Mercedes F1 W05 Hybrid - 'monkey seat' 23 May 2014

One of the noticeable differences to Mercedes' F1 W05 Hybrid in Monaco was the addition of a 'monkey seat' above the exhaust outlet. This small wing section not only produces extra downforce, its performance is enhanced because the exhaust gasses that pass over it are traveling at a higher speed than the car itself. This is especially beneficial when the car is going through a low-speed corner and the engine revs are high. This is because the more rear downforce you can generate in these situations, the better traction you have exiting slow corners. Nowhere is this of more critical importance than Monaco.
