Abstract: A multiple vehicle launch system for an automobile vehicle includes a vehicle-to-infrastructure (V2I) communication system to track performance data of a vehicle launch event of a first and a second automobile vehicle and coordinate getting the first and second automobile vehicles to a driving area to conduct the vehicle launch event. A vehicle-to-vehicle (V2V) communication system provides direct communication between the first and second automobile vehicles at the driving area to coordinate a simultaneous launch of the first and second automobile vehicles. A driver enable setting permits a first operator to elect to conduct the vehicle launch event. A readiness identifier is actuated in the first and second automobile vehicles and the vehicle launch event is initiated after the first operator and a second operator of the second automobile vehicle signify readiness by actuating the readiness identifier. An autonomous launch may also be conducted.

Abstract: A method and controller for controlling an electronically controlled transmission in a vehicle propulsion system of a vehicle. The method includes disengaging a clutch in the transmission to prevent a power flow through the transmission in response to an upshift paddle selector and a downshift paddle selector both being actuated together for a first predetermined time period, and changing a ratio of the transmission in response to an actuation of one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent a power flow through the transmission.
