The Open category allows teams to use 24 liters (6.3-gallons) of fuel a race (rather than 20 liters/5.28 gallons in factory 1) and have access to 12 engines for the year (rather than five for the season in Factory 1), but all entrants must all use the same Magneti Marelli software. Open entrants also get access to a softer rear tire option and unlike the Factory 1 class there is no freeze on engine development.
However if Ducati, or another Open team, scores a race win, two seconds or three thirds they are immediately promoted into the Factory 2 class were they will be limited to 22.5-litres of fuel per race and nine engines for the season. Three wins in the Open class will mean the tram also loses the concession to have a wider choice of tires, but they will still be allowed to continue develop engines during the season.
In the run up to the first MotoGP race of 2014 this weekend in Qatar, the GP Commission has also now confirmed that any manufacturer with a Factory entry that has not won a dry race in the preceding season, automatically gets the same benefits as Open entries, meaning Ducati's switch was ultimately unnecessary as it has not won since 2010. Suzuki, which will rejoin the series in 2015, is set to get the same allowance.
