Renault R31 - rearward exhaust 24 July 2011

Renault tested a prototype 'Red Bull-style' rearward exhaust on Nick Heidfeld's car on Friday in Germany (see blue highlighted area and red arrow). However, as the R31 has been built around a unique forward-facing exhaust layout, the team's trial was limited to assessing the system's potential for the future, rather than evaluating it for the Nurburgring event. The car's bodywork, especially in the area in front of the rear tyres, is too wide to fully exploit the benefits of a rear-facing exhaust. After the summer break we should see a heavily updated R31 featuring new sidepods and exhausts.
