If the ZR1 didn’t exist, driving enthusiasts everywhere would still be celebrating the amazingness of the latest Z06. But the ZR1 is real, and no one can ignore the 638 horsepower gorilla in the room. The ZR1 packs the most powerful engine that GM has ever put in a production car, and it’s not simply for show: how does a quarter mile time of just a bit over 11 seconds strike you? Or a top speed exceeding 200 mph? Factor in some adaptive suspension that continually adjusts to road conditions, massively sticky rubber, and a weight-saving cocktail of aluminum and carbon fiber, and you’ve got a Corvette that doesn’t just mix it up with the European exotics—it blows them away. The source of the ZR1’s superpowers is visible from the outside: peer through the clear polycarbonate hood window and you’ll see the dual intercoolers sitting atop the supercharger, feeding copious amounts of boost into the LS9 smallblock. Acceleration is savage, but it’s not as unruly as you might expect, and in the hands of a respectful driver few production cars can equal the ZR1’s sub-eight minute lap around the Nürburgring, perhaps the harshest real-world test of any car. Do you have what it takes to master the fastest GM vehicle ever?
