25 august 2013, Spa-Francorchamps Circuit
Over 70% of the track is taken at full throttle and over one lap the engine will have a total wide open throttle time of over 43secs, making it one of the toughest tests for the RS27. Outright power and top speed are crucial and any gains will be twice as effective in reducing lap time compared to Monaco. To compound the challenge, changes of altitude over the lap – and between corners – put the internals of the engine, particularly the lubricant systems, under considerable pressure.
