New W05 proved fast and reliable from the start and therefore multiple upgrades made their arrival very soon on the chassis, including a mini wing addition above the exhaust terminal pipe. Rival teams targeted on improving reliability instead, having minor interest to push for speed.
In the absence of a beam wing in 2014 the extra winglet is attached on the rear crash structure behind and between the double supporting wing pillars.
Marussia proceeded on a DRS activator change in 1stBahrain test . Particularly the team preferred to develop an external mechanism, contained in an aerodynamically shaped shell, to open the upper flap, in an attempt to enhance the efficiency of the movable flap to generate downforce .
Apart from the introduction of vertical twin element sidepod panel, a single short vane also appeared on the top of the sidepod, with both additions to offer better airflow management towards the rear of the car.
Force India replaced at Bahrain the twin sidepod vertical flow conditioners seen in Jerez test, with a lateral wavy winglet attached directly on cockpit side. Flow management above the sidepod is not only crucial in terms of lift reduction but also for rear end aero efficiency. Speaking for VJM07 rear end , Force India designers choose for narrower sidepod tail openings, favoring a huge engine funnel to balance the cooling needs, in an attempt to keep a slim and a smoother flow transition around the gearbox zone.
Caterham tested a rear wing lacking the DRS external activator but in Bahrain a fully operational DRS rear wing was put under test. Another notice is that the flaps had a reversed color theme from Jerez spec, flaps now in white with black colored logo. Endplates were also colored from black to green .
The MP4/29 carried on the nose a visually anesthetically protuberance ,which contained a data collector of significant importance. That collector is connected to numerous sensors via cables, also visible on the nose surface . Such devices transform the real car performance into useful numeric track data that can be contrasted with theoretically exported data . A strong correlation between the two data sources clears the path for the next upgrade step .
The team also applied additional data collectors housed inside aerodynamically shaped carapaces on both endplates of the rear wing .
Cooling efficiency is of special attendance in 2014 , thus Williams did not neglect to design and construct an extra cooling inlet inside the main sidepod tunnel.
