Why don’t dual motor EVs have the same range as single motor EVs?

574 viewsOtherTechnology

It seems like dual motor EVs have significantly less range. Can’t dual motor EVs run in single motor mode to save range and only use the 2nd motor when absolutely necessary? The motor can’t weigh that much that it contributes to often 50mi difference in range.

As well as additional weight there is also additional mechanical friction with the extra parts of the drive system and motor.
It may even be possible that the motor not in use has to use a small amount of power to compensate for the additional friction.
