The Capri Mk III was referred to internally as "Project Carla", and although little more than a substantial update of the Capri II, it was often referred to as the Mk III. The first cars were available in March 1978, but failed to halt a terminal decline in sales. The concept of a heavily facelifted Capri II was shown at the 1976 Geneva show: a Capri II with a front very similar to the Escort RS2000 (with four headlamps and black slatted grille), and with a rear spoiler, essentially previewed the model some time before launch. The Mk III featured improved aerodynamics, leading to improved performance and economy over the Mk II and the trademark quad headlamps were introduced.
At launch the existing engine and transmission combinations of the Capri II were carried over, with the 3.0 S model regarded as the most desirable model although the softer Ghia derivative with automatic, rather than manual transmission, was the bigger seller of the two V6-engined models.
