They are not making the tub longer, the tub ends where it mates to the front of the PU. Like I just explained, pretty much every car on the grid has the same length tub. The biggest weight increase to the tub is from the increased load requirements required from the halo. Yes the tub weight has also increased because of the increased mass and forces from the heavier tires and increased g forces, but that is minimal in comparison.MatsNorway wrote: ↑Sun Jun 09, 2019 12:44 pmHow heavy is the tub then? it is clean carbon. 100kg?
bigger wheels ++ add extra torque to the tub. Tub needs to be stiffer/stronger but yet they make them longer and longer. Because they can. They are still below the weight limit with the giant cars they have. Once they actually struggle to make the weight they will make them shorter. including gearboxes. Mercedes had the most efficient engine and probably still do.. so it is no surprise that they had or perhaps still have the longest car. Their radiators are smaller, fuel tank is smaller, probably have some of the best electrical components too so naturally they can squeeze out a longer car within the weight limit.
I'm not sure if any of the cars are under weight, but lowering the weight limit will not force them to get shorter because the extra length of the cars does not make them heavier. The cars are longer to increase the surface area of the floor for increased downforce. The only real way to shorten the cars is to limit the wheelbase and overhangs, unfortunately.
