Greetings,
This concept by redbull is nothing new. They were used in the 80s.
Why is it they we stopped being used back then?
Wasn`t it when turbos were allowed and used, the diffuser would suck the car to the ground? Why did they stop being used?

BFN?
Weal, the the 80’s concept benefited mainly from Turbo’s, teams could keep the turbos spooled up to maintain a stable exhaust flow to the exhaust. High reving engines just arn’t that stable, downforce cuts as the throttle comes off, right at the second you need it.
The last exhaust diffuser car, a Newey creation, the Mp4-18 was great for a few laps, then it set itself on fire, an it failed crash tests n stuff, I have the sneaking suspicion that a few mp4 18 ideas which technology hadn’t caught up with yet are on the RB6.
Also diffusers still suck the cars to the ground by creating low preassure under the car, opposite of the rear wing which pushes the car into the ground. Air is forced to exit and disperse at increased velocity from the diffuser, lowering the preassure under the car.
mjpowell – you’re referring to blown diffusers, not double diffusers, they’re not one and the same thing. A double diffuser could be blown but doesn’t have to be, a blown diffuser could be single, double or even triple decker.
Diffusers (blown and otherwise) have been commonplace in F1 since the banning of ground effect for 1983.
Renault were the first to route exhaust gases through the diffuser, whether they invented the overall diffuser concept I don’t know off the top of my head.
was doing some google and quickly landed on this forum post

It’s a rumor that the double diffuser (like used last year) was an idea from the super aguri team!
