In Ford’s reveal of the 2022 F-150 Lightning on Wednesday, the automaker manufactured take note of the electric truck’s “inboard motors.”
So we asked the company’s international EV merchandise advancement director Darren Palmer regardless of whether it regarded as in-wheel hub motors for the F-150, and why it dominated them out.
Palmer appropriate absent confirmed that Ford had considered them and opted in opposition to the format. He reported it comes down only to being acquainted with what an F-150 needs to be—because it sells about a million of them a year—and being aware of an in-wheel motor will not suit the invoice.

The permanent-magnet motors utilised in the F-150 Lightning have internal controllers and transaxles they’re also made use of in the E-Transit electric powered vans, and the models are made at Ford’s Van Dyke Transmission plant in Michigan. The two motors in the F-150 Lightning are similar, albeit with somewhat different reduction gearing employed between the front and rear units and an e-locker purpose for the rear motor.
Palmer pointed out that when you’re towing anything, you depend on the friction brakes significantly more, and they didn’t want everything interfering with them.
“Wheels acquire a whole lot of punishment, so they are on the unsprung mass of the merchandise,” he included. “Anything in the unsprung mass is going to get battered by each and every one motion of the wheel.”
One other reason they opted against in-wheel motors was the seals, Palmer said. “Sealing points within wheels is also super-difficult with all the crud and mess ground into it on a day-to-day basis,” he said, summing that they mirror the ideal tradeoffs “for a merchandise that is heading to be working.”

Ford observed that the Lightning added benefits from 7.4 million consumer-equal F-150 development miles in advance of staying put into shopper hands.
To compare, Lordstown Motors reported in March that it has about 20,000 serious-earth test miles on its Stamina pickup, in addition about 200,000 miles on the motors by themselves. It is the to start with use of in-wheel hub motors in the industry.
Lordstown last thirty day period pulled its Stamina from the Score San Felipe 250 off-road race soon after it dramatically underestimated the energy wanted to electrical power the truck—although it described the hub motors carried out effectively and stood up to the take a look at.
Palmer explained that it isn’t just longevity though. Ford also needed to assist a broad variety of driving circumstances. The F-150 Lightning can speed up to 60 mph in the mid-4-next variety, according to Ford—faster than the superior-effectiveness gasoline F-150 Raptor version—and is electronically confined to 110 mph. It can very likely get up there promptly enough with its inboard motors, but Ford found hub motors really do not execute effectively from about 80 mph on up.
