As is the case with everything that comes from Street and Racing Technology, Chrysler’s in-house tuning division, the SRT8’s main selling point is still the engine, so the transformation from the previous generation model starts with the new 6.4-liter HEMI V8, which puts out 465 horsepower and 465 pound-feet (630 Nm) of torque, 80 lb-ft (108 Nm) more than the old 6.1-liter unit. More importantly, the company says the twisting power is now available across a significantly wider rpm range.
The engine should be more frugal, as the fitting of Dodge’s Fuel Saver tech will allow it to run on just four cylinders when not under significant load. We’ve heard that before, with the old 300C, so we’ll wait for the official figures before telling you this red devil can be called fuel efficient.
The HEMI V8 now sends its power to the rear wheels through Chrysler's W5A580 five-speed automatic transmission, and you can now select your own gears now, using either the AutoStick or the steering wheel-mounted paddle-shifters.
In the looks department, the 2012 SRT8 comes with a new set of five-spoke 20-inch aluminum and polished wheels, new front fascia, LED tail lamps and huge four-inch wide dual exhausts at the back. Interior changes and additions include a flat-bottom steering wheel, bolstered seats and a 900-watt, 19-speaker audio system from Harmon Kardon.
The car will make its official debut at the Chicago Auto Show today and will be available in the fall of this year as a 2012 model. No pricing information has been released yet.
