Subsequent to the first two testing days where the single-seaters were seen, there are aerodynamic solutions for all tastes.  During these days, it has been surprising how the engineers have hurried to cover the diffusers when the single-seaters enter the boxes.  Funny, because some moments later they’re back in the racetrack and it would be difficult to run after the car to cover the diffuser, wouldn’t it?

Leaving the “funny” note aside, let’s take a look at how the aerodynamics of the seven scuderias that have been presented in these official tests at the Valencian circuit have evolved.  I must say that it’s not an analysis of the aerodynamics, but of some visible changes.

FERRARI

The engineers of the Italian ‘scuderia’ chose to change the nose and wing in a significant way.

The nose seems to be lower than last year’s increasing its descending curve, with a softened V form (below, in the photo gallery you can enlarge the picture to see in more detail.)

For 2010, Ferrari has initially chosen to include a sharp fin, similar to the one that became fashionable with Red Bull, last year.

MERCEDES

No doubt, one of the cars with more changes, if we take the Brawn GP as reference.  The nose is even lower than Ferrari’s, with less tip and more rounded.  Very similar to last year’s well-known Red Bull design.

Contrary to the rest of the scuderias, they have selected a short tail behind the air inlet over the pilot (engine’s lid).

RENAULT

Renault does not contribute with any extraordinary changes in its front, following its aerodynamic philosophy of a robust appearance, “rough” nose. It has a descending angle, but lacks the famous V shape that can be seen in other single-seaters.

Just as it finished last season, Renault uses a great sharp fin as engine lid.

MCLAREN

The MP-4 follows an evolution from its previous model, without the V shape used by Ferrari or Mercedes.  Its nose is rounded and seems higher than others,’ even though, the front double wing is wider and have joined the “sharp fin” fashion.

Peculiar interpretation of the sharp fin, since it almost finishes in the rear aileron.  However, we’re still investigating the camera options on the single-seaters.  Note that Ferrari, McLaren and Williams “have an integrated periscope.”

WILLIAMS

Aside from the periscope, its possible the single-seater with less changes of all that we have seen (a priori).  The characteristics that stand out the most are a very flat and high nose, together with a front double aileron.

Hopefully, tomorrow we’ll go to another place where we can see the rear of the car, because we’ve heard that’s the part of the single-seater with more changes.

BMW SAUBER

As you can appreciate in this photograph, aerodynamically it seems like a completely new single-seater.  A nose with little drop, and a long but mostly high “sharp fin.”

When I say ‘high’, I mean that it does not fall as other scuderias’, but it’s rather a great extension of the air intake.

TORO ROSSO

The new Toro Rosso’s nose follows the trend of its previous model with only some slight touches.  However, the rear section is the one that has had the most evolution in 2010.

The sharp fin is an innovation joining with the rear aileron of the racing car.  The idea is to transfer the most quantity of air possible to the rear aileron.  Is that a solution to get extra grip?

Awaiting to see “the revolutionary USF1″ that according to the North Americans breaks with anything ever seen, this year the scuderias have changed a great deal the exterior of the racing cars.  Enjoy the gallery.
