Tesla uses a 1-speed automatic transmission, meaning they only have one gear when it comes to shifting as they don’t need more than that. This is because electric motors generate 100 percent of their torque (required for acceleration) at very low speeds, while internal combustion engines only generate torque in a small range of speeds.
On a practical level, this means combustion engines use the varying gear ratios in the transmission to accelerate the vehicle. With electric motors, the speed increases, torque decreases, and power increases, giving the Tesla all the power it needs for excellent acceleration, which is demonstrated by the Model-3 going from zero to 60 mph in 3.2 seconds.
