Lincoln Mark Coupes—On paper, both of these Lincolns might sound the same: all-wheel drive, twin-turbo EcoBoost V6 hybrid drivetrains, two-door bodies with full-boat luxury interiors. In reality, they couldn't be more different. Illustrated at the top is my Mark GT, a long and relatively low luxury coupe with wraparound glass and a thick B pillar, based on the MKT. The bottom version is a much shorter and taller, more futuristic Mark, based on an Aston Martin concept, with roof styling more akin to the pillarless Marks of yore. I'd say the top version could be sold today with no problem, and the bottom one might be five-years in the future. As much as I am a fan of Harley Earl's "Longer, lower, wider" mantra, the reality is cars of the future will become shorter, taller and narrower, to take up as little physical space as possible for their stated automotive missions.
