2009 Turkish Grand Prix updates - Technical Analysis

Turkish Grand Prix BMW update double decker diffuser

BMW-Sauber is the penultimate team to introduce the double-diffuser. Thus, the two Toro Rosso are in Istanbul, the only cars without this rear floor downforce generator. The exterior of the BMW version reminds of Brawn GP’s model. In the central part of the construction the air channel is clearly visible. In comparison, the channel ends significantly further ahead and is barely visible on Red Bull’s and Ferrari’s diffusers.

Toyota rear wing slits

Toyota also introduced an interesting change to watch at the rear of their car. The rear wing end plates are now following the example of Red Bull, being pulled far down. In addition, there are striking slits at the bottom; the end plates appear to be frayed. One can only speculate on the precise impact of this change. Normally, wing slits clean the air flow, and avoid the formation of vortices. How much the changes in this area will really help, only the lap times will tell.
