STORY OF THE DAY: Cortese’s Mille Miglia Ends Before Brescia

Franco Cortese and Adelmo Marchetti started the 1948 Mille Miglia in Ferrari 166 S number 10 but did not reach the finish. Their retirement contrasted with the victory of the sister Allemano coupé, yet their entry formed part of Ferrari’s first successful assault on the post-war road classic.

The defining feature of their day was attrition. The Mille Miglia subjected cars to changing surfaces, weather and sustained mechanical stress over roughly 1,600 kilometres. Cortese and Marchetti joined the many crews eliminated, while Biondetti and Navone carried Ferrari’s challenge through to Brescia.

The 166 S developed Ferrari’s early tubular-chassis sports racer around a two-litre version of the Colombo-designed 60-degree V12. Its light construction and flexible engine were conceived for mixed road circuits, but even an agile, powerful car remained vulnerable to the relentless punishment of the Mille Miglia.

Cortese was the Italian driver who had given Ferrari its first competition victory at Rome in 1947 and remained central to the factory’s early development work. Marchetti served as his Italian co-driver, sharing the navigational and mechanical responsibilities that made Mille Miglia partnerships fundamentally different from ordinary circuit-racing pairings.
