The 2015 GMC Yukon XL Denali is an impressive vehicle in its own right. But what happens when you take that luxurious beast and plug in a 2.9-liter supercharger system, high flow intercooling system, and Hennessey Performance’s unique expertise in the art of making fast things go even faster? As you’ll see below, 650 horsepower and an incredible 4.5-second 0-to-60 time.

Using “Precision”: To advertise the 2015 GMC Yukon Denali and Yukon XL Denali

In the video above, mad scientist genius John Hennessey talks a bit about what makes the 2015 HPE650 Supercharged GMC Denali XL such an experiential drive. Then, at about the 3:02 mark, he gets behind the wheel and takes it for a spin. You can practically feel it from wherever you’re sitting.

And then, at 6:45, he gets the Denali XL onto a drag strip and pits it against a 2015 Dodge Challenger Hellcat. While the 707-horsepower Hellcat eventually gets the edge, the full-size-and-then-some SUV uses a cleaner start to stay out ahead for longer than any SUV reasonably should.

If you own a 2015 GMC Yukon XL equipped with a 6.2-liter V8 and want it to be even more ridiculous, Hennessey Performance offers 550-horsepower, 600-horsepower, and 650-horsepower upgrades. And why wouldn’t you want all that power?
