I know i'm beatin' a dead horse here but...

It's well known that only a fraction of he potential energy in gasoline is utilized in internal combustion engines. And no matter how much car makers hype their technological advances in engine design, we are still essentially burning gasoline the same way we did 100+ years ago... by dumping liguid into a cylinder and lighting it up.

Anyway, gasoline (or other crude oil based products) isn't the future (or should't be) so my point is irrelevant in the grand sceme.

Fuel efficiency isn't hard to achieve. The stripped down version of the Geo Metro boasted over 50 mpg. They did it with a tiny 3 cylinder engine and it had nothing in it.

And that is the rub. We need our air conditioning, power windows, heated leather seats, navigation systems, power everything. The plush stuff comes with a weight penalty. You can only get so much power and efficiency out of an air/fuel mixture so in order to get higher efficiency you have to push less weight around.

60 mpg carburetor. Of course it could happen. In a small, lightweight no frills car. I think 52 mpg was the highest possible in the aforementioned Geo Metro. Not too far off the mark, but you were in a tiny car that had seats and not much more.

I seem to remember some rumor of an 80 mpg all ceramic engine created by Volvo and snuffed out by the evils of Big Oil. Pretty sure that one was crap too.

It always tickles me watching some dufus in his rattly vw tdi golf, or any of these noisy rattley mercs struggling up the street. Loud and slow pos`s

Ya spending 80/100k on a car, WTF do you care about mileage. Seriously, some of this and last years deisels are louder and rougher than i could personally handle. And deisel over here is nearly 2 bux a liter.

Did someone same Image ? lol

I got a motorbike that gets over 100mpg. This week for work I racked up 800 miles and spent under $30 for gas. compared to the over $140 it would cost to drive that mileage on my car. End of year, I save over $1300 in gas and tires/maintenance ect adds to the savings as well. OH and my insurance is 25% of the cost of the car.

I agree, cars should be getting much better gas mileage and I believe that my motorbike could probably be getting 300mpg with current technology infused into the engine.

I'm not complaining at 32mpg but I guess it can always get better.

With prices here in Orlando now at 3.85 my guess is that 4.00 mark is right around the corner and just in time for summer.

What a load of rubbish.
Clearly you have not driven these vehicles, at least not for any period of time.
I drove a VW TDI All Wheel Drive van for 5 years at work. On sealed roads and up and down mountains on rough to very rough forest roads as part of my job.
The vehicle was loaded very close to maximum weight and the aircon was "never" turned off.
With it's normal range tank, I used to get between 750km~870km range per tank and that it always without pushing it to the edge.

Tested a Mercedes Diesel "used" vehicle on a test drive, it had more then enough power to any other passenger vehicle that is seen as a family car over here.
No rattling, great torque, range over 800km per tank and fitted out with all the extras you could think of that you could get for this particular model. In other words no stripped down light weight version.
Unfortunate they didn't come to the party in regards to trade in/change over cost...otherwise I would have purchased it instantly.
A well designed and quality Diesel is more then competitive, despite of the idiotic higher fuel cost of Diesel, compared to normal Petrol over here.
Compare that to my replacement vehicle which is a Isuzu D-Max (the Holden Colorado is just a re-batched version of it) and this 4 cylinder Diesel is just rubbish.
Low power, little torque and bloody fuel hungry.
This just proves that they can still build crap engines even today, if they put their mind to it.

+1 that.

The newer TDI's are pretty awesome. They have a few racing in proto class American LeMans. Smooth and quiet, and faster than anything else in the circuit. Suprizingly good stuff.

...but they could go 1000 MPG if Big Oil/Methodists hadn't bribed the engineers to not use crazy uncle Fred's Blamo-framulation Magnetophasedingle Expander Valve.

+1 these are the cars that developed the new TDI stuff we can buy now. Power and torque. All friends of mine.

Audi tested three protoypes for 12 hours at Sebring for three days in a row with out any big problems in January this year. I know i was there. The best part you do not need hearing protection when the car goes by over 200+ mph! Oh and they can spin the rear wheels at the fast part of the track at Le Mams, now that is power. also they get better mileage than the gas protoypes.

I drove a TDI VW bug once. It got awesome mileage but it was ABSOLUTELY the most gutless car I've ever been in. The deuce & 1/2 I drove in Iraq had more get up and go!

Stupidity can be cured. Ignorance is for life!

Umm.. so we all have computerized fuel injection with oxigen sensors and the whole nine yards specifically designed to ensure the fuel is completely burned (and all possible energy exctracted) and some carburetor (snicker, snort, bwaaaa haaa! ) designed by a mentally defective 20 year old is gonna save us all?
Not that I believe in the carburator conspiracy but IBM took that stance with Bill Gates and Steve Jobs. Look where IBM is today vs. Microsoft and Apple. It is possible this kid was on to something.

Yes having completed a 4 year apprenticeship and having a certificate of proficiency issued by the State authority that says "Motor Mechanic" on it.
What is hard to comprehend about "Qualified Motor Mechanic"

How much does it weigh.
Is it built like a coke can or a real car.
Around town economy figures.

If people are so worried about fuel economy forget the myths.
Unbolt the car seats bar drivers seat and leave them in the garage at home.
See a gain in fuel economy and improved handling and have a great excuse for people who always ask for a lift somewhere.
(Plenty of room for the RC toys to sit.)
Get all the junk out of your trunk.
Pump up the tyres more then once a year.
New plugs and air filter on schedule.
All that will make a considerable difference to economy with no smoke and mirrors.

It is complete BS
And I read the links

http://fuel-efficient-vehicles.org/...ws/?page_id=785
http://www.byronwine.com/files/Gone...&theFIVS605.pdf

Aside from the fact I want a the last 15 minutes back those pages stole from me.
There is absolutely nothing in any of those pages that provides a single detail about the system aside from some mad drivel about fuel vaporizing and magnets.
Nothing anyone with qualfied understanding of engines could put senses to.
And a of lot of other mad dellusions from the inventors themselves.

There is so much wrong it is hard to know where to start and I dont have a week to sit here and cover it all.

Suffice to say there is nothing to discover other than the old adage
If it sounds to good to be true it most likely isn't true.

I use my Kawasaki Ninja 650r for commuting anytime the weather allows. I average 66mpg. My girlfriend's Ninja 250 gets 68mpg. It helps make up for the 5 1/2 gallons worth of leaded fuel exhaust my airplane puts in the atmosphere each hour I fly. I am closet green and only run my 15mpg pickup when I have to.
