Tooker said Magna has several patents on the technology. One key patent is on the rear-window defroster, which operates continuously. Unlike the sliding rear window on the current truck, which loses the defrost function if the window is open slightly, the movable panel defrosts regardless of whether it’s open or closed, he said.
The new window assembly weighs 20.74 pounds, down from 21.73 pounds on the current version, for about a 4.5 percent reduction in weight. That may sound small, but Tooker said Ford asked Magna to look for every possible opportunity to trim weight.
The new F-150 will be up to 700 pounds lighter than the current F-150, largely because the steel body is being replaced by aluminum.
Tooker said Magna was besieged by inquiries from other carmakers when it first showed the seamless rear window at the F-150’s world debut in January at the Detroit auto show.
The technology is not licensed exclusively to Ford, so Magna can sell it to other customers, he said. But he emphasized that Ford has always been a leader in trucks.
Ford and Magna both said they are exploring other applications for the technology.
