Just a note - the reason that small diesels are not popular here is because of the California Air Resources Board's idiotic measurement methods.
They count total emissions not per-mile, but per-gallon, completely ignoring that the diesel-powered vehicle will go farther on the same amount of fuel.
- boredguy8 18y agoI can't find a source saying how they measure in either direction. Link? Thanks!
- gleb 18y agoBy far the biggest reason that car diesels are not popular in US, while they are popular in Europe, is that diesel fuel is taxed similarly to gas here. In Europe it enjoys significant tax advantage. A small contribution is bad experience consumers had with GM's diesels 1978-1985, which were a poor product. I also really don't get the obsession of mpg, when comparing different fuels. Diesel is about 30% more energy dense than gas. If I told you that the car got 100mpg on coal (which has even higher energy density) would that be exciting?
- anamax 18y agoHuh? That would be a pass for cars that use more gas. The federals standards are grams per mile. CA's testing facilities use parts per million gauges, but the threshold is model-specific so the readings can be used to identify grams per mile violators.
