The Mercedes continues to experiment: test in Barcelona has seen a front wing is identical in form to that which was used in the Spanish GP Lewis Hamilton won Sunday. The difference was only in the arrangement of the ballast : look at the neutral central profile which now has the "flaps" the largest and most advanced of which are hidden under the cakes of tungsten . On W05 , then, the engineers at Brackley would have arrived at the limit of the distribution front of the weights (the FIA rules, in fact, requires a minimum of 314 kg on the front and 369 on the back, having 9 kg to move ... to find the best balance.) The image shows that the weight has been moved on the front , perhaps to avoid oversteer which just Lewis had complained in the final laps of Sunday's race (which had resolved with a stiffer rear differential). The modification imposes a greater load of the front wing (to avoid generating understeer, but allows to download slightly back, favoring a greater maximum speed.
