The Mk1 Lotus Cortina, officially known as the Ford Cortina Lotus, debuted in 1963. Its heart was the Lotus-developed 1.6-liter twin-cam engine, based on the Ford Kent block, which produced around 105 bhp, a significant increase over the standard Cortina’s power output. This engine was paired with a close-ratio gearbox, and the car featured a unique green stripe and Lotus badges, distinguishing it from regular Cortina models.

Significant modifications were made to improve handling and performance, including lightweight alloy panels for the doors, hood, and trunk, as well as aluminum casings for the gearbox and differential. The suspension was heavily revised, with coil springs and dampers at the front and a leaf-sprung rear, modified to incorporate trailing arms and a Watts linkage, ensuring better stability and cornering.

The Lotus Cortina Mk1 quickly established itself in the world of motorsport, excelling in touring car championships and rallying. It achieved numerous victories, including winning the British Saloon Car Championship and making a notable impact in international rallying. Its success on the track helped to cement the Lotus Cortina’s reputation as a high-performance vehicle and contributed significantly to its desirability among enthusiasts.
