Red Bull Racing yesterday admitted that they are looking into adding the controversial diffuser to their RB5—the very diffuser that they, alongside Ferrari, lodged a protest against just four days ago.
At present, seven teams, including RBR, are using a single outlet diffuser—basically a modified version of the 2008 diffusers.
However, RAR's team principal, Christian Horner, told the BBC: "We started to look at the concept several weeks ago when we saw the cars run for the first time.
"If the design is fully legal after April 14 then the seven teams will have to explore development in that area. We will accept the decision but would like to have absolute clarity going forward."
Earlier in the week I reported that McLaren had not joined the protest against Brawn GP, Williams, and Toyota, and this remains the case because RBR aren't the only ones getting in on the double-deck diffuser action.
Let's be honest, McLaren need to pull something out of the bag. Should they decide to use a new diffuser, we will see exactly how much difference it makes to a car and whether it does help transfer the power onto the track.
A hearing at the International Court of Appeal regarding the diffusers has been set for April 14, and Red Bull's pursuit of the split-level diffuser rests on that decision.
If the appeal is denied then I can see all the teams following suit, and because McLaren have already admitted to having looked at the new diffusers, they may just get theirs on first.
