The reasons better automotive technology didn't happen earlier in automotive history have been buried and lost to time, but we would be wise to not accept that it wasn't technologically or economically feasible.

Everyone has heard some version of this story: your grandma’s best friend’s sister’s boyfriend’s brother’s girlfriend heard from this guy who knows this kid whose dad was a garage genius. He worked some non-technical desk job, but experimented with engines on evenings and weekends. After much trial and error, he invented a special carburetor and his car got amazing miles per gallon.

If you know anything about older cars, this sounds like a dumb idea. A big engine needs a big carburetor to put in a bunch of air and fuel so that it can achieve a good fuel to air ratio and run right. But, ThunderHead289 knows his stuff a lot more than the average garage tinkerer, and figured out how to make it actually work and run right. The key? Advancing timing to put a spark to the less dense air-fuel mixture that the little carburetor would supply.

So, it’s entirely possible that something like this could have been pulled off in the 1960s-70s. Even if a garage inventor with limited technical skills couldn’t have pulled it off, automakers probably could have used their much greater resources to make a Maverick get 40-45 MPG on the highway.It turns out that there are some verifiable automotive experiments that got amazing mileage over the years, and with far better horsepower than the project above..

There's a reason every transmission has a different gear ratio despite weighing about the same. Or that the automatic transmission doesn't allow the car to coast, either foot on the gas or slowing down.
