Mercury's revived big performance car, the 1966 Mercury S-55, returned as a separate series after a two-year absence. It featured "Torque Box" construction -- frames individually tuned to minimize noise and harshness -- a standard 428 big-block V-8, heavy-duty chassis, plus a sporty bucket-seat interior. Styling was square and clean "in the Lincoln Continental tradition," as the ads put it. Few were sold, although Mercury generally had a successful big-car year in 1966.
