I believe it's possible. We've all head the rumors of the 100mpg car or truck, I'm sure there is some truth to some of those rumors.

376mpg is a stretch.

The Shell Oil 1973 Test Car - 376 miles per Gallon ? I don't see how that can be possible with that set up.

Something like 25% of energy is lost in the cooling system of a internal combustion engine.

I find that very hard to believe.. Think of the change in technology from then to now... If cars built today(hybrids) can get like 50mpg give or take, who was 10 steps ahead of the technology now back then, and was able to beat that by 7 times without using electric, bio-fuel, etcc... i smell Bullchit!

you guys are crazy. gas is at what? 3.20 a gallon now? you don't think that the oil companies don't purchase some technology that drastically increases gas prices so they can stay in business?

we've had technology to greatly stretch a gallon of gas for years. oil companies buy it up and file it away. its a multi-billion dollar business, if we only used a gallon of gas or less per week they'd be out of business and we can't have that.

I smell a conspiracey theory. I believe the oil companies have and do what you say as far as other technologies especially, but to say they would be out of business? No way. There will always be oil consumption especially by the military.
But that car that Iolas is reffering to looks like a backyard eccentrics attempt at something new. My kid could come up with something better.

I have pulled 55 mpg from a 1971 VW Superbeetle, and that was using a few tricks I learned here and there. The trip was from Memphis, TN to Palmer, TX. 11 gallon tank, 8.5 gallons to fill it once I arrived. I was easy on it the whole way, and never went past 65. This is someone without an engineering degree or any major education past high school.
Now add to that an actual engineer and a wild imagination, and it doesn't sound too far fetched. Overall mass and drag are the two worst enemies of fuel economy. Cut down on them (remove excess weight and lower the vehicle to decrease under vehicle turbulence), and the picture gets more clear.

Out of business, no. There will always be some market for oil regardless. But do you think BP, Shell, Sunoco, Exxon...all those would be turning billions? probably 1, maybe 2 of those companies would still be around in some capacity, or maybe a lot more smaller enterprises, who knows. but certainly not in the capacity that they are in now.

Exactly Can

I agree with you and BroncoXLT4X4. What people forget is Austins were nailing down over 50 mpg in 1959 using 1930s technology.

Closer to home and now, Those Pontiac Fireflys of 15 years ago were nailing down closer to 70 mpg..

Heck my Brother's 86' Escort pony, a total stripper, radio delete car could easily achieve over 60 mpg. He still had a carb IIRC as well as only a 4 speed manual, never mind a 5 or 6 speed.

I vividly remember visiting England and Scotland in 83' and being blown away with what they could do with a 2.0 litre car. Heck it would have blown the doors off my buddy's, then new, 83 5.0 litre Mustang, and it still got nearly 40 mpg too !

Using only todays technology they should be able to do a whole lot better with a gallon of gas.

Smokey Yunick's modified Fiero has all but been swept under the rug.

This $h!t's gotta stop ! If it was only benefiting North American oil execs($400,000,000.00 to ONE Exon exec upon retirement), it "might" be okay. Unfortunately countries that hate us and everything Western are getting rich and funding terrorism with the profits.

I remember borrrowing a POS 1989 Pontiac LeMans when I was 16 to drive to Seattle. That car got nearly 45mpg driving to Seattle and back, it was a 4-spd--no OD.

Economy cars today can only muster 35mpg? Something is seriously wrong.

Yeah they're holding out on us, but we as consumers are at fault too. We want bigger compact cars, with more power and room, so they build em' heavier, bigger, safer and faster.

Did you know that a Neon outweighs a 340 Duster :shocked

The "new" (BMW) Mini weighs over twice what the original Mini weighed too.

They lost that go-cart feel as well. We just have to admit that despite millions wanting more fuel efficient vehicles, creature comforts win out each and every time, with performance hanging high up there with them. We know that, and so do those who build these cars.

Smokey Yunick built more than one car with a claimed 100+ mpg capability. Prior to his death he was working on a K-car posting 150 mpg with a 13 second quarter mile capability.

Pure Oil Company used to run an economy run on a regular basis resulting in cars going 300+ miles on a gallon of gas. Among the many tricks used by the entrants were skinny tires with 100 psi of nitrogen, extreme drive ratios, reduced weight (minimum oil/water levels), body skirting and lowered suspensions. A few years ago my uncle gave me a bunch of 1960s Popular Science magazines featuring this event.

More recently I read of several folks who routinely get 70+ mpg on mostly stock cars by using driving techniques that would irritate most drivers unlucky to follow them. These guys anticipate stoplights by easing off the gas and coasting, drive on the painted shoulder line (to gain a smoother surface on the right wheels) and accelerate at tortoise-like rates.

Most of us can easily get better mileage (even in our Broncos) but it takes a dedicated change in driving habits.

You know it on the driving tricks

When I used to drive the old style Minis I used to gently increase speed before a hill and coast up and over, then lightly accelerate down the hill to get back up to speed.

I tried to never do that in front of other cars as that would drive them just about crazy, unlike my Brother who just didn't give a $h!t anyway:histerica

Like I said he could squeeze a pile of mpgs out of a gallon, far more than they were rated for (the Minis).

We very quickly ditched the 850s, 997s, 998s, 1100s for the "big block" Mini engines (1275ccs) as we found you needed "enough" power to increase your mileage.

We were no Smokey Yunicks I can assure you, but with our Mini club we got some very serious performance and mileage increases out of engines designed in the 30s.

Just imagine what engineers could do if we'd buy the cars they'd create(backing up your point Can).

The first thing that came to my mind about that car was the chain drive and at what speeds they achieved this number. I completely believe its possible, however, is it realistic to have a car like this on todays roads?

I don't think I would trust the mechanism by which they switch between the gears. I've had unreliable 10 speed bicycles that used similar technology. And of course, never mind the fact it looks REALLY uncomfortable to drive.
