Romain Grosjean at the wheel of a Mercedes during the French Grand Prix
The Mercedes team announced via its Twitter account that Romain Grosjean, a young retired F1 driver, will be making his comeback behind the wheel of a championship-winning single-seater.

A few months after his terrible accident in Bahrain, Romain Grosjean will drive an F1 car again, and not just any car. Indeed, as promised by Toto Wolff, the team principal of the Mercedes team, Romain Grosjean will have the opportunity to test drive Lewis Hamilton’s W10, the championship-winning car in 2019.
He will drive in a demonstration show during the French Grand Prix, and then on a full test day.
