluminum-alloy cylinder heads, which are optimized for superior thermal conductivity. And its die-cast aluminum rocker covers are HEMI Orange.
