"Driver mode choices have been expanded from four to six, allowing drivers to tweak the feel of their Corvettes to their personal preference," Chevy said.
"The familiar Weather, Tour, Sport and Track modes remain, and there are two new modes: MyMode, a configurable setting for preferred driving style that can remain between key cycles; and Z mode, named after the famed Z06, ZR1 and Z51 Corvette performance packages."
"Z mode is activated through a 'Z' button on the steering wheel. This is a single-use mode that takes MyMode configurations one step further, allowing drivers to adjust the engine and transmission, as well."
