For 1957, Mercury redesigned its model range, with a wheelbase sized between Ford and Lincoln. In a move upmarket, the slow-selling Medalist was discontinued, with the Monterey becoming the standard Mercury line. Previewed by the 1956 XM-800 concept car, the Turnpike Cruiser (the pace car of the 1957 Indianapolis 500) was slotted above the Montclair, distinguished by its quad headlamps and retractable rear window. In line with Ford, Mercury station wagons became a distinct model line, with the Commuter, Voyager, and Colony Park; all Mercury station wagons were hardtops.
