Great shots! She looks good to me. I am somewhat optimistic given their mileage and what they have admitted to focussing on. They aren't exactly standing about in the aero department either. I really wish I could make it to COTA this year. I had a great time last year.

Thanks again for the added eye candy Spyderman.

Aero and hybrid are the Toyota strong point´s… but porsche will have the best engine :-)

Let´s hope they could manage the tires better :-)

Which is a bit surprising BTW.

EDIT: front-diffuser exits are apparently still there, just behind the 919 number plate.

[Spyderman]

I suspect that they may have been doing the first tests of the low-DF package.

Always a pleasure.

Correct, save the picture edit the brightness and contrast and it will reveal the opening. It begins at the end of the number plate as said, different looking to last years.

I would upload my image I've edited, but I can't upload onto the thread, disabled apparently?

[Spyderman]

I think CyberMotor may be referring to the " shark gill-like" planes that make up the side diffusers.
This package still has holes, but no gill like planes.

[Bandicoot17]

They were using them at Bahrain so I assume they were testing a different aero configuration

[Spyderman]

...and I suspect we will see them back again during the Prologue.

Indecently: It seems Porsche tested through the night. Most likely a Le Mans simulation.

Thanks. Yes, that is what I was referencing.

In the debate between white and black cars, this is an excellent example of why I don't like black cars. You can not see the details like this.

[Spyderman]

Not long now before you will see it in white.

I think this year the teams figured out that leaving cars in black carbon fiber is as effective in hiding shapes as their elaborate camouflages were last year.

I am not sure if you are joking or not, but I actually believe that is true. I think the dazzle stuff is mostly a repeating graphic. Take a predictable pattern, wrap it on a three dimensional object and with enough photos from enough angles, I suspect you could potentially generate a decent 3d model. Its one step away from painting a grid on it! So a flat black surface probably does hide more. It also saves time on the vinyl wrap.

Efficiently moving the air over and around the car.

[Spyderman]

6000Km completed and a final 200Km to go. A real endurance test.
Thanks to Brendon Hartley for the information.

[Spyderman]

nice pictures of testing.

I for one would like to know what class they will be running in. Have they decided to really focus on a 17th Le Mans victory despite their supposed aim of a podium result? I realize how silly what I just said must sound, as they obviously wanted to win in 2014 but perhaps after a year of experience under their belts they will now adapt a differing strategy. We can see that they are obviously in a much stronger position this early on in that they have different aero packages.

[Spyderman]

Porsche will continue race simulations at Paul Ricard and will stay on until the Prologue.

German magazine "Pitwalk" has a quite good article on the Porsche 919 Hybrid 2015 in their number 24 issue.

The main informations which include also some known ones below:

- wind tunnel change from 50% Dallara to 60% Williams F1
- new CFD-codes and changed tool chain
- first use of the brandnew full-scale Porsche wind tunnel at Weissach
- improved aero for less pitch sensitivity, more stable aero platform
- monocoque is one single piece for higher stiffness and 2kg less weight
- new batteries by A123 with higher energy density with less cells; 15 % less weight
- reworked engine installation for higher torsional rigidity
- improved bodywork for less weight and less gap width
- new lighter but also much stiffer suspension with changed geometry, FRIC still on board

- slightly increased capacity and a new smaller compressor and turbine with less inertia and changed flow geometry for better response characteristic

- seven speed gearbox with a non-stressed aluminium case, the gearbox is housed in a single piece carbon structure which include the suspension mounts

- the problems with the tyre wear and the mid-corner understeer have been solved

[Spyderman]

Thank you. Very interesting.

[Spyderman]

Also- according to Marc Lieb , the brakes are much improved.

[Articus]

2015 WEC/Le Mans will be titanic if the improvements being quoted by each of these teams is anything to go by.

[Spyderman]

Total mileage for the 919 in 2015 (so far) : 26,635Km
