Hennessey Performance just held a drag race between their two upgraded Jeep Grand Cherokee Trackhawks and a stock model to show just how powerful their SUVs are.

This is probably an entirely unnecessary video, but it does show just what the ingenuity of Hennessey Performance can accomplish. And it shows a stark contrast between each stage of upgrades, which is always useful.

Plus it’s a great excuse to line up three Jeep Trackhawks for a shootout.

First, there’s the stock Jeep Grand Cherokee Trackhawk. Gone is the standard 3.6-L Pentastar V6 in favor of the Hellcat’s 707 hp 6.2-L supercharged V8. Zero to sixty is done in just 3.5 seconds--almost the same as a Porsche 911 GT3--with a top speed of 180 mph. It is certainly one of the fastest SUVs ever built, if not quite the best handling one.

Next we have Hennessey’s HPE850 upgrade. As the name implies, the HPE850 gets 850 horses (852 hp, to be exact), along with 845 lb-ft of torque. Zero to sixty is done in just 2.9 seconds with a top speed that’s probably not much faster than 180 mph since wind resistance is exponential.

Finally, we have the HPE1000. Thanks to a larger 4.5-L supercharger, the HPE1000 gets 1012 hp and 969 lb-ft of torque. Zero to sixty is done in 2.7 seconds, which is faster than a Porsche 911 GT2 RS. We’re not sure why everything needs to be compared to Porsches today, but it seemed like a good benchmark.

Hennessey performs several races, and they all go pretty much exactly as you’d expect. The HPE1000 shoots off the line like a rocket-powered apartment building, leaving the stock and HPE850 to catch up. Surprisingly, the HPE850 doesn’t quite power away from the stock Trackhawk as quickly as you’d think on a few races, but maybe the driver just had a bad start.

If you want the fastest house to move, then the HPE1000 is the Trackhawk for you.
