Well, if there's an extreme emphasis on one criteria, there's a good chance that the end product will look very much the same. I'm sure after Honda entered various cost, packaging, and performance criteria into their models...out will come out the 2nd gen. Prius shape Toyota discovered years ago.

Similar things can be said if F1-racing is the extreme criteria, or hauling stuff pickup truck style, or hauling people minivan style, etc.

It proves what one Automotive Engineering International said, that Toyota is many years ahead of its rivals.

If Honda comes out with a turbodiesel hybrid using their heralded diesel NOx reduction catalyst technology, it will be a cost-independent formidable piece of eco-technology. Even if they come out with a gasoline direct injection - hybrid setup with A/F ratios running ultra-lean in some modes with a recalibrated version of their NOx reduction catalyst, it would be no less formidable and an awesome cost-dependent piece.
 
"Memo to Honda, Toyota called, they want their Prius design back:"

Does anyone know WHY they would want it back?
"P.S. The Prius looks the way is does because Toyota focused their attention on efficiency, aerodynamics and functionality before outright aesthetics. Sexy it might not be, but efficient...........hell ya."

Oh any BTW a fat rear end is the opposite of proper aerodynamics. I'm not saying the prius isn't aero dynamic, but its not because of the gay shap of the body so much.

For the volume best shap is a tear drop, with the fat part facing the wind obviously.

Absolutely not.

The Prius has the most efficient shape for a fuel sipping economy car.

Almost every auto manufacturer or anyone into physics can point that out very readily.

A classical teardrop shape is only efficient for a car like a 911 where overall speed is the objective.

With a slower car the focus shifts to reducing drag and turbulence as much as possible in lieu of things like downforce or cooling.

There have been many studies into this; for a car the size of a Civic which is to be used to carry four people and still meet crash standards and customer expectations it will end up looking like a Prius.

The most ideal body shape would actually be more like the Honda Insight....

Google the Ford Probe series of concepts for more info. Some of them resemble the Insight and Prius.

Beau, unless you "really" know what your talking about, you shouldn't try to prove or disprove facts. I'm sure Toyota did their homework when it came to designing the aerodymanmics of this car. And fyi, a tear drop shape is good in some circumstances, but not all.

Wait I'm confused.

A Teardrop is only most efficent when overal speed is involved?
Can you tell me how an aerodynamic shape that is best at high speeds is not effective at low speeds?

If the shape is efficent for HIGH speeds, it is also for low speeds.
The reason why the Prius could have a good DRAG coefficent, doesn't mean that its overal body shape is MORE efficent than a teardrop. it just means that, openings fender gaps/overhangs undercarriage are more focused on.
As those in aggrogate are very important to aerodynamics.

Additionally I said the teardrop shape is most efficent for the volume, clearly we cannot design a useable car as a teardrop shape due to the proportions we use space, it would contort and skew the shape into something less effective.

And the honda insight has a teardrop shape... If you hadn't noticed.

It tapers off at the tail.
I'm not sure why there was such an agressive denial of the truth I typed, and it actually didn't go against much of what you all said. Its just that the Prius would be more aerodynamic if it were shaped differently, however, the useable volume would drop most likley and cost and ugliness would increase.
