I think TrailGumby alluded better, that lower car mass reduces work for sticky tires to do, as well as suspension, not to mention reducing adverse forces on steering.human909 wrote: Reducing the car weight is primarily about acceleration. When you get down to the weight, the soft STICKY tyres of a F1 car and the low pressures, the other cohesive forces come more into play.
What remains to be elucidated is whether a cyclist can find a position on the bike that significantly increases downforce.
