2019 Chevrolet Corvette ZR1, Hennessey Performance has announced three upcoming packages for the supercar, one of which promises to deliver 1,200 hp.
The entry-level kit, dubbed the HPE850 upgrade, will see the LT5 6.2-liter supercharged V8 engine equipped with a lower pulley upgrade, high flow cylinder heads, upgraded valve springs, intakes and exhaust valves, new air induction system, stainless steel heads, stainless steel midpipes, custom camshafts, and high-flow catalytic converters.
With these mechanical upgrades working alongside software tweaks, the upgrade will lift power from 750 hp to 850 hp, resulting in a 0-60 mph (96 km/h) time of roughly 2.6 seconds and a 10.3 second quarter mile at 136 mph.
Next in the range will be the HPE1000 package. Utilizing many similar upgrades to the HPE850 package but some add-ons, including a new supercharger and intercooler, the car should reach 60 mph in 2.5 seconds, run the quarter mile in 9.7 seconds at 147 mph and exceed 220 mph, all thanks to 1000 hp and 966 lb-ft of torque.
Last but not least will be the HPE1200. Pumping out 1200 hp at 6,400 rpm and 1066 lb-ft of torque, it’ll achieve 0-60 mph in 2.2 seconds, the quarter mile in 9.2 seconds and potentially reach more than 230 mph.
No pricing details have been announced but Hennessey says it will offer 2-year, 24,000-mile warranties for the HPE850 and HPE1000 packages and a 1 year, 12-mile warranty for the HPE1200.
