Ferrari tried a lot of new components in Hungary on Friday, even some aero
solutions that could be useful on the 2012 car, which will have a differently shaped
cockpit. Both Fernando Alonso and Felipe Massa tested this front wing (main drawing),
which (in Red Bull style) features an additional upper-deck flap absent on the
regular configuration (inset).

Ferrari tried a lot of new components in Hungary on Friday, even some aero
solutions that could be useful on the 2012 car, which will have a differently shaped
cockpit. Both Fernando Alonso and Felipe Massa trialled this rear wing in a back-to-back
test with the configuration used previously for qualifying and the race in Germany. It has
a curved main plane (centre red arrow), where the previous one was straight, with only
three gills in the endplate (left red arrow), and different positioning of the planes relative
to the endplate (right red arrow). These endplates seem to be in Spa configuration, but
with, of course, a different, medium-downforce main plane and flap set-up.

Renault's drivers had three different front wings at their disposal on Friday in
Hungary, including one used by the team in Monaco (left circle). In the end they
chose the one shown in the main drawing for qualifying and the race. This
configuration was also used at the Nurburgring last weekend.

Red Bull used a mix of old and new front-wing solutions in Hungary. They
moved back to the original, thin wing support, in place of the newer, wide one (1),
and also reverted to the turning vanes under the nose cone (2) rather than those
attached to the lower part of the chassis which the team had been running since
Valencia. The main plane and flap (3) were new, derived from the Nurburgring configuration,
and on Friday Sebastian Vettel also tried a different flap design (4) for a few laps.

Ferrari have opted to use two different front wings for the qualifying session and
race in Belgium. Massa decided to stay with the one he used in Canada, whilst Alonso
is running with a new version. Tested in Hungary, it features Red Bull-inspired upper
flaps (red arrow), and a single main flap instead of the previous double solution.

Mercedes have brought another evolution of the front wing they introduced in
Hungary to Spa. As well as the additional upper flap, which was inspired by the Red
Bull, there is now an additional vertical fin (large red arrow) to better direct airflow. The
team have also modified the system used to adjust the flap's angle of incidence by
moving it from its previous central position (where the new fin now is) to the side
of the endplate (small red arrow).

McLaren MP4-26 - brake duct aero development
Brake ducts are ever evolving and becoming increasingly important as aerodynamic
devices. As well as attaching aero fins to the inside, teams - including McLaren - have
started to mimic the effect of the wheel rim covers seen in previous seasons (but now
banned) with complex-shaped brake ducts which better control the flow of air around
the outside of the wheel. This drawing shows the rear brake drum on the MP4-26.

Red Bull brought two different brake duct solutions to Belgium. The one
shown in the drawing was used by Sebastian Vettel. It has a sophisticated shape
similar in style to the one used by McLaren to better channel the air to the outside of
the rim.

The Toro Rosso featured a brand new nose in Belgium. Taller, flatter and
longer than the previous version, the new solution is similar to the one used by
Mercedes and will improve the airflow in the car's lower section. It passed a
crash test on 4 August.

In Monza Fernando Alonso and Felipe Massa have been using the new rear wing
Ferrari introduced at the last round at Spa. But there are some differences on the
Monza-spec wing (see main drawing), including different endplates with just two gills
instead of three (see upper red arrow and inset) and a lower downforce main profile and
flap. The beam wing (see lower red arrow) is also new. No longer straight in shape,
it's wider at its centre and has a different chord.

In Monza (see inset) Mercedes are using the same rear wing they took to
the last round in Belgium (see main drawing). However, they have opted to
use a different angle of incidence for the main plane, which now has a higher
leading edge, and the flap, which is now angled much lower.
|
|
|
|
|

|
|

At the last round in Belgium Toro Rosso brought a new nose and in Monza they
have tested a new front wing. It features a new small flap (see red arrow) to better
direct the flow of air to the back of the car. The team evaluated the new wing on
Friday but didn't opt to use it in qualifying and the race.

In Italy McLaren are using the same rear wing they introduced in Spa. It is a
touch more angled than those found on other cars, but seems to be advantageous
into and out of corners and in braking areas.

Red Bull evaluated three different front wings in Singapore on Friday. Pictured
is the one tested by Vettel and then used by both drivers during qualifying and
for the race. There is a step on the main plane (left-hand arrow). This is similar in
style to the solution introduced (but not raced) by McLaren in Spa. There is also a
new upper flap (right-hand arrow), inspired by the one McLaren used in Monza.

At the rear of cars, brake ducts have become more and more important as
downforce-boosting aerodynamic devices. The Red Bull ducts feature several small
planes on the inside of the brake drum to help enhance downforce.

McLaren are using a new exhaust layout in Singapore. Longer than the previous
version, it has been combined with a new diffuser featuring a small, Red Bull-inspired
flap in its central section.
|
|
|
|
|
|
|
|
|
|
|
|
In Singapore Ferrari have modified their exhaust layout. The final section (see
blue highlighted area) is a little narrower than before and no longer features the
small stepped section which helped to blow air both under and on the top
of the side channel.

Red Bull have devised a clever way to maintain tyre temperatures in the garage.
The FIA long ago banned systems designed to do this by heating the inside of the
wheel rim, as introduced by Toyota in Canada 2005. Since Belgium this year, however,
Red Bull have been placing a small, pre-heated aluminium cylinder (right) inside all four
brake ducts, an idea tested by Williams some years ago. The cylinder's primary function
is to heat up the brake discs, but it also stops cold discs and callipers from robbing
the blanketed tyres of valuable temperature. Just before the car leaves the garage
mechanics wearing special gloves remove the rudimentary brake duct covers
(left) and take out the cylinders.
