Fernando Alonso has won two F1 World Drivers' Championship titles in 2005 and 2006 with Renault, and has won 32 Grands Prix across 22 seasons. In endurance racing, Alonso won the 2018–19 FIA World Endurance Championship and is a two-time winner of the 24 Hours of Le Mans with Toyota, and remains the only driver to have won both the Formula One World Drivers' Championship and the World Sportscar/World Endurance Drivers' Championship; he also won the 24 Hours of Daytona in 2019 with WTR.

In 2018, Alonso finished fifth at the season-opening 2018 Australian Grand Prix and took nine top-ten finishes. He out-qualified his teammate Stoffel Vandoorne at every race and drove quickly and aggressively, yet became increasingly annoyed with certain drivers and his commitment to F1 waned after McLaren stopped developing their car to focus on 2019. Alonso finished 11th in the Drivers' Championship with 50 points.
