The question is: will they use Merc-style exhausts or blow them above the diffuser or near the beam wing ?
There's even a fourth chance: blow the exhaust gases away from the bodywork and try to exploit DRS and take the max downforce amount they can. I think there's a lot of potential near the rear wing this year, but obviously I'm not sure of it.
Ferrari and RBR have vanes in the exact same position.JohnsonsEvilTwin wrote:Sure thing.Diesel wrote:Please explain how McLaren's diffuser is bigger than everyone elses.
An EBD ban, would hit Mclaren's concept hard. They went to town on the diffuser and any change there would have big repercussions for them. No wonder Whitmarsh is tentative.Their rear wing sports vanes along its lower edge. Sauber also have much smaller solution on their current car. Having bodywork in this area effectively extends the diffuser sidewalls by some 30cm, which helps maximise the expansion ratio of the diffuser for more downforce. Such is the shape of the flow out of the diffuser, the bodywork needs to be vaned to allow the flow to expand.
McLaren have formed four vanes into the allowable area. For the test, the rear-pointing exhausts were lined up with these vanes, thus the exhaust flow will be routed by these vanes, accelerating flow inside the diffuser for even more downforce.
Red Bull also have these vanes as of Spain, IMO the performance they add is probably small, a tenth maybe? It certainly doesn't mean they have the "biggest" diffuser and we certainly won't be seeing McLaren rolling round at the back with HRT when the EBD is banned.JohnsonsEvilTwin wrote:An EBD ban, would hit Mclaren's concept hard.
