Hennessey has tuned the fastest, most powerful road-going Corvette to date, the 2019 C7 ZR1; changing it into something wilder than before. But that’s what the Venom GT creator is always good at, making fast cars go faster. Now if you’re a performance lover and choose the ZR1 as your car, you probably think that 700 hp is enough of an entertainment. That, though, until you know that the American tuning house can give the car more than 1000 hp.
The Corvette ZR1 normally makes 755 hp and 715 lb-ft of torque through a supercharged 6.2-liter V8 engine lying under its bonnet. That output is enough to send the car from zero to 60 mph in 2.9 seconds, before hitting a top speed of 212 mph.
With the usual mindset, Hennessey believes the sports car deserves more than those figures. So it took upon itself to make an even bigger output for the coupe. The tuner utilized its HPE 1200 performance package which includes a number of upgrades compatible with the ZR1. As the name suggests, the package bumps the car’s output to 1,200 hp at the crankshaft and 1,066 lb-ft of torque at 4,000 rpm.
The increased power is partly thanks to a ported supercharger that takes the place of the stock unit, in addition to ported cylinder heads, high-flow catalytic converters, stainless steel mid-pipes, and long-tube stainless steel headers. The exhaust system is also totally updated, enabling the car to sing a beautiful, air-piercing soundtrack usually only heard on the race track.
Aside from sounding great, the ZR1 shows quite a lot of wriggle during this clip. Yes, it puts out at best 1,139 hp and 994 lb-ft of torque on the dyno, but it’s very grumpy as it tries to break free from the restraints. It seems like the beast can accelerate quickly, too. In fact, it takes only 6 seconds to speed up from 80 mph to 175 mph, which is impressively fast.
So, are you now interested in getting the HPE 1200? Just prepare enough cash because the package isn’t sold affordably. Hennessey is pegging it at $59,950, excluding the $123,000 Corvette ZR1. On the whole, it’ll set you back at least $182,950, but that’s a reasonable price given the big power you’ll play with.
