2009: Goodbye to shark gills
In the winter series developments we'll be looking at the changes incurred by the drastic regulation changes that rule Formula One for 2009 and beyond. First off it marks the end of the shark gills, which came widely into use after the sidepod of the championship winning Renault R25 was completely covered with these hot air exhausts.
While they have caused interesting point of view into the car's cooling, any opening in almost the entire sidepod area is banned with article 3.8.5, except for anything less than 55mm ahead of the rear wheel centre line.
The teams will therefore have to resort to completely different cooling solutions by guiding all hot air within the sidepod towards the rear end. Such solution will surely be less effective and cause more problems with overheating at the rear.
which absolutely helps with the proposed 3 race engine rule ;)
