Late last year, the FIA proposed changing the rear wing on Formula One cars to reduce turbulence and help drivers get closer to one another, thus encorouging overtaking. This wing (known as Centreline Downwash Generating Wing, or CDG) – which is split in the middle and sort of hovers behind each rear wheel – has caused some controversy among F1 employees as it seemed that the FIA had done very little testing or research into the effects and therefore its effectiveness. Many technical directors felt that more should be done to address this issue, and thus a unanimous decision concluded that this – and many other changes – would now wait until 2009 before coming into effect.
Also at the meeting, it was agreed that testing would now be regulated by the mileage done (30,000km/team/year) rather than the days spent at the circuits. This makes a little more sense and can be policed a little easier. However, the regulation will not be enforced until 2008, and so it is left up to the teams to voluntarily do this should they wish in 2007.
