Shock horror, potentially built around an Aston Martin AMR-One tub!

Well I hope the only reason for that is driver safety otherwise they have just blown their "cheap" concept out of the water.

I guess that's probably why, with a tub that has already passed the FIA's crash tests that's one worry less.

Le Mans has always been about cars that have some (admittedly sometimes rather limited) sort of connection to road cars. The Deltawing has none - unless you count the Reliant Robin. It has no place in sports car racing.

Like the 917, MS670, 956, 962, R8, R10??

Quite. I'd prefer someone to have a go with an Ariel Atom.

Until enough people realise they've been fleeced I suppose. It could drag on for another year yet.

Exactly. You do know that you there are/were road registered Porsche 917s, 965s and 962s? In fact, if you bought a 956, it came with a set of keys for doors and ignition. As for other sports prototypes, as I said, they have some (admittedly sometimes rather limited) sort of connection to road cars. You know, four wheels covered by bodywork, two seats, lights and so on.

Interesting that the Deltawing has gained the 56th spot for the 2011 Le Mans race (according to Autosport) so presumably it can time travel in addition to all its other supposed virtues!

I only ever heard it was slated for 2012 Lemans.

This is worth the watch although Miller does well at contridicting himself...

Safe to say it's this he was talking about. Marino was at AAR a few days ago, I suspect getting ready to do a shakedown run with the car.

EDIT: And proof.

Ohh year.. And considering that it negotiated the bend with a violent 20mph, it hardly displayed any bodyroll at all (OK, so it rolled quite a bit, but at least the inside rear wheel stayed on the ground)

Nice to see it actually exists in the flesh, can't wait to see how it goes when they really give it the beans.

It's pretty cool to have the balls to build this, and go against the norm, but I'm still a huge skeptic.. still looks wrong to me, and slow.

Also, must be kinda hard figuring out where this thing ends from the driver's seat.. not easy being in a close battle while having to use a sextant.

Beats some people's predictions of the thing rolling over when trying to tackle a corner at 5mph though. :lol:

I was delighted that a WSC (which was supposed to be the fastest class) couldn't win in 1994 and was really showed up in 1995 when they were all beaten by an actual GT1 car.

They followed the rules, they got cars complied and legally registered for legal road use, more legal than the Monaro's at Bathurst 24 hour and I seem to remember BMW dicking everybody with an M3 recently as well.

I wonder if that can only fit within the parameters of having 4 wheels - themselves being within reasonable parameters ie; basic rectangular footprint?

The Delta Wing has 4 wheels. Yes the track is different front vs rear, but some single seaters have that. The Delta Wing just takes it to extremes.

You see so many unimaginative criticisms that you end up speed reading them.

I understand that people don't like the way it looks, there's no denying it looks weird and not like a 'real' racing car. But then everyone complains that there's nothing new in racing, the rules are too restrictive, etc etc.

But then again, under the original concept rules were to force this configuration for Indy, and I can't see the bright side on that happening.

Nice, they will get a shot at Le Mans. Good for them. But I still believe it wont work that great.

Not sure what a "real racing car" should look like anymore, recent F1's are certainly just as confusing.

I'm against the width of the rear, I can see it tangling with other race cars such as late braking dives.

I think the rear 'tailfin' is just silly, not sure what purpose it serves either and looks better without it ..

No, trikes are easy to model, even in a basic package like LapSim, just set the roll stiffness of the single wheel axle to zero, etc . In ADAMS or equivalent an experienced motorsports analyst could get you laptimes with a meaningful correlation to real world, given adequate track profile and tire data and aero.

This question came to Bowlby when the thing was new. He said that the disparity between front and rear track were basically unavoidable parts of the design. However, if it were a serious problem you could always attach some carbon fibre appendages to "fill out" the front to the width of the rear track. But personally I'd love to see how drivers adapt their cornering technique with such an unusual front-end.

In 1923 one came 5th behind three Sunbeams and a Bugatti, 5 finished.
It was 20 minutes behind the winning Sunbeam.

They will adapt their technique by bringing it back to the pits and saying "Whose bloody stupid idea was this..."

Steers well and was hauling ass. Bit twitchy but likely bump induced with early days for shocks and springs.

Just thinking that the front tyres are going to be often on a dirty line between the normal vehicle's track tyre lines, may not be good.

Here's some comparisons ..

0. Deltawing 52 seconds

1. Chevrolet Corvette C6 66.32
2. Dodge Viper SRT-10 66.60
3. Porsche 911 Carrera S 66.71

= less 22% aprox



Road Atlanta
LMP2 time = 73 seconds (qualifying).

Corvette C6 = 95 seconds

= less 23% aprox

Different tracks have different needs that might suit one and not the other but not bad for an out of the box radical concept to appear to be near the mark immediately.
