Stirling Moss has the most Grand Prix victories without ever winning the World Championship. The British driver won 16 Formula One World Championship races between 1955 and 1961, a record for a non-champion.
Moss came closest to the title in 1958, when he finished runner-up to Mike Hawthorn by a single point. He was also championship runner-up in 1955, 1956, and 1957, making him one of the most successful drivers never to claim the crown.
His 16 wins came with several teams, including Mercedes, Maserati, Vanwall, and Lotus-affiliated privateer entries. He also won major non-championship events, the 1955 Mille Miglia, and the 1954 12 Hours of Sebring.
David Coulthard and Carlos Reutemann are common mix-ups because they also won many Grands Prix without becoming world champions, but their totals were lower: 13 and 12 respectively. Moss's record concerns World Championship Grand Prix victories, not every race he won in his career.
