The Hennessey Cadillac Escalade H600 at Bob Moore OKC

Hennessey Performance brings its expertise to a new nameplate in 2026: the Cadillac Escalade. The Texas-based company has developed the H600 upgrade package for the Escalade, turning the factory 6.2L V8 into a supercharged engine rated at 625 bhp. Bob Moore Cadillac Oklahoma City is one of the first Cadillac dealerships to enter an official Hennessey dealer partnership, meaning OKC drivers no longer have to go all the way to Texas for the Hennessey treatment. Below, we’ll break down what the H600 upgrade includes and what it means to have access to it right here in the metro. Browse our Cadillac Escalade inventory to find your starting point before diving into the upgrade details.

What is the Hennessey H600 Cadillac Escalade Upgrade?

Hennessey Performance engineers the H600 around GM’s 6.2-liter L87 EcoTec3 V8, the same block powering the standard Escalade from the factory. A high-performance twin-screw supercharger paired with an air-to-water intercooler system takes output from the factory 420 horsepower to 625 bhp and 633 lb-ft of torque. Every component in the package undergoes extensive R&D testing at Hennessey’s Pennzoil Proving Ground facility in Sealy, Texas, ensuring performance at every step. 

The H600 Cadillac package goes beyond the engine bay. Exterior and suspension upgrades include 24-inch Hennessey Performance wheels, six-piston performance brakes with red calipers, and front- and rear-suspension lowering kits. A sport touring catback exhaust system adds a more aggressive note to the Escalade’s already bold presence. Each completed vehicle receives a serial-numbered engine plaque, Hennessey exterior badging, and the brand’s 3-year, 36,000-mile warranty. Production is limited, making each H600 a rare piece of American performance engineering.

What It Means to Be a Hennessey Dealer Partner

Not every dealership can offer Hennessey-engineered vehicles. Joining the Hennessey dealer network requires a formal partnership agreement, and Bob Moore Cadillac Oklahoma City is the first Cadillac dealership in the nation to secure that relationship. When you order your Escalade through our dealership, the vehicle goes to Hennessey’s facility in Sealy, Texas, for the full H600 build before being delivered back to you. This partnership removes the complexity from the ordering process. Rather than coordinating directly with a performance shop across state lines, you work with our team from deposit to delivery. Bob Moore Cadillac Oklahoma City has long been one of the OKC metro’s premier Cadillac destinations. This partnership is a natural next step in bringing the best Cadillac experience to buyers across Oklahoma City, Norman, and Edmond.
