To add to that, rich teams are/were able to design they chassis a bit lighter because they were only ran for a third of the GP’s. Smaller teams needed to have a bit beefier cars to withstand a whole season (and multiple rebounding of the inserts of suspension, etc). This can make a few kg of difference.JordanMugen wrote: ↑19 Jun 2021, 14:34I guess historically, F1 teams could afford to build 5-6 chassis per season, so they would want to use the first prototype only for testing, and then wheel out models with refinements during the mid-season. Therefore Mercedes have as many as six carryover W10 chassis for this Grand Prix season.El Scorchio wrote: ↑19 Jun 2021, 12:18I find it quite weird they don’t use the same one every race. You’d think the drivers would want that, even just psychologically.
However under the budget cap, one suspects Grand Prix teams will be more prudent and only build three chassis (and perhaps commission a second spare if one of the initial cars is written-off). After all, Formula 2 chassis are used for many, many seasons in a category where cost-saving is a far higher priority.
