The C7 Corvette ZR1 stands as the pinnacle of front-engine Corvette performance—a final chapter of raw American power before the transition to mid-engine. Straight from the factory, it delivers a staggering 755 horsepower from its supercharged 6.2L LT5 V8, making it the most powerful production Corvette ever built. With its aggressive aero, track-tuned suspension, and menacing presence, the ZR1 is a modern muscle icon. But for those who demand even more—more speed, more sound, more adrenaline—Hennessey Performance offers the HPE1000 upgrade, transforming the already-potent ZR1 into a supercar slayer. The HPE1000 package boosts output to over 1,000 horsepower and 966 lb-ft of torque, thanks to a high-flow supercharger system, ported cylinder heads, a custom camshaft, upgraded fuel system, stainless-steel headers, and Hennessey’s expert engine calibration. This isn’t just about power—it’s about delivering relentless acceleration with reliability you can trust. Whether you’re chasing quarter-mile records or carving corners at the track, the HPE1000 C7 ZR1 delivers a visceral driving experience that few cars on the planet can match. With exclusive Hennessey badging, serial-numbered plaques, and dyno-proven results, this build is the ultimate send-off for the front-engine Corvette legacy.
