D he racetrack with the shortest lap time is usually also a place of the tight gaps. But the first day of training in Sao Paulo could not confirm this finding. In the first training session, Lewis Hamilton flew Sebastian Vettel's Ferrari with a lead of 0.625 seconds.

Modified front suspension at Mercedes

Mercedes then used an experimental car that already had an advance on the 2016 season. The AMGW06 was equipped with a modified front suspension and a dent on the chassis for aero tests.

In the afternoon the Silver Arrows were even more dominant. Since they drove again in their racing specification. Nico Rosberg outclassed Vettel by 0.960 seconds. On the other hand, there were only 1.427 seconds between Vettel and Marcus Ericsson in 17th place.

The old Interlagos rule of a compact field applied here. Rosberg also ranked well ahead of his teammate in the second training session. 'Lewis drove a different engine mode than I did,' said the front runner.

New Renault V6 stronger, but not strong enough

The Mercedes drivers were also on the soft run in the long run Tires faster than the hard ones. In the case of Rosberg, however, there were only two tenths between the two Pirelli sets in the seven-round comparison. That was not the case with all drivers. Carlos Sainz and Daniel Ricciardo put the faster long runs on the medium mix on the track. The reason for this was the grain of the soft tires. The upper rubber layer quickly peeled off on the green track.

Red Bull advisor Helmut Marko warned against interpreting too much into the endurance runs. 'There was a lot of traffic on the track, which made it difficult to do constant laps. Our racing simulations were subject to various handicaps. Ricciardo had to interrupt because of Alonso's engine failure, and Kvyat got into a rainy phase.' And how did the new Renault engine feel? Terse comment from the driver: 'Stronger, but not strong enough.'

Ferrari preserves the tires

While most drivers did their long runs on both types of tires, Ferrari split the work. Sebastian Vettel drove 17 laps with the soft tire compound, Kimi Räikkönen 22 with the harder tire type. Vettel made a strong impression. He achieved times of 1.17.338 and 1.17.928 in the 15th and 16th cycleMinutes.

Valtteri Bottas was on average 7 laps ahead of Vettel with the soft tires, but the Finn immediately turned into the pit lane. Team mate Felipe Massa drove 13 laps with the soft tires. The last three laps were beyond the 1.18 mark. The Brazilian complained of poor traction. 'The car just slips around on the rear axle.' Conclusion: The Williams can be dangerous to Ferrari in training, but not in the race.

Lotus returned from oblivion

A similar picture emerged with Toro Rosso. Max Verstappen and Carlos Sainz looked strong for the first 7 laps, but then the rear tires began to wear off. Force India was slower overall, but more consistent. Nico Hülkenberg was still not satisfied: 'There are still question marks. We have to understand the tires better.'

Lotus returned from oblivion. Romain Grosjean indicated with his average of 1.17.613 minutes over 7 laps that he could be a candidate for the top 6 in the race. His times in the 14-lap stint fluctuated between 1.16.908 and 1.18.819 minutes, so they were fairly constant. Important in the battle between Lotus and Toro Rosso for 6th place in the Constructors' Championship.

Sauber also made a better impression than last. Both drivers reeled their long runs on the hard tires. Felipe Nasr lost two tenths on his fastest lap because Fernando Alonso rolled out in front of him with an engine problem. Honda will change the engine. Power source number 10 returns to the McLaren. Alonso remains unpunished. Unless another drama happens on Saturday.

Pirelli and the teams expect a two-stop race despite the usual high level of tire wear and tear. Last year, winner Rosberg drove the distance with two stops.

Long run analysis training GP Brazil

Since this year we have been offering you an even better long run service. In the table below we compare two long runs. The longest in each case, and then extracted from this the average of a minimum number of laps that each driver has covered.

In Interlagos that was 7 laps each for the medium tire and for the soft set. This value is more representative of the speed of the car under racing conditions, since the degradation of the tires relates to the same number of laps. You can find it in the first column. We will also supply you with the type of tire used in the racing simulation.
