– For safety reasons, all team personnel working on a car in a race pit stop will be required to wear head protection.
– Each driver will be provided with one extra set of tires for use only during the first 30 minutes of the first practice session on Friday, to encourage teams to take to the track at that time without having to worry about using valuable tire wear.
– Drivers must now use a gearbox for six consecutive events, an increase from the current five.
– No car may use more than 100kg of fuel for the race, from the time the lights go out at the start of the race to the checkered flag. This will be monitored by the use of an FIA approved fuel flow meter.
– The pit lane speed limit, which is currently set at 60km/h for the free practice sessions and 100km/h for the qualifying practice and race (60km/h for the whole event in Melbourne, Monaco and Singapore), has been amended so it is set at 80km/h for the whole event (except the three races mentioned which would stay at 60km/h for the whole event). This is for safety reasons, as most accidents happen during the race when the speed limit is higher; drivers also have very little chance to practice stopping from 100km/h until the race.
Several changes have also been announced in regards to the 2014 technical regulations.
Measures have been put in place to ensure that the cars do not incorporate a step in the chassis behind the nose. These changes will also ensure that a genuine low nose, introduced for safety reasons, is always used.
The minimum weight limit has been raised by 5 kg, as the power unit is now likely to weigh more than originally expected. The weight distribution has also been changed accordingly.
Electronic control of the rear brake circuit is permitted in order to ensure consistent braking whilst energy is being recovered.
In order to ensure that side impact structures are more useful in an oblique impact and more consistent, they will become standard items made to a strictly laid out manufacturing process and fitted to the cars identically. The impact tests currently carried out will be replaced by static load push-off tests and squeeze tests. This will also help reduce costs as no team will need to develop their own structures.
In order to ensure that the cockpit rims either side of the driver’s head are stronger, the amount of deflection during the static load tests has been reduced from 20 mm to 5 mm.
