I believe that the 2021 rules have a maximum length rule, or at least it is proposed.MatsNorway wrote: ↑Tue May 28, 2019 5:16 pmHow heavy is the carbon tub? and how heavy is the car? I doubt making the tub strong enough is the main reason the car is that heavy. The reason the car is that long is because it is allowed to be that heavy. Without a max length rule in the future( i am against) the cars will slowly creep up in length for aerodynamic reasons.
The tyres for 2021 are to be narrower at the front than currently, while the rears stay the same. That should mean a rearwards weight shift, if only slightly, which should make the cars shorter.
Reducing the weight limit will require more resources being spent on finding areas to reduce weight. Contrary to popular opinion, none of the cars are far enough below the weight limit to enable of strategic placement of ballast. Many struggle to get below the weight limit as it is.
