They finally made it, a real front wing endplate
Ever since the beginning of the season, actually even during winter testing, BMW Sauber have been running extremely bulky and simple front wing endplates. At first we thought they were just for testing purposes, but the items stayed there far too long, until the Singapore GP.
There, the F1.09 was raced with a far more complex endplate, much resembling the Brawn GP and Force India versions. The combination of two panels with a separate vertical element to support the stacked elements helps divert air around the front wheels while not spilling too much air flowing over the top of the wing.
