Renault open-minded on exhausts

Renault says that it will not be afraid to ditch the forward-facing exhaust concept that it pioneered if a new rear design proves to be better. Although the team's R31 was built around the idea of forward-facing exists to make the most of blowing air under the car, the team suspects that there could be advantages from a Red Bull Racing-style blown diffuser instead. A test of an initial design at Duxford last month provided some promising feedback on the design and, as AUTOSPORT revealed, the team is experimenting with rearward facing exhausts in practice at the Nurburgring after fitting it to Nick Heidfeld's car.
