EV West fell out with jack Rikard and built their business on hanging a DC motor on the VW transaxle and now they use Tesla. Both suboptimal (weight and clutch lifespan in the first case, overpowered in the second). The Tesla drivetrain needs a Quaiffe differential.

Arcimoto have specced a twin motor drivetrain with limited slip and torque vectoring.
The 'primary business' is disrupting transportation. MLM furthers the goal.
