F1 teams discussing winter break in 2019
Formula 1 teams are discussing the potential for a winter break in December 2019.
The initial idea is for a factory shutdown to be between December 24 to January 1, running under the same arrangements as the long-established 14-day summer break, in which teams can only maintain a skeleton staff.
The key items prohibited in the summer shutdown are wind tunnel running, CFD operation, production of parts, sub-assembly of parts and assembly of cars.
That also includes "any work activity by any employee, consultant or sub-contractor engaged in design, development or production".
The idea, which is understood to have originated at the last meeting of the Technical Working Group, was discussed further by team managers at a meeting of the Sporting Working Group in Interlagos on Thursday.
The matter is now likely to be referred to the Strategy Group.
At this stage, any decision for December 2019 will have to be agreed unanimously, because changes would have to be incorporated into next year's rules.
The break would also impact development for the 2020 season.
There could yet be resistance from the teams, which routinely work through the winter period.
Some have pointed out that engineers from countries such as Japan even work on Christmas Day.
