GP Week : Issue 56
> F1NEWS> Technical Update: Round 9 Hungary The final race before the brief Summer break proved interesting, with many teams introducing refinements, some destined for inclusion on 2010 cars. 1 – McLaren revised bodywork McLaren completed the update of its aero package, started two weeks ago in Germany. This time the rear bodywork was the focus of deep development – in particular the rear section of the sidepods, which now feature a vertical side, instead of the curved inwards previous version, and a flat top edge. In particular, the exhaust vents now are at the same level as the top of the sidepods, not protruding outside any longer.This package proved to be very efficient on this track, completing the overall aero development. The new bodywork increased the efficiency of the new undertray introduced a fortnight ago. 2 – Ferrari F60 rear bodywork Ferrari introduced some detail changes to its car – not big ones, but significant, especially in light of ensuring reliability. The top section of the engine cover of both cars featured two long and wide vents whose function was to better dissipate the heat from the engine. This was done in relation to the usually high temperatures at this time of the year in Budapest. 3 – Toyota front wing Toyota introduced here a revised front wing, differing from the previous version in the endplates. These elements now featuring, similarly to McLaren, a new curved outwards shape, sport a very interesting knife edged profile, with the outermost section slightly inclined downwards, and featuring an horizontal slit throughout all its length. This slit helps in terms of diverting the turbulence generated in this area outwards, and also reduces the sensitivity of the wing to the variations of ride heights. 4 – STR4 nose update The most evident difference on the ‘B-spec’ STR4, introduced two weeks ago, is the much wider and flatter nose common to its sister car the RB5. In the bottom line close to the tip of the nose the TV cameras are integrated in a sort of wing profile. On the side of the nose is also integrated a sort of gurney tab, very similar to the one adopted on the Brawn BGP 001. All these changes, as on the RB5, are aimed to improve the overall balance of the car. 12 4 1 2 3
