The reliability will be a key point in a season 2017 in which the cars are completely new and, although the thruster units keep the same line regulatory since 2014, the thorough redesign of the car has made many of the needs of cooling and packaging have been changed.
This, along with the need to complete the 20 races, with only four engines, is creating problems to some computers, who have already used their third, fourth or even fifth element in some of the cars.
it Is the case of the two McLaren drivers, who have already had to face penalties for exceeding the limit of four components. Fernando Alonso now has the fifth turbo and MGU-H (energy recovery system heat) in his car, something that Stoffel Vandoorne should also add the fifth battery of the energy storage, as well as the electronic control unit that controls the thruster unit.
But even more important is the situation of Ferrari, because their pilots are fighting for the championship and may be in trouble in front of a Mercedes that still competes with the second engine of the season. Sebastian Vettel has already premiered in Barcelona, his fourth turbo, while Kimi Räikkönen has already used the third. With 14 runs ahead, it will be complicated that none of the two incurs the penalty of ten places for the first use of a fifth unit of any of the six elements that make up the thruster units current. In the case of repeated with another element, the sum of positions on the grid will be five for every one of them.
, things are very different for the teams powered by Mercedes, because none of them has used even the third unit, and Williams not even the second. Despite the reliability problems they have had in the first races, the teams with the Renault engine are not also in trouble and only Carlos Sainz and Jolyon Palmer have mounted as the third unit of any of the elements of the motor.
