It all adds up: Mazda3 makes an impact with its fuel economy

Some numbers mean more than others. They're magic numbers. Electoral votes? 270. Black jack? 21. A compact car's miles per gallon? 40.
Welcome to the club, Mazda.
The 2012 Mazda3 reaches the benchmark, thanks to its new SkyActiv engine. Although the model offers four engines in all, it's the rookie, a 2.0-liter 4-cylinder, that hits the target.
The SkyActiv engine with a 6-speed automatic transmission has Environmental Protection Agency mileage ratings of 40 mpg on the highway and 28 mpg in the city. They represent an increase of 7 mpg highway and 3 mpg city over the numbers produced by the base 2.0-liter, 4-cylinder engine, which did not have the SkyActiv engine.
Mazda has taken advantage of the car's lightweight materials. The Mazda3 checks in at 2,896 pounds, so the fresh technology results in a net gain.
Mazda3s come in sedan and hatchback, and all are front-wheel drive
