The results are simply spectacular: 1,064bhp arrives at 7,000rpm with 828lb ft of torque landing at 6,000rpm. The ZR1 has a dry weight of 1,665kg in coupe form (a convertible is also available weighing 1,705kg). That peak power figure is more than the output of two LS7 engines combined.
All this performance is sent to the rear wheels(!) via a modified version of the Corvette’s eight-speed dual-clutch transmission, albeit with refinements made to the final drive ratio.
Adaptive Magnetic Ride underpins the chassis, with a double wishbone setup using forged upper and cast lower aluminium wishbones at the front and rear. A rear anti-roll bar is fitted, too.
The optional ZTK package includes stiffer springs and a higher downforce rear wing, to accompany the ZR1’s standard carbon fibre battle dress of splitters, brake cooling ducts and aero-winglets. The ZTK package also replaces the standard Michelin Pilot Sport 4 S tyre with a Sport Cup 2 R for the staggered 20 and 21-inch, front and rear, wheels. Carbon wheels are an option and reduce unsprung mass by 19kg.
Carbon-ceramic brakes with 400mm front and 390mm rear discs are standard, with six and four-piston calipers front and rear. Naturally, the ZR1 requires some aerodynamic support and all the carbon-flicks, splitters and wings combine to generate 544kg for downforce at 215mph, the car’s maximum speed.
