Your know, it is easy to identify when someone has been doing their job way too long and their ideas become myopic. There are just so many problems with the arguments presented that it is hard to know where to start. The example of the steam engine and the rebound effect.... what the heck was the option.... stay with old inefficient technologies so that we don't have industrial progress? What is the parallel the author is proposing? We keep combustion engines inefficient so that we don't increase the amount we drive?

The whole notion that we can't engineer better cars without compromising safety is crazy. My wife drives a diesel BMW SUV that averages in the mid to high 20s for mpg... and still does 0-60 in six seconds. It also happens to weigh 2 tons. To get that same performance in a gas engine you drop into the mid teens for MPG. I recently talked to a coworker who is driving a diesel Passatt to work - and is getting mid to upper 40s for his commute. Another drives a new ford Fusion hybrid.... mid 50 mpg as we'll. This is not eco-ness gone amuck.

To those of you who believe the EPA and all of its regulations are for the "good" of the people why don't you look into all they are really doing?
They are testing and continue to test what they are calling carsinagens and deadly pathogens on people. Inspite of court rulings to stop.
They are lying about all their junk science and using it to increase regulations.
Look into what they have actually been doing with your tax dollars.

Why would any smart person get into one of these little "cars" and expect they can zig in and out of traffic without getting themselves killed?
They do not consider that large cars, SUVs and semitractor trailers can not see them. If you are driving one of these you are taking a big risk with your life everytime you get in your gocart!
Don't be self righteous about them either, the semis are paying for the lion share of your roads!

There is always a PRICE....
Example...One Asian vehicle manufacturer has recently eliminated the spare tire to save weight thus get better mileage. You now get "run flat" tires on some models; these tires allow aprox 50 miles of use when flat and then must be replaced at a cost of close to $500.00 EACH!

Example...Several Asian vehicle manufacturers REQUIRE high dollar motor oils such as 5w40 or 0w20, these oils double the cost of an oil change and do help attain a MARGINAL increase in mileage; however the savings DO NOT pay for the added cost of the oil.

Example...One American manufacturer produces a vehicle that has a plastic underliner to provide better air flow thus better mileage...but when its damaged it DIMINISHES fuel mileage.

They have become Desperate and your safety is in FACT in question

I drove a Buick Le Sabre it got 28 mpg I buy Kia Spectra 5 it gets any where between 25mpg to 32mpg not ever consistent. So I figure I probably average 28mpg and give up a lot of room and the Buick is a heavy car. I don't see how we can't get better gas mileage in our big vehicles. Shoot we can even try putting little wind vanes all over our cars to generate electricity to power our cars at high speed. What ever happened to Brown gas? We have the technology why not use it? I really don't think we want to or those with all the money want us to think there is no way it will happen. Secret combinations I tell you, secret combinations the down fall of our Society as we know it.


How interesting, now I've been in two nearly fatal car crashes in LA in my Toyota Prius. In both cases, I did not cause the accident and was hit by much larger, bigger, less fuel efficient SUVs. In both cases, my car saved my life. The whole front end was smashed in each collision and in the second accident, the heavier, less fuel efficient older model (read 1980s) SUV not only was totaled as well, it rolled and the driver was injured. Me? Well, I barely felt the impact and my airbags didn't even have to deploy. My car is fuel efficient, safe, elegant and fits the bill to bring us into the energy efficient future. Why are so many DN subscribers backwards politically, religiously, socially and apparently know nothing about science or what's going on in the lives of their neighbors. Maybe a Smart Car is not the icon of safety in a crash with a large SUV, but the majority of these fuel efficient cars are, just look at their crash ratings. I think that might be too hard though if all you can see is how much you hate liberals and Obama.

We should go back to horse and buggy. A horse doesn't require all those pesky hydrocarbons.

For all those of you who are opposed to the new CAFE standards, hope you like the Utah air! Breathe in deeply! That's the smell of all those SUVs getting 12 mpg.

this car looks like it's already been in a head on accident!!

What the problem is we have a writer that has quoted a bunch of Lawyers that "know" something about cars. I believe the EPA's date is way too far off. There is absolutely no reason we can't meet the goal in 5 years. Cars won't have to be made of Carbon Fiber or other exotic materials and the vehicles will still meet the current safety standards and we can still have 8-12 passenger vehicles.

First step is to use diesel engines (these engines are already in production for Europe) As an example the Porsche Cayenne with a diesel engine will get 33 mpg might not seem like much but this car weights over 6500 lbs (as much as a full size 3/4 truck)

Second step is to make the cars lighter - solution aluminium (side affect - AL can safely absorb more energy than steel, hence a safer car)

Third step is to decrease drag ie rolling resistance and aero.

Sure there are other things that can be done, but these can be done in 5yrs or less.

What we don't need is a bunch of naysayers, misleading the public. We have the best Engineers the Planet has ever seen!

These "laws" about gas mileage remind me of Camelot, where it was decreed that it only snowed at night time, and the sun shone everyday. Good luck in enforcing legislation that goes against the laws of nature...or nature's God.

In 1977, engineers at Shell wrote an interesting book titled 'Fuel Economy of the Gasoline Engine', published by John Wiley & Sons, New York. Most interesting of all is the information on page 221, stating that they had succeeded in achieving a fuel economy of 377 mpg in 1973, using a 1959 Opel.

Perhaps it is time to revisit this lost knowledge.

I'm sure that if we did, it would be possible to incorporate it into a car that is fairly resilient in the event of an accident.
