2012 Jeep Grand Cherokee SRT8 at the 2011 New York Auto Show Review and News

• Competes with: Infiniti FX50, Porsche Cayenne
• Looks like: A sleeper that's anything but sleepy
• Drivetrain: 465-hp, 6.4-liter V-8 with five-speed automatic transmission; all-wheel drive
• Hits dealerships: Third quarter 2011

Given how impressive the previous-generation Jeep Grand Cherokee SRT8 was, we can't wait to drive the 2012, which is based on a more competent, modern chassis that made its debut for 2011. Last sold as a 2010, the SRT8 had a 6.1-liter V-8 that made 420 horsepower and 420 pounds-feet of torque. The 6.4-liter V-8 in the new one makes 465 hp and 465 pounds-feet that propel the truck to 60 mph in 4.8 seconds, according to Jeep.

Using cylinder deactivation that wasn't previously available on SRT8 versions of the Hemi V-8, the 2012 model is claimed to improve highway mileage by 13 percent despite the increased power. The previous generation achieved an uninspiring 12/16 mpg city/highway. The transmission is a five-speed automatic with AutoStick gear selector plus steering-wheel shift paddles.

The SRT8's sport suspension now includes adaptive shock absorbers that are integrated into the Selec-Trac system. The knob controller includes a Track setting along with Sport, Auto, Snow and Tow. Each mode customizes the suspension, transmission shift characteristics, stability system, traction control, transfer case and other parameters. The brakes are Brembo-brand six-piston front and four-piston rear calipers with 15-inch front and 13.8-inch rear vented discs.
The SRT8 is distinguished by LED running lights, a body-colored grille, a gloss-black lower bumper segment and exclusive 20-inch wheels. Around back, 4-inch-diameter dual chrome tailpipes emerge from a gloss-black diffuser. A liftgate spoiler improves aerodynamics.
Interior upgrades include SRT-branded Nappa leather sport seats and steering wheel, carbon-fiber trim and racing-style pedals. The 2012 SRT8 monitors and displays acceleration times, braking distance and g-force.
