Questionable weather typically plagues the Formula One British Grand Prix, which is held each year at the legendary Silverstone Circuit in central England, but this year conditions are looking fine. The temperature should peak at about 75 degrees F (24 degrees C) on Sunday and the skies should remain only partly cloudy throughout the weekend.

Managing tire temperatures is one of the most difficult aspects of the British Grand Prix, because the weather can change unexpectedly, and it’s a challenge to keep them consistent. Teams will need to be prepared for everything and think about how to get the maximum out of their tires during the weekend as a whole, rather than just session-by-session.

For the weekend, Pirelli has nominated its two hardest compounds: medium and hard. This is mostly due to the high forces subjected to the tires in the many high-speed corners.  We should be seeing between one and two pit stops, especially if the weather stays warm.

Going into tomorrow’s qualifying session and Sunday’s race, Mercedes AMG’s Lewis Hamilton leads the 2015 Drivers’ Championship with 169 points, though his teammate Nico Rosberg is only 10 points behind. Ferrari’s Sebastian Vettel is third with 120 points. In the Constructors’ Championship, Mercedes has 328 points to Ferrari’s 192 and Williams’ 129.

In an interesting turn of events, some rule changes have been implemented following the recent meeting of the Formula One Strategy Group. McLaren will be allowed to use a new power unit without penalty (they were penalized at the previous race in Austria for already using a fifth unit). The revised rules grant an extra unit for new manufacturers entering F1, with the change being applied retroactively to Honda, which returned this year as a power unit supplier to McLaren.

For future seasons, exhaust systems will be modified to improve the noise of the cars starting from 2016, and there will be increased restrictions on driver aids. The Formula One Strategy Group is also looking to modify the rules to create more aggressive looking cars with improved downforce. These design rules are currently being assessed by the teams with an aim for implementation by 2017.
