two thousand seventeen season switches

Tyres are around twenty five percent broader than in 2016, with rear width up from 325mm to 405, and front width raised from two hundred forty five to 305. Tyre diameter has also enlargened very slightly, however wheel rim size remains unchanged at thirteen inches.

As shown in the drawings below from technical artist Giorgio Piola, front wing span is enhanced from 1650mm to 1800mm. Note also that the overall width of the car is up from one thousand eight hundred to 2000mm.

Rear wing and rear diffuser

As shown in the drawings below, the height of the rear wing is diminished to a maximum of 800mm, down from nine hundred fifty previously. Meantime, the diffuser is more powerful thanks to enhanced height – up from 125mm to one hundred seventy five – and width – up from 1000mm to 1050. It is also longer, now extending ahead of the rear wheel axle line.

Sidepods

As shown below, bodywork is now broader, with maximum width up from 1400mm to 1600mm.

Weight

Maximum weight is enhanced from 702kg to 722kg plus tyres.

A rule switch has been made to prevent drivers stockpiling spare power unit elements. During any single event, if a driver introduces more than one of a power unit element that is subject to a grid penalty, only the last element fitted may be used at subsequent events without further penalty.

A number of switches have also been introduced aimed at reducing power unit costs, assuring supply for customer teams, and closing the spectacle gap inbetween engines:

– the power unit price for customer teams has been diminished by €1m per season compared to 2016.

– to ensure the supply of power units to customer teams, the homologation procedure now includes an ‘obligation to supply’ that is activated in the event of a team facing an absence of supply.

– the previous ‘token’ system for in-season engine development has been liquidated.

– Additionally, constraints on power unit part weights, dimensions and materials, and on boost pressure, are being introduced in two thousand seventeen and in 2018.

Wet-weather standing starts

If a safety car is deemed to be required for the beginning of a race due to moist weather, unlike previously a normal standing embark will occur once the track is deemed safe to race. The process will see the safety car come back to the pit lane and the cars assemble on the grid for the begin.

Helmet livery

Drivers must proceed to use essentially the same helmet design at all races for effortless recognition of the driver in the car. However, each driver is now permitted to use a special livery at one event of his choosing, such as a home race for example. Drivers will also be permitted to switch their helmet liveries if switching teams during the season.
