The Corvette C7 ZR1 was unveiled at the 2017 Dubai Motor Show for the 2019 model year. The ZR1 is heavily based on the Z06 platform with many noticeable changes, including the all new 6.2 L pushrod LT5 V8 engine equipped with a 2.6 L Eaton supercharger that is 52% larger than that of the Z06 along with a new fuel injection system. The new engine produces 755 PS (745 hp) and 715 N·m (527 lb·ft) of torque. The ZR1 also includes an improved engine cooling system with large cooling vents in the front bumpers, vents on the bonnet and a larger intercooler. The cooling system also adds 4 more radiators bringing the total count to 13. Due to the large supercharger and intercooler, an opening is made in the bonnet but is concealed by making the intercooler cover in such a way that it looks like a part of the bonnet. The ZR1's aero package has been developed in collaboration with the Corvette racing team in wind tunnels which includes a large rear wing bolted directly on the chassis, a front splitter and a new underbody spoiler to balance drag. A fixed wing was added after the engineers at Corvette racing team discovered that an active rear wing serves no more than an aesthetic purpose. Due to the added aero elements, the ZR1 produces 70% (950lbs of downforce at top speed) more downforce than the Z06. Other changes include an active exhaust system and an upgraded crankshaft, all of which help propel the car to a projected top speed in excess of 210 mph (338 km/h). The optional aero packages available for the ZR1 are the Z07 performance package which adds a higher and a two way adjustable fixed rear wing which generates 60% more downforce than the Z06 but also reduces top speed due to aerodynamic drag, and the ZTK performance package which also adds a new front splitter, Michelin Pilot Sport Cup 2 tires instead of the standard Michelin Super Sport tires and specific chassis and magnetic ride control settings for better cornering. Besides the extensive use of carbon fiber, the ZR1 is heavier than the Z06 at 3560lbs due to added fluids for the cooling system. The ZR1 is available with a 7-speed Tremec TR-6070 manual transmission with rev-matching technology or an 8-speed GM 8L90 automatic transmission with paddle shifters which are the same as those found in the Z06. The ZR1 comes with larger tires and wheels, carbon ceramic brakes, double wishbone suspension system and magnetic ride control system as standard with optional brake caliper colors and wheels. The interior includes Nappa leather upholstery, heated seats, carbon fiber rimmed steering wheel and Bose sound system as standard with a variety of performance and comfort options available. The ZR1 will be available for sale in the spring of 2018 with a price tag starting from $120,000.
