The start of a new era in Australia
Some info about track, tyres, weather conditions, rules, etc.
The Albert Park circuit is a semi-permanent track: always “green” and dirty at the beginning of the weekend,
Due to its shape it presents:
- Hard acceleration and braking: longitudinal forces are greater than lateral ones.
- Lots of slow corners: emphasis on mechanical grip and high downforce.
- Left-rear tyre is worked hardest.
Anything can happen with the weather: we can see in few minutes the switch from bright sunshine to torrential rain. The asphalt is reasonably smooth so tyre wear and degradation is comparatively low.
In 2017 Pirelli takes the ultrasoft compound to Australia for the first time. Moreover there are new rules governing race starts (where the drivers will have more clutch control) and re-starts after safety cars in wet conditions (from the grid).
From Australia to Spain, teams will have identical tyre allocations: seven sets of the softest compound available, four sets of the middle compound, and two of the hardest compound. In Australia, these are ultrasoft, supersoft and soft.
Starting from Monaco race, usual rules will be applied: teams will select 10 sets of the 13 available. Pirelli will communicate the selections on the Tuesday, 10 days before the race.
Hard work for the brakes.
The cars of F1 2017 have wider tires and more downforce, so the work of the brakes begin harder. Brembo, supplier of many F1 teams, released some interesting info about GP of Australia: the hardest braking point is before corner three. The speed has to slow down from 312 km/h to 93 km/h, on 110 meters in just 1”3 seconds. The divers suffer deceleration of 4.8g and have to use 163kg of energy on the brake pedal.
