Hennessey Performance Engineering amped up the GMC Sierra Denali pickup truck, adding a 2.9L supercharger to its 6.2L V8, taking it from a stock 420hp up to a bonkers 700hp. Combined with a stage-1 off-road package, it gets a 6-inch lift, 20″ wheels, 35″ off-road tires, and a menacing GOLIATH front bumper with LED lighting.
THE BEST Gmc
Our hands behind the wheel of GMC’s confident and luxurious SUVs and trucks, we headed into the snowy mountains of Vail, Colorado. There, we explored some of the natural beauty, hit some awesome snowmobile trails, enjoyed a luxury ski resort, and dined on delicious local cuisine.
GMC’s 2020 Sierra pickup trucks offer an innovative bed made from a carbon fiber reinforced polymer. This makes them extremely durable and impervious to about everything. To prove this, they compared ordinary beds to theirs by flinging objects at them in hurricane-force winds. Suffice it to say, the CarbonPro won hands down.
We spent some time in Wyoming putting GMC’s 2020 trucks through their paces, including the Sierra 1500 AT4 on a dirt and rock course. It has a 2” lift, a 2-speed transfer case, Rancho monotube shocks, skid plates, a locking rear diff, and is now available with a 3.0L Duramax turbo diesel, making 277 hp and 460 lb-ft. of torque.
We spent a day taking GMC’s latest full-size pickup on a road trip through Newfoundland. We found a truck that looks great, drives great, and packs an array of whiz-bang features, from its versatile Multigate tailgate, to its Prograde trailering tech. Full review on 95octane.
