Hennessey Unveils 625-Horsepower Upgrade for 2025 Chevrolet Tahoe, Suburban

Hennessey Performance has introduced the H600 package for the 2025 Chevrolet Tahoe and Suburban, transforming these family SUVs into high-powered performance vehicles. Limited to just 100 units, the upgraded models feature a 6.2-liter V8 enhanced by a Magnuson supercharger, raising output to 625 horsepower and 633 lb-ft of torque—up from the stock 420 hp and 460 lb-ft. Additional modifications include a sport-touring exhaust, Brembo brakes, a 2.5-inch lowered ride height, and 24-inch gloss black wheels with performance tires. Aesthetic changes such as Hennessey badging and a serial-numbered engine plaque distinguish the models inside and out. Customers can purchase the H600 package through Hennessey or participating GM dealerships, with available financing and warranty support. These enhancements arrive as GM continues to address recalls and complaints related to the 6.2-liter V8 engine used in the base models.
