Renault to upgrade F1 wind tunnel

(GMM) Enstone based Renault is set to increase the scale size of its formula one wind tunnel.

The team's wind tunnel and rolling road currently operates with 50 per cent scale models, but the regulations allow for up to 60 per cent testing.

"We will get our wind tunnel at the 60 per cent level during the off season," team boss Eric Boullier told Auto Plus.

Renault is currently fifth in the 2010 constructors' world championship.
