The engineers from General Motors have miraculously managed to improve the Chevrolet Cruze’s fuel economy by an additional 2 mpg. The Chevy already has a Cruze Eco option that delivers 28 mpg city, 42 mpg highway when fitted with the six-speed manual transmission.
For the 2012 model, Chevrolet has bumped the highway mileage rating of the Cruze model with 1.4-liter engine and an automatic transmission to 38 mpg, a gain of 2 highway mpg over last year’s EPA ratings of 24 mpg city, 36 mpg highway for that same combination.
This 2 mpg increase was attained through lowering the final-drive ratio to 3.53 from 3.87 in the current year’s model. This allows the engine to run at a lower speed burning less fuel. The Cruze is capable of hitting 40-mpg on the highway however buyers will need to order the extra-cost Eco model for that.
