2010 saw him wrap up the Championship in the inaugural season of the GP3 Series with two rounds to spare and he also became test and reserve driver for Sauber F1. For the next two seasons he juggled his F1 commitments at Sauber with racing in the GP2 Series, finishing 13th in 2011 and third in 2012 (with three wins).
He broke into F1 with a race drive at Sauber for 2013 but it proved to be a difficult rookie campaign, with just one top 10 result. The following season was even tougher, though, and after leaving Sauber at the end of 2014, he spent the following season working as a test and reserve driver for Ferrari before making his return in 2016 with Haas.
Since his exit from Haas, Esteban has raced in a number of different categories, including Formula E with Techeetah and IndyCar with Dale Coyne Racing. Esteban supported our simulator programme in 2018 and joined the Mercedes-AMG Petronas F1 Team as Simulator and Development Driver for 2019. Later that year, he also joined the Mercedes-Benz EQ Formula E Team as Reserve Driver.
