The
all-new Charger will once again receive a slight makeover later this
fall, although this time it'll get musclecar mascara from Chrysler's
Street and Racing Technology (SRT) team. Not only is the new 2012 Dodge
Charger SRT8 more powerful than the last go-fast rendition, but
according to preliminary test data, it's more efficient, too.
The
new SRT8 Charger's improved efficiency is achieved in part by the
addition of Chrysler's adaptive valve exhaust system and Fuel Saver
technology. The latter switches the all-new 6.4-liter Hemi V-8 into a
four-cylinder mode that's activated over a wider rpm range, thus
minimizing consumption. By exactly how much has yet to be announced, but
for a reference point, the last Challenger SRT8 powered by the
6.1-liter V-8 was rated 13/19 mpg city/highway. An active intake
manifold and high-lift camshaft on the 2012 Charger SRT8 optimize
low-end grunt for even more speed when you want it.
Each
of the SRT8's 465 horses and 465 pound-feet of torque are routed to
sticky 20-inch rear rubber through the brand's well worn W5A580
AutoStick five-speed automatic. Yes, we know, it's no pistol-grip
six-speed manual (say, from the Challenger SRT8 392), or even a
six-speed slushbox, but SRT has included a first-ever paddle shifting
function to make the aging tranny more entertaining.
Even
with the questionable gearbox in place, Chrysler reckons the SRT8 can
sprint to 60 mph from a standstill in the high-4 second range, achieve
0.88 g on the skidpad, and top out at an estimated 175 mph. Quarter-mile
times should be in the high-12 second range, Chrysler says.
Good
thing there are four-piston Brembos to clamp down hard on 14.2-inch
front/13.8-inch rear slotted rotors. The massive binders utilize
Chrysler's Ready Alert Braking system that positions pads closer to the
rotors when a collision is anticipated by onboard telemetry. Each corner
also gets redesigned 20-inch forged aluminum wheels that sport black
accents to emphasize their mirror-like faces.
An
SRT first, the adaptive damping suspension adjusts stiffness levels
based on driver inputs and road conditions. When left in Auto mode, the
suspension's ECU calibrates all four corners to a softer level; toggle
to Sport for a tauter road feel. Engineers installed a beefier power
steering system for direct, yet livable communication.
