BMW Sauber have adopted a revised front wing assembly for the Japan and China races. The wing's main profile features a new lip, which protrudes to the rear. Visible thanks to its natural carbon fibre colour, this lip extends about 20mm under the flap entry edge (see yellow arrow and inset)....
Both the nosecone and front wing on the BMW were modified for the high-speed Italian Grand Prix. The nosecone pillars had a new profile, the leading edge sloping forwards (inset) rather than backwards, and the height of the pillars was reduced, thanks to the front wing's central spoon profile all...
Like Honda, BMW Sauber have introduced in Germany a couple of horizontal rectangular winglets on the top edge of the F1.08's chassis (red arrow) just in front of the cockpit. These work in conjunction with BMW's distinctive delta winglets further down the nosecone. The air passing over the car from...
In France, the F1.08 once again featured its distinctive 'boomerang' winglets and also sported a revised front wing. In comparison to its previous incarnation in Montreal (see area highlighted red), the depth of the wing's upper flap was widened at the centre (see area highlighted yellow). The team...
Canada isn't considered a special track in terms of set-up, but for the first time this season BMW Sauber have dropped the distinctive 'boomerang' winglets on the F1.08's nose (yellow dotted line shows their previous position). They have been removed to aid top speed, particularly on the long final...
Although only a small development, BMW's introduction of long vertical fences (yellow detail) under the F1.08's front wing is interesting to note and similar to a solution introduced in 2007. In addition a horizontal winglet has been placed on the rear section of the fence towards its upper edge....
Since last season it seems most teams have found from their wind tunnel and CFD (Computational Fluid Dynamics) aerodynamic testing that elongating the engine cover provides clear advantages in terms of rear-wing efficiency. By improving the quality of airflow directed towards the rear wing, the fin...
As Sakhir is a medium-to-fast track, it is important to minimise the drag generated by the various aerodynamic surfaces impacting the airflow passing over the car. Even the smallest parts can produce drag that affects a car's straight-line performance, hence BMW Sauber's changes to the barge boards...
At the start of the season teams are always eager to get a close look at their rivals' cars and discover how their design concepts have been translated into reality. After its blistering start to the year, the BMW's secrets have come in for particular scrutiny. This car is, without doubt, very...
This solution (circled) was the first aero development the team applied to the car, even before the 'delta winglets' were added on the nose, and remains an important part of the car's basic aero package, after both wind tunnel results and CFD calculations confirmed its importance in increasing the...
This is, without doubt, one of the most radical solutions seen so far in 2008 and was introduced by BMW Sauber to try to optimise the F1.08's balance. The solution provides a better quality of airflow to the car's sidepod inlets and rear end, without generating a noticeable amount of downforce. The...
Since its launch in January, the F1.08 has featured an interesting new addition in the form of a profiled winglet connected to the engine cover (red arrow). It is a development of a winglet previously placed at rear-axle level, but now moved forward to improve the F1.08's balance by helping to avoid...
It is interesting to note how all teams have transformed the front of their 2008 cars. To reduce drag generated by the pillars which connect the nose to the front wing, BMW Sauber(right) have adopted a similar solution to the one introduced by McLaren on the MP4-22 last year (left). Instead of...
