Tesla's motor isn't what drives the range and efficiency; the battery assembly is their key differentiator. Tesla currently has the industry-leading thermal design; it's ability to cool batteries and prevent thermal-based degradation is far more efficient/effective than anything that competitors have yet been able to put on the market.

Supposedly GM's Ultium battery platform will equal or exceed Tesla's batteries, but that remains to be seen as the first Ultium-based cars don't come out until 2H 2021 and all we have to go on right now are press releases.

VW holds some patents and exclusive licenses on solid state batteries, and is planning to go all EV within the next few years, though the SSB autos aren't expected until 2025 at the earliest, assuming VW is able to commercialize the technology.

Range went up about 10% when they switched to the "Raven" motor. That ain't nothin'.
