Do take into consideration that these prototypes frequently travel above 200 mph. At such speeds EVERYTHING is amplified. I know at a stand still my mid-size SUV can handle heavy cross winds. At 65 mph on the highway in the same wind, things can get hairy in regards to staying between the roadway lines.

Everything is amplified, including downforce values. If LMP1 cars produce similar/more load than an F1 car, I doubt it would be blown over by wind!

WolfsburgRS · 2 Dec 2010, 22:05 (Ref:2798841)

I could easily see a strong gust making the difference between control and out of control if conditions were right. I'm not sure what the aerodynamic interaction is between the shark fin and the rear wing, but I'd imagine it's considerable... Just the right (or rather, wrong) combination of speed, direction, mechanical grip and add in an unanticipated gust of wind and it could be bad.

That said as Lola T70 mentioned, you would think this problem would show up on F1 cars if it was a problem.

Agree, this is complete nonsense.

I wasn't saying it would be blown over, just adding that from my (very limited aerodynamics) perspective that with a cross wind of sorts, whether or not this is what caused any crashes, could aid in the loss of control in one of these machines, could it not? Sorry if my thoughts are totally off base.

TF110 · 4 Dec 2010, 11:30 (Ref:2799465)

Does your car get blown over on it's side in cross winds? How about SUV's or big 18 wheel trucks? Unless you have hurricane force winds, I don't see anything happening to these cars with the 'fin'.

I don't think anyone seriously thinks the car physically tipped over on its side. More like forcing the car offline or to become light causing an accident.

But the people in the know seem to think its not possible. I doubt we will ever find out from Peugeot.

Tom908V12 · 12 Dec 2010, 13:18 (Ref:2803265)

Now that we know that the Audi R18 will have a TDI V6 engine, do you think Peugeot will opt for a HDI V6 too, or do they stick to V8(or even something else)...what about the latest rumours

Latest is still V8, but someone mentioned to me yesterday they had specifically heard 3.5 liter turbo diesel V6.

Victor_RO · 12 Dec 2010, 13:35 (Ref:2803273)

Any particular reason why they wouldn't build an engine to the maximum capacity allowed by the rules? Packaging? Some kind of dynamics-related reason?

Dani Filth · 12 Dec 2010, 13:35 (Ref:2803274)

would it be any gain in not actually going to max 3.7 for diesel .. difference restrictor for 3.5 ?

Thanks for this info MM

Tim the Grey · 15 Dec 2010, 10:49 (Ref:2804667)

Mayhap the R18 V6 prompted that rumour? Seeing as MM has commented on the 90X being a V8 since. Assuming sources are accurate, of course.

I am surprised the 90X may well have a shorter wheelbase than the R18, as visually, it looks longer. Perhaps I need to see my optician!

gustavobamba · 16 Dec 2010, 12:12 (Ref:2805105)

Where and When did Peugeot will present the 90X???

Anybody knows????

Tim the Grey · 16 Dec 2010, 16:29 (Ref:2805194)

At Monza, on track, running.
They had a limited Press Release when the 'spy shots' were published.
This would be, oh, a month back, now?

Like Audi did, officially, not tests. I don't think that car is the final version!!!!!!

I heard something about a mid-January official presentation. The 908 was officially unveiled to the press in '07 in early January (Jan 4th I think).

hello, you think that the car tested in monza is the final version?

Probably not... after all, we only saw the final version of the 908 in 2010.

Tim the Grey · 17 Dec 2010, 11:45 (Ref:2805540)

There were a LOT of new parts on that shortened 908 if it was just a mule...
Just read this thread!

HA. They've probably seen the Audi and gone 'Oh.. shot, we have a wee bit more work to do here'.

Plex · 29 Dec 2010, 13:24 (Ref:2809189)

Whats the lastest if any with the 90x?

That's depends..
What's the latest you heard?

Tim the Grey · 30 Dec 2010, 18:12 (Ref:2809471)

It has a roof, 4 wheels, and a Lion Rampant badge. Any other bets are risky!
