Red Bull to switch to split-level diffuser

Comparing the non split-level McLaren diffuser top with the Brawn split-level diffuser bottom

The Red Bull Racing F1 Team is considering to add the controversial split-level diffuser to their 2009 car after earlier this week launching a protest against the three teams already using the device. A hearing at the International Court of Appeal on the diffusers has been set for 14 April and whether Red Bull pursues the split-level diffuser rests on that appeal.

Christian Horner said to 'BBC Sport': "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 14 April 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."
