Electrified vehicle performance mode with intentional wheel spin for tire heating

A system comprising:

• a first electric machine configured to provide propulsive torque to wheels of a first axle;
• a second electric machine configured to provide propulsive torque to wheels of a second axle;
• an electric energy store configured to power the first and second electric machines;
• a braking system configured to apply a braking torque to the wheels of the first and second axles;
• a human-machine interface (HMI) configured to receive input from, and provide output to, a vehicle operator;
• and
• a controller in communication with the first and second electric machines, the braking system, and the HMI, the controller programmed to, in response to activation of a tire heating selection via the HMI and concurrent depression of an accelerator pedal to a position exceeding a first threshold and a brake pedal to a position exceeding a second threshold, wherein the first threshold is higher than the second threshold:
• command the braking system to apply braking torque to the wheels of the first axle while commanding the second electric machine to apply driving torque to the wheels of the second axle to intentionally spin the wheels of the second axle at a predetermined maximum speed during a first time period;
• and
• after expiration of the first time period, command the braking system to release braking torque to the wheels of the first axle and apply braking torque to the wheels of the second axle while commanding the first electric machine to apply driving torque to wheels of the first axle to intentionally spin the wheels of the first axle at a predetermined maximum speed during a second time period.
