Anything major we do to our system will have to be done thru congress. Being as the lobbyists own congress and the lobbyists are the VERY wealthy entities, they will make sure they come out on top of any new legislation

So, you're saying it never happened?

Impossible to operate an automotive gasoline engine at 50% efficiency let alone 500% efficiency . Did you pass high school physics class ?

I own a 2010 BMW 335d. Easily breaks 40mpg on highway, and will dust a corvette. 425 foot pounds of torque. We're there.

Wife has a 2017 GMC Sierrra with the 420HP 6.2L , max Towing package with the huge mule deer mirrors. It has averaged 7.8L per 100km over 50Km at 90km speed. On low cost gasoline instead of the $$$ Diesel.

Here is the corvette you beat . 1977 Chevrolet Corvette C3 Production Statistics and Facts

Attended a partnership meeting of a Development group with over a billion in assets... one of the concerns is the President and CEO has built the company from inception over 30 years... there is no succession even with his two very bright sons as they have no interest in development or Real Estate in General... they both work for Elon Musk putting their Engineering and Physics degrees to work...

The car has been found that achieved 377 mpg:

Shell Oil's 377 MPG 1959 Opel - YouTube

Gasoline may have been (reformulated) and the vaporization has been reduced to the point that vapor carbs no longer are feasible. There was an interview with one of the Shell scientists years ago that was involved with this project but I have not been able to find it so far.

Also found a PR letter from Shell to an interested party, but the quoted mpg is (only) 297...

Do the math, such mileage would require over unity efficiency , doesn't occur.

I'll take your response as a yes, meaning you don't believe any of these experimental high efficiency vehicles ever existed, including this one:

So many conspiracies, so little time ...

That is all nice. But if the organizers of the race specify four seater car and the minimum speed of travel it will change very fast for way worse. Aerodynamic drag increses with square of speed while rolling resistance is linear. Therefore to double the speed of a vehicle you need to increase power eight times. Therefore energy consumption escalates very quicly with speed increase.
Example:
Bugatti Veyron:
1.) Small two seater sports car.
2.) With low aerodynamic drag C coefficent.
3.) 1200 HP engine.
4.) It needs all the 1200 HP to reach 431.072 km/h (267.856) mph drag limited.
From that we could estimate fuel consumption 0.17 miles/gal or about 4.5 miles to run the tank dry at maximum speed. If the vehicle had 100% efficeint power train it could travel about 20 miles to run the tank dry.

Great contribution!

Many just don't understand physics.

Same thing with draining the Tesla batteries. Speed UP, distance DOWN.

Regarding stuffing a big truck with batteries, isn't the purpose of the truck to transport goods? I suppose it would help reduce the hauling of crappy products (frivolous stuff ain't going to be transported due to the high[er] costs).

Most efficient transport is by ships: there has been many attempts to add wind power (sail) to them (to the future via the past!) The it's rail: and rail is run via hybrid diesel-electric. There really is nothing that provides the energy density of diesel (too bad that the limitations of IC engines couldn't be overcome).

I can transport myself plus 3,000 lbs of car 50 miles on 7.15 lbs of fuel (diesel). A tank of fuel gets me 750+ miles. But... the thread is really about transport of goods; POVs are going to be in decline (demographics [aging population], environmental and affordability). The ONLY way that we can approximate the same levels of goods movement with other-than-diesel power is with HUGE subsidies: yes, the existing fossil fuel based infrastructure is heavily subsidized; but, it also has a lot of embedded energy in it (much of the capital costs are covered- new stuff will be forced to not only compete with this fact but with the fact that we're all heavily in debt- the benefits of economies of scale aren't likely going to be coming in spades anymore).

Unless we're going to run trolley wire everywhere again (shame that nearly all the infrastructure got scrubbed) I'm not seeing electric as being able to deliver. In my more hopeful days I was an advocate for fusion energy; fusion, IMO, is the only thing that theoretically can meet the energy requirements for transport.
