Force India VJM03 - F-duct 07 November 2010
Force India were the first team to have the F-duct blowing on to the rear wing's main plane instead of the flap (blue arrow). This system was introduced in Silverstone then copied by Renault at Spa, Red Bull and BMW Sauber in Singapore, and McLaren in Japan and Korea. It's a more powerful and efficient solution. Ferrari were also expected to follow Force India's example, but chose instead to concentrate on their blown diffuser solution.
