MERCEDES CLEANS UP ITS EXIT
Compared to Ferrari, the extraction of oil vapours from the Mercedes in Barcelona seemed very sketchy. In Australia, the plastic tube of the W09 has been replaced by a carbon pipe, better finished and more rigid (compare yellow arrows).
This season, the regulations mandate the evacuation of excess oil from the back of the car. On the SF71H, a tube passes into the deformable structure extending the transmission and exits at the very rear of the car. On the Mercedes, however, the tube is closer to the exhaut so that the oil evaporates on contact with hot gases. On the Force India, the extraction pipe - also attached to the carbon gearbox casing - is shorter than on the Silver Arrow.
