Re: Spied! Is the 2020 Lincoln MKZ?
RAM is probably the closest you'll get to a Lincoln Truck today. The F-150 is a nice all-around truck, but I don't think it scales as well because it's largely engineered for class-leading payloads and towing. I doubt Lincoln could get what it needs out of an F-150, especially with that suspension system which is a non-trivial thing to civilize unless Ford wants to.
And besides, I doubt Lincoln wants such an obvious rebadge in their ranks again.
