When Chevrolet unveiled the 2019 Chevy Corvette ZR1 at the 2017 Dubai Motor Show, it described the super coupe as its most powerful and quickest production Corvette. With up to 755 hp (563 kW) of max output And 715 lb.-ft. (969 Nm) of peak torque available from its supercharged 6.2-liter V8 engine (LT5), the new Corvette ZR1 is a serious supercar for the track.
But now, Hennessey has come up with three power packages that essentially hike the power output of the 2019 Corvette ZR1. These power packages would appeal to ZR1 owners who want to squeeze the potential of their already high-performance super coupe. Each of the three power packages represents a new level of performance for the 2019 Corvette ZR1.
For instance, the HPE850 ups the power level of the 2019 Corvette ZR1 to 850 hp (634 kW) of max output and 715 lb.-ft. (969 Nm). This allows the Hennessey Corvette ZR1 HPE850 to accelerate from zero to 60 mph (96 km/h) in just 2.6 seconds, or 0.1 second quicker than the stock super coupe. This was achieve by employing high-flow cylinder heads, a high-flow air induction system and upgraded valve springs as well as a Hennessey lower pulley upgrade.
For those who are looking for more, they could avail of the HPE1000 package. The Hennessey Corvette ZR1 HPE1000, as its moniker indicates, delivers 1,000 hp (745 kW) of max output and 966 lb.-ft. (1,309 Nm) of peak torque. Because of the increased levels of output and torque, the Hennessey Corvette ZR1 HPE1000 is quicker than the standard version. This package endows the Hennessey Corvette ZR1 HPE1000 with the ability to sprint from nil to 60 mph (96 km/h) in just 2.5 seconds and reach a top speed of 220 mph (354 km/h).
Just when people think that 1,000 hp is insane, they may reconsider that thought when they learn that Hennessey is offering a 1,200-hp power boost package – the HPE1200. Aside from delivering 1,200 hp of output, the Hennessey Corvette ZR1 HPE1200 also offers up to 1,066 lb.-ft. (1,445 Nm) of torque. This power package sends the Hennessey Corvette ZR1 HPE1200 sprinting from a standstill to 60 mph in only 2.2 seconds as well as reach a top speed of 230 mph (370 km/h). To achieve this level of power, several upgrades were made to the LT5 engine including a high-flow supercharger system, HPE management calibration and custom aluminum pistons as well as stainless steel headers and mid pipes.
While these power packages are really enticing, Hennessey didn’t say how much each upgrade costs. For a discerning client, a power upgrade could mean a significant addition to the price of stock Corvette ZR1, which has a coupe version that’s priced from $119,995. The ZR1 convertible, meanwhile, has a base price of $123,995.
