Hennessey Performance is known for building over-the-top power upgrades for already quick performance vehicles. The company’s latest project is no different – an 800-horsepower Cadillac Escalade with its HPE800 package

Oh, and it’ll outrun a 2018 Chevrolet Camaro ZL1 1LE on an unprepped drag strip.

The video shows the run from multiple angles as the 5,700-pound, three-row SUV hooks up off the starting line and outguns the Camaro. The Caddy’s advantage is its hand-built, stroked 6.8-liter V-8 stacked with a supercharger. Matching its 805 horsepower at 5,500 rpm is an equally impressive 812 pound-feet of torque at 4,000 rpm. Traction isn’t an issue thanks to its full-time 4WD system that provides a spin-free launch.

Here, in this one run, the Escalade pulls several car lengths on the Camaro. Now, it’s clear the 650-horsepower Camaro ZL1 1LE didn’t get a clean start off the line. The driver compensated for wheel spin at the line with less throttle, thereby not letting the supercharged 6.2-liter LT4 V-8 give its full muscle. The Caddy just walked on by.

Hennessey Performance offers its HPE800 package for the Cadillac Escalade and GMC Yukon Denali, both with the 6.2-liter V-8. Nearly every conceivable part is removed from the engine block and replaced with high-performance parts. The crankshaft is replaced, along with the connecting rods and pistons, to create a stroked 6.8-liter engine. The cylinder heads are ported and fitted with upgraded valvetrain, and a new HPE camshaft is slid into the block.

The engine breathes through a 2.9-liter roots-style supercharger pumping out 10 psi of boost. 1.75-inch stainless steel long-tube headers dump into a performance exhaust system with dual tips.

Hennessey then upgrades the engine’s ECU to support the extra power before tuning the entire package on its in-house dyno – all while running 93-octane pump gas. The Texas-based tuning company covers its work with a one-year, 12,000-mile warranty, which is a small consolation for giving up the Escalade’s factory six-year, 70,000-mile powertrain warranty. Still, when throwing this much money at a vehicle, warranties probably aren’t a big consideration.
