Why not develop an axel with an integrated motor? It’d be easily scaled to any vehicle with a solid rear axle. Fill the engine bay with batteries… It seems like an easy approach to get a widely applicable EV conversion kit. Offer a few widths and diameter axles… Is it bad to have the motor in an unsprung position?I see hub motors, so I think not. I guess air conditioning would be another thing.
I figured axles generally only vary in width and diameter. Spring perches and other suspension attachment points can be easily welded on. Basically use the stock suspension. My little Suzuki uses leaf springs, so it’d be very simple.
