came up with an unexpected nugget of EV news: Lexus is considering building an EV at some point in the future with a manual transmission. The catch? It won’t be a real manual transmission if it happens. Instead, it’ll be a simulated shift lever and a simulated clutch pedal.
Though, there is one problem. Electric motors do not generate the same torque from zero to maximum RPM. They all put out full power until a certain speed; then their torque begins gradually decreasing. Efficiency also varies speeds that the motor is capable of going. The sweet spot, where they are most efficient, ranges around ⅓ to ½ power at 30–40 MPH .
The trouble was that Tesla couldn’t manage to create a multi-speed gearbox able to bear the torque of an electric motor. It was already struggling with cost delays, and had no choice but to give up on the multiple speed transmission. However, work on the “Whitestar” prototype for the Model S gave it another idea: by improving power electronics, it could stuff more electrons into it to make an even longer torque curve .
