Corrective work in progress continues on the third generation single-seaters, which will officially debut in the race in Mexico City in January. After the difficulties faced with the batteries supplied by Williams Advanced Technologies, which manifested reliability problems dictated by vibrations when crossing the curbs, Formula E was unable to develop the quick charge system in time in the race, postponing the return of the pits. stop late in the season. It is also recent news of how Gen3s may be equipped with an auxiliary braking system at the rearand after the violent accidents that occurred in the test phase.
This was reported by the editorial staff of TheRace.comwhich reveals how the proposal is under evaluation and that in any case it will not be implemented in time for the Valencia tests. The third generation single-seaters were designed without rear brake discs, making use only of the braking force of the rear generator, whose recharging power has risen from 250 to 350 kW, while maintaining the front hydraulic system. However, the loss of power and the electronic problems encountered on the new accumulators have highlighted how, in the event of a power failure, the drivers find themselves completely without rear brakes, with only the front system at that point to brake the single-seater. Formula E would thus be evaluating, in agreement with the teams, the addition of brakes on the rear axle as a redundancy tool, useful for stopping the car in the event of failure of the rear generator to intervene.
Interviewed by the portal The RaceAlessandra Ciliberti, head of the Gen3 project, explained how cars would make use of a mechanical system whose use would be strictly limited: “It would be regulated to be used only under specific conditions, where it is necessary. It’s still a car without hydraulic brakes at the rear, that doesn’t change. By their very nature, teams and drivers push the limits of the cars in testing and all this is only due to the fact that it is the first time we have had a single-seater without mechanical rear brakes. It is important for us to protect the riders, the manufacturers and the championship, so we took the decision together, after discussions with the organizers and manufacturers. Everyone agreed that perhaps it would be better to add a secondary braking system”. In an issue of absolute seriousness such as that of security, however, irony was not lacking. When asked about it, Jean Eric Vergne expressed himself as follows on the current lack of rear brakes on his car for next season: “By now I’m used to being stripped of car parts and still going on. My Formula E car had the rear discs removed and it works just as well, while my Peugeot 9X8 had the rear wing removed, but it generates quite a lot of downforce. As long as I have four wheels and an engine, I’m good to go.”
