The Dodge Challenger SRT8 is a beastly muscle car that recently gained a sizable dose of added power - 50 horsepower to be exact - thanks to an additional three-tenths of a liter of displacement, earning the new name - Challenger SRT8 392.
As the name implies, this top=spec Challenger model comes equipped with a 392 cubic-inch V8. A quick rundown of the numbers reveals a 6.4-liter displacement, hitting the rumored figure right on the head. The new 6.4-liter HEMI replaces the outgoing 6.1-liter V8 in all of Chrysler's high-powered SRT8 models.
Thanks to that added displacement, the Challenger SRT8 392 cranks out 470 horsepower and 470 lb-ft of torque. The latter figure is 90 lb-ft better than the Challenger’s previous engine, adding a welcome kick in the pants to the straight line acceleration department. In fact, the SRT8 392 can scoot from a dead stop to 60 miles per hour in under five seconds.
If quarter mile races are more your thing, know that this coupe can run the quarter in mid 12's with the automatic transmission, or high 12's equipped with the row-it-yourself gearbox. Top speed is an impressive 182 in the manual and 175 with the automatic.
With all that power and displacement fuel economy is obviously not the primary concern of the vehicle's engineers, but it wasn't forgotten either. Both transmissions will return 14 city mpg, while the manual bests the automatic by one mpg for a highway rating of 23.
Speaking of transmissions, it should be known that the manual found in the 392 is no five-speed, but a six-speed TR-6060 Tremec unit with a dial-disc high performance clutch - the same one tested to the limits in the 2008 Dodge Viper SRT10.
For those more interested in cruising than racing, the automatic comes in five-speed flavor that includes both "Normal" and "Sport" modes. Sport mode will keep the transmission in the gear a bit longer, maximizing power at the cost of efficiency.
However, the latest Challenger isn’t all about going fast in a straight line as Chrysler has equipped the modern day muscle car with revised steering and an updated suspension. Changes include highly damped shocks, re-calibrated suspension geometry, quicker steering ratios and new negative camber settings. As a result, Chrysler says the Challenger is more tossable than ever, and even clocked .93g of lateral acceleration on the skid pad.
Keeping the SRT8 where it should be are either 20x9 forged aluminum in a seven-spoke design or 20x9 forged aluminum wheels with satin black painted pockets, either wrapped in Goodyear RSA all-season tires as standard.
Optional are Goodyear F1 Supercar three-season tires that kick the performance up a notch at the expense of longevity and wet handling.
Behind those wheels are 14.2-inch front and 13.8-inch rear vented and slotted rotors being grabbed by Brembo four-piston fixed calipers finished in red, of course.
Other exterior styling cues include '392 HEMI' badges, quad exhaust outlets, a new front spoiler and a body-painted rear decklid spoiler.
The latest Dodge Challenger SRT8 392 features more than 35 advanced safety and security features, including standard Keyless Enter-N-Go and three-mode electronic stability control (ESC) with segment-exclusive Ready Alert Braking and Rain Brake Support safety features to improve overall vehicle handling and performance.
In addition, safety is provided by standard front-row reactive head restraints, standard full-length side-curtain air bags, driver’s knee bag and standard front seat-mounted side-thorax air bags offer enhanced occupant protection to passengers in the event of a collision.
Key Competitors
As the range-topping model in the Challenger lineup, the SRT8 392 competes against powerful rivals like the 650 horsepower Ford Shelby GT500 and the 580 horsepower Chevrolet Camaro ZL1.
