The 2015 Cadillac Escalade may produce a robust 420 horsepower and 460 lb-ft of torque from its standard 6.2-liter V8 engine, but for some people, that just isn’t enough. People like John Hennessey, whose tuning company, Hennessey Performance Engineering, is famous all over the world for making fast things go faster.
Hennessey has added a high-flow belt-driven supercharger system, a new intercooler and a remapped software system to the new Escalade, bringing total output to 557 horsepower and 542 lb-ft of torque. This represents a 32 percent gain in power and an 18 percent gain in torque compared to stock. Also available with the kit are a set of sporty lightweight Hennessey H10 forged monoblock wheels, which are able to accommodate the Escalade’s stock tires.
“The new 2015 Cadillac Escalade is the perfect platform for a Hennessey infusion of horsepower,” HPE founder and president John Hennessey said in a statement. “It’s luxurious, spacious and cries out for personalization and more performance. I plan on making this our next family hauler for our five teenagers and four Labrador Retrievers.”
The HPE supercharger kit for the Escalade is available on all General Motors trucks and SUVs equipped with the 6.2-liter V8 engine. These include the 2015 GMC Yukon Denali, 2014-2015 GMC Sierra trucks, and 2014-2015 Chevrolet Silverado trucks.
The HPE 550 supercharger kit is offered with a 3 year/36,000 mile powertrain warranty. It will cost you $15,950 fully installed, but the pictured monoblock wheels will bump the price up by another $6950. If you’re hoping for more power you might want to hold out, though. Hennessey is bound to squeeze every last bit of performance out of the Escalade they can, after all, they managed to get the outgoing model to produce 1000 horsepower and do 0-60 in 3.4 seconds.
