Hennessey, the renowned Texas-based hypercar manufacturer and high-performance vehicle creator, has announced a significant power upgrade for the 2025 Chevrolet Tahoe and Suburban SUVs. The new H600 performance package elevates the already capable 6.2-liter V8-powered SUVs to an impressive 625 horsepower and 633 lb-ft of torque. This comprehensive upgrade includes a Magnuson supercharger, a sport-touring exhaust system, and high-performance Brembo brakes. Complementing the added power are aesthetic and handling enhancements such as a menacingly lowered ride and distinctive Hennessey lightweight performance wheels. In a groundbreaking move, these enhanced SUVs will be available directly to customers through authorized Hennessey Chevrolet dealers across the United States, offering a seamless purchase experience with full warranty coverage and GM’s financing options.
Powertrain and Performance Details: Hennessey’s engineering team has significantly boosted the output of the 6.2-liter V8 engine in the 2025 Chevrolet Tahoe and Suburban. The H600 package features a high-performance Magnuson supercharger system, along with a high-flow intercooling system and a high-flow air induction system, all working in concert to dramatically increase power. The result is a formidable 625 bhp at 5,500 rpm and a substantial 633 lb-ft of torque at 4,200 rpm, representing an increase of over 200 horsepower and a torque gain of more than a third compared to the stock engine. A sport touring catback exhaust system not only enhances the engine’s sound but also contributes to improved performance. The package also includes a crankcase ventilation system and HPE engine management calibration to ensure optimal engine operation and reliability. These significant mechanical enhancements position the H600 Tahoe and Suburban among the most powerful SUVs available.
Chassis and Handling Upgrades: To complement the increased power, Hennessey has also addressed the handling and braking capabilities of the Tahoe and Suburban. The H600 package includes heavy-duty six-piston Brembo front brakes with eye-catching red calipers, providing significantly improved stopping power and fade resistance. The suspension is lowered by 2.5 inches at both the front and rear, giving the SUVs a more aggressive and sporty stance while potentially improving aerodynamics and handling. The H600 rides on 24-inch gloss black lightweight sport wheels, paired with Firestone Firehawk Pursuit tires, known for their optimal handling and grip, ensuring that the enhanced power can be effectively utilized.
Exterior and Interior Enhancements: The Hennessey H600 Tahoe and Suburban feature distinctive visual cues that set them apart. Hennessey exterior badging is applied to signify the performance upgrades. Inside, a serial-numbered engine plaque adds a touch of exclusivity, as production is limited to just 100 units for 2025. While the interior largely retains its Chevrolet design, the Hennessey badging serves as a constant reminder of the performance enhancements beneath the surface.
A New Era of Hennessey and Chevrolet: This collaboration marks a significant milestone, making Hennessey performance upgrades directly accessible through authorized Chevrolet dealerships. Customers can now order and purchase the H600 Tahoe and Suburban just like any other new vehicle, benefiting from comprehensive GM warranty coverage and the full range of GM finance products. Additionally, the Hennessey upgrades are backed by Hennessey’s own three-year / 36,000-mile limited warranty, providing added peace of mind. This partnership streamlines the process for customers seeking high-performance SUVs with factory support.
