On paper, the performance of the Jeep Grand Cherokee Trackhawk is just about dead-even with that of the Dodge Challenger SRT Hellcat Widebody. Both have supercharged, 6.2-liter Hemi V8s rated at 707 horsepower, and both can scoot to 60 mph from a stop in the mid-3-second range (3.5 seconds for the Jeep, vs. 3.4 for the Dodge). Where they start to differ appreciably is by the end of the quarter-mile stretch; Jeep claims that the 5,300-pound Grand Cherokee Trackhawk can jet down the drag strip in 11.6 seconds, where Dodge claims the 4,500-pound Challenger SRT Hellcat Widebody can do it in 10.9.
Of course, the real world quite often fails to replicate results from a controlled experiment, and that’s just what we see here when Hennessey Performance Engineering pits the heavier, AWD Grand Cherokee Trackhawk against the RWD Challenger SRT Hellcat Widebody. The crossover gets a better start than the coupe, pulling ahead by a handsome margin right off the line, although the Challenger does manage to reclaim some of that ground toward the end of the strip.
If the Challenger had managed a stronger start, we’ve little doubt that it would have won out in the end. But either way, no matter which vehicle placed first, when Hennessey decides to pit two 707-horsepower Mopars against one another at the drag strip, we all win.
