As an engineer, I have always wondered why Tesla don't go with multi-gear transmission, just like ICE cars. The advantage is that the electric motor only needs to output very low RPM in order for the car to achieve highway speed. That means less electrical power is needed overall, and the range can be extended greatly even if the battery capacity is unchanged at 70 or 90 kwh. The heating issue of battery and electric motor is also greatly reduced, which means Tesla can do aggressive driving for much longer. On top of all that, the top speed of Tesla will probably reach 190 mph instead of the current 155 mph limit. You can pretty much solve multiple major issues of electric car by adding multi-gear transmission.
Any idea on why Tesla cars are still stuck with single-gear transmission?
