A standing start will used following a Safety Car period except within the first two laps of a race or during the final five laps.
The proposed change proved unpopular with F1 fans when it was announced. In an F1 Fanatic poll 67% opposed the rules change with 20% in favour.
Changes will also be made to the technical rules governing car noses “to ensure improved safety and to provide more aesthetically pleasing structures”.
Among the other changes to the design of the cars is the requirement of two-stage wheel fasteners to reduce the chance of a wheel becoming detached from a car.
Further new regulations will ensure brake discs rotate at the same speed as wheels and enforce the use of lighter materials for skid blocks.
A series of new rules have been introduced with the aim of reducing costs.
The current parc ferme restrictions, under which teams are restricted in how they can modify their cars, will now begin after final practice instead of qualifying. The Friday night curfew will increase from six hours to seven next year, and will be extended by a further hour the year after.
Teams will be allowed to use only four complete power units during the season instead of the five permitted this year. However the FIA noted this change will not be applied “if there are more than 20 races in a season”.
Wind tunnel and computational fluid dynamic (CFD) testing will be subjected to tighter restrictions, as will real-world track testing.
In-season track testing will be banned again, and the three four-day pre-season tests must all take place inside Europe. Two of this year’s tests were conducted in Bahrain.
However some teams have criticised the scope of the cost cutting rules changes, saying they do not go far enough.
