We are probably still at least a couple of decades away from economically feasible commercial vans and full-size trucks that are either directly powered by electricity or equipped with a fuel-cell stack that doesn’t cost its weight in gold, but it is still a pleasure to see even minor increments in fuel efficiency when it comes to vehicles whose main purpose in life is to help their owners earn a living. General Motors has just unveiled some official fuel economy numbers for their upcoming 2010 GMC Sierra and its twin brother Chevrolet Silverado. Powered by the same 5.3-liter V8 engine, both trucks will sport significant improvements in both city and highway driving cycles.
GM is about to start selling the fuel-sipping XFE (which stands for Xtra Fuel Economy) versions of its 2WD 2009 Chevy Silverado, Chevy Tahoe, GMC Sierra and GMC Yukon full size SUV’s and trucks that were designed to increase the brand’s competitiveness now when people finally start to count every penny in the face of the crisis that promises to be the worst in American history since the Great Depression.
A sweet pair of the new hybrid-powered 2008 GMC Yukon and 2008 Chevrolet Tahoe full-size SUV will be officially previewed at the soon to be opened 2007 State Fair of Texas.
