Two of Honda's most fuel-efficient cars, the Insight and Fit, differ. The Insight, a gas-electric hybrid, is rated at 38 miles per gallon. But at a sale price of $18,970, it would take seven years to make up the price and operating cost premium over the Fit, which sells for $15,870 and is rated at an average 30 miles per gallon. If gasoline were to rise in price to $4.75 a gallon, then the Insight would make a bit more fiscal sense, as its payback period would drop to five years.
