Watch the movie: who killed the EV1. The big auto makers didn't give a **** about milage untill they were forced to by Ca. Then once GM had the car and Ca released the mandate they pulled all of them out of service. I'm sure there is technology out there, the big guys just haven't put money into developing it yet. I can't see a car geting 80 mpg with 400 hp. Maybe 7 out of the 8 cylinders shut off while you are on a perfectly flat road at 40 mph. I'm sure it's not too practical.

It's not in their best interest; there are exterior forces preventing this. Perhaps big oil is a big funder of car companies or maybe it's too hot out and I'm making up conspiracy theories? 
Don't forget that the ****ing Model T got 25 mpg with 1900s technology.
Fox body 5.0s got 15 mpg city. New Mustang GTs get 15 mpg city.
So...I understand there's a weight difference and all, but with a 20 year technology leap, they couldn't improve it one bit, even with a smaller, more efficient engine?
It's absolutely indisputable fact that vehicles overseas are much more efficient than ones here.

Gas mileage is a simple math equation that considers horsepower produced at a given level of efficiency. The modern mustang produces more horsepower for the same amount of gas being burned, sounds more efficient to me.
That guys claims sound like BS to me, I just want to see someone finish Smokey's Adiabatic motor.

The problem is that people think GM should care, when the problem lies with the people themselves.

what makes this guy think he can do what no other car company in history(and thousands of engineers) have been able to even come close to?
if its true he's going to be either really rich or really dead. for the time being i'm going to have to run my BS flag up the pole.

What makes you think the motors aren't "more efficient"???

Car companies are way behind, are they not? So 10 years ago, around the time of the EV1, oil was what, under 10 dollars a barrel? So why the hell would people buy hybrids, electric, etc. ? It's a catchup game.
Like I said before:
-Companies make super efficient cars for international markets.
-GM's Opel can get over 100 mpg in a diesel lightweight car.
-It's possible.
This is from my city's university:
Engineering students from the University of British Columbia (UBC), Vancouver did the unimaginable—they successfully defended their title for a fourth consecutive year at the international SAE (Society of Automotive Engineers) Supermileage Competition.

UBC Supermileage team members poses with their trophy following their victory in the 2006 SAE competition
This year over 40 teams from Canada, the U.S. and India registered to compete in the annual Supermileage student competition held in Marshall, Michigan, U.S. The goal of the competition is to design, build and drive a single person vehicle in the most fuel-efficient way possible. The vehicle must be powered solely by an internal combustion, gasoline engine with no assistance from electric motors or human propulsion.
The team’s top score this year was 3145 miles per gallon (0.074 litres/100 km)—far exceeding its expectation of reaching 2500 mpg. The demonstrated fuel-efficiency would make it possible to travel from Vancouver to Halifax on a gallon (3.79 litres) of gas, which would cost a little under $5 at the pump.

People, stop making excuses for the laziness of auto manufacturers.

Lets just clear something up right now: GM doesn't have to give a crap about mileage. They only have loyalty to the shareholders. Their job is to make money (which they aren't doing a great job of recently). To make money they build what sells. If there is enough demand them GM et al will build a super high mileage car. But given the past and even current price of gas it isn't worth the investment to pay the premium (needed to cover engineering costs) to buy a super mileage car.
The problem is that people think GM should care, when the problem lies with the people themselves.

Okay so the car is a dinky little junker. However, in practical terms with weight and the efficiency available, they can make it get an easy 100 mpg city, I have no doubt in my mind.

BS.
Not possible because of all the safety regulations and all of that bs. Now if it were like a moped or something like that and just for around town use i could see them easing up on some of the safety stuff and getting it a bit lighter. The milage teams start the motor, get up to speed and then coast for 75% of the course. I doubt the public would stand costing to a stop and then starting all over agin on the way home from work. I think a big problem is no one wants to sacrifice anything to get the better milage. The car is going to have to be smaller and have less power, something people think they can't do but for 95% of the people it would be fine.

I just think that it's funny that in the last 50 years, we have invented and developed things that would of been though impossible and today even blow my mind.... Yet, no one has been able to improve the internal combustion engine to have better gas mileage.....
Its just too crazy to think that they cannot do it.... Its that they just do not want to do it

I don't recall ever hearing about 300-400 horsepower cars in the late 60s and early 70's pulling down 25-30 highway miles per gallon while still making 0-60 in the 5.x second range and pulling 12's and 13's in the 1/4 mile.
