This is why only dingdongs believe that the oil industry bought up special 100mpg carburators. There is only so much energy in a gallon of fuel and it's going to take x amount of energy to move a weight down the road.

I haven't had the 1800, but I like Jose Cuervo Tradicional Anejo, which is 100% agave. It's pretty good, especially for the price.

Should try this in real life - go to a bar and say “gimmie a beer” and when they say “what kind” just keep pushing back on “just gimmie a beer”. lol

Silly? Languages don't really have strict rules on naming things. Why use petrol for gasoline? There are a lot of petroleum products, but we only burn a couple specific formulations in cars.

>You just don't see such 'city cars' in the USA because no red-blooded meat-eating christian would buy such a silly little vehicle.
I'm taking a guess you're european and have no clue why cars are different in the US. We do have those cars, but commutes on average are at minimum twice as long as European counterparts. I don't think Europeans have ever actually looked at a map or globe critically when they say garbage like this. They don't understand how big the US actually is and how much distance MORE a US driver travels. this is why they buy the larger more comfortable models mostly, which has lend to an escalating war of leg room, comfort, etc.

Hybrids are gas powered vehicles. They have electric motors powered by the engine that allow for better fuel efficiency and regenerative braking. My Prius gets 65 mpg on a good drive on the highway.
Edit: The same issue happens with the Prius though. The gas mileage isn't much better than the original. It's due to weight. The current Prius is over 300 pounds heavier.

Calling a liquid fuel gas is just silly.

Ok, it's commonly used in the US. Different countries use different words for different things.

There's a bit going on here.
Firstly, the US has a habit of buying big cars, and they've been getting bigger over time. If you add big, you add mass. If you add mass, you reduce fuel economy.
Second, regardless of the size of vehicles increasing, they've been getting heavier due to added structure for crash safety, additional safety systems, as well as added equipment in the vehicle.
Third, ignoring the way that fuel economy has been officially measured has changed over time (so you can't compare official figures separated by 20 years), traffic has increased which results in more stop / start traffic, which means worse fuel economy.
Edit:
I'll add a number 4:. Fuel costs by and large in the US over the last 20 years haven't been a major concern to consumers.
And 5: US federal policies haven't put major pressure on manufacturers to produce more fuel efficient vehicles until relatively recently. A lot of the rest of the world has spent the last 20 years pushing heavily towards reduced emissions, which has had a knock on effect of improved fuel economy.

I think the most recent production ICE engines are tending towards 45% efficiency, which is incredibly impressive.
Also people expect more gadgets these days - heated seats, steering wheels, computers and screens, AC in winter for dehumidification, and so on. All of these put more of a load on the engine.

Was trying to highlight the stupidity of using gas as an abbreviation for gasoline.

Do you meaning hydrogen combustion or fuel cells? Those are completely different processes.

I haven't the faintest idea what a US or UK gallon is so I leave that conversion to you. I'm just using the manufacturer's quoted figures, via wikipedia.
I can tell you that I only fill up my Citroën C1 4-5 times a year.

Kind of like how a horse can only run so fast no matter what you feed it.

Because they’ve maintained the same mileage but vastly increased performance and probably vehicle weight. The engines have become more efficient but they’ve offset that by incorporating more performance, options, and safety features. Pretty sure they could build a tin can that would get a 100 mpg at this point.

Check the horsepower and weight. I suspect the new car is heavier and more powerful while getting better mpg. Consider what they could do if the really wanted higher mpg.

Are you using UK mpg or American mpg?
Because, of course, those are different.
Doesn't change the argument, but makes it less mind boggling.
