Mercedes will remain committed to Formula 1 until at least 2020, says Daimler chairman Dieter Zetsche.
The German manufacturer's involvement in Grand Prix racing has been the subject of recent speculation after it announced its impending withdrawal from DTM and decision to join Formula E from 2019.
Speaking at the Frankfurt Motor Show, Zetsche said: "Formula 1 is linked to our history and our brand.
"It is a component that has helped us develop the brand and make it younger, so for now I do not see a change of strategy until 2021. The Concorde agreement will last until that date and I am not even thinking about it," he added.
Formula 1 will see the introduction of a new era in 2021, based on a future set of regulations currently under being framed.
Zetsche was speaking after Mercedes launched the $5 million Project One supercar, featuring a 1000hp hybrid F1 engine.
"We decided to leave DTM and start the project in Formula E," he explained.
"At the moment this series is a social and PR platform, but we want to help to increase the competition between the teams."
