> Electric motors don’t need manual (or indeed, any) transmissions because they have a basically-flat torque curve across their entire RPM range.

I would argue that for an EV that is not designed to be a sports car (ie, a Model 3), you are correct.

But one that is being designed to not just have power off the line, but also at the top end, will probably need a transmission.

I do wonder if the top speed of my Model 3 Performance is due to simply not having enough power to overcome drag, or if the motors are reaching the end of their RPM range.
