In 2020 Phil has contested the FIA World Endurance Championship co-driving alongside Filipe Albuquerque and Paul di Resta, claiming victories at Bahrain, Austin, Spa-Francorchamps and Le Mans. Taking the win at Le Mans was also sufficient to secure the LMP2 title, making Hanson the youngest-ever WEC Champion. He will continue with United Autosports throughout the remainder of 2020, once again partnered by Albuquerque, in the European Le Mans Series. With three podiums already secured, including wins at Le Castellet and Spa-Francorchamps, the pair already leads the series. He also partnered two time Formula One World Champion Fernando Alonso and future Mclaren Formula 1 driver Lando Norris at the 2018 24 Hours of Daytona
