Here is why Ford nixed in-wheel motors in F-150 Lightning electric truck

In Ford’s reveal of the 2022 F-150 Lightning on Wednesday, the automaker designed observe of the electric powered truck’s “inboard motors.” 

So we asked the company’s world-wide EV item enhancement director Darren Palmer regardless of whether it considered in-wheel hub motors for the F-150, and why it dominated them out. 

Palmer appropriate away confirmed that Ford had viewed as them and opted against the layout. He claimed it arrives down just to becoming common with what an F-150 needs to be—because it sells about a million of them a year—and understanding an in-wheel motor won’t suit the bill.

“The very best tradeoff for all the points it is received to do, we believe that, was in a secured, harmless, inboard motor, where by the high-priced section is inside, wholly sealed, and impervious that is our option,” he stated.

The everlasting-magnet motors made use of in the F-150 Lightning have internal controllers and transaxles they are also applied in the E-Transit electric powered vans, and the models are built at Ford’s Van Dyke Transmission plant in Michigan. The two motors in the F-150 Lightning are identical, albeit with marginally various reduction gearing utilised involving the entrance and rear units and an e-locker operate for the rear motor. 

Palmer pointed out that when you are towing anything, you count on the friction brakes a great deal more, and they didn’t want just about anything interfering with them.

“Wheels get a lot of punishment, so they are on the unsprung mass of the merchandise,” he extra. “Anything in the unsprung mass is heading to get battered by every solitary movement of the wheel.”

A single other rationale they opted versus in-wheel motors was the seals, Palmer claimed. “Sealing factors within wheels is also super-complicated with all the crud and mess ground into it on a everyday foundation,” he said, summing that they mirror the proper tradeoffs “for a item that is going to be performing.”

Ford pointed out that the Lightning gains from 7.4 million client-equivalent F-150 progress miles ahead of getting place into consumer palms. 

To examine, Lordstown Motors claimed in March that it has about 20,000 real-globe test miles on its Endurance pickup, as well as about 200,000 miles on the motors them selves. It is the 1st use of in-wheel hub motors in the industry—although the startup Aptera also plans to use them in a photo voltaic-supplemented, performance-focused 1000-mile EV.

Lordstown previous month pulled its Endurance from the Rating San Felipe 250 off-street race soon after it considerably underestimated the vitality essential to electric power the truck—although it noted the hub motors done effectively and stood up to the take a look at.

Palmer reported that it isn’t just sturdiness although. Ford also wanted to aid a huge assortment of driving problems. The F-150 Lightning can accelerate to 60 mph in the mid-4-2nd array, in accordance to Ford—faster than the higher-overall performance gasoline F-150 Raptor version—and is electronically limited to 110 mph. It can likely get up there quickly plenty of with its inboard motors, but Ford located hub motors never execute nicely from close to 80 mph on up.
