Summer's here, and while top-down motoring is fun, convertibles can be thirsty cars. So on with our list of the top 10 fuel-efficient convertibles by annual fuel cost. We started with the EPA's annual fuel cost ratings, which reflect the current national average gas price and assume 15,000 miles traveled annually, divided between 55 percent city and 45 percent highway. We picked the highest-mileage transmission choice available in a given car. When annual fuel cost was the same, we looked for a net gain between city and highway efficiency, and ultimately used our star ratings – a quick look at our opinion on each vehicle – as a tiebreaker.
