What ever happened to the Energy Department's 100 MPG(e) production car?

Thought experiment. Which is more effective in reducing carbon emissions, raising gas mileage from 20 to 35 mpg or raising it from 35 to 100?

The first reduces usage by 2.14 gallons/100 miles, while the second by only 1.86. This is why the European usage of liters/100km is a more useful way to measure fuel economy.

Well, there’s nothing special about liters or kilometers that makes it more useful. The US would be better off using gallons / 100 miles.

Of course. I thought that was implicit in what I actually posted. But if they ever go metric…
