When Hennessey takes delivery of a new vehicle, you know it’s only a matter of time before they have a package available where the latest and greatest supercar is pushing 1,000 or more horsepower. Over the last few months, the aftermarket tuning company has taken delivery of several potent supercars such as the Ford GT. Hennessey is expanding its supercar portfolio with the 2019 Chevy Corvette ZR1 and its massive rear wing. In a new video, several Hennessey employees get behind the wheel to record their first driving impressions – and it seems like everyone is quite happy. 

The 2019 Corvette ZR1 produces 755 horsepower and 715 pound-feet of torque from its supercharged LT5 V8 engine, and it seems the team at Hennessey is quite impressed with what the ZR1 brings to the table. Reactions ranged from “For a stock vehicle this is really impressive” to “Not too bad.” One honest employee said, “I’d lose my license in about a week.” It probably wouldn’t take that long. 

Head over to Hennessy’s website, and you’ll notice the company already offers three packages – HPE850, HPE1000, and HPE1200. The numbers correlate to the ZR1’s new horsepower rating. So the HPE850 produces 850 hp and 715 lb-ft of torque. The HPE1000 package makes 1000 hp and 966 lb-ft of torque. The HPE1200 makes an absurd 1,200 hp and 1,066 lb-ft of torque. Hennessey increases the power through various modifications depending on the pack and desired output. 

The 1,200 hp is achieved by adding a high-flow supercharger system, a 7.0-liter engine upgrade, custom aluminum pistons, forged steel connecting rods, and several other modifications that add strength to the high-powered engine. The Corvette ZR1 HPE1200 can hit 60 miles per hour from a standstill in 2.2 seconds and complete the quarter-mile in 9.2 seconds at 147 mph. Top speed is more than 230 miles per hour. It’s, uh, fast. 

The video is a reminder that even a modest 755 hp can put a smile on the face of Hennessey employees who likely experience obscene amounts of horsepower.
