Lordstown Motors should pull the plug on the current version of the Endurance electric pickup and reconfigure the drivetrain. The immediate goal of the troubled EV startup should be to cut engineering and component costs, increase speed to market and add a megadose of simplicity.
Here's how to do that: Replace the four electric in-wheel hub motors with just one off-the-shelf electric rear axle that could be bought from American Axle, Dana, Magna or another supplier.
This one change certainly would require a redesign of the rear section of the Endurance's steel frame, but it would pay dividends. The power electronics would be far less complex. Dropping three motors would dramatically reduce weight. No longer would heavy cables and cooling lines need to be routed to each motor. And those motors are no lightweight parts on their own.
