Cadillac’s all-new 2015 Escalade is one impressive SUV. In addition to its svelte exterior, sumptuous cabin and assortment of tech features, the latest Escalade will tow up to 8,200 pounds and carry you and your friends in limo-like comfort. The only downside is that it’s lacking in the powertrain department. At present, the Escalade is available with just one engine: a 6.2-liter V-8 rated at 420 horsepower and 460 pound-feet of torque.

Though impressive on their own, the numbers are lacking when you compare them to the likes of the 560 horsepower in the Mercedes-Benz GL63 AMG and 510 horsepower in the Land Rover Range Rover. Fortunately for power-hungry Escalade owners, there’s Hennessey Performance.

The Texan tuner has started work on developing upgrades for the 2015 Cadillac Escalade, and the first mod, the HPE550 Supercharged, sees the SUV’s output dialed up to a healthy 557 horsepower and 542 pound-feet of torque. No performance figures are given, but it should be a whole lot quicker than stock.

The HPE550 Supercharged mod consists of supercharger running a peak 6 psi of boost. In addition to this you'll find a custom intercooler, high-flow intake and retuned ECU. The upgrade will cost you $15,950 installed, and that includes a 3 year/36,000 mile warranty on the powertrain parts. If you have additional cash to burn, Hennessey also offers a set of 20-inch forged wheels for the Escalade priced at $6,950.

And since the Escalade shares its underpinnings with several other General Motors full-size SUVs and pickups, such as the Silverado, Sierra, Suburban and Yukon, Hennessey says owners of those other vehicles can also have the HPE550 Supercharged mod installed.

“The new 2015 Cadillac Escalade is the perfect platform for a Hennessey infusion of horsepower,” Hennessey president and founder John Hennessey said in a statement. “I plan on making this our next family hauler for our five teenagers and four Labrador Retrievers.”
