Back in October, Cadillac unveiled the all-new 2015 Escalade and for $72,690 this SUV can be yours. Under the hood, it comes with a 6.2-liter V8 engine that generates 420 hp and 420 lb-ft (623 Nm) of torque, bolted to a six-speed transmission. Despite these numbers, there are customers who want more from their 2015 Cadillac Escalade.
As a result, Hennessey Performance (HPE) unveiled their HPE550 Supercharged Escalade. Described as the perfect balance of attitude, performance and luxury, the HPE550 Escalade offers several upgrades. The most important upgrade is the belt-driven supercharger producing 6 psi of boost pressure that boosts the 6.2-liter V8 engine to 557 hp and 542 lb-ft (734 Nm) of torque.
Still, the extra power is nothing without reliability, so Hennessey added an air-to-water intercooler system that keeps charge temperatures low, while the recalibrated engine management computer optimizes the air/fuel ratio throughout the rev range. This upgrade costs $15,950 (installed) and has a 3 year/36,000 mile powertrain warranty.
Same tuning kit is available for other GM vehicles powered by the 6.2-liter DI V8, such as 2015 GMC Yukon Denali, 2014-2015 GMC Sierra trucks, and 2014-2015 Chevrolet Silverado trucks. Additional upgrades include the 20-inch Hennessey H10 forged monoblock wheels ($6950).
“The new 2015 Cadillac Escalade is the perfect platform for a Hennessey infusion of horsepower,” said founder and president John Hennessey. “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.”
