2010 Silverado and Sierra XFE Models Get 22 MPG Highway
Last year, General Motors and Ford responded to high fuel prices and consumer demand for more fuel-efficient pickup trucks by rolling out new "fuel efficiency" crew-cab models. The Chevrolet Silverado and GMC Sierra XFE twins and Ford F-150 SFE were all rated at 15/21 mpg city/highway. For 2010, GM is breaking the tie.
Ford has kept the gas mileage numbers but dropped the XFE label from the 2010 F-150 lineup while GM continues to wring efficiency from its XFE rigs. The result: Non-XFE Silverado and Sierra crew cabs with 5.3-liter V-8 engines are now rated at last year's 15/21 mpg while the latest XFE trucks gain an extra 1 mpg on the highway, to 15/22 mpg city/highway. That's the same highway figure as GM's full-size hybrid pickup trucks. The bump in gas mileage also boosts combined city/highway fuel economy ratings from 17 mpg to 18 mpg.
Chevrolet spokesman Brian Goebel says that engineering refinements helped GM achieve the XFE's improved numbers.
"We've enhanced the trucks' fuel-saver mode, which optimizes shift patterns in the six-speed transmission for the best fuel economy. Also, Active Fuel Managment [which automatically operates the engine in four-cylinder or eight-cylinder modes depending on load to save fuel] is now able to hold four-cylinder mode longer. Plus, we've added variable valve timing to the engine."
