Red Bull team principal Christian Horner has called on Formula One chiefs to bring an end to 'predictable' results by changing the current regulations.
Lewis Hamilton has won the last two world championships while Mercedes topped the 2014 and 2015 constructors' standings.
During that time Mercedes have won 32 of the 38 races and clocked 23 one-twos, with Hamilton's closest challenger for his titles being team-mate Nico Rosberg.
Horner believes fans are being driven away from the sport and has urged the likes of F1 chief executive Bernie Ecclestone and FIA President Jean Todt to mix things up ahead of the 2016 campaign.
"Predictable, serial results and serial winning is difficult for any sport," Horner told autosport.com.
"Inevitably, with predictability, people get turned off and it needs a rejig to bring it closer together.
"You can't expect the teams to achieve that, that's for the regulator and the governing body to come up with a set of rules that achieve those objectives.
"The regulations are incredibly stable for next year, so Mercedes will inevitably carry on the dominance, such is their margin.
"They will find gains throughout the winter and will undoubtedly be near the top of the curve."
Horner guided Sebastian Vettel to four consecutive drivers' championships between 2010 and 2013 with Red Bull also emerging as constructors' winners in each of those seasons.
However, the 42-year-old insists the nature of those successes did not harm the sport.
"We were accused of it, but we enjoyed the continued success and longevity of the sport," he added.
"Two of our world championships went to the last race, and we never finished first and second in a championship."
