Jeep has unveiled the 2012 Grand Cherokee SRT8 at the New York Auto Show.

Looking decidedly aggressive, the high-performance model features a new front fascia, a body-color grille and a ventilated hood. Other highlights include LED daytime running lights, a dual exhaust system and 20-inch forged aluminum wheels with Pirelli PZero run-flat tires.

While the exterior changes are extensive, the cabin is more restrained as it has Nappa leather/suede sport seats, a flat-bottom steering wheel, and faux carbon fiber trim.

Power is provided by a 6.4-liter HEMI V8 that produces approximately 465 hp (347 kW / 471 PS) and 465 lb-ft (630 Nm) of torque. It enables the SUV to accelerate from 0-60 mph in 4.8 seconds, run the quarter mile in "mid-13 second range," and hit an electronically limited top speed of 155 mph (250 km/h).

To keep everything in check, the SUV is also equipped with a new adaptive damping suspension, a limited slip rear differential, and a Brembo braking system.

No word on pricing, but the Grand Cherokee SRT8 will start arriving at U.S. dealerships later this summer.
