If ever there was a need for an SUV that turned 0-60 mph in less than five seconds, Jeep had it in the new 2006 Grand Cherokee SRT8. Equipped with a 6.1-liter Hemi V-8, it was faster than even a Porsche Cayenne Turbo. Ultimate SUV though it may have been, it was only part of the Grand Cherokee lineup, which also included a V-6 and two other V-8’s in the base Laredo, the Limited, and the new uber-luxury Overland trim level. Four wheel drive was standard on all Grand Cherokees, which also had ABS and stability control standard, whether or not they were the world’s quickest SUV.
