Sauber has also unveiled their C30 2011 Formula 1 car in Valencia, with drivers Kamui Kobayashi and Sergio Perez lifting the covers off the new monopost which according to Technical Director, James Key, has eliminated the weak points of the previous C29.
The Sauber C30 2011 F1 car features a KERS system and engine provided by Ferrari, and has the same high nose as the other race cars just unveiled for 2011.
Besides refining the front aerodynamics, the Sauber C30 2011 F1 car is also compliant with the new regulations which prevent the use of the diffuser, with James Key also mentioning that the new car is "substantially predictable and with good margins of flexibility".
