Hennessey Supercharges 2015 Cadillac Escalade to Create HPE550

Texas-based tuner Hennessey Performance is known for its wild, high-horsepower creations that take already quick production cars like the SRT Viper and make them even quicker. The company’s latest creation, the HPE550, is based on the 2015 Cadillac Escalade luxury SUV and is said to target other high-performance luxury SUVs like the Mercedes-Benz GL63 AMG and the Range Rover Sport Supercharged.

To create the HPE550, Hennessey takes the Cadillac Escalade’s standard direct-injection, 6.2-liter V-8 engine and bolts on a supercharger and intercooler that make for 6 psi of boost. There’s also a new engine management computer to deal with the extra power, which totals 557 hp and 542 lb-ft of torque—that’s 137 hp and 82 lb-ft more than stock. All of this extra grunt will cost a whopping $15,950, including installation, although it does come with a 3-year/36,000-mile warranty.

All HPE550 models gain special Hennessey badging, embroidered floormats, and a serial-number plaque on the dashboard and the engine. Hennessey is also offering other upgrades for the 2015 Cadillac Escalade to go along with the supercharger kit, like a set of forged monoblock 20-inch wheels for an extra $6950.

If the Cadillac Escalade is too flashy for your tastes, Hennessey will also offer the HPE550 upgrade for any other GM trucks and SUVs equipped with the same 6.2-liter V-8 engine, including the GMC Yukon and Yukon XL, the Chevrolet Silverado, and the GMC Sierra.
