LONDON - Champions Mercedes are likely to stay in Formula One after major changes come into play in 2021 but that cannot be taken for granted, team principal Toto Wolff said on Tuesday.
The German carmaker's factory team have won both the constructors' and drivers' championships for an unprecedented six years in a row, and next season is the last before a financial, technical and sporting shakeup.
The teams are still negotiating a new agreement with commercial rights holders Liberty Media to replace the one that expires at the end of 2020, and their positions are being staked out.
"Everything indicates that we will stay. But it's not a given," Wolff, who is missing this weekend's Brazilian Grand Prix to deal with such commercial matters, told motorsport.com.
"We are in the middle of discussing the new Concorde Agreement. In connection with this, and independently of it, we are discussing the development of the automobile and its effects on sport," added the Austrian.
