Renault R26 - revised front wing

Part of a comprehensive new aero package, Renault adopted this revised front wing in Germany, with the additional upper profiles now longer and more curved, and attached directly to the nose cone, in a similar fashion to the Ferrari. This increases downforce, and losing the small vertical pillar...

Ferrari 248 F1 - additional rear flip-ups

A small but effective aero change introduced in Germany - ahead of a new rear diffuser expected at the next round in Hungary - is this extra flip-up under the main one in front of the rear wheel. This adds a significant amount of downforce close to the rear axle, providing valuable extra rear grip,...

McLaren MP4-21 - front-wing development

An evolution in Germany, which in some ways seems to be going in the opposite direction to recent developments. The wing's endplate is completely different to that at the last race. Its profile is now vertical at the top as opposed to the bottom, with the bottom, not the top, sloping outwards. And...

Williams FW28 - vertical side splitter

An interesting development in Germany is this vertical splitter just below the upwardly-curved flip-ups on the side of the car. It has two functions. Firstly it strengthens the flip-up structure. Secondly, it acts as a splitter in a crucial area, increasing the speed and pressure of the airflow...

Renault R26 - mass damper system

Not new, but the subject of much controversy in Germany, the damper takes the form of a free-moving mass inside a vertical spring. Its function is to reduce the sensitivity of the car's front end to differing load variations between high- and low-speed sections of the track, and to counteract the...

BMW Sauber F1.06 - winglets & additional turning vanes

Continuing the seemingly endless aero development of the F1.06 are some interesting changes in front of its sidepods. A new winglet (upper arrow) has been added at the front, clearly inspired by those on the Honda and Toyota, dramatically improving the continuity of airflow passing over the sidepod,...
