Despite their weight, SUVs can still offer a great deal of fun if treated properly. To be more precise, if you modify them the way they should be modified, in order to give the best performance. And when it comes to modifying vehicles, Hennessey Performance Engineering is one of the best tuning houses out there. The vehicle featured in the video below has been modified by this famous American tuner. It is a word of the 2015 GMC Yukon XL Denali – a massive SUV that has room for seven people plus cargo storage!
This spaciousness has also a con – this vehicle weighs almost 6,000 pounds but that is not a problem for the team of Hennessey Performance Engineering! They added a SUPERCHARGER to the already massive 6.2 liter V8 engine! Now, this particular 2015 GMC Yukon XL Denali delivers 650 BHP at 5,500 RPM as well as 658 pound-feet of torque at 4,200 RPM!
In addition to this, the video below is a test to determine the 0 to 60 time of this huge SUV. The driver is of course the founder of Hennessey Performance Engineering, John Hennessey. He managed to go from 0 to 60 miles per hour in amazing 4.7 seconds!
