Halo continues to cause many headaches for engineers and drivers. This time the problem is the weight of the car. Last year drivers were trying to gain weight and increase muscle mass. This year they will have to control their weight, because their weight should not increase and some drivers may have to lose weight. The new regulation for 2018 introduces the Halo as a mandatory safety system in all cars. The Halo weighs about nine kilos, to which we must add six more to strengthen the chassis and pass the FIA crash tests. The problem is in the weight limit of the car. Last season it was 728 kg and for the next season (2018) it has only increased by six kilos, that is to say 732 kg. This situation leaves little margin for the teams to use ballast to balance the cars without talking about the problems that might have the taller and heavier drivers like Nico Hülkenberg or Lance Stroll. This situation will have the teams constantly controlling not to exceed the weight limit and the heavier drivers will be a bit slower on the track. On the other hand, drivers with less weight like Checo Pérez or Sebastian Vettel are the beneficiaries of this situation, since in this way they will be able to take advantage compare to their opponents.
While in the Ferrari team are preparing for 2018. The Maranello team overcame the frontal crash test of its first chassis next season. The chassis 669 has exceeded the values required by the FIA in the aerodynamic approval tests. The successor of the SF70H has not had problems to pass the tests, the chassis 669 of course already has the Halo. The Maranello team was the first team to pass the dynamic tests of the FIA. On February 22, the Ferrari team will present their car in Maranello, with which they will try to overtake Mercedes this season.
