- got banned too
watch at about 35 seconds and you can see the car suck down onto the tyres - wonderful

Was this the inspiration for the LeMans Delta Wing?

I think a vintage John Deere row crop tractor might have been--just need to paint it green.

Kustom Dymaxion?
If you like the Dymaxion you should love the Stout Scarab. It was almost as weird as the Buckymobile but far more practical and roadworthy.
Stout was also the same general sort of visionary slash crackpot as Fuller, if not quite as well known. Stout was the designer of the Ford Trimotor aircraft.
Be sure to look at the vintage film footage of the Scarab on the road.

Here is one car where I can honestly say I don't get it. What was the point or the purpose are lost on me, truly. The creator (named Davis if I recall) built several of these things, all on the same non-premise. The design is sort of like an airplane with the nose wheel thing going on at the front and the body is built rather like a light aircraft fuselage, but why these should be desirable features on an automobile beats me. All I can say is WTF.

I was talking about the Fascination, obviously.
In the case of the Deltawing, I totally get how Bowlby seized upon the possibilities in CG and aero that make the car viable. I find that aspect rather clever, actually. What I don't get is what the car is supposed to accomplish from there. In the Fascination there is nothing to get, really, in that there is nothing viable about it. Whatever appeal the designer saw in it was unfounded.

To me, they are both equally pointless and flawed concepts. In both cases, the perpetrators have seized on some idea and then take it to an absurd length.
A rectangular, four-wheeled configuration is in no way the pinnacle of racecar design. It's only what we're used to.

There is a huge difference between the two. The Deltawing is based on the idea that a vehicle with asymetric weight distribution and aero CP need not have front and rear tracks of equal width. If you can identify the idea upon which the Fascination is based, please tell me. Near as I can tell the latter car is a sort of whimsy.

So which museum are they putting the Deltawing into?
Did the Deltawing kick your dog or something?

It's a bit like when you see a distant shot of a fighter banking, and you're not sure if it's coming or going.
This reminds me of an old Irish joke about semen and urine

I too am working on a vehicle with a more extreme CoG position than the Deltawing, it's much further down the road and here's a prototype.

Seriously, there is no future for this aberration, unless someone wants to fund a series for daft-looking unstable cars. The Deltawing has no competitors to play with and meets no existing, or indeed no likely future set of regulations. It won't be back at Le Mans as it has had its 15 minutes of fame there and the ACO will give garage 56 to some other new concept . So a museum is the only place for it to go now.
Unless someone knows better?

Next year's garage 56 car is the hydrogen fuelled GreenGT H2. It's like an overweight open wheeler. Currently over 1200kg though they are aiming for under 1000kg. According to Eurosport commentators, shielding required for the tanks pushes the weight up.

That may all be true but it doesn't make the car any less novel or interesting, which is more than you can say for a good part of the field at LeMans.

I wonder about the costs of the concept. In the dollars-to-laptime ratio, whether there are advantages over the traditional LMP2 route. Although in any rules package the money comes in maximising the dimensions. I mean look at how much people manage to spend on NASCAR.

Well, watching it wobble around Arnage corner where every other (conventional) car looked far, far more capable. And then a little sideswipe threw it right off the track into the wall. The clever, revolutionary, world-changing concept simply didn't work. That's the source, chummy, the evidence of our own eyes - or at least for those not blinded by some sort of bizarre denial of the truth....source, o enlightened one?

Looked wobbly? Seriously? You don't have any data to present on cornering speeds or lap times and you dismiss it on your meaningless subjective evaluation watching video? Seemed to me to be objectively working exceptionally well for a new concept in its developmental infancy running against equally ridiculous conventional racing cars with a 100 year or so developmental head start.

Seemed to me to be objectively working exceptionally well for a new concept in its developmental infancy running against equally ridiculous conventional racing cars with a 100 year or so developmental head start.
But the question is where does this thing go now? I can't see how any series is going to rewrite their rules to accommodate a one-off car. If it has to compete on equal terms with real cars, it will be blown away.

Seriously...
I'm fairly ambivalent to the Deltawing, but to be fair to it. it did competitive lap times. I just have a sneaking suspicion that you could get pretty close to what it achieved with a "conventional" wheel configuration. Unlimited aero rules and torque vectoring would certainly help a conventional car.
But your criticism is so ridiculously dogmatic that it's got my back up :-)
The accident in the Porsche Curves is a normal type of situation at Le Mans. Look at the Davidson (Pug) Magnussen (Vette) crash so it can happen just as easily for a "conventional car"
Speaking to some people in the pitlane the front tyre was incredibly conservative due to it's size, which means the package is by no means optimised, which goes to desmo's point.

The reasons for this are as follows
1)traditional open wheeler racing is getting less popular over time. One reason might well be that the cars all look the same, or in the case of current F1, look stupid. Therefore changing the appearance drastically might attract fresh eyes. I doubt it will, personally, but they may have evidence to support this.
2)Flips due to interlocking wheels are bad news. Getting rid of the front axle reduces the chances substantially, or completely.
3)Almost any racing series has arbitrary rules, so complaining that a spec series is inefficient or whatever is illogical. You could easily design a car quite cheaply that would destroy current F1 qualifying times on any track, if the only limitation was say maxima for fuel composition and flow rate and vehicle length width and height. Fan car.
4)It's a fresh technical challenge
5)It was designed by some people who have their heads screwed on, have spent far more time thinking about it than I have, and have put their money/time on the line.
6) Ortiz claims the aero is less sensitive to disruption and so passing should be easier

Petrol head figures aside, how much longer did the DW go during the race? Much longer stints due to less fuel and tyre consumption?
Fuel stints were 11 laps because they also ran half the tank size of a comparable LMP2 car (40 liters). As for tires, no data from the race, but as far as I'm aware they ran the whole of Test Day and all of Wednesday on the same set of tires.

It seems like in just about every country the domestic tin top series is more popular than their open wheelers. V8s vs anything else in Australia, NASCAR v Indycar, DTM/BTCC vs F3, etc. Italy is the exception, but they only care about Ferrari. And in Italy and Spain you could say motorcycle racing is bigger than everything bar Ferrari, but it's a close run thing.

How much did Ben Bowlby make out of the deal?
For someone who needs a high profile to continue in the sport I have to take my hat off to the man for the concept. It is on par with the Tyrrell 034 and will live for ever. Well done that man.

Probably targeted at maximum efficiency, minimum drag and weight for cutting down on pit stops...less weight on fuel..four cylinder turbo top speed dependent on low drag...apparently it has next to no steering feel from what i'm reading on racecar engineering's article on it, volume 22 number 6. read it tonight.Well I'll try again. What was the mission of the vehicle as designed?

It was designed to stir the pot, and it achieved the goal 110%. It was built within the rules, wildly different from anything else, and it didn't fall flat on it's face, that's a job well done. All racing priorizes rules over 'technology', the idea of trying something vastly different is exactly the kind of spirit the technical proponents should applaud the most.

WHat rules were those? Wasn't it originally designed as a possible new spec car for Indy racing, and therefore effectively wrote its own rules?It was built within the rules

Yes I missed the mark first time round where they were not quite going for all out lap time but instead 24 hours through being nearly twice more efficient than the other LMP1 cars but interestingly gamble a lot on depending too much on the rear axle where it needed a far better surface to actually perform that Le Mans would not be able to offer in some of its corners. Also lack of under tray surface also meant they would not be able to get any where near LMP1 ground force, a critical ingredient for Porsche Curve. Have not finished yet too mcuh distractions at the moment.Poweresteer- So now you've read the article, what was the mission of the vehicle as designed? How does that change your assessment? Big clue, you missed the important stuff completely first time round.

How about a diamond shape race car, just think of the aerodynamic advantages!
Of alll the festering nonsense, diamond wheelplan is one of the worst. And yes it has been proposed, designed, built and publicicsed.
French car, 1930s, sorry I haven't got a linky.
