The only moveable aerodynamic device permitted in F1 – after all the rest were outlawed in the wake of a number of spectacular accidents in the late 1960 – is an adjustable flap on the front wing. Another hurdle for McLaren's competitors is the fact that with monocoques now homologated for the entire season, playing catch-up will be no easy task. Red Bull team principal Christian Horner, however, acknowledges that now they need to simply shut up and get on with it.
“It was obvious from testing that they were doing something a bit different, and we just wanted to know whether it was illegal or innovative,” the first man to raise concerns about the invention is quoted as having said by ITV-F1
. “Apparently it was innovative. It's a little bit like the double-diffuser [in 2009], but there's no point bleating about it. The governing body feels it's legal, so therefore we'll all end up developing it and pursuing those kinds of derivatives.
“I think this is nowhere near the magnitude of the effect on performance that the double-diffuser had. You can see that the double-diffusers on all the cars this year are absolutely ginormous, and it's somewhat ironic that the team that introduced it now wants to get rid of it for 2011! This falls more into innovative design. It operates certainly against the intent of the regulations, but the FIA feels it is okay so that means it's an avenue that we will pursue.”
