    Abstract: A vehicle includes a vehicle structure that extends along a longitudinal axis. An engine includes a crankshaft that defines a crank axis disposed substantially transverse to the longitudinal axis. A transmission includes an output shaft that defines a transmission output axis substantially parallel with the crank axis. The transmission output axis is disposed nearer the forward end of the vehicle structure than the crank axis. The crank axis is disposed vertically above the transmission output axis a distance of about 140 mm. The engine includes at least one cylinder bore that defines a bore axis disposed perpendicular to and may intersect the crank axis. The bore axis may be angled toward the forward end of the vehicle structure to define an angle between the bore axis and a vertical plane. The angle between the bore axis and the vertical plane may be about 18°.

    Abstract: A transmission is provided having an input member, an output member, a plurality of planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. One of the plurality of torque transmitting devices is an integrated friction launch clutch. A disconnect clutch is in series relationship with the launch clutch and is configured to disconnect the launch clutch from at least one of the plurality of planetary gear sets. The torque transmitting devices include clutches and brakes actuatable in combinations of two to establish at least ten forward gear ratios and one reverse gear ratio.

    Abstract: A powertrain includes an engine, a transmission, a pump for providing pressurized hydraulic fluid and a launch clutch connected between the engine and the transmission for coupling the engine to the transmission when the launch clutch is in an engaged condition and for decoupling the engine from the transmission when the launch clutch is in a disengaged condition. A device is rotationally coupled to the engine and to the pump. The device is translatable along an axis between a first position and a second position. The device moves the launch clutch to the engaged condition when in the first position and does not move the launch clutch to the engaged condition when in the second position. A piston in communication with the pressurized hydraulic fluid provided by the pump is configured to translate the device along the axis between at least one of the first and second positions.
