From my view weight is the big limiting factor in EV efficiency at lower speeds and Cd becomes more important as you increase your speed to highway numbers and higher.

Engines are important as the company Munro pointed out during their tear downs. They stated that Tesla had by far the most impressive EV motor they have seen based around how they implemented the magnets and their inverter work finally coupled to a battery solution that proved naysayers wrong.

That out of the way, I would not fret over motor differences. It all comes down to, if it passes the initial three features I listed about then concern yourself with, do you like how it looks, how it drives, and does it fit in your lifestyle. In no shape or form think you will save money parting with your current vehicle for a new one however if you already were decided to change cars and EV may fit your lifestyle.

There is a good possibility many EVs will be rear drive which will greatly improve driving dynamics, the ease of packaging opens up many options
