“It's a very special feeling to be asked to drive for Mercedes-Benz EQ in Formula E, and I am honoured that the team have chosen me as one of their two drivers,” said de Vries.
“Formula E is a great platform that has already established itself as one of the biggest and most professional racing series outside Formula 1.
“Mercedes are aiming to be contenders for race wins and championship trophies,” he added.
