2010 Subaru Legacy - Click above for a high-res image gallery

The 2010 Legacy will be the most fuel efficient Subaru in the Japanese automaker's US lineup, but only when it's powered by the 2.5i boxer engine mated to a CVT transmission. According to the EPA, that powertrain returns 31 mpg on the highway, a full four mpg better than the six-speed manual. With fuel economy standards set to climb over the next decade, Subaru is going to need more mpg success stories, and more CVTs could be a big part of the equation.

Japan's Nikkei Sangyo business daily reports that Subaru will flood its product lineup with CVTs over the next two years, starting with the popular Forester and Impreza models. The CVT, which is made at Subaru's engine plant in Oizumi, will eventually be offered on all models.

While the CVT is new for larger Subarus, the company has been using the transmissions in JDM city cars since 1987. Last week, Subaru began using a CVT in its Japan market Exiga MPV, which will soon be extended to the Australian market.
