The 2019 Corvette ZR1 is the most powerful production, fastest Corvette in the world. It's a supercar that's also a great value. The 2019 Corvette Z06 is also very fast, but it's not as powerful as the ZR1. Moreso, it's still a great value, though. Which one is right for you depends on your budget and how much power you want. If you can afford it, the ZR1 is the better choice.
