F1 supremo Bernie Ecclestone has revealed that some teams could run with three cars in 2015 if the paddock is restricted to eight teams.

With some teams struggling financially, speculation has increased in recent weeks about the possibility of increasing the number of cars per team.

Marussia, Caterham, Lotus and Sauber have all been noted to have financial concerns, but it remains to be seen what the future holds for them before the end of the campaign.

Lotus have struggled despite finishing fourth in the Constructors’ Championship last season. Former driver Kimi Raikkonen left the team after claiming they hadn’t paid his salary. Sauber are also under threat according to reports from the paddock, despite team principal Monisha Kaltenborn says they will still be driving in 2015.

Adam Parr, the former chairman of Williams, claimed after the Italian Grand Prix that teams will switch to three cars in 2015 and Ecclestone has admitted there is a chance.

He has recently admitted that he would rather seem teams run with three cars and be competitive than teams struggling at the wrong end of the grid.

The likes of Mercedes and Red Bull have dominated the leaderboards in the last four seasons, and Ecclestone is hoping a different approach will see a more competitive field.

He told Sky Sports News HQ at the Singapore GP: “We have a regulation that says if we lose three teams the other teams will run three cars.”
