Automaker Previews New, More Efficient Four and Six Cylinder EnginesWith so much on the line and even more to prove to consumers, General Motors has previewed its latest in fuel-saving technologies for the upcoming 2009 and 2010 model years. As is the case with other manufacturers, GM has chosen to go the most cost effective direct injection (DI) route to up EPA estimated mpg fuel ratings, decrease emission outputs, and maintain sufficient power in its future vehicle lineups. The highlight of GM's DI surge will be a pair of engines -- a 2.4L four-cylinder and 3.0L V-6 -- set to debut at next month's Detroit auto show under the hood of the 2010 Chevrolet Equinox.
