Sauber C30 analysis – targeting mid field
Sauber had to withstand BMW departure at late 2009 and survive despite budget and sponsor deficit . Luckily the team not only managed to end the 2010 season in respect but also worked hard and presented a brand new car for 2011 season which may still be painted in white and carbon black but carries a lot more sponsor logos . The new contender for the 2011 season coded as C30 has a front zone refined in details , quite boxy and larger sidepods due to KERS reinstallation to the monocoque, a completely new rear zone and finally exhausts blowing close to the floor .
The new nose is a bit higher and has a slightly thinner nose cone tip lacking totally the small oval hole . The upper surface is now U-shaped , difference from last year flat nose , to optimise airflow over the nose .
Skirts are hanging under the nose cone just in front of the lower wishbone attachment point to the chassis to channel airflow under the nose .
The front suspension can be well regarded as a short twin keel design, in contrast to the C29 zero keel , to aid channeling the airflow under the nose alongside with the nose skirts . The steering axis is also shifted up in front of the upper wishbone in an attempt to reduce drag .
C30 front wing shows strong resemblance to the C29 Spanish front wing spec . However all teams are expected to update their wings before the first 2011 race including Sauber despite the fact that a few steps backwards were taken during last season final races regarding front wing evolution .
Around the cockpit zone little have changed , mirrors remain similar , bargeboards are copied from C29 but sidepod panels are simpler than before despite the fact that C29 raced by far more complicated panels . Possibly C30 future upgrade packages will include new more sophisticated panels .
The floor splitter is also copied directly from the C29
KERS reinstallation in the car increased C30 cooling needs and it would be no surprise to see past season cooling options being tested during winter testing .
In particular Sauber raced multiple hot air exits during 2010 on its C29 like cockpit side venting , sidepod rear bottom gills , around the periscope exhaust and an oval rear central outlet . By now C30 featured cockpit side venting and a completely different thinner rear central outlet for the hot air .
Much bodywork was removed behind the driver’s helmet so as to reduce drag as much as possible . To strengthen the roll zone the C30 has two pairs of pillars instead of a single one featured by C29 . The design of the quadruple airbox pillars is not new but was pioneered by Mc Laren a few years ago .
The airbox inlet retained its triangular shape .
KERS reinstallation and increased cooling needs because of this effected significantly mechanics view of the new sidepods structure and shape . They now stand taller and larger having larger boxy radiators inlets to feed both the engine and KERS cooling systems . Nevertheless the team managed to make them remarkably sculpted on their front section while their back is opened to let exhaust pipes exit close to the floor and get rid of the hot air .
The 2011 rules banned any connection of the engine cover to the rear wing profile thus the C30 has a more conventional engine cover derived from past years featuring not any more the shark fin . At the back there is a thin outlet to blow hot air between the rear wing flaps and beam wing .
C30 exploits also the rear wing pillar to house the flap moving mechanism with the upper section of it to be planted inside the planes to keep drag low .
Front wheels Rear wheels
Same wheel rim pattern to the C29 provided by OZ for both the front and rear wheels
Tyres : Pirelli replaced Bridgestone
Front brake external look reveals few differences from C29 late season brakes . The twin ducts are present , one to cool the carbon brake disc supplied by Brembo and another one lower to cool the six-pistons calipers and rest brake internal components .
Rear zone and suspension
C30 has a rather conventional push rod rear suspension built with extra care to keep the lower wishbones protected from the exhausts hot emissions which direct towards the diffuser central roof . The diffuser is partially detached from the rear crash structure and like Ferrari is being hold by two cables for strengthening reasons . This configuration provides a cleaner airflow towards the beam wing making it to produce extra downforce .
Ferrari supplies Sauber with its 2011 spec engine , KERS and 7 speed gearbox .
