Driver changing might be eliminated when pitstops will become much longer this year... with the (imho stupid) two mechanics / one wheel gun rule (instead of two wheel guns and four men). ALMS did not adapt this rule change.
I wouldn't exactly call the Audi a brick. I'm sure a lot of engineering goes into making sure the front of the car pushes air up and over the open cockpit.
Closed cockpit cars are not that much more aero-efficient. Closed cockpit cars also are harder to get down to minimum weight ('they weigh more' is not technically accurate, as they can weigh less, though this is harder to do), their centre of gravity is higher up (as they have more material up higher for the roof) and they have a much larger frontal area which can actually result in increased drag.
Aerodynamics are a lot more complicated than you might think. It's not as simple as smooth lines = less drag.
While I'm not involved in the Audi development, nor a real authority on the matter, I'd say a much smarter thing to do would be to push the air to the sides of the cockpit and not over it, per say.
[EDIT] Oh yes, thanks for the pics/links Deggis. I don't know how you find this stuff!
well i see a slight resemblance to the typical audi styling, especially the R8, quite like it, doesn't look like the typical openwheeler with fender design
LeMans is sort of an 'invite-only' race. Maybe they were not invited, or maybe they wanted to run the car in race conditions before spending the large amounts of money necessary to run LeMans?
[EDIT] Mulsanne's Corner has a look at the large R15 photo, and Mike has dissected it further. Seems the R15 has a quasi-front wing in place of/integrated with a splitter?
I know this wasn't the point of your post but I have to correct... you know the invitation only happens if team is 1st or 2nd (all classes) at Le Mans or ALMS/ALMS/FIA GT championships and 1st at Petit Le Mans? Or then the team applies for entry and hopes for best. But its not every year new manufacturer wants to join in, so getting the entry accepted is probably smallest of the obstacles for Acura.
Probably did not apply last year. Only the official invitations have been published, full entry list will be published later this month.
By the way:
The selections are sometimes little bit introverted, I guess that's why that "Etc."
That "maximum of two cars" is stupid, only causes pointless naming schemes, like Peugeot last year: 2x "Team Peugeot Total", 1x "Peugeot Sport Total". Aston Martin probably going to do something similar.
Yep, they did. I recall reading something about it after the lists had been posted in which the team manager (or some high up anyways) said they were surprised that they were not accepted for the event that year. I was pretty disappointed, too, since they had that awesome new car last year and I wanted to see some footage of it run.
.. Maybe I should try to find some pics of it. Maybe some high res racing shots are available now.
ACO decided to cut 40 cm from the rear wing (2 m --> 1,6 m). It's going to slow down the cars maybe about 2 secs. Stupid move, not only because of aesthetics but the change is going to hurt a lot of the small private teams. ALMS decided LMP2 teams can use 2008 spec wings but with +25 kg.
thats a nice line up there, im suprised that a team will be using the R10s, but i suppose that they will still be competeative with the rest of the field
