Sauber has unveiled its 2014 C33-Ferrari Formula One race car.
The most visually striking element of the Sauber C33-Ferrari is the very low, snout-like nose. The front wing pylon’s attachments on the nose have been moved out as far as possible allowed by the regulations to channel as much air as possible under the car. Lower noses have been introduced by agreement between the FIA and the teams to reduce the risk that a car will be launched into the air in the case of a nose to rear wheel accident and also to reduce the risk of a driver injury in the event of a “T bone” accident.
The C33 aerodynamics engineers were handed a new brief for the design of the front wing, which is 7.5 centimeters narrower on either side than the previous version. This creates very different airflow conditions. The entire front wing with its complex end plates, has, therefore, been newly developed from the ground up.
The front suspension concept has changed little, with its springs and dampers again pushrod-actuated. However, the changes to the regulations regarding the chassis profile have called for some detail adjustments.
The side crash elements have had a significant influence on the form of the side pods which is clearly visible in the design of the car. The cooling air intakes are slightly larger than those of last year’s car because the cooling requirements of the power unit and ancillaries have increased considerably. For the same reason, the vertically mounted radiators are now significantly larger. Again, the engineers have built a degree of flexibility into their design to allow scope to react should requirements shift in one or other direction.
As far as the engine in particular is concerned, the changes require a completely new concept. In place of last season’s naturally aspirated 2.4-liter V-8 engine comes a 1.6-liter turbocharged V6 power unit, backed up by an energy recovery system (ERS) which is twice as powerful as in the past and with, potentially, more than ten times the deployable energy.
The cars overall will be slower due to the raising of the minimum weight, which increases from 642 kg to 691 kg.
“Together, these changes present the engineers with a huge challenge, especially with time pressure also a major factor,” said Eric Gandelin, Sauber F1 Team Chief Designer. “We’ve had to make various decisions on the chassis before all the necessary data and information was available to us. That is understandable, given that engine development continues alongside that of the rest of the car up to the last possible moment.”
The Sauber F1 Team will begin the test in Jerez with a roll-out version of the Sauber C33-Ferrari. In December, the Sauber F1 Team announced that Esteban Gutiérrez would stay on for the 2014 season, completing the Sauber driver line-up with Adrian Sutil.
