The Ford Sierra Mk I, produced from 1982 to 1987, represented a significant evolution in Ford of Europe's vehicle lineup. Designed as a modern, aerodynamic alternative to traditional rear-wheel-drive sedans, it offered a class-leading drag coefficient for its era and an engaging driving experience thanks to its RWD platform. Available in a variety of body styles including 3-door and 5-door hatchbacks, saloons, estates, and performance-oriented XR4 variants, the Sierra was powered by a range of engines from the efficient Ford Pinto OHC and CVH to the more potent Cologne V6 and DOHC units, as well as a diesel option. Its innovative design, which included independent rear suspension on most models, earned it the European Car of the Year award in 1983 and a Design Council award for its styling, positioning it as a key competitor in the family hatchback segment.
