Possibly the use of Continental's Intelligent Glass System throughout vehicle. Welll, we know Continental used the Ford Mondeo to test their IGU system. And we know that Ford has invested $500 million that will help Rivian's first two EVs get off the ground.
Then there's this interesting bit of speculation from Business Insider as to where the Rivian/Ford partnership might be headed:
In a statement, Ford and Rivian said they had "agreed to work together to develop an all-new, next-generation battery electric vehicle for Ford's growing EV portfolio" using Rivian's platform.Neither company indicated whether that would be a pickup. Ford's F-150 pickup has been the best-selling vehicle in the US for decades, and the carmaker has said it intends to electrify the truck. That process is now well underway. BIG "if," but the entire F-Series sold about 900K trucks in the US in 2019. The F-150 accounted for over half of them. Even if it's not the F-150, to me Ford still sounds like a good bet as a Continental IGU customer because:
Ford said in March 2018 that globally it will be creating 16 fully electric vehicles and 40 electrified vehicles through 2022.
