Marussia brought a common aero feature for the high downforce Monaco circuit, a small winglet located on the central zone of the beam wing .
At Monaco Karthikeyan only raced a rear wing having a mini plane on the beam wing (yellow arrow) for extra downforce . Furthermore “THESSAN” sponsorship logo was added on the endplates .
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
In Australia Sauber drivers preferred to race with different car set up and different wing specs . Kobayashi raced with the higher downforce launch front wing spec and the additional beam mini plane that guarantee a more stable car especially when braking late , something suitable to Kobayashi’s driving style and his appeal of overtaking . On the contrary Perez raced with the lower downforce front wing , that was first seen at Jerez on February, having also the beam mini plane removed , a configuration more appropriate to his “velvet” driving style which is to prioritize conservation of tires in good condition . The later is reflected on Perez different pit stop strategy to Kobayashi .
Pit stop strategy
|Sergio Perez||Medium -Lap24 ,||Soft –Lap 34|
|Kamui Kobayashi||Soft –Lap 13 ,||Soft –Lap 23 ,||Medium –Lap 22|
Lastly Australian rainy weather was not enough and Sauber run both cars having the large engine cover funnel .
