cars.com— “We’ve devised an efficiency-cost rating to reflect efficiency bang for your overall buck. It’s simply combined city/highway mpg divided by the base MSRP. We then multiplied that number by 1,000. This formula can be applied to any vehicle type, hybrid or not. Higher mpg ratings and lower prices yield higher rankings. We do account for federal tax incentives, but not for equipment levels, quality judgments, cost of ownership or any inaccuracies in EPA mileage estimates.” A higher Efficiency – Cost Rating translates to a better vehicle ranking.
