The 392-cubic inch (6.4-liter) HEMI® V-8 offers 470 horsepower (351 kW) and 470 (637 N.m) lb.-ft. of torque. The torque band is incredibly flat providing for strong standing starts and improved straight-line performance all through the rpm range. A sophisticated active intake manifold together with high-lift cam with phasing gives maximum low-end torque and high-end power while still delivering up to 23 miles per gallon while driving with the standard stick shift. Performance-tuned engine brackets improve idle stability and ride control at any speed.
Standard Fuel Saver Technology (four cylinder mode) in automatic gearbox outfitted models enables the engine to run cheaply on four cylinders or utilize the power of all eight cylinders if needed. The EPA fuel economic system miles per gallon (mpg) (City/Hwy) ratings for the 2012 Dodge Challenger SRT8 392 are 14/22 for automatic transmission models and 14/23 for manual-transmission models.
The 2012 Dodge Challenger SRT8 392 comes with a standard Tremec TR-6060 six-speed manual transmission and a dual-disc high end clutch - a proven performer that was first presented on the 2008 Dodge Viper SRT10®.
The optional five-speed automatic transmission features new, standard steering wheel mounted paddle shifters that join the center console mounted Auto Stick, enabling a range of lively shifting equally on the road and the race track. Each method provides the driver with the possibility to manually select certain gears on the transmission.
Sitting a half-inch less than non-SRT models, the 2012 Challenger SRT8 392 rides on either the conventional five-spoke, 20 x 9-inch fully forged aluminum wheels or available seven-spoke, 20 x 9-inch lightweight forged aluminum wheels with satin black colored pockets. Standard Goodyear RSA All-Season tires or available Goodyear F1 Supercar Three-Season accentuate the performance design cues and deliver serious gripping functionality and control.
The standard SRT performance brake package delivers world-class stopping power of 60 to 0 mph in just 117 feet from 14.2 inch (front) and 13.8 inch (rear) vented/slotted rotors with four-piston Brembo fixed calipers painted red. The three-mode electronic stability control system with knockback mitigation comes with a four-wheel ABS, all-speed traction control, electronic brake-force distribution, Brake Assist and Hill-start Assist (HSA).
