Who says a 6,000+ lb SUV that can carry seven-passengers and or can offer you a crazy amount of cargo space has to be sluggish when it comes to performance. The guys at Hennessey Performance Engineering definitely don't believe in that thought and that's why they decided to come up with a package for the 2015 GMC Yukon Denali XL (extended version) that proves a huge point.
When the Hennessey HPE650 performance package is applied to the Yukon's 6.2-liter EcoTech Supercharged V-8 it's pumps out a monster 650-hp. Now that 650-hp is not just designed for hauling the family around town or towing things, it's designed to go fast as well. In fact it performs so well it gets 0-60 mph in 4.7 seconds while toppling the standing quarter-mile in 13.3 sec. at 113 mph, not bad for a vehicle that size.
With that kind of power you don't ever have to worry about your big SUV having troubles getting in-and-out of traffic even if you were to be towing something that is quite big, like a RV. You get all the comforts of a SUV on the inside, but the power capabilities of an up-scale four-door sedan that's designed to go fast. The Hennessey Yukon is just a great combination of power, comfort and versatility.
The cool thing is that Hennessey Performance has packages for the Cadillac Escalade and the Chevy Suburban as well. So if you're driving an Escalade, Suburban or a Yukon Denali and you think you could use a little more power under your right foot, a Hennessey HPE650 performance package will give you more than enough power to tool around with.
