In 1966, Salmon began the year with a fourth place at the Brands Hatch 500 mile race alongside David Hobbs in a Ferrari 250 LM entered by David Piper. This was followed by a non-finish at the Spa 1000 km race in a Ferrari 365 P2, entered and co-driven by Piper and also in the Nürburgring 1,000 km in a Ford GT40 entered by Ronnie Hoare and co-driven by Ireland. At Le Mans, he was partnered by Hobbs in a Ferrari Dino 206 S entered by Maranello Concessionaires. However, the car retired after 14 laps. Domestically his best result was second with a GT40 at the Eagle Trophy at Brands Hatch in August.
