Once again, the constructors of the Formula One World Championship stayed at the track after a Grand Prix for an in-season test. For the final in-season test, Formula One stayed home for a couple of days for some running at Silverstone. It was the final time during the season that the teams would get track time outside of race weekends so who would be quickest?

Day 1 (July 8)

As often seems to be the case in testing, it was Williams who was fastest with Felipe Massa topping the charts on Day One. After a rough race for the Brazilian, he’s showing that he still has some speed which is needed after the last few races in which teammate Bottas is outpacing.

The big surprise of the day was the pace of the Marussia of Jules Bianchi who was only nine-tenths off the pace and completed over two race distances during the day. Granted, his day ended early when the engine expired but a little bit of luck could see this team in the points again before season’s end.

1. Felipe Massa – Williams-Mercedes – 1:35.242
2. Daniel Ricciardo – Red Bull-Renault – 1:35.248
3. Nico Rosberg – Mercedes – 1:35.573
4. Adrian Sutil – Sauber-Ferrari – 1:35.674
5. Jules Bianchi – Marussia-Ferrari – 1:36.148
6. Stoffel Vandoorne – McLaren-Mercedes – 1:36.462
7. Sergio Perez – Force India-Mercedes – 1:36.583
8. Jean-Eric Vergne – Toro Rosso-Renault – 1:36.688
9. Pastor Maldonado – Lotus-Renault – 1:37.131
10. Pedro de la Rosa – Ferrari – 1:37.988
11. Will Stevens – Caterham-Renault – 1:40.627

Day 2 (July 9)

The second day of the test saw a few interesting tidbits of information for those prognosticating the future. First, with Kimi Raikkonen recovering from his hard hit at the start of the British Grand Prix, Jules Bianchi was drafted in as a substitute. The Ferrari development driver and Marussia race driver took full advantage of the opportunity by going top of the charts.

The other story of the day was Lotus running Pirelli’s new 18-inch low-profile tyres. F1 currently runs on 13-inch wheels with large sidewall tyres. The new tyres don’t really change the look of the car apart from the tyres themselves. The wheel and sidewalls look to be about the same size as the current configuration while improving the road relevance of tyres, according to Pirelli.

The day wasn’t smooth sailing for the two teams battling for 10th in the Constructors’ Championship. Caterham had a problem with their ERS system that prevented them from running Rio Haryanto as the third driver in their makeshift Young Drivers Test. Sauber’s day was more expensive as Giedo van der Garde put the car in the barrier so hard that it had to be replaced and the session had to be ended early.

1. Jules Bianchi – Ferrari – 1:35.262
2. Daniil Kvyat – Toro Rosso-Renault – 1:35.544
3. Kevin Magnussen – McLaren-Mercedes – 1:35.593
4. Giedo van der Garde – Sauber-Ferrari – 1:36.327
5. Lewis Hamilton – Mercedes – 1:36.680
6. Valtteri Bottas – Williams-Mercedes – 1:37.193
7. Max Chilton – Marussia-Ferrari – 1:37.359
8. Daniel Juncadella – Force India-Mercedes – 1:37.449
9. Sebastian Vettel – Red Bull-Renault – 1:39.410
10. Charles Pic – Lotus-Renault – 1:41.906
11. Julian Leal – Caterham-Renault – 1:42.635
