Sauber unveiled their C31 on track at Jerez, where later that day it underwent a shakedown before starting winter testing the day after that.
While the team lost its technical director James Key during the winter, it is unlikely to have played any role in the development of the C31, and will likely only affect the car of 2013. Therefore, at the launch it was Matt Morris, the team's new chief designer who was the technical head. He arrived halfway through 2011 after similar roles at Cosworth and WilliamsF1.
In its entirety, the car is an aggressive evolution of the C30, with carryovers mostly at the front of the car while the team have mainly focused to get the rear sorted out, creating narrower sidepods to allow a better airflow onto the diffuser and the beam wing. The exhausts on the Sauber are position quite forward, allowing the hot exhaust gases to get mixed with cooler air before they hit the suspension arms and the rear wing elements. The rear suspension itself meanwhile was also changed into a pullrod design, for benefits of rear airflow and lowering the car's centre of gravity.
Just like its predecessor though, the car is neat and very clean aerodynamically, the result of a car that came from a team with much less resources than any of the front running contenders. Sauber however showed before, both with the C29 as well as with the C30 that it is well capable of delivering a very decent car with a small team.
