These two designs look visually quite different, but actually follow very similar concepts. The flaps sport a completely different profile on their rear edge (red arrows) but both have a vertical fin underneath (visible protruding from the rear of the flap) to divert airflow towards the sides. The...
For Brazil, BMW have adopted a rear wing profile with a double curve, bending upward at the extremities. This solution raises dowforce at the rear without a significant increase in drag, hence leaving the car's top speed unaffected on the long uphill straights of Interlagos.
In China BMW have added a small winglet suspended under the main curved flip-ups in front of the rear wheels, following the fashion introduced by Ferrari few races ago. These elements help in terms of reducing turbulence around the inner edge of the wheels and the rear bodywork close to them. This...
BMW Sauber's series of strong performances continued at Monza, the team finishing fourth and fifth. As expected, the main changes to the car were to adapt its aero package to the high-speed Italian circuit. Both front and rear wings were heavily revised, the front one sporting a single flap (lower...
At the last round in Hungary we looked at BMW updates behind the rear axle. In Turkey we look at those just in front of it. The bodywork has been lowered in the area around the engine exhausts - by about 2.5 cm - meaning the exhausts now protrude more clearly (see magnified detail). This change...
Overall downforce loads are even greater at the Hungaroring than in Monaco. Every possible piece of bodywork is finalised with this in mind and every year teams try to reduce the additional drag the changes create. On the F1.07 the usual single tail winglet on the rear crushable structure has been...
At Magny-Cours we mentioned how this new engine cover works in conjunction with the rear wing. At Silverstone, we look more deeply at the cover, which sports a dramatically elongated shark-fin profile on its top edge (red arrow). This helps to clean up the airflow directed towards the rear wing,...
Another team to introduce a revised rear wing for France, BMW Sauber's features a main profile that is completely flat across its entire width (left arrow). Its aim is to provide a good level of downforce without losing too much top speed on the straights. It works in conjuction with the modified...
BMW introduced this revised wing in France following last week's Silverstone test (it will probably be retained for the British Grand Prix, as both venues require similar aero configurations). The new design retains the squared central spoon profile, but has a completely new flap (red arrows), which...
Introduced last weekend in Canada and retained for Indianapolis, this design features a new main profile, with its leading edge noticeably raised in its central section (yellow arrow) and its outer extremities bending downwards slightly. This assembly has been designed specifically for low to medium...
The F1.07's Monaco aero package is one of the most highly developed in the paddock, even if much of it is carried over from the last round in Spain. A key part of its development here is the barge boards placed at front-axle level. These now sport a clearly visible horizontal knife-edge profile...
The BMW sports extensive changes to both front and rear wings in Barcelona. The front has a completely new main profile - highly curved with a squared spoon shape in the centre (red arrow - previous design in red circle) and a front lip that protrudes slightly upwards. The new design dramatically...
The F1.07's rear wing sported a new main profile in Malaysia, with its entry edge raised in its central section (red arrow) and its outer extremities bending slightly downwards. This configuration mainly suits the requirements of medium to high dowforce tracks like Sepang. It is likely the wing will...
The MP4-22's engine cover is particularly narrow, and in Malaysia it sported elements resembling an ice skating blade applied to either side of its rear section (red arrows show location and detail). Their function is to reduce drag by detaching the boundary layer of airflow from the very rear of...
The system adopted by BMW is similar in its basic concept to the one used by Ferrari. The supporting device (red arrow) between the bib (the front section of floor under the splitter) and the splitter endows the portion of floor closer to the ground with a certain degree of movement - enough to...
Two horizontal fins (red arrow) have been added in Melbourne, midway up the side of the chassis. Shaped almost like an Arabian sword, the fins split the airflow coming out from the front wing, diverting it towards the sidepods inlets and, to an extent, the bargeboards. More fins (green arrow) have...
At first sight the F1.07 hasn't altered much since launch, but looking at the front wing, there's a variety of small changes. The endplates (1) have lower entry edges, which curve inwards and connect to an additional upper profile. This reduces turbulence generated when the airflow hits the edge of...
