The power behind this performance capability is the new LS9, a supercharged and intercooled, 6.2-liter version of the famed small-block V-8 that is assembled by hand at GM’s Performance Build Center in Michigan. The LS9 uses a new, sixth-generation Eaton supercharger that expands the effectiveness of the compressor, helping give the engine terrific low-end torque and high-rpm power. The tremendous power boost of the “blower” allowed the engineers to spec a “smaller” cam than we use on the Z06’s LS7 engine, giving the ZR1 exceptional drivability. You can drive this car to work every day and it doesn’t beat you up, yet you can take it to a racetrack on the weekend and mop the floor with the competition.

Final power numbers for the LS9 are 620 horsepower, and nearly 600 lb.-ft. of torque. The engine is backed by a Tremec TR6060 six-speed manual that uses a dual-disc clutch that, again, enhances the overall driving feel with a smooth, easy pedal effort. I’d be remiss if I didn’t mention the carbon-ceramic brakes and second-generation magnetic ride control that are standard, too.

On the outside, the ZR1 stands out with unique, larger wheels and tires, a distinctive rear spoiler and unique front fenders with dual-split vents. But admirers and wary competitors will certainly know the car from its windowed hood and exposed-weave carbon fiber parts. The hood window provides a look at the top of the engine’s intercooler and the exposed-weave carbon-fiber parts are found on the roof, rocker moldings and front splitter. Carbon fiber was previously used on the Corvette, but GM wanted to show it off on the ZR1 and a new clear coat that blocks ultra-violet rays finally allowed them to do it.
