That looks to me like it has 4 wheels in total....

I thought it always has had 4 wheels - never 3.

Me too ...   Never read anything about only 3 wheels (otherwise Morgan might have a go at LM with their 3-wheeler )

You thought right...

Every time I see it, it brings to mind Evel Knievel's Sky cycle.
Well there's some hope, that didn't fly.

Those look like VERY narrow tyres..

High speed front puncture or blowout, and I would not like to be driving.

If it does run at Sebring could someone look to see if the front tyres are still fixed with 3 studs, seems odd, rear tyres are fitted with one standard nut.
Technical reason?

Cutting edge of technology... with a pair of Citroen 2CV 3-stud wheels on the front.

I think they've gone for 3 nuts for lightness - no need for a big stub axle/hub assembly. There's no (visible) suspension. Only 25% of the weight is at the front, and thats about 120kg, or 19 stone.  And it all has to fit under the bodywork

The trouble is weight transfer.  When you put the brakes on, Newton's laws put a lot more weight on the front and those skinny little Michelins will complain.  Likewise, drop the clutch and it might wheeley.  And approaching these extremes will be lethal

I always thought the key to a good set up was balance cross the axis's and the load transfer when going around corners (Hence off-set Indy cars). if this works it will throw out all common thought and wisdom on race car set up. It must have a pretty trick diff to help pull the front around. If thats the case,hope it doesnt fail.

It's running at Sebring Thursday...http://campaign.r20.constantcontact.com/render?llr=74u6ohdab&v=001QkDMjGI5V9ZVrWdmD1o3dCH1EaGSCr6eFCncQBsWSqiYZdfp1YBZqai4uUC-GtVnVbZm23ccjIj74tFaIXZiMa9CJZsuhnrzHRXNGJ5BMoL5d9H-0o6VoVoaI50UR2-H

Jesus H Christ, seriously...
Looks cool is a long way from being a real racing car.

I'm sure it will be fast down the Mulsanne, no rear wing to hold it back.

Just hope whoever is driving it can hang onto it over the bumps and ruts. With almost no visible front suspension and therefore little damping at the first sign of a bump the whole think will just launch and steering control will go.

The crumple zone must also be compromised by having those wheels so close to together, head on wont they be pushed back into the drivers feet?

I am sure there are some very clever people involved who must have done the sums so are confident it wont be the death trap it looks like.
