Toro Rosso STR7 – Three rear wing specs so far !

      Red Bull genes are also found  within Toro Rosso’s DNA , not though in speed but mostly  in development rate . Till the Chinese GP three rear wing specs were raced/tested as shown in the images above. The Chinese spec was also  tested at Jerez on February and has a main flap with a bending upwards profile in its middle section to emphasize downforce production close to the endplates zone . Malaysian/Australian spec instead has the opposite philosophy on downforce production  featuring a bending downwards profile in the middle section . At Barcelona on March a mini plane was added on the beam wing  to increase downforce and  remains traditionally a good option for high downforce tracks like Monaco , Hungary and Singapore


Sauber C31 – Rear beam wing

February 24, 2012 2 comments

       Exhaust blown diffuser ban had a big negative impact on rear downforce production . Thus Sauber optimized as possible the rear zone  to gain some of the lost rear grip by making the rear zone even tighter and shorter  . One element that was redesigned carefully is the beam wing which has a more aggressive attack angle . That alone pushed the team to develop top mountings (in yellow) to clean from airflow disruption the lower pressure undersurface of the wing which is more sensitive and crucial for downforce production .The Sauber C30 of last season  had a more conventional configuration with the beam plane being connected from its under surface onto the top of the rear structure . Williams had last season an even more radical approach , a central mount-less beam wing which was only attached on the endplates .

      Top mountings is not something new and are already seen on other forms of racing and also on Marussia Virgin’s car the previous  season .



Lotus Renault R31 – A step backward

In Malaysia R31 reverted back to the  beam wing version with the lower arched centre zone , which was tested before season starts  . In Australia the R31 chose to race with a taller design to maximize downforce production .
