In 1957, he won the 1957 Glover Trophy, run to Formula One rules at Goodwood. In his first championship Formula One race, the 1957 Monaco Grand Prix, Lewis-Evans finished fourth in an inferior Connaught Type B, beaten only by multiple winners Fangio and Brooks, and Masten Gregory in one of the dominant Maserati 250F cars. This performance brought him to the attention of Tony Vandervell, owner of the rising Vanwall team, and by the next Grand Prix Lewis-Evans was driving the third Vanwall. The 1957 Vanwall was fast when its engine held together, but not always reliable. Lewis-Evans achieved his best finish for Vanwall when he was 2nd at the year's non-championship Moroccan Grand Prix. He took pole position at the final World Championship event, the Italian Grand Prix, but had to retire with engine problems.
