Ferrari team principal Maurizio Arrivabene believes F1 should work to encourage and nurture new teams into the sport, rather than revert to a format of eight teams entering three cars each.

With Caterham and Marussia slipping into administration towards the end of the 2014 F1 season, just nine teams and 18 cars were present on the grid at the United States and Brazilian Grand Prix races, though Caterham did return for the finale with a crowd-funding assisted effort.

Ahead of the 2015 F1 season, ten teams are set to line up on the grid, including Manor-Marussia, which has now formalised its plans to return to action in Melbourne.

However, with the likes of Force India, Lotus and Sauber each signalling their own financial concerns too - which contributed to the former getting just two days of pre-season testing with its new car -, it is feared more teams could fall by the wayside.

With this in mind, a contingency to ensure the grid remains sizeable could see teams forced to run a third car, particularly if the number of teams participating dips to eight.

"It is a move that is seen as unpopular amongst teams, not least due to the extra costs and timeframes associated with manufacturing a third car, with Arrivabene admitting it isn't something he personally supports, even if he says Ferrari is prepared to do so.

"It depends on the situation," he said. "If you are constrained to having to use a third car of course you have to do it, but this is not our final goal. Our goal is to attract other constructors, other teams and to have a grid which is going to be competitive and with as many teams as we can."

"We need to do something to solve the case of there not being enough teams but three cars is not the solution. The solution is to be able to attract more teams, more constructors and a stronger competition."

Ferrari currently supplies power units to Sauber and is set to support Manor-Marussia's burgeoning bid to get back on the F1 grid by supplying 2014 specification engine. It will also support Haas' anticipated F1 entry in 2016.
