Brawn BGP001 - revised barge boards

In Brazil, Brawn introduced a new, small front bargeboard in front of the sidepod (small inset shows the previous version). The upper edge of the previous version was flat for half its length, before sloping away towards the rear. Now the upper edge drops away in distinct steps, with the previous...

Brawn BGP001 - central aero evolution

Visible changes to the Brawn are hard to spot in Japan. This middle fin (red arrow) was part of the aero package introduced in Singapore to increase downforce and improve the quality of the airflow around the central section of the car.

Brawn BGP001 - Monza-spec rear wing

Monza is the only very low-downforce track, so every team has to build a one-off aero package for this circuit. At Spa Brawn introduced a new rear wing with a new system to adjust the main plane and flap together. At Monza it is of course mounted with a lower incidence angle to the main plane. So...

Brawn BGP001 - revised front wing endplates

Brawn have been testing new front and rear wings at Spa, as well as a new Red Bull-style engine cover. On Saturday neither driver used the revised low-downforce rear wing, but this updated front wing featured on both cars. There is an additional twisted vertical fin on the outside of the endplate to...

Renault R29 - revised front wing

A new front wing for both Renaults in Valencia, with a vertical middle plate similar to that on BMW Sauber's F1.09. This helps avoid transverse airflow across the wing's main plain and inproves the quality of airflow travelling to the back of the car.

Brawn BGP001 - vertical sidepod fins

Quite a modified car from Brawn in Valencia, starting from the front wing (based on the one used in Hungary) and going back as far as the engine cover and rear wing. However, the most notable aspect is the adoption for the first time of these vertical fins in front of the side pods. A solution used...

Brawn BGP001 - 2010 front chassis development

On Friday morning at Silverstone, Jenson Button spent a few laps testing something for next year. It was an investigation into the driver's visibility when using a front chassis shape similar to the one on this year's Red Bull (inset), with raised bodywork on either side of the nose (red arrow)...

Brawn BGP001- modified front wing end plates

At Silverstone, Brawn GP modified the end plate of the new front wing introduced at the last round in Istanbul, with a wider flat area on the outside of the end plate and two little plates (red arrows) under this section. The new solution was used only on Friday, as team principal Ross Brawn stated...

Brawn BGP001 - new front wing

A new front wing for Brawn in Istanbul, with a single flap replacing the twin solution used in the first six races. The middle plate (left arrow) from where the movement of the adjustable flap (right arrow) is controlled is now shaped differently, allowing the whole flap to be moved, rather than...

Brawn BGP001 - rear floor modifications

Ever evolving, for Monaco the Brawn features new rear suspension geometry and dampers to cope better with Monte Carlo's need for more suspension travel. Retained from Barcelona is the new floor, with a cut out (1) in the middle section and an additional inlet (2) to accelerate the airflow in the...

Brawn BGP001 - revised aero package

Like most teams, Brawn introduced a new aero package in Spain, with new bodywork around the exhausts, which are now more enclosed than before (circled is the old configuration) in order to improve airflow to the rear wing. There is also a new central section to the rear diffuser (twin, as before),...

Brawn BGP001 - steering column packaging

In Spain Brawn, like many teams, introduced a new rear aero package around the exhaust exits, but it's interesting to note two other clever solutions on the Mercedes-powered car. One is the low position of the steering column (left arrow), at the same level as the front suspension's lower wishbone....

Brawn BGP001 - underslung rear brake calliper

It's not only Brawn's diffuser that is giving them speed, but a variety of clever solutions like this under-slung rear brake calliper. By mounting the calliper at the base (rather than the side) of the brake disc, Brawn have improved the overall packaging of the suspension, and lowered the centre of...

Brawn BGP001 - rear diffuser layout

These drawings illustrate the position of the two holes (bottom left drawing - highlighted in bright yellow) in the underbody of the Brawn, in the vertical section where the reference and step planes meet. These boost the efficiency of the rear diffuser, but also need careful gearbox and suspension...

Brawn BGP001 - rear diffuser design

Brawn have a quite different central channel to their diffuser, with the shape of the deformable structure being used to create a sort of double-decker (black arrows) design. However, the most important and controversial aspect is that to work properly this section of the diffuser needs to be fed by...

Brawn BGP001 - front-wing design

As well as its controversial diffuser design, the Brawn also features a very innovative front wing. Situated very low at the front, the wing boasts sophisticated endplates (1), divided into two sections to better direct the airflow (purple arrows). An inventive horizontal splitter (2) creates a kind...
