No, because it's irrelevant. Talking about "electric motor efficiency" is as pointless as talking about the efficiency of the ring and pinion in the axle of vehicle. It isn't where energy is lost. The total system efficiency is what matters. As other posters mentioned, even diesels beat the efficiency of an EV when you measure well to wheel: https://ui.adsabs.harvard.edu/abs/2020SJRUE..24..669A/abstract https://ui.adsabs.harvard.edu/abs/2020SJRUE..24..669A/abstra...
