Traditionally, automakers only make small changes on models year-to-year, only truly changing the cars with their publicized “redesigns.” However, sometimes automakers make small tweaks to increase a car’s appeal, as they have been doing lately in attempts to improve gas mileage.

Fuel economy has become an important consideration for consumers looking to save at the pump. With that in mind, some automakers are making slight changes to their vehicles in order to improve their EPA-rated mileage, according to the Associated Press.

Honda, for example, has made some slight changes to its popular Accord model for the 2011 model year. Changes to the car’s aerodynamics, gears, and engine friction have increased mileage from 31 to 34 miles per gallon on the highway and 21 to 23 in the city. That puts it in second place of the midsize models for fuel economy, trailing the Hyundai Sonata’s 35 mpg.

Chrysler has also announced plans to make similar changes to its Sebring and Dodge Avenger models, promising large increases to their current ratings of 21 city/30 highway miles per gallon.

Those looking to save money might want to look at fuel efficient used cars, as they will save money not only at the pump, but also at the dealer.
