The 2025 Zr1’s new twin-turbo, 5.5L flat-plane-crank LT7 engine makes more power than two LS7 engines. Top speed is over 215 mph.
Today, GM took the covers off the most powerful and fastest Corvette of all time, the 2025 ZR1. We’ll have a lot more coverage to offer over the next few days. But instead of writing up a mix of facts and opinions, this post is designed to give you all of the facts and none of the fluff or PR razzle-dazzle, outside of a few fun facts. At this time, we’re still waiting to hear about official pricing and whether or not there is going to be a future, top-of-the-line ZORA model. For now, at least, the King of the Hill is back for 2025 and better than ever along with the “most powerful V8 ever produced in America from an auto manufacturer.”
