The 1,255-HP Showdown! Chevrolet Corvette ZR1 vs. Porsche 911 GT3

Edmunds’ Alistair Weaver and Carlos Lago test and compare the 2019 Chevrolet Corvette ZR1 and the 2018 Porsche 911 GT3. For similar money, these two super sports cars deliver massive driving thrills and motorsports technology for the street. The ZR1 is the highest-performing Corvette available, with 755 horsepower and a wild optional track package that gives it huge sticky tires and an enormous wing. The GT3 may not have the power bragging rights, but it represents a purity of focus. It’s built alongside real race cars, and its 4.0-liter engine revs to a beautiful 9,000 rpm. Which one is the most fun on the road and at the racetrack? Watch to find out!
