Texas-based tuner Hennessey Performance has revealed new modified versions of the 2025 Chevy Tahoe and Suburban SUVs.
The H600 package is offered for both vehicles, and brings a host of mechanical and aesthetic upgrades to the full-size Chevrolets.
The launch of the H600 Tahoe and Suburban also marks an important milestone in the three-decade history of Hennessey Performance.
The H600 Tahoe and Suburban will be the first Hennessey vehicles available direct from authorized Chevrolet dealerships. This mirrors how Hennessey has previously sold modified Ford vehicles.
Supercharging the family SUV
Hennessey’s H600 package can be applied to Tahoe and Suburban models fitted with the 6.2-liter V-8 engine.
A supercharger kit, combined with a high-flow air intake, intercooler, and cat-back exhaust system, results in 625 horsepower – 200 hp more than stock. Torque increases by more than a third, up to 633 lb-ft.
With 24-inch gloss black wheels and a suspension lowering kit, the Hennessey H600 models have a more aggressive stance. Uprated Brembo brakes with red-painted calipers are included, along with grippy Firestone Firehawk Pursuit tires.
Bespoke Hennessey badges are added to the exterior of each H600, along with a serial-numbered plaque for the upgraded V-8 engine.
Rapid transport for kids and gear
Each complete H600 comes with a three-year/36,000-mile limited warranty, providing extra peace of mind for buyers.
Hennessey will limit production of the H600 Tahoe and Suburban to 100 examples in 2025. Authorized Chevrolet dealerships are accepting orders now.
John Hennessey, company founder and CEO: “My family and I have owned countless Chevy Suburbans over the years. They’ve always been our go-to vehicles for their comfort, performance, and the space to haul kids, gear, and everything in between. That’s why we’re so excited about our 625 horsepower upgrade. It turns the Tahoe and Suburban into true driver’s SUVs that are an absolute blast behind the wheel, even when fully loaded.
“What makes this even more special is our new partnership with authorized GM dealers across the country. This makes it easier than ever for customers to access Hennessey performance directly through their local dealership.”
