Anything that boosts fuel economy on a vehicle is likely to get a big thumbs up from the consumer market these days.
Anything that boosts fuel economy on a vehicle is likely to get a big thumbs up from the consumer market these days, therefore a move by General Motors to launch fuel saving versions of 2009 Chevy Silverado, Chevy Tahoe, GMC Sierra and GMC Yukon is surely a good thing.
The models carry the label XFE – meaning Xtra Fuel Economy and now carry EPA-rated fuel economy figures of 15 City and 21 highway mileage ratings, up from 14 and 20 respectively on the non-XFE models.
The full sized pickups are powered by a 5.3L FlexFuel V-8 (LC9) engine that’s built with a mass-reducing aluminum cylinder block and heads. Power output lies at 320hp(238 kW) and 340 lb-ft of torque (461 Nm) in the Tahoe and Yukon and 315 hp(235 kW) and 338 lb-ft(458 Nm) in the Silverado and Sierra.
Further fuel savings are achieved with improved aerodynamics - the Silverado XFE and Sierra XFE feature an extended front lower air dam and soft tonneau cover whilst all models benefit from lowered suspension and revised chassis tuning. Overall weight is also reduced with aluminium 17 or 18 inch wheels.
