Williams' Pat Symonds on complex 2014 Formula 1 cars

Williams's chief technical officer Pat Symonds says getting used to the new 2014 technical specifications in F1 has been "character building".

Symonds admits there have been good and bad days in testing so far, but feels the last few days in Bahrain have gone quite well.

In regards to learning about the new engines, or "power trains", Symonds says they are very complex but is sure his team will get to grips with them quickly.
