very.. very.. very interesting article..

http://www.popularmechanics.com/cars...=1457_31437471

i'm curious if the benefits would always be there or if the narrow front has to be past a certain size to be effective

hmmm

That's incredible.

Really interesting story. Very curious what kind of sports cars will spawn from this concept.

dem00n · 11-22-2013, 02:16 PM

That's interesting.

As cool as a penis shaped sport car will be for the rainbow crowd (Aaaa!) i don't think we would see anything like this be accepted as a standard for generations to come.

It would have to be really good, like topping everything else in class good and be able to hold it for a while.

Edit: I was just thinking, how would something like this would take to frontal crashing in the real world? Wouldn't by chance the driver be more in danger with a car like this?

probably better than a square brick everyone else drives

my thoughts is that a triangular (not necessarily penis shaped) frame would have a higher chance at deflecting away from whatever you're gonna hit at a right angle

that's how tank armour works....

my question would be how tight the front end would have to be for this to be a benefit, or would any shrinking of the front track would start to yield a handling benefit..

like, what if we put on +55, 16X6 wheels on the front with 205 rubber and much higher offest tires on the rears?

no axle at the front could mean custom control, shorter control arms and cut camber plates for greater effect

Ummmm... I don't know what I'm talking about here but (I think) the the whole narrow front/wide rear concept is tied in with the weight distribution. The concept works on the Atom (massive rear bias) and works on the Deltapenis for the same reason.

yeah, probably little to replicate in an FRS or similar

but somehting like a RR Porsche or Elise... :o

I'm in a facebook group with a lot of motorsport industry guys (past and present, heavy on LMP cars) and it's amazing how many of them hate the Delta car. As far as I can tell there is no real specific reason. Many of them hate KERS for that matter and most "new" things.

I'm pretty excited about all of it. That's a great article!

Or a dune buggy chassis with the engine behind/on top of the rear wheels.

The article made it quite clear that weight distribution is a HUGE factor in making this work. The car sticks in corners because all the weight is over the massive rear tires. The front end just points it in a different direction. I imagine it would take an impressive wing over the front end to generate enough downforce to keep it safe at speed.

This thing also needs very sophisticated electronic traction/stability control, AFAIK. Probably why the traditional guys don't like it. It's naturally unstable and not 'honest'.

But that makes me think about fighter jets, and when fly-by-wire allowed designers to create ridiculous manoeuvrability that they previously couldn't.

Too bad it's so ugly.

I realise the video doesn't reveal all but it is explained that the set up is quite stable due to the design. I think the differing roll stiffness forward/aft vs roll due to the rear anti geo is very trick. 10.20 in the vid
