Engine-related problem for Webber

Mark Webber was at the wheel of the RB3 again today, with a programme that continued with evaluating a new aerodynamic package. Initial impressions are that the new developments work well, with the car seeming well balanced. However, the day's full programme was not completed as it was interrupted partly by sporadic rain and also by an engine-related problem on the first run of the day and another later in the afternoon. Their causes are currently under investigation.
