More power for America’s sports car.
The new, seventh-generation Chevrolet Corvette Stingray blew us all away at the beginning of this year. It finally addressed many of the issues that had been plagued the C6-generation model and put itself at the forefront of the international sports car market. Now the team at Hennessey Performance is looking to inject even more power into the Corvette Stingray with their new HPE500 and HPE600 upgrade programs.
The first upgrade program for the new C7 Corvette Stingray is the HPE500 from Hennessey Performance. The kit is designed specifically for the new 6.2-liter LT1 V-8 engine that pumps out 455 bhp from the factory. Starting things off are a set of stainless steel long-tube headers, high-flow catalytic converters, and new midpipes that connect to the factory dual-mode performance rear exhaust with valve control. After a quick HPE engine management calibration and some dynometer testing, the Chevrolet Corvette Stingray churns out an impressive 507 bhp at 6,300 RPM and 518 lb-ft. at 3,800 RPM, rocketing America’s sports car to 60 mph in 3.8 seconds. This also allows the Corvette to shoot through the quarter-mile in 11.7 seconds at 122 mph.
For customers that want even more power, there’s the more exclusive HPE600 Corvette Stingray. The HPE600 includes all of the fun go-fast goodies that were featured on the HPE500 and adds a few more for good measure. A new HPE-spec hydraulic roller camshaft and ported and polished cylinder heads for better airflow help to produce even more power for the naturally aspirated engine. Then a specially-designed HPE tune that optimizes fuel and spark with 93-octane fuel is installed and results in a total of 603 bhp at 6,500 RPM and 535 lb-ft. at 4,200 RPM. The added power enables the C7 Corvette Stingray to reach 60 mph in 3.5 seconds and go through the quarter-mile in 11.3 seconds at 127 mph.
A number of upgrades come standard on the HPE500 and HPE600 upgrade programs from Hennessey. Each car comes with a limited-edition dashboard and engine plaque, premium floor mats, carbon fiber door sills, and exterior badging. As an option, customers can also order the Hennessey H10 monoblock forged wheels with ten-spoke design that reduce weight by up to 19 lbs. Other options include Brembo carbon ceramic brakes, Hennessey CarbonAero body kit, Michelin Pilot Super Sport tires, Penske adjustable suspension, and interior refinements.
Both of the new Hennessey Performance upgrades are currently available for the C7 Corvette Stingray and come standard with a three-year/36,000-mile warranty. The HPE500 costs $4,995 installed and is limited to 500 units while the HPE600 is priced at $10,950 installed and is limited to just 100 units for 2013.
