The works team contested the mighty Mille Miglia and after testing Wyer’s head engine specialist Jack Sopp handed him a grubby note reading: “John – These are bloody good engines. Tell the boys to keep them on the island and we can win”. Into 1955 Wyer would recall: “We concentrated our efforts upon the DB3S, since we had nothing even in concept form to replace it and we believed there was still a lot of life in it… 1955 was undoubtedly the high peak of the DB3S. A very good car it was now approaching its fourth year, a long time in the life of a racing car. We had put all we knew into the 1955 car and there was little left for us to do in the way of development. However, we would continue to use it, with minor improvements, in 1956 until we had a replacement”.
He signed on Stirling Moss for 1956 and admitted: “In fact, we were not really ready for Stirling in 1956 because we did not have a car which was good enough for him. With the possible exception of Fangio he was, beyond dispute, the greatest driver in the world. In his inspired hands, the DB3S, approaching retirement, became almost competitive, as he was to demonstrate. But too often he was using his very great abilities to keep up with the competition, not to beat them…” One reward was another second place in the Le Mans 24-Hour race, Stirling co-driving with Peter Collins, who with Belgian journalist/driver Paul Frere had also piloted a sister DB3S into second place there the previous year.
In reaction to the Le Mans disaster of 1955, for their 1956 24-Hour race the organizing ACO applied a 2.5-litre limit on sports-prototype cars while allowing ‘production’ sports cars unlimited engine capacity. Wyer again: “The DB3S crept in under the ‘production’ regulation, as did the D-Type Jaguar, because we had built the necessary minimum number. We were then permitted to change almost anything we liked. For example the (1956) DB3S ran with twin-plug cylinder heads and disc brakes, neither of which were part of the ‘production’ specification, and the Jaguar had fuel injection. The whole thing was rather farcical…”
