Old school sidepod panels for downforce

Recently at Monaco, Williams and Toyota added winglets inside of their sidepod panels to add a bit of central downforce to their cars. When the panels were first introduced in Formula One - by Honda in 2006 - the inside winglets were fairly standard when most teams copied the design. Today, the panels are more focused on improving airflow and generating downforce at the rear end of the car. Monaco is however a special case, where due to its low speeds, aero efficiency is less important than downforce. The winglets have been tested by both teams at Paul Ricard and are unlikely to appear again at Canada.
