Lewis Hamilton on Friday revealed he had signed nine-time world rally champion Sebastien Loeb for his Extreme E team, a motorsport series aimed at raising the profile of global environmental issues.
Also joining the seven-time Formula One world champion's team is Spain's Cristina Gutierrez, who in 2017 became the first woman to finish the Dakar Rally.
Loeb and Gutierrez will race for the X44 team in the inaugural Extreme E season which begins in 2021.
"I'm delighted to welcome Sebastien and Cristina to X44," said Hamilton.
"They are both incredible drivers and I'm looking forward to seeing what they're going to do out there at each race.
"Cristina is an upcoming talent with a great future ahead of her, and Sebastien is a driver I have admired for so many years so I'm so proud and excited to have them on board."
The championship, which features electric off-road SUV vehicles, will start in March.
It will be raced in five remote locations deemed to be already damaged or severely under threat of climate change from a range of issues including melting ice caps, deforestation and rising sea levels.
The five sites chosen include races in the Amazon region of Brazil and in the Arctic in Greenland.
