The tachometer displays the engine speed in thousands of revolutions per minute (rpm).

Notice: Fuel shuts off at about 6500 rpm for the base model, 7000 rpm for the Z06 model, and 6600 rpm for the ZR1 model. If the vehicle continues to be driven at the fuel shut off rpm, the engine could be damaged. Be sure to operate the vehicle below the fuel shut off rpm or reduce the vehicle's rpm quickly when the fuel shuts off.
