GP Week : Issue 233
Pirelli hopes to spice up the racing next with reintroducing tyres that fall off a cliff in terms of performance. it comes after somewhat predictable races in 2015 that have seen teams able to run one stop strategies in some races - although Nico Rosberg won in Brazil after stopping three times. "We would love to bring back a proper cliff," confessed Pirelli's motorsport boss Paul Hembery. "I don't know if we have enough opportunity to get a solution that works perfectly during the Abu Dhabi test, but the ideal situation is that we have a cliff back so we can get back to two or three stops, rather than pushing the stint lengths as has been a tendency in the last few years." According to Hembery, the desired effect could be done without having to change the tyre compound, meaning other than a dramatic drop in performance towards the end of its life, the tyres would remain fundamentally the same as they are this year. "It can be chemically engineered," Hembery explained. "It is what we trying, so it becomes unbeneficial to stay out for longer stints. It means you have to come in and change. "If there is one input the teams have had, it is to get back to two or three stops rather than the predominant one stop racing we have had this year." Pirelli has a tyre test following the Abu Dhabi Grand Prix where it will evaluate things ahead of 2016, including the all-new ultrasoft compound which will be introduced into the current range next season. All ten teams will attend the test, running one car each, and will not be allowed to try new parts or change the car during the test. Pirelli will define the test programme for each car which will be fitted with unidentified tyres fitted to each car. There is also further work happening behind the scenes ahead of the 2017 season when cars are predicted to be as much as five seconds a lap faster. According to Pirelli the increased load through the tyres could pose a safety issue if it is not afforded the opportunity to test properly. "If we are talking about currently having the highest aero loads we have had, then we are already approaching levels that anyone who has been involved in F1 for the last 10-20 years has not had to face," explained Hembery. "So it is a new challenge for everybody." The problem facing the Italian company though is that, until 2017, nobody will have a car generating the sorts of forces under which the tyres will be expected to perform, making testing difficult. "We would have to imagine that testing would be based on a current car modified, because you can't ask someone to build a new car as the costs would be prohibitive," Hembery reasoned. "Then you also get to an area where who is going to build that car? Who will run it and what advantages will they get? So it becomes a never-ending issue of intrigue. "Something has to happen as it is such a big change that you cannot not do something. We cannot turn up in February before the season starts and suddenly see these things, because you have not time nor opportunity to change. "Can the sport realistically provide us in June next year a vehicle that adequately represents what the car is going to be like in 2017? That is the real question and that is the one that has not been answered." tyre cliFF set to return For 2016 LATe TO THe PARTY Lewis Hamilton arrived in Brazil 24 hours later than planned after spending an extra day recovering from illness.
