Cd and blunt front ends

The "optimum" nose has the lowest stagnation point - ie. less of the total flow will go under the car vs. above/around it.

The nosepiece extension on my car is shaped like the -14% curve. It was done to lower the stagnation point at the front of my car and to blend the shape of the nose in with the curve of the false windshield I was working with at the time. A fringe benefit of the reshaped nose has been the absence of smashed bugs on the nose of the car, the stock flat bumper used to collect a bunch during the summer months. A second fringe benefit is the "deer scoop".

Car ownership goes far beyond function and utility, it makes some kind of statement.

If you recall, back in the '90s cars were getting more rounded and sleek. Some of the lowest Cds to come out of Detroit were born in that era. What happened? Car buyers complained that the cars all looked alike, and worse, that they were too plain and feminine. So, out came the boxy shapes and bulging wheel wells. Car design has to satisfy many masters, which means that every design that hits the street is a compromise.

In 60 days,the United States may have a woman vice president in the White House.That's never happened before.If Madison Ave. is very effective,it will happen.Women,while similar to men are physically different.Some American men think those physical differences are ugly.--------------- As you have mentioned,many Americans would think the "boxfish" ugly.However,in 60 days,if Madison Ave. wanted American car buyers to buy low aerodynamic drag cars,they could do it,regardless of what the cars look like.Very few people new anything about the Republican VP candidate a few days ago,now she's a household word.Same could be for cars.That's all that stands in the way of 100-mpg cars in 36-months.That's all,but it's quite a lot.

A very interesting analysis. But someone is paying to have Sarah Palin become a household word and make her attractive to the voting public. Who will pay to make the Boxfish desirable? Car companies pay Madison Avenue to make the cars they already make or will make desirable, they're not motivated to spend money to make people adopt a new way of evaluating automobiles. Two years ago, it was all about power. Now, it's all about fuel efficiency. Yet it's the same vehicles being advertised.

That's because the vehicles for sale TODAY were planned 2 years ago. Come 2011 I expect the available inventory to reflect what we are experiencing today. Not many industries can change product focus overnight. So, you sell what you've got or you close up shop.

The Aztec and box fish are style challenged
but there are better examples nice aerodynamic shapes
here is one of my favorites

and may Detroit never go back to this style-less aero brick

that is a blunt end I can do with out seeing again

Hello,

A shape that seats four and has a Cd of 0.19 is hard to argue with. Form follows function. Some more pictures:


Notice the screen in the upper left:

We all realize it's cheating, but concept cars never have wipers and very seldom have mirrors.

Hi,

They put cameras and screens instead of mirrors. I can't speak to the wipers on the Bionic "Boxfish", though.

That is not an entirely un-biased opinion about Sarah Palin, so I have a rebuttal. This is NOT going to be the most popular view on this website because, quite frankly, most of us here are not Republican, as I am.

Who are the people that are paying for her name to become a household word and make her more attractive to the voting public? The Republicans? The Democrats? The Media? Surely you must be mistaken in thinking that someone is putting their hard earned money on this VP candidate to support her? She is by-in-large more experienced than Obama in all matters of governing and leadership because she has held offices and positions that he has not. He has not held any positions of power besides Senator (a job in which he has not performed a single act in the past two years due to campaigning for position of President.) She does not need assistance in making herself well known, her character and values speak for her.

In short the Republican Vice Presidential candidate has more experience and is more prepared to lead this country than the Democratic Presidential candidate.
