What (besides a given wing setup) is causing the Merc so much drag? They have seemed slower on straights all year by a good margin to RBR. I gather that the RBR concept must have much less drag and Honda/Exxon probably did a bit better w/ the fuel changes, so maybe they are up 10-20hp on Merc right now but the straight-lines are much more than that. HAM was losing 0.5-0.6 on the straights today and that's been a theme all year.
I'm trying to understand what exactly was flawed as the concept (e.g. side pods) seems to emphasize low drag, yet they are forced to run a lot of wing.
- How was 'porpoising' mitigated without rising ride height? I always felt a mechanical solution e.g the J-damper/inerter made sense and I don't believe that would be illegal. Was this eliminated through changing the floor design itself to not cause oscillations, or the suspension to control them?
- What needs to change for the current concept to work next year? I'm assuming the monocoque is a key limitation
- It has been said that the optimum car design given the calendar is to create as much -L as possible at ~120mph, then emphasize -L/D (efficiency) above that. One way was said to be the 'layback' rear wing, or any number of other drag reduction systems used over the years. How is RBR so much faster on the straights?
