Mercedes has made the announcement of the retention of Valtteri Bottas to complete its driver line-up for 2019 Formula 1 season.

Following the news of Lewis Hamilton extending until the 2020 season, the German manufacturer has also re-signed Bottas for another season in 2019 in a multi-year contract – with an option of retaining Bottas in 2020.

The Finn joined Mercedes in a short notice last year and has done himself well within the team. After few years of tensions between Hamilton and Nico Rosberg, the influx of Bottas brought the much needed harmony within the team.

“It is great news that I will be racing for Mercedes in 2019 and it is nice to announce it here in Hockenheim – not just the home race for Mercedes but also the circuit where I took my first ever single-seater wins back in 2007,” he said.

“This year, with a full winter of preparation, I have been able to make a good step forward – and I believe that there is still more to come. We have not been so lucky in the races this year but the team knows how I am performing, and this is a great sign of confidence in me and my driving.

“I enjoy working with the team, and also being team-mates with Lewis – we have a good relationship, honest and straightforward, and always aiming to get the right results for Mercedes.

“We have a big battle on our hands right now, so it’s good to have the future clear for everybody – it means we can have a full focus on the championship fight. Obviously, my goal is to keep performing at a high level – and to make it a no-brainer for the team when it comes to deciding their plans for 2020 as well.”

Bottas has scored three wins so far with Mercedes – all of which came last year and has 14 podiums in the one and a half years combined. This year he has particularly been unlucky, missing on race wins on couple of occasions.

Team boss Toto Wolff added: “We are very pleased to extend Valtteri’s contract with Mercedes for another season at least – and to be able to confirm an unchanged driver line-up for 2019, ahead of our home race in Hockenheim.

“Valtteri’s performances have been excellent this season and, if not for our mistakes and his misfortune, he could be leading the drivers’ championship at the moment. When we took the decision in favour of Valtteri for 2019, it wasn’t just about his undoubted speed and work ethic, but also a question of character.

“His relationship with the team, including Lewis, is open and trusting, without any politics at all. Those are the ingredients you need when you’re fighting strong rivals in both championships and they mirror the values inside the team. I am very excited to keep Valtteri in the team and look forward to celebrating many more successes with him.”

The double announcement shows the intent for Mercedes to keep the working relationship for a longer period of time so as to eke out as much performance as possible. However, it leaves its junior driver Esteban Ocon in a place of bother who will have to wait for more.
