Hennessey®, the Texas-based hypercar manufacturer and high-performance vehicle creator, has released a comprehensive new performance upgrade package for the GMC Yukon. Hennessey’s boost in output for late-model GM 6.2-liter V8-powered vehicles takes power from the mild 420 bhp factory level, to a wild 650 bhp – transforming the acceleration driving dynamics of the Yukon GMC.

Testing for all Hennessey® Performance models begin at the company’s headquarters in Sealy, Texas. Under the guidance of our Research and Development team, each model line is subjected to hundreds of hours of research and development. This helps guarantee that Hennessey® Performance’s 2024 GMC Yukon performance parts enhance every aspect of the vehicle while retaining complete usability and manufacturer driving modes.

After lab-based evaluation, development moves to Hennessey® Performance’s various on-site dyno bays for live assessment. The final phase of tuning has development models of the GMC Yukon test at the Pennzoil Proving Ground at Hennessey® Performance’s headquarters. This final phase is performed to evaluate the 2024 GMC Yukon tune upgrade in the real world. Even after each model line is signed-off, every customer vehicle undergoes its series of quality assurance tests, including a detailed test drive by Hennessey® Performance’s engineers.

Customer satisfaction is at the core of every Hennessey® Performance GMC Yukon performance upgrade and modifications package. Emphasizing this point, the company provides a comprehensive warranty on each 6.2-liter V8 2024 GMC Yukon upgrade to provide total peace of mind. Customers are invited to take final delivery of their new Hennessey® vehicle at the Pennzoil Proving Grounds in Sealy, Texas for the ultimate performance experience.
