Ferrari F138 - revised diffuser 27 July 2013

On Friday morning in Hungary Felipe Massa sampled a new diffuser, featuring a different section to the outside of its side channels (see main drawing). Ending with a 45-degree cut, like the solution introduced by Lotus in 2012 (see left-hand inset), a similar layout has also been brought to Budapest by Red Bull. Although Ferrari opted to qualify and race with their old solution (see right-hand inset), Red Bull decided to use their new diffuser on the RB9 throughout the weekend.
