Jumps the car into a personalized track mode.

The C8 will have expanded driving modes, with six presets compared to the current car's four: Weather, Tour, Sport, Track, plus an individually-configurable MyMode and the new Z Mode. That final mode is named for the Z51, Z06 and ZR1 performance models known to Corvette aficionados, and offers further individualized configuring of chassis, engine and transmission parameters, accessible through a new "Z" button on the steering wheel. Performance Traction Management, the advanced multi-mode traction and stability control system with five levels of increasingly-lax intervention for track driving, is once again available.
