There are very few SUVs that can outperform or outclass the Jeep Grand Cherokee, and it has been this way for a long time. This SUV will come with a high-powered engine that's 6.4 or 6.2 liters in size. Forced induction has been added to the 6.2-liter V8, and it will blast from zero to 60 mph in 3.5 seconds.
