At his first outing in a go kart, Ericsson set the fastest lap recorded at the circuit. This was just the beginning of his career in motorsport. Soon, he started to race in national races and received help from IndyCar driver Kenny Brack as he made his way into Formula One.
In 2007 he won the British Formula BMW championship, with 7 wins. Moving to British Formula 3 the next year, he finished 5th overall. He also raced in European and Japanese F3, winning the Japanese series in his first year.
In 2010 he raced in GP2 with the Super Nova team. In the Valencia street race, he claimed his first victory. Despite this, he finished just 17th overall. Moving to the iSport team for 2011 he had more success, but failed to win a race. The next season saw him win another race – the first in 2 years – and had many consistently strong performances. He raced for the DAMS team in 2013, but had a terrible start to the season, scoring just 9 points in 10 races. However – thanks to a win at the Nurburgring and multiple podiums – he finished 6th overall.
Although the 2013 season started badly, Ericsson impressed the Caterham team enough to get a drive in 2014. In an uncompetitive car, Ericsson failed to score points but managed to finish 11th at Monaco after 8 cars retired from the race.
Confirmed to race at Sauber for 2015, Ericsson’s second season in Formula One was more successful. He scored nine points, finishing eighth in the opening race. However, 2016 was a much harder year for the team as a whole, so far he is yet to score a point.
