The margin of the exemptions for new manufacturers, the new Technical Regulations of the WEC pattern a series of measures in relation to the limitation of the tire, the hours of work in the wind tunnel and the visibility of the vehicles in pit. In this aspect, the FIA and the ACO want the Endurance World is more accessible to the amateur and at the same time also to the manufacturers decreasing the costs of implementation. All in all, it also opens the door to variety strategic in spite of the reduction of sets of tyres.
The tires are the epicenter of the changes in Technical Regulation approved by the FIA for the World cup of Resistance of 2017. In the case of the LMP1 and for the events of 6 Hours, the set of available tires is reduced by 33% and the teams only get to enjoy three sets of tires for free and four to the classification of four and six who had at their disposal in 2016. In addition, the use of wind tunnel for manufacturers of LMP1 passes from 1,200 to 800 hours.
For his part, in GTE each brand should choose a maximum of three tire specifications for each model of car, and may be different between GTE-Pro and GTE-Am. Two of these compounds should be selected 15 days prior to the first event, while the specification extra you can choose up to 15 days prior to the 24 Hours of Le Mans. These three types of tires will be frozen for the entire season except for changing the car, or provider, change this last can be done once per season. In GTE-Pro are reduced sets of tyres for the races of 6 Hours in the same proportion as that in the LMP1.
finally, the Technical Regulations of the WEC schedule as from 1 hour before the first session until 1 hour after the last session of each day the visibility of the interior of the garage must be absolute, avoiding any kind of accidental blockage (stacks of tires, parts of the body) or voluntary. The goal is that, without hindering the work of the technicians that at a given point in time can be in front of the vehicle, to avoid the typical human barriers that impeded the vision of the car for the fans and the FIA stewards.
