Watching the Ferrari following the RedBull through the chicane shows up a stark difference between the two.
The bump at the second apex caused the Ferrari to bounce fairly violently, suggesting that they have very stiff springs fitted; the RedBull, however, seemed to absorb the bump very equally across the whole rear of the car. We have seen images of the RedBull rear suspension, it features a fairly spectacular anti-roll bar, and the behaviour exhibited by the car backs this up.
The Racecar Engineering interview with Adrian Newey brings up the topic of the cars being particularly front limited this year, and that he was very involved with the suspension design. Tightening up the roll at the rear of the car should help to balance out that front limited behaviour.
It is almost as though they have created something that behaves like a De-Dion system at the rear of the car, but within the regulations regarding suspension construction.
The very tight ARB, coupled with comparatively low spring rates, is a fairly ‘out of the box’ direction to take.
Coupled with the multi-link front suspension, with what seems to be an upper leaf spring with two pivot locations, they have a second ‘out of the box’ solution.
You could say that they seem to have come up with a new way to create an old (supposedly out of date) solution, but it seems to really work well for them.
They are also apparently using Multimatic spool valve technology in their dampers.
Do you mean this valve?
It sounds fantastic! Could control rebound even in high loads and has a lot of tuning setups!
