Red Bull RB18

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Red Bull are probably dropping the rear on the straights, but not to stall the diffuser as people are saying. Just to negate extra drag of running a bit of rake. It shouldn't be a cause of their high top speed if other teams are just running their cars at that low point anyway.

If Merc and Ferrari can copy this trick and RB's top speed advantage is lost next year, they need to start improving on other areas like peak DF etc to stay competitive. Could be an exciting season next year with all 3 top teams really close.
In hopes of keeping the thread on topic, I will say that the rumored technical solution of the RB18 is not a new idea. It's one that teams have been implementing to varying levels of success for years. Previous iterations of the RB under unlimited budget never featured a solution with such effectiveness. It points to the phenomena being very complex as in that it depends not only on the suspension mechanism but also on the aero concept. A different car's diffuser may not stall at low ride height or the correct rideheight without making a mess of the cornering. A different car may be operating with a stalled diffuser and not shed as much drag as another due to the aero concept and what flows are being broken down due to the diffuser stall.
...



In this video, Kyle said it's not desirable to stall the diffuser on these 2022 cars ...
Actually, what he said is that there isn't a benefit since the cars are already running very low to the ground. This doesn't apply to the Red Bull as the Red Bull has quite a bit of ground clearance in the pitlane.

Interesting looking at the tyre degradation between the Ferrari and RB today, especially after the same number of laps.

This could have been down to the larger rear wing on the back, but typically Suzuka is a very front limited circuit, so RB played a good card there to ensure the tyre deg was in the best window.

Red Bull have this RB18 all figured out now.

V8 supercars banned this suspension in 2019 and went to a single spring solution. More specifically a control spring was introduced. But F1 being F1 this should remain legal.

F1 being F1, teams will lobby to outlaw it if one team is seen to be getting a big benefit from it.

The really interesting thing to consider is how you achieve this with torsion bars?

Especially in the days of budget caps. It was the argument used against DAS - it'll be expensive for everyone to develop their own so just outlaw it.

Rocker geometery.
Indeed. The rocker allows one to achieve a non-linear motion ratio (the ratio of the pullrod displacement to the torsion bar displacement). This can even be achieved in a conventional coil spring design without two physically different springs.

The RB18's rear suspension is a pushrod and not a pull rod.

A coil spring is actually a torsion bar when you break it down from first principles.
You can use a double torsion bar in series to get similar effect.
