If it's an engine with more than four cylinders, Volvo doesn't want it in its lineup. Within the next 10 years, the Swedish automaker plans to eliminate any engine options greater than four cylinders in an effort to reduce fuel consumption and C02 emissions. No more five- and six-cylinder mills. In their place, Volvo will employ three- and four-cylinder units in both gasoline and diesel form.

The new engine family is called Volvo Environmental Architecture (VEA), and the automaker says the new powertrains will be nearly 200 pounds lighter than its current engines. In addition, the new mills will improve fuel economy by 35 percent. That will be an impressive boost, and Volvo believes it can accomplish this feat without a reduction in performance.

The 1.5-liter three-cylinder and 2.0-liter four-cylinder engines will start to make their way into production models by 2013. By 2020, the entire lineup will be filled with them.
