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

600 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.

A lot of answers here but the biggest way to lose a ton of range in the US is this:

EPA test weight classes. If you add another motor which pushes you into a higher weight class, your EPA range testing needs to be ballasted up to the middle of that higher weight class. Ie: if your RWD version weights 4999 lbs you remove weight to get to the middle of the weight class and do your range testing with that lower mass. If your AWD version weighs 5000 lbs you do your EPA range testing ballasted up. The worst case would be if the additional motor and structure pushes you up two weight classes
