20. Jeep Grand Cherokee Trackhawk
There were fast SUVs before Jeep introduced the Trackhawk. However, this glorious machine deserves a place on this list for two reasons. First, for the 707 Hellcat Hemi engine under the hood. Second, its 3.4-second 0 to 60 mph time makes this SUV faster than some supercars (via Jeep).

The Trackhawk is a brutal machine that is highly unusual and influential. It is a proper muscle car in SUV form. That shows how a high horsepower Hemi engine can make anything a proper muscle car, even a full-size SUV.
