Fuel Saving Tips

Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible.

 

1. Avoid fast starts and accelerate smoothly.

 

2. Brake gradually and avoid abrupt stops.

 

3. Avoid idling the engine for long periods of time.

 

4. When road and weather conditions are appropriate, use cruise control.

 

5. Always follow posted speed limits or drive slower if conditions require.

 

6. Keep vehicle tires properly inflated.

 

7. Combine several trips into a single trip.

 

8. Replace the vehicle's tires with the same TPC Spec number molded into the tire's sidewall near the size.

 

9. Follow recommended scheduled maintenance.

FUEL ECONOMY OVERVIEW

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.

GMC Vehicles

Our Professional Grade engineering has helped produce these benefits:

• No competitor has better V8 fuel economy than the GMC Sierra.2

 

• Multiple fuel saving technologies work together to make the GMC Sierra Hybrid the most advanced full-size pickup available today.3

 

• The Sierra Hybrid has best in class V8 fuel economy.4

 

• The GMC Yukon has better fuel economy than any other competitor.5

 

• The GMC Yukon Hybrid has best in class fuel economy.6

 

• Acadia : GMC was the first to offer an 8-passenger SUV with an EPA estimated 24 highway miles per gallon.7

 

• Terrain : Best-In-Class standard highway fuel economy.8

 

• With a large fuel tank capacity and standard EPA est. 32 mpg hwy fuel economy, Terrain offers the best hwy cruising range of any SUV in its class.9

FUEL EFFICIENT VEHICLE BENEFITS

Upgrading to a more fuel-efficient vehicle is a worthwhile investment. Better fuel efficiency optimizes fuel range and reduces stops at the pump.

 

• If you drive 15,000 miles per year, you could save up to $990 in fuel costs in one year simply by trading in your 20 MPG hwy car for a 32 MPG hwy GMC Terrain. Save $4,950 after five years. (Gas prices based on $3.52/gal for 2/13/12 ; annual 15,000 miles http://www.eia.gov/oog/info/gdu/gasdiesel.asp)(15,000/20 x 3.52) – (15,000/32 x 3.52) x 5= 4,950)

 

• Terrain offers a 600 mile highway driving range. That’s 300 miles more a fill up!

 

• You would make 25 fewer stops at the gas station.

 

GMC has engineered a variety of fuel-efficient vehicles with:

 

• E85 fuel and two-mode hybrid capabilities and other GMC fuel-efficient technologies, which are constantly improving.

 

• Fuel technologies, which optimize automotive energy efficiency and include both engine and vehicle applications.

 

• Innovative technologies that allow newer engines to achieve more power as well as better fuel efficiency.

 

• Engine innovations, including cylinder deactivation and turbochargers that increase power by compressing and decompressing gases within the engine.

 

• Direct fuel injection, which is a process that requires the injection of highly pressurized gasoline directly into the combustion chamber and also improves engine efficiency. GMC Terrain and Acadia both utilize Direct Injection technology. GMC Sierra HD uses the available Duramax Diesel that uses both Direct Injection and a turbocharger.

ACTIVE FUEL MANAGEMENT

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.

SIERRA XFE – XTRA FUEL ECONOMY

Sierra XFE Badge

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:

  • No competitor offers a V8 with over 300 hp and over 21 highway miles per gallon like the GMC Sierra XFE. Not Toyota Tundra. Not Ford F-150. Not Ram 1500. 11
Sierra XFE Crew Cab

The following are incorporated on the Sierra XFE model to help maximize fuel economy:

• Durable 5.3L FlexFuel V8 engine with Active Fuel Management
• Improved aerodynamics with a soft tonneau cover to reduce drag in truck bed
• Revised chassis tuning
• Extended front lower air dam
• Aluminum lower control arms
• 17-inch aluminum wheels

BUILD YOUR OWN

E85 FLEX FUEL

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.

E85 FlexFuel

E85 Advantages

  • Mostly renewable resource made primarily in the US, reducing use of imported petroleum
  • Lower emissions of air pollutants like Carbon dioxide
  • More resistant to engine knock
