Least fuel-efficient subcompact cars
Combined MPG from the bottom. A low figure is not automatically a bad buy — a three-quarter-ton pickup and a hatchback are not doing the same job — but it is the number that decides what a year of that job costs, which the cost column puts in dollars.

One row per nameplate, showing its best-rated version — a nameplate sold in six configurations would otherwise take six rows and push everything else off the page. Annual fuel is the EPA's own figure at 15,000 miles and its reference fuel prices; every model page recalculates it from your mileage and your prices. Where these come from.
