Awesome pictures, thank you

Step by step starts looking like a modern F1 car... lets hope they got enough information from the race to optimize the new updates.

HRT Spanish GP updates explained in a video, sorry but audio is in spanish. Explains the new front wing, badge boards an the new end plates.

Wow, that was really nice. I love when they do stuff like that!

Nice video.

How come making (just the manufacture of the final pieces) 5 of those bargeboards (at the 2:00 mark) costs 40K Euro? Is that realistic? They do not look that complicated.
What drives that cost up?
Is it the materials? Is there anything exotic there?
Is it the man hours? Wouldn't making 5 equal pieces cut a lot on that?
Anything else?

Windtunnel time can be anything up to euro 1000 an hour. Doesn't take long to run up a telephone number bill.

I don´t think a Formula1 standards tunnel is anything like 1000€/hour ...you are looking at higher numbers if you look at moving belt metinks.
the Midland/Spyker/FI tunnelprogramme at Fondtech was around 300k pounds sterling per month and they had a second programme in UK running ..as made public in that spygate rage with F1Malysia/Lorus/Caterham...

i dont agree, this car still look like GP2 car, and it's fast like one. i think they need start collect money for next year, and part by part making next year car. with this one they cant even be on same lvl with caterham or marrusia. from next year will see new tehnical regulations, and i see their chance in that one.

Tony explicitly said (in spanish) that the cost was not designing, not wind tunnel testing, but that AFTER wind tunnel testing they spent 40000 Euros actually manufacturing the real 5 pieces they had for the weekend.

Edit: OK, after hearing it a second time, he is actually a bit ambiguous (a hideous trait of spoken spanish!). The 40K figure might include design and wind tunnel after all.

considering the fact the gearbox is the dwarf like item of Williams 2011 the rear looks massive ..how come?
I´m pretty sure they could easily mount williams 2011 inner aero bits around engine and gearbox-no use of those for WGP anymore...

I´d think the beam wing is carry over from WGP as part of the package? it´s not...a 2011 package looking at the wishbones ..the williams layout looked different last year..
as the driveshafts are not severely inclined...the layout is 2012WGP

If one considers that chassis performance is a factor of mechanical and aero grip, a small team with a limited budget can only afford to concentrate on one area at a time. The major problem of this chassis is excessive tyre wear compounded by a tendency for snap oversteer. That's inherently a mechanical flaw, I'm not sure you can cure that with an aero solution.
HRT are lumbered with the problem of outsourced design. Holzer have no experience in F1 and HRT are engineering a car they did not design.

[marcush.]

how can you be sure the balance of the car is a design shortcoming ? they have not done any testing yet apart from the few hours they ran the cars in FPs.
´The F112 is a close brother to the two cars they campaigned before and so it is more than likely they know a fair bit of what they wanted to change (Holzer).
As for the rear ,I´d be surprised why the car should have less grip at the rear with a very very up to date rear that is mounted to a car which has super traction (williams FW34).
Maybe there is a installation stiffness issue underlying or the tub is not as stiff as needed ,yes ...but honestly speeaking I´m pretty sure thewy just have not
sorted the car yet setup wise.
I really don´t think you can devide Aero and mechanical behaviour and look at it in separate only.Aero is working from low till high speed ,obviously your need the car to change it´s behaviour from agile turnin and corner entry oversteery to quasi neutral steer as the cornering speeds get higher ...something clearly to be managed by Aero development methinks.
(with the basic mechanical design for good change of direction)

With different regulations (race distance,fuel loads..., Pedro's best lap in Barcelona is still 4 seconds faster than the faster GP2 car.
1.2 slower than the best Marussia car, and faster than Pic, who retiered early and is difficult to mach due to fuel load.

yes, but you need consider this:

GP2 engines are 4 litre v8s, 600bhp with a 6-speed gearbox
F1 engines are 2.4 litre v8s, 750bhp with a 7-speed gearbox
and, that dynamics of an F1 car are far superior. F1 cars generate more down-force, which increases corner speeds. Higher corner speeds, higher exit speeds, it all ends up to a much faster car.
