This time we will talk about Sauber,the team that taught us,that in practically any season they can get some very good results.Peter Sauber is a well known for a good drivers choice,this time there`s no problem there.Both Kamui and Serhio have shown very good results, on the track.We can expect the same this season,no doubt they will get it!
Fresh & evolutionary
Summarising all the efforts put into developing the new Sauber C31-Ferrari, Chief Designer Matt Morris says: “The C31 is revolutionary where we had fresh ideas, particularly at the rear of the car, and it is an evolution where we knew we could carry over certain approaches. We had to improve on the weaknesses we identified on the C30, but at the same time we wanted to maintain its strengths.”
The engineers opted again to go with a high chassis design. However, according to the new 2012 regulations, the nose cone needs to be lower, which is a safety requirement. As a result, the nose cone has quite a different shape to how it was in the past. The chassis itself shows absolute minimum cross sections all the way to the cockpit.
By an overall tidier design, the front suspension has been optimised for integration with the chassis and the upright. Otherwise it’s a traditional layout with a pushrod and a high-level wishbone.
Packaging was further optimised under the side pods in order to open up more aerodynamic development scope in that area. The cooling layout is based around a similar philosophy to the C30, because that proved to be effective. It helps to get the volume of the coolers forward and allows the design of very compact rear bodywork.
A familiar element of the car is the Ferrari engine, onto which an all-new carbon transmission is bolted – also supplied by Ferrari. The longitudinally mounted transmission is a very tidy, neat unit. The entire rear of the car is much more tightly packaged, helped by the gearbox design, and in addition the engineers have gone in some new directions around the floor at the back of the car. The exhaust tailpipe positions are regulated in 2012, which has had a further effect on how the bodywork design has been set out.
The rear suspension is now a pullrod design. It shows a long pullrod towards the front of the gearbox and wide angled wishbones. This design allows improved packaging of the rear spring and damper elements. Despite the change from pushrod to pullrod, in terms of kinematics the engineers maintained a similar direction to the one they went in for the C30.
Finally, Morris casts a glance at the next steps after the roll-out of the Sauber C31-Ferrari: “The current plan is to launch a fairly basic roll-out version of the car, which was defined quite some time ago. We will then be testing development parts during the upcoming weeks with a late upgrade for the first race on 18th March in Australia. Therefore the car will look quite different in Melbourne compared to the roll-out car.”
