The first pictures of the 2017 F1 replica also offer the chance to see how new regulations have affected the car’s appearance with wider rear wheels, a lower rear wing and slimmer bodywork being immediately apparent.
The most conspicuous changes that define the Sauber C36-Ferrari due to the new regulations are:
The cars are becoming wider again, from 1.80 to 2 metres.
The tyres are 25 % wider.
The front and rear wings are becoming wider as well.
The diffuser is being enlarged.
In total, this means more downforce, more grip and, as a result, faster lap times.
Consequently, work on the concept of the new car was focused on reducing the drag coefficient (due to the wider tyres) to a minimum as well as achieving a significant weight reduction (despite the minimum weight having been raised to 728 kg), for instance by means of the new roll structure. In certain areas of lightweight design the team went to the limits. The aero concept includes the optimisation of the front and rear wings and the underfloor. The radiator, the sidepods and the bodywork were designed to be as slim as possible.
Clear progress was also achieved in terms of additional downforce. The key here is to keep downforce, which is generated via driving, and remain stable in various track sections. Jörg Zander, Technical Director, explains the changes in the development procedure in more precise terms: “We put greater emphasis on aerodynamic stability as opposed to maximising downforce.”
