Video: John Hennessey Hustles Supercharged GMC Yukon Denali XL Down Dragstrip
Jumbo SUV Posts Impressive Times
There are some things that are uniquely American. Among them are the truly fullsize body-on-frame truck-based SUV. Sure, there’s the Toyota Land Cruiser, the Mercedes-Benz GL, and the Nissan Patrol, sold here as the Infiniti QX80. However, the originator of the genre still dominates the segment and that’s General Motors’ lineup of the Chevrolet Tahoe and Suburban, the GMC Yukon and Yukon XL, and Cadillac Escalade. The proven performance of these workhorses has collectively made them the best-selling vehicles in the fullsize SUV segment by a long shot. Of course, anything good can be made better by the infusion of more horsepower, and that’s where Hennessey Performance Engineering (HPE) comes in. HPE will hot rod just about any domestic truck, SUV, or muscle car to go from great to ridiculous levels of performance.
The stock GMC Yukon Denali is no slouch with 420 hp and 460 lb-ft of torque, but an infusion of more than 200 hp sure can’t hurt. Equipped with the Hennessey supercharger system, the short-wheelbase Yukon Denali with the 6.2L zipped from 0-60 mph in just 4.5 seconds. Curious to see what the big Bertha Yukon XL would do with a similar setup, John Hennessey took the long-wheelbase model to the track. While the 0-60 performance came up just short at 4.7 seconds, the quarter-mile still flashed by in an impressive 13.4 seconds at 112 mph. Of course, to top off that performance and celebrate good ol’ American V-8 supercharged horsepower, the video ends with a burnout. Check out the video below.
