"Was also marketed as the Mercury Capri, slightly sportier but still an Escort."
After the European Capri and the 1974-78 Mustang II, the Capri name was applied to the Fox-body Mustang's Mercury sibling beginning in 1979. The Mercury Lynx was the counterpart to the Escort in the U.S.
As a sidenote; the Ford EXP and Mercury LN7 were dporty two-door hatchback spinoffs from the Escort and Lynx.
The rest of the story: Lincoln-Mercury Division of FoMoCo was advertised as "The Sign of the Cat" during most of the 1970s. Of course, that feline rode the (coat)tails of the Cougar which debutted in 1967 as an upscale Mustang and grew to be on the Thunderbird chassis. Typically, Ford's birds and ponies were paired with cats as Pinto/Bobcat rounded (no pun intended) out the Mercury offerings. Alas, the Ford Maverick compact car paired with Comet--a moniker applied to that marque's Ford Falcon badge-engineered Mercury.
