General Motors (GM) reports that it is the first American brand to sell more than 1 million vehicles in the U.S. with a fuel economy rating of more than 30 miles per gallon or higher for highway driving. The automaker managed to offer a variety of models that fit in the spectrum of fuel-efficient vehicles, including smaller car sizes, hybrid technologies and new engines.
Just because GM has hit its stride with fuel-efficient models doesn't mean it will sit back and rest on its laurels. The manufacturer has plans to introduce new cars that will feature smaller frames and the least amount of vehicle maintenance possible, The Wall Street Journal reports.
"Our investments in advanced powertrains are clearly paying off, and our smaller vehicles are resonating with customers," said Mark Reuss, president of GM North America. "In 2013, we'll introduce new diesel, eAssist and plug-in vehicles in the U.S. and expand the availability of turbocharged four-cylinder engines."
According to AutoBlog, sales of GM's mini-, small- and compact-car models increased by 39 percent in 2012, with many of the most popular models, such as the Chevrolet Malibu, Cadillac ATS, Buick Verano and GMC Terrain, boasting 30 or more miles per gallon.
