Force India VJM03 - blown diffuser 01 August 2010

In Hungary, Force India introduced their version of the blown diffuser (see red arrow) to just one car - Adrian Sutil's. It was tested on Friday, but the team then decided to run both cars in the standard configuration for the race. With the expense of tooling the new exhausts, a dyno test for tuning the exhausts to the engine, the demand for five sets of diffusers and all the wind tunnel and Computational Fluid Dynamics (CFD) programming, it could cost up to an estimated $1.5 million to introduce.
