2015 HPE650 Supercharged GMC Sierra Pickup TruckSeptember 17th, 2014
In this case, we’re looking at a customized version of the full-size 2015 GMC Sierra. Hennessey took GM’s already substantial 6.2-liter V8 engine and designed a 2.9-liter supercharger, which boosts the engine from a stock 420 horsepower to a supercar-like 650 horsepower. The mod includes high-flow cylinder heads and an upgraded cam shaft, as well as a new stainless steel exhaust system, which provides an imposing, deep exhaust note.
For those of you wondering, Hennessey also offers performance upgrade packages for the Chevy Silverado, Tahoe, and Silverado, GMC Yukon, Cadillac Escalade, Lexus LX 570 and the Ford F-150 Raptor SVT.
