Red Bull RB10 - 'monkey seat' 26 May 2014
Monaco is a track where you want as much downforce as possible. The tight and twisty track layout and very slippery surface mean that it is very difficult to get temperature into the tyres. As an example, tyres running at something like 60 degrees Celsius as opposed to 80 degrees can cost a driver up to a second in lap time. Downforce helps generate tyre temperature and with that in mind Red Bull have added what is called a 'monkey seat' to their rear wing set-up. This is a small wing just above the exhaust outlet, which works in conjunction with the higher speed exhaust gasses in this area. These allow it to produce more downforce, especially at low car speeds when the engine revs are high, generating more high-speed exhaust flow.
