HUNGARY GRAND PRIX 2005 – TECHNICAL ANALYSIS
Hungary saw Red Bull’s final major aerodynamic revisions to their RB01 machine before they switch their attentions to the detailed design process for next year’s car. Here, we see a revised engine cover, with even narrower sidepods sculpted inwards at the rear. This tighter rear-end packaging increases the overall aerodynamic efficiency of the car.
Wlliams FW27 – triple mid wing
As Budapest is a very twisty circuit, Williams adapted their aerodynamics accordingly. For the first time the FW27 sported a series of three mid wings to create additional downforce right at the centre of the car. This doesn’t cause any change to the overall aerodynamic balance, due to the central location, with no pre-eminence either to the front or rear downforce load.
Minardi PS05 – rear wing development
Minardi introduced this new design in Hockenheim and have added a small wing on top of the rear crushable structure for Hungary. The main changes are the four rounded slits in the upper-front corner of the endplates, similar to those used by other teams this season to reduce turbulence. The endplates are now narrower at the top too, with a new curving profile at the bottom. The large vertical slit – Minardi were the first to introduce this last season – remains, lessening drag and raising the efficiency of the wing’s lower profile.
Sauber have two versions of their closed sidepod chimneys. This version for Hungary has double air vents on its inner edge which still allows some hot air to escape – useful with the hot, damp weather here. It is one of a number of changes on the car for this race. Among others is an extra Gurney tab on the rear wing’s exit profile, designed to provide extra grip out of this circuit’s tight, low-speed corners.
