Hennessey®, the Texas-based hypercar manufacturer and high-performance vehicle creator, has released a comprehensive new performance upgrade package for the Chevrolet Suburban. 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 Chevrolet Suburban.
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 2023 Chevrolet Suburban 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 Chevrolet Suburban test at the Pennzoil Proving Ground at Hennessey® Performance’s headquarters. This final phase is performed to evaluate the 2023 Chevrolet Suburban 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 Chevrolet Suburban performance upgrade and modifications package. Emphasizing this point, the company provides a comprehensive warranty on each 6.2-liter V8 2023 Chevrolet Suburban upgrade to provide total peace of mind.
