(April 17, 2024) SEALY, Texas — Hennessy, the Texas-based hypercar manufacturer and high-performance vehicle creator, has released a comprehensive new performance upgrade package for the 2024 Cadillac Escalade-V. Hennessey’s engineers take the hand-built, supercharged GM 6.2-liter V8 from the standard 682 horsepower to 850 bhp at 6,200 rpm — a 25 percent rise.

The torque figure is enhanced further still, growing 31 percent to 855 lb-ft at 4,600 rpm. The Hennessey enhancements make the ‘H850 Escalade-V’ one of the quickest and highest-horsepower full-size SUVs on the market.

Hennessey's engineering team comprehensively overhauled the Escalade-V’s powertrain, with improvements including a new air induction system, a ported supercharger, high-flow cylinder heads, custom camshaft, upgraded throttle body, plus new intake and exhaust valves. In addition, following extensive R&D testing, Hennessey applies its HPE engine management calibration. H850 Escalade-V owners can also add the optional Hennessey Performance 22-inch performance wheels in either gloss black, or polished silver.

In testing, the Hennessey team pitted the three-row luxury SUV against the king of full-size performance trucks – a stock 2024 RAM TRX. The TRX boasts a factory 0-60 mph time of 4.5 seconds, and can smash a ¼ mile in around 12.3 seconds – but, the power of the H850 Escalade-V saw it outpace the TRX from the off, to finish its run several truck lengths clear.

John Hennessey, company founder and CEO: "Extreme-performance SUVs are one of my favorite types of vehicle to drive – their sleeper status is such a great contrast to their supercar-like performance! Our 850-horsepower version of the Escalade-V brings heaps of performance to this luxury full-size SUV, doing the GM supercharged V8 engine justice. We’re only making 100 of these H850 models, so they’re sure to be exclusive."

Hennessey ensures total customer peace of mind by supplying each H850 Escalade-V with a 3-year / 36,000-mile limited warranty. Also, despite all the enhancements to the 6.2-liter V8, Hennessey's engineers retain all the legendary ride and drivability of the stock SUV, with all suspension and drive modes unaltered. The Texas team's production and testing program includes a final performance assessment on an AWD dyno and drivability testing on Hennessey’s private test track, the Pennzoil Proving Ground.
