2005 Toyota Camry
While listing the Chevrolet Impala in a top ten fuel economy list may raise some eyebrows, including the Toyota Camry probably won’t. When fitted with the 2.4-liter four-cylinder engine and the five-speed automatic transmission, the Camry achieves 34-mpg (ironically, when connected to the five-speed manual transmission the rating drops to 33-mpg), provides 102 cubic feet of passenger volume and starts at about $18,500 (base model with the optional automatic transmission).
