The 2019 ZR1 Corvette comes with plenty of horsepower from the factory, 755 to be exact. But there’s never enough horsepower for the Texas tuner company Hennessey Performance. The company always manages to extract more out of the cars it works on and that is the case with their most powerful kit yet the ‘HPE1200‘. As the name suggests, this new upgrade package boasts a whopping 1,200 horsepower from its supercharged 6.2-liter V8 engine, which is a significant 445 hp more than the standard version. We’re not necessarily saying that the ZR1 Corvette needs more power, but if you feel it does and you own one, then hooking up with Hennessey Performance is the way to go.
