We wondered which electric truck/SUV would be the first to break into mainstream use. But we hadn’t really thought about the new Tesla Model Y, which, we totally forgot, includes an “Off-Road Assist” mode. In addition to allowing the wheels to spin, Off-Road Assist balances the torque between the front and rear motors to optimize traction. Off-Road Assist improves traction on rough and soft surfaces where one side of the vehicle may lose traction while the other side still has traction. When Off-Road Assist is on, the accelerator pedal provides more gradual torque, which is useful for crawling at low speeds (for example, over rocky surfaces).
