GMC has engineered a lineup of fuel efficient SUVs, trucks and crossovers to accommodate this growing need by using new technologies and innovative thinking like Active Fuel Management, Hybrid Technology, Duramax Diesel Engines, and vehicles powered by alternative fuels like Ethanol/E85 Flex Fuel,1 Compressed Natural Gas (CNG) and Liquefied Petroleum Gas (LPG), available on 2010 or newer Savana Cargo models. Almost all 2012 Sierra models, 2010 or newer Yukon 1500 and Savana gasoline V8’s are capable of running on E85, except Hybrids.
Upgrading to a more fuel-efficient vehicle is a worthwhile investment. Better fuel efficiency optimizes fuel range and reduces stops at the pump.
GMC has engineered a variety of fuel-efficient vehicles with:
GMC trucks and SUVs are known for their power and trailering capacity to get the job done. To perform heavy-load tasks with optimal power and force requires an engine to use all cylinders pumping maximum amounts of air and fuel. This is efficient when towing a boat up a hill, but how does the engine adapt when the driving situation is 30 mph in the city without towing anything? Until GMC pioneered an engine technology referred to as variable displacement, large capacity engines would waste fuel consumption on lighter load conditions which do not require the full power of the engine.
Active Fuel Management is GMC’s process of variable displacement that turns off half the engine’s intake and exhaust valves. In a sophisticated computerized operation, GMC’s available 5.3L V8, 6.0L Hybrid V8 and 6.2L V8 engines10 seamlessly shift from eight to four cylinders temporarily when less power is needed thereby consuming less fuel. When the situation changes and you need more power, Active Fuel Management engages all 8 cylinders for maximum power.
When we designed the Sierra XFE model, improving gas mileage was our main objective and we looked at every part of our Sierra to find ways to get the best fuel mileage possible. Sierra XFE incorporates enhancements for fuel efficiency through the GMC 5.3L Vortec V8 engine, using lighter materials and streamlining the aerodynamics of the vehicle. The final results:
When it comes to gas mileage, Ethanol is a popular alternative source. Ethanol is an alcohol-based fuel made by fermenting and distilling starch crops, such as corn. It can also be made from trees and grasses. E85 is a blend of 85% ethanol and 15% gasoline and in some markets costs less at the pump than regular gasoline.
