Marcus Ericsson (born 2 September 1990) is a Swedish race car driver currently racing for Sauber in Formula One, where he is contracted to the end of the 2018 season.
After a successful début in car racing in 2007 which saw him take the British Formula BMW title with Fortec Motorsport, he moved up into the British team's British Formula Three Championship squad. After finishing as one of the top rookies in the category, Ericsson turned his attentions to the All-Japan Formula Three Championship where he won the championship in his debut year. In 2010, he moved up to the GP2 Series where he secured one victory during his maiden campaign for Super Nova Racing. Between 2011 and 2012, Ericsson drove for iSport. Ericsson completed the 2013 GP2 season with DAMS, and debuted in Formula One in 2014 with Caterham F1.
Born in Kumla, Örebro County, Ericsson's first taste of motorsport came when he was nine years old racing in karts. "I got a call from Fredrik Ekblom, whom I ran in British Formula 3000 and Indy Lights. He now runs a kart circuit and he told me about a nine-year old kid who'd walked in off the street and nearly broke the lap record" recalled Richard Dutton, head of Fortec Motorsport. Ekblom managed to convince Ericsson's father, Tomas, to buy his son a kart and the young Swede stayed in karting for the next four years, "I'd never really thought about racing as a career. My family didn't have the money for me to race formula cars so we never thought about it" Ericsson recalled.
