Holy crap. That's a hell of a vehicle. Full-time AWD.

"Powered by a 6.1-liter HEMI producing 415 horsepower (85 more horses and 25 percent more power than the 5.7-liter HEMI-equipped 2006 Jeep Grand Cherokee) and 410 lb.-ft. of torque, the all-new 2006 Jeep Grand Cherokee SRT8's performance numbers include 0-60 mph in under 5 seconds, 0-100-0 mph in the low 19-second range, and 60-0 mph braking distance of approximately 125 feet."

"With a 6.1-liter SRT HEMI(R) V-8, Jeep Grand Cherokee SRT8 offers ultimate SUV performance * 0-60 mph in under 5 seconds - quicker than Porsche Cayenne Turbo, BMW X5 * Proven Jeep capability with SRT performance provides astonishing on- road and all-weather ability and power * Jeep Grand Cherokee SRT8 the first four-wheel drive SRT vehicle, the first Jeep-branded SRT vehicle."

Dang, that thing looks bad!

There's a car museum in Reno, NV that has a V12 Ferrari engine shoved inside a Jeep Wrangler(?), the older ones that are about the size of a Suburban.
