The Finn is currently in his second season with the German marque and the constructors' champions have an option to retain him for 2020 as well
Valtteri Bottas confirmed to partner Lewis Hamilton at Mercedes in 2019
Finnish Formula One driver Valtteri Bottas has signed a new multi-year deal with Mercedes, the reigning world champions announced at the German Grand Prix on Friday.
The announcement comes a day after Mercedes confirmed Hamilton had signed a new two year deal keeping him with the team until the end of 2020.
Bottas, who joined the team in 2017 to replace Nico Rosberg, has been confirmed for the 2019 season, with the German marque having an option to have him drive for them as well in 2020.
"I'm really pleased. I love working with this team, I love the team spirit, the atmosphere in the team and everyone is pushing so hard for the results," said Bottas in a Mercedes video. "I will keep doing all my best to achieve those results, I will give 100 per cent as always."
Bottas won three times with the team in 2017, including the Etihad Airways Abu Dhabi Grand Prix, and while he has yet to triumph in 2018 he has impressed with his speed.
He has out-performed Hamilton at a number of races and only bad luck with the timings of safety cars and mechanical reliability has prevented him winning.
