When the 2023 Chevrolet Corvette Z06 goes into production this summer. When the new owner finally got them, they couldn’t leave the dealership and immediately pushed the 5.5-liter dual-overhead-cam V8 to an 8,600rpm redline. Or, they shouldn’t if they care about engine longevity. Chevy recommends not to exceed 6,600 rpm for the first 500 miles (805 kilometers) as a break-in period for the powerplant.

John Elegant from that Forum Corvette Mid-Engine found this interesting detail. To make sure the owner remembers the period of the break-in. The vehicle tachometer shows a red line at 6,600 rpm. There’s nothing stopping someone from turning the engine higher, but this change in the appearance of the tach shows how seriously the company advises against it.

Motor1.com contacted Chevy to confirm that this was part of the Z06 break-in period. “It’s true. Similar to what we did with the Stingray, so it’s not exactly new,” a spokesperson for the automaker told us.

In addition to this 500-mile period, Chevy advises owners to let the car travel 1,500 miles (2,414 kilometers) before taking it out onto the track. In a forum thread, Elegant cites a recent in-depth seminar on engines as the reason for the breakdown in gears, bearings and differentials.

The LT6 V8 Z06 produces 670 horsepower (500 kilowatts) at 8,400 rpm and 460 pound-feet (623 Newton-meters) at 6,300 rpm. Chevy estimates acceleration to 60 miles per hour (96 kilometers per hour) takes 2.6 seconds. The only gearbox available is an eight-speed dual-clutch transmission.

People who want to get the most out of the Z06 should check out the Z07 Performance Pack. This includes the FE7 suspension with additional Magnetic Ride Control 4.0 calibration. There are carbon fiber wheels that shed 41 pounds (18.6 kilograms) of unsprung weight. Michelin Sport Cup 2 R ZP tires wrap it around.

Official pricing details are still not available for the Z06. Rumors suggest Chevy plans to start taking orders on March 24 and start production in May. One report puts the initial figure at $87,000.
