Abstract: A vehicle system for an electrified vehicle that implements a race preparation mode for preparing the electrified vehicle for a race event is provided. The vehicle system includes a motor, a battery system, an instrument panel cluster and a controller. The controller initiates the race preparation mode based on user selection of the race preparation mode. The controller determines whether a drag race mode is selected and determines whether a measured temperature of the battery system is below a warm temperature threshold. The temperature of the battery system is elevated based on the measured temperature being below the warm temperature threshold. The controller determines whether a track mode is selected and determines whether a measured temperature of the battery system is above a cold temperature threshold. The temperature of the battery system is reduced based on the measured temperature being above the cold temperature threshold.

Speed differential is enabled between the left and right rear wheels and the left and right front wheels. Based on a direction of the steering wheel, a desired torque input is determined to one of the left and right rear wheels.

Abstract: An electrified powertrain for an electrified vehicle includes a first electric drive module (EDM), a second EDM and a controller. The first EDM includes a first electric motor. A first gearbox transfers first drive torque from the first EDM to drive first drive wheels. The second EDM includes a second electric motor. A second gearbox transfers second drive torque from the second EDM to drive second drive wheels. The second gearbox has first and second clutches that provide two distinct gear ratios. The controller operates the electrified powertrain in (i) a normal drive mode wherein drive torque is commanded from the first and second electric motors, and a (ii) neutral drive mode wherein the clutches are commanded to an open position whereby the second drive torque is disconnected from the second drive wheels and drive torque is commanded from only the first EDM.

Abstract: A vehicle system for a vehicle that implements a launch control mode to vehicle wheels for creating a launch control includes a motor, an instrument panel and a controller. The motor provides drive torque to at least one wheel of the vehicle wheels for propelling the vehicle. The instrument panel cluster is configured to display a user interface menu that includes a user selectable launch control mode. The controller initiates a launch control mode based on user selection of the launch control mode. The controller determines whether vehicle conditions are satisfied and receives a launch intensity selected at the user interface menu. The controller enables torque to be delivered from the motor to all drive wheels based on the launch intensity. Wheel speeds are monitored and wheel slip is determined. Torque is sent to select wheels based on the determined wheel slip.
