Hennessey Planning 1,200-HP Corvette ZR-1 Because Of Course It Would


Because 755 hp isn't good enough in Texas.

It’s only been a couple of weeks since Chevrolet unveiled its ultimate front-engined Corvette, the 755 hp ZR-1. Now, there are some people, who may or may not be somewhat mental, who feel 755 ponies isn’t enough. They often come from Texas. How convenient then that Texas-based Hennessey Performance has announced plans for not one, but three upgrade packages for the ZR-1. The first is the HPE850, followed by the HPE1000 and HPE1200. Each one, obviously, is more powerful than the previous.

However, even the least powerful HPE850 will pack quite a punch. Along with an output upgrade to 850 hp (an extra 95 ponies over the stock version), buyers will receive a modified lower pulley, high-flow cylinder heads, upgraded valve springs, intake and exhaust vales and new pushrods and lifters. In order for the HPE1000 version achieve its 1,000 hp and 966 lb-ft, a new supercharger is required. It also features most of the same equipment upgrades as the HPE850. As for the granddaddy of them all, the HPE1200, Hennessey went all out. Under the hood, the 6.0-liter supercharged V8 has become a supercharged 7.0-liter V8. Power is up to 1,200 hp and 1,066 lb-ft of torque.

Expect a 0-60 mph time of just 2.2 seconds, a quarter-mile time of 9.2 seconds at 147 mph, and a top speed in excess of 230 mph. The HPE850 and HPE1000 packages each come with a 2-year/24,000-mile warranty while the HPE1200 has a 1-year/12,000-mile. The Corvette ZR-1’s engineering team believes they created the ideal high-performance Corvette. Hennessey Performance clearly thinks otherwise. Expect Hennessey to roll out its Corvette ZR-1 upgrade packages sometime next year. Pricing will also be announced closer to launch date.
