The Grand Prix of Belgium gave beginning on the day Friday
with excellent conditions meterológicas, something that allowed
four riders perform one turn of setup with the second
version of HALO, which is going to be developed and improved until his
introduction final in the competition in 2018.
however, the great novelty in the grill was Esteban Ocon, who
he made his debut as a pilot holder at the controls of the Manor, until the
past Grand Prix of Germany, had been managed by Rio Haryanto.
Nico Rosberg was the first driver to score a time of
reference (1:48:348), followed by the Ferrari. In any case,
the first few minutes of practice were used to
to establish the first comparisons of aerodynamic and tire,
waiting for the track will be in better conditions to
start the commissioning work of the car.
Fulfilled the first half hour of each session, there were only three
pilots for marking a reference time: Carlos Sainz, Marcus
Ericsson and Fernando Alonso. But soon the first two came out on to the track to begin its programme of work, being the McLaren driver was the only one not able to do so as a result of a water leak, having to dismantle the motor to find the cause. In order not to lose more time than necessary, the mechanics of McLaren they made another thrust unit so that the Spanish can participate in the second session, while seeking the fault in the previous one.
The Mercedes at the front, the Force India then
With the equator of the session already completed, Nico Rosberg retains the first place, but now followed closely by Lewis Hamilton. The Force India, who have traditionally been very competitive on this circuit, it is placed below with Sergio Pérez just over a tenth ahead of his team-mate Nico Hülkenberg.
Many were the pilots who began the tests with the pneumatic pilot of Pirelli with a reinforced structure to prevent collapse by rubbing with pianos or aggressive external elements present in the asphalt.
The last few minutes of the session were used by the pilots to continue with the evaluation work of the different compounds of tires, in addition to start the commissioning work of the second session.
The Mercedes remained at the head of the table with Nico Rosberg as the only ride in the 1:48 and with Kimi Räikkönen less than a tenth of Lewis Hamilton. Carlos Sainz finished the session fourteenth to three seconds of the Mercedes, while Esteban Ocon enjoyed a great debut with Manor to finish two positions further back than the Spanish, and with a one-second margin over his team-mate Pascal Wehrlein.
