Hennessey to Supercharge 2015 Escalade to 557HP

“Fast, versatile and proudly American.”

As the mammoth Cadillac Escalade inches closer to showrooms, GM is working to convince buyers that the former pinnacle of cool is still relevant in today’s thriftier auto market. From its luxurious interior to improved performance, the Escalade is better than outgoing models in just about every measure. But for Texas-based tuner Hennessey, 420 horsepower just isn't enough. The company is now offering a supercharger upgrade for the Escalade, and it is indeed quite the upgrade.

The HPE550 package supercharges the stock 6.2-liter V8 engine with six psi of boost pressure. Along with an air-to-water intercooler system, an ECU remap and new gaskets, output rises to 557 hp and 542 lb-ft of torque. It also comes with a 3-year or 36,000 mile powertrain warranty. In addition to the Escalade’s $71,695 to $92,840 price range, the package will cost $15,950, before adding $6,950 for 20-inch wheels. That brings the Caddy’s price tag well into Range Rover and Mercedes GL stratum. But then again, neither of those can offer a car that’s “proudly American,” as Hennessey flaunts on its website.
