Plans for higher-performance F1 cars and increased driver head protection next season have taken a step forward with the agreement of a new proposal to increase downforce and tyre widths.
The F1 Commission has agreed to postpone the deadline for agreeing the 2017 sporting and technical regulations until the end of next month.
The new plans for 2017 will see car widths increase from 1.8m to 2m, front tyre widths increased by 60mm and rear tyre widths by 80mm. Front and rear wing widths will be increased and the rear wing reduced in height. Further alterations to the technical rules will allow designers more freedom to increase the downforce produced by the cars:
|Front tyres||245mm wide thread||305mm wide thread|
|Rear tyres||325mm wide thread||405mm wide thread|
|Legs||+/-5° profile incidence||+/-10° profile incidence|
|Front wing||1650mm span||1800mm span, swept plan view shape, simplified endplate legality|
|Rear wing||750mm wide, 950mm high||950mm wide, 800mm high|
|Rear wing endplates||Rectangular endplate||Swept endplate in side view and tucked in front view|
|Floor Step plane||1400mm max width, 1300mm min width||1600mm max width, 1400mm min width|
|Floor edge radii||<50mm constant||<100mm variable|
|Reference plane start point||330mm behind front axle||430mm behind front axle|
|Plank||Homogeneous plank||Pocketed plank for weight saving|
|Diffuser||125mm high, 1000mm wide, starts at rear axle||175mm high, 1050mm wide, starts 175mm ahead of rear axle|
|Bodywork Width||1400mm max width||1600mm max width|
|Sidepods||No constraint||Swept leading edge in top view|
|Bardgeboards||Big exclusion zone behing front wheels||Reduced exclusion zone allowing for larger bargeboards|
|Weight||702kg max weight||722kg max weight + tyres (est 5kg)|
The FIA also plans to introduce new cockpit protection for next season. The ‘halo’ concept is described as “currently the preferred option”, though others are under discussion.
