The 2012 Jeep Grand Cherokee SRT8 will be unveiled for the first time on Wednesday at the 2011 New York Auto Show. According to the automaker, it’s the fastest Jeep ever built.
Jeep is making some pretty serious claims about the latest version of the Grand Cherokee, too: zero to 60 in 4.8 seconds, zero to 100 and back in the mid-16-second range and the quarter-mile in the mid-13-second range, a 155-mph top speed and 60 to zero in 116 feet.
Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group’s all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers an estimated 465 horsepower and 465 lb.-ft. of torque – an improvement of 45 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces.
The model is 13% more economic compared to its predecessor thanks to a new active exhaust system that lets Chrysler’s cylinder-deactivating Fuel Saver Technology operate over a wider RPM band. An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wider and improved rpm band.
Ride and handling improvements come courtesy of the body’s 146 percent increase in torsional stiffness and a standard adaptive damping suspension, which is controlled by the SRT8’s new Selec-Track system. With five different settings (auto, sport, tow, track and snow), the Selec-Track system adjusts stability control, damping, transmission shifts, torque proportioning, throttle response and electronic limited-slip differential for optimal performance according to conditions.
All the handling improvements together with beefier 295/45ZR-20 Pirelli PZero tires (up from the previous staggered 255/45R-20 front, 285/40R-20 rear Goodyear Eagle RSA), have Jeep calling the 2012 Grand Cherokee SRT8 its best handling vehicle to date capable of pulling 0.90 g on the skidpad.
Stopping power for the 2012 Grand Cherokee SRT8 comes courtesy of new SRT high-performance Brembo brakes with four-wheel anti-lock brake system (ABS).
Stopping distance performance of 116 feet from 60-0 mph is made possible by new red-painted, Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 15-inches (front) and 13.8-inches (rear).
Inside there’s a list of standard features as long as your arm, including SIRIUS satellite radio, a DVD and MP3-capable stereo and new steering wheel-mounted paddle shifters. Options include a 19-speaker, 825-watt Harmann-Kardon stereo complete with a 10-inch subwoofer, a dual-pane tinted sunroof and a power liftgate.
