Delta Wing Street Car

Jalopnik: If You Want 70 MPG, Your Next Car May Have To Look Like This



"The DeltaWing idea is based on four ideas: reduced weight, increased powertrain efficiency, decreased energy consumption, and improved aerodynamics. They say the street car will do all of these things, and their current targets are zero to 60 mph in six seconds, a 130 mph top speed, and up to 70 miles per gallon with a small four-cylinder engine with somewhere between 85 and 110 horsepower."

I think it's backwards. Should be reversed for a proper tear drop shape.

Looks an awful lot like the Vigillante of over 20 years ago:



Welcome to VIGILLANTE'S Page 2

Why not ditch the fourth wheel and gain all the benefits of being in the motorcycle category?

I'd think a frontal impact would look much like any rear-engined car. Better not ever ride in a VW, Porsche, or Corvair. Or Ferrari, Lamborghini, etc.

It would depend on the center of gravity. If it is low enough, it should actually be stable, while having the wider end in front is more stable and more aerodynamic.

People always worry about the front!

How would a rear-end collision go with two wheels in front and one in the back?

*chuckle* Add the Tesla Model S (broke-the-rating-scale) to that list.

The handling should be similar to the race car. The cabin is far back from the front wheel, and the mechanicals are packaged around the rear axle, so it should be pretty good. Frontal and offset crash ratings should be good, but I'd worry about the small overlap test, since that might expose some vulnerability in the cabin crash structure by bypassing the front end completely!
