Together with a
slight improvement in drag (its coefficient drops one hundredth to 0.30; the Camry's is 0.28) and a
slight reduction in weight — as much as 78 pounds, depending on trim — the new 2013 Altima
posts big gains in EPA fuel economy: the city rating jumps from 23 mpg to 27 mpg, and highway mileage goes from 32 mpg to a top - of - the - class 38 mpg.
