Tesla Model X preview (photos)

Tesla will offer an all-wheel-drive option for the Model X. That means an extra drive motor for the front wheels. As there are two drive motors, the torque can be changed electronically at each axle. Depending on the sensor data, the car could put 50 percent torque on the front wheels, and 100 percent torque on the rear wheels. The torque can be lowered at front and rear for slippery conditions.
