Sealy, Texas (January 23, 2023) – Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has released a comprehensive new performance upgrade package for the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon. Hennessey’s boost in output for vehicles with the GM 6.2-liter V8 takes power from the mild 420 bhp factory rating to a wild 650 bhp – entirely transforming the acceleration and driving dynamics of GM’s full-size SUVs.

Hennessey’s engineering team fits GM’s popular 6.2-liter V8 (L87 EcoTec3) with a robust 2.9-liter supercharger, high-flow intake system, high-flow intercooler, and a crankcase ventilation system. In addition, Chromoly pushrods are installed, and the engine management software is updated with HPE engine management calibration. Lastly, a stainless steel cat-back exhaust system (retaining stock exhaust tips) is installed to improve performance and soundtrack. The result is a dyno-proven 650 bhp and 658 lb-ft of torque.

During development, the ‘Hennessey Supercharged H650 Escalade’ – enhanced with an additional 230 horsepower – achieved 0 to 60 mph sprint in just 5.3 seconds. That was quick enough to leave the stock Cadillac Escalade, with its slower 6.1-second dash, in the rearview mirror. Likewise, the quarter mile run falls in just 13.5 seconds – a full second quicker than stock. Accompanying the increased power is a more robust full-throttle exhaust note, which perfectly complements the SUV’s enhanced performance.

Hennessey’s ‘H650’ upgrade fits a range of GM SUVs equipped with the 6.2-liter V8 – irrespective of trim level. These vehicles include the model year 2021 and onward Cadillac Escalade, Cadillac Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon, and GMC Yukon XL.

John Hennessey, company Founder and CEO: “Our team is very excited about this supercharging development for GM’s 6.2-liter V8, as it offers a huge audience of GM SUV owners the ability to bump power by an impressive 230 horsepower – that’s a 55 percent increase in power. Additionally, the improved torque increases drivability at all speeds and enhances towing. The H650 upgrade literally transforms sedate family SUVs into performance vehicles.”

Although the performance of the 6.2-liter V8 is altered, Hennessey’s engineers retain all the legendary ride and drivability of the stock SUVs, leaving suspension modes, drive modes, and all-wheel drive modes unaltered. The Texas team’s production and the testing program includes a final performance assessment on the dyno and out on the open road.

Each upgraded ‘H650’ is fitted with a serial-numbered engine plaque. In addition, all vehicles are backed by Hennessey’s comprehensive 3-year / 36,000-mile limited warranty. The total cost for the upgrade is $27,950 – excluding the base GM SUV.
