Monisha Kaltenborn has said that she continues to campaign for a more level playing field in Formula 1.
Together with her Force India counterparts, the Sauber co-owner and boss is waiting on the next steps after formally complaining about F1's income and rule-making processes to the European Commission.
"Yes, and this struggle continues," the Indian-born Austrian told Swiss newspaper Blick.
"Take the Premier League in England. There, last place in the championship gets only slightly less money than the champion, because the big ones already have an advantage with more sponsorship and advertising revenue.
"With a system like that, a club like Leicester can win the title. But in Formula 1, the big teams get multiples more than the smaller teams. The distribution of money and privileges when it comes to the rules are a distortion of competition."
Indeed, Sauber is currently struggling merely for survival, and is now faced with the task of preparing for radically different chassis rules for 2017.
Asked if the Swiss team is already working on next year's car, Kaltenborn confirmed: "Yes.
"The cars will be wider and more aggressive, but it's also even more expensive, because the big teams determine where we are headed with the rules."
Kaltenborn has ruled out cutting costs by emulating Haas's 'B team' approach to F1, and she also played down the likelihood that Sauber might turn its attention to Formula E or Le Mans.
"I can't imagine it, because Formula 1 is our core business," she said.
Sauber remain pointless so far in the 2016 championship.
