He was named as reserve driver for the Renault F1 team in 2016 and began the year driving a works Mercedes-Benz in the German Touring Car Championship. Ninth at Zandvoort to score his first DTM points of the season, he left the series to make his F1 race debut for Manor Racing at Spa-Francorchamps. He finished all nine remaining races and excelled in the Brazilian rain to challenge for points – only dropping to 12th in the closing laps.
