4. Austria will host two races seven days apart. There will also be two consecutive races at Silverstone at the start of August. Maybe there will be two races in Bahrain at the beginning of December too, if more grands prix are still needed to hit the minimum of 16 to 18 that the FIA and Formula 1 are keen to host, in order to guarantee a meaningful world championship this year. This sort of thing has never been seen in 70 years of Formula 1. Grand Prix weekends are normally run according to a very set timetable: four hours of free practice between Friday and Saturday morning and then qualifying on Saturday afternoon before the race on Sunday, without being able to adjust the car in between due to the parc fermé regulations. Now, things will be a little different, with the races coming thick and fast. The smallest intuition, or even a piece of interesting data that emerges from one race to the next, could turn out to be vital one week later. Because of that, or different weather conditions, each of the two races held at the same circuits might be very different indeed. At Silverstone, for example, Pirelli will nominate different tyres for races four and five of this year’s championship. During the first weekend (2 August) the hardest range of tyres will be available: C1, C2 and C3 ¬– from hardest to softest. The following weekend, the nomination will be one step softer: C2, C3 and C4. Silverstone is one of the three toughest circuits on tyres thanks to its fast corners and high downforce loads. As a result, we normally see quite a conservative tyre choice there: C1 C2, and C3. But Silverstone in August with the C4 as the softest tyre available (the same as Spielberg and Hungary, where lateral loads and stresses on tyres are much less) will be quite a challenge.
