With 670 horsepower and 460 pound-feet of torque, the mid-engine 2023 Corvette Z06 is an absolute screamer of a performance car. However, before you send that naturally aspirated V8 up to its 8,600-rpm redline, the 2023 Corvette Z06 requires a brief engine break-in, as detailed in the following video.
Clocking in at 4 minutes, 43 seconds, the video is hosted by Chevy MyWay Product Specialist Billy Konsoer, who leads the viewer through the Corvette Z06 engine break-in process and why it’s important. At it’s core, the break-in process requires that the driver to vary vehicle speeds and engine rpms, and observe a 500-mile break-in period for street driving, as well as a 1,500-mile break-in process before unleashing the new Z06 on the race track. Further guidance is included in the Corvette Z06 owner’s manual.
According to Assistant Global Chief Engineer, Small Block V8 Engines, Dustin Gardner, this break-in process helps to protect vital engine components, including the running surfaces, or the bearings.
“You need to give the bearings that first critical five hundred miles,” Gardner says. “So there’s actually some material in the bearing that moves around. The top layer of the bearing is about 20 microns thick; human hair is about 70, so we’re talking fractions of a human hair.”
As the engine operates, the top layer of the bearing will adapt to the surface and provide the clearance needed.
Notably, the Corvette Z06’s eight-speed dual-clutch transmission also requires a break-in period, and as such, the onboard system reduces engine power for the first five hundred miles and first two gears.
The video also briefly looks at GM’s dyno testing procedure for the Corvette Z06 engine, as well as the type of engine oil used.

As a reminder, the 2023 Corvette Z06 features the atmospheric 5.5L V8 LT6 gasoline engine for motivation, while under the skin, the sports car rides on the GM Y2 platform. Production takes place exclusively at the GM Bowling Green plant in Kentucky.
