Force India have only recently come up with their wheel fairings, but are already heavily experimenting with them. While the initial version very much resembled that of Red Bull, the Singapore circuit required modifications to make sure the front brakes are adequately cooled. The 'hot-spec' version is basically a half fairing, as it only covers half of the wheel. Due to the nature of the remaining circuits though, it appears unlikely that the team will use this version again as more... Read more

As extra little bit of downforce stripped off some time of a lap around Singapore, Toyota added a mini rear wing behind the usual one. Other teams have done similar things, but Toyota designed a wing with a slot gap. The gap is vital for such high angle of attack in order to prevent flow seperation on its underside.
The rear wing itself is of the same type as the one used at Monaco. It makes maximum use of the regulations by having 3 elements in the central area of the wing, again f... Read more

Despite Kubica's recent concern of the car's development, the pace of the BMW Sauber was relatively good. As what is probably one of the final improvements to the F1.08, the team added a little extra flipup behind the chimney. Each little bit of extra downforce is a help at the twisty corners of the Singapore street circuit.
The rear wing on the other hand did not undergo development. It is the exact same wing as the one raced at the Hungaroring, a similar high downforce circuit.

McLaren have introduced yet another step to its car, this time by changing the sidepod panel. After its initial, small shape at the time of the launch, the team quickly stretched the element - Monza spec in lower part of the image - to make use of it for most of the season. Other temporary developments were used for specific circuits, and it looks like Singapore's high downforce requirements made room for another elongation. McLaren added approximately 10cm to the item to modify air... Read more

Although tested at the latest test at Jerez, the Singapore event is the first time Red Bull will race their car with the new delta wings on it. The new wings are a mixture of the antlers on the McLaren MP4-23 and the very first ones of BMW Sauber. The approach to the design was however fairly simple as far the the wings concern. The profile is a simple, zero inclination aerofoil with a fairly high thickness. The roots of the wings on the other hand look very much inspired to the F1.08.

As one of the final developments of this year, Red Bull have changed the obligatory linkage of the bridge wing. As of the introduction of the rule, Red Bull connected the bridge wing with a simple pillar where the bridge is closest to the nose cone. At the moment this is still the case for most of the teams, including Toro Rosso. However, now they have modified the link to be identical to McLaren's version. The Woking based team used this type of link already from the first race aft... Read more

As part of their major Monza package, Honda introduced a completely new rear wing. The new wing consists of two elements with the obligatory spacer in the middle to prevent the slot gap from closing at high speeds.
There is also a cutout in the middle of the wing - alike but bigger than on the Red Bull RB4 -, similar to what can be seen on the outer sides. These items would have made the wing ideal for bending and hence reducing drag at high speeds, but since the rules do not allow ... Read more

Williams also had its updates for Monza, the most specific of which being the simplified front wing. Contrary to the rest of the races, the FW30 did not have a bridge wing because the team didn't think they needed the extra downforce and drag.
The base plane itself is based on the pre-Spa configuration, indicating that the team was already going through the development before considering the new Spa front wing. The central deep spoon was left unchanged. On the other hand, the third ... Read more

In fact, it's a quick fix for heating the car, as it reduces cooling capacity. Modern F1 cars use airflow in the sidepods to pass through the radiators in order to cool the engine. Behind the heat exchangers, most teams have shark gills in combination with a (closed) chimney to quickly allow the hot air to escape the sidepod.
While such gills are a perfect compromise between cooling capacity and drag, it is always better to have less openings if that is possible. So, Honda have quit... Read more

Ferrari's low downforce package very much resembles last year's Monza specification. In fact their new rear wing is not so new as it is identical to last year's version that was fitted on the F2007. The decision will no doubt have saved some time at Maranello, time than can well be invested in next year's car.
Also marked in the image are the modified flipups. The twin element configuration has been replaced by a single one, reducing drag and downforce - Spa configuration displayed ... Read more
