The fourth-generation Marquis was produced with four separate engines over its production. Sedans were fitted with a 2.3L inline-4 as standard equipment; a propane-fuel version of the engine was an option. Station wagons were sold only with six-cylinder engines; a 3.3L inline-6 (dating back to the Falcon/Comet) was the standard engine for station wagons and optional on sedans. A 3.8L V6 was optional on both body styles, replacing the inline-6 entirely for 1984. Sold only in Canada from 1984 to 1985, the Marquis LTS was powered by the 5.0L HO V8 (shared with the Mustang).
