Here at GM Authority, we are huge advocates of performance, except for when we aren’t. But when it comes to Corvettes and quarter-mile times, we’re all about it times infinity. So when we found a video titled “World’s Fastest Corvette ZR1”, our eyebrows raised, and we scoffed at such a claim. But with a power rating of 1,500 hp, and a quarter-mile time of just 9.68 seconds, it could very well be the fastest road-legal ZR1 that we know of. Oh, and it also hit 236 mph at the Texas Mile. That’s what happens when you twin turbo a 440 cubic inch V8.
