The 2017 GMC Terrain FWD with the 3.6L V6 engine gets an estimated 20 MPG combined. This isn’t going to win any awards as hybrid and electric SUVs become more common. The Terrain, in this configuration, fits a buyer who wants power and a smooth driving experience more than saving gas. It’s for those who like the confident acceleration and easy highway driving that a V6 engine offers, even if it means stopping at the gas station more often.

City and highway performance

The EPA estimates for the 2017 Terrain V6 FWD are 17 MPG in the city and 24 MPG on the highway. The city number shows the effects of stop-and-go driving and idling. The Terrain’s weight and the V6’s fuel consumption in these conditions affect this number. However, the 24 MPG highway rating is better. Out on the open road, with less stopping and starting and at consistent speeds, the V6 gets into a more efficient mode. The six-speed automatic transmission also helps consumption at higher speeds, keeping the engine at its best.

Annual fuel cost

The EPA says you’ll likely spend about $2,200 in annual fuel costs for the 2017 GMC Terrain V6 FWD. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price. This is only an estimate, and your actual fuel costs may change based on your driving, local fuel prices, and the amount of city versus highway driving. If you drive mostly in busy city areas, expect that $2,200 number to increase.

Real-world expectations

The EPA estimates are a starting point, but your actual mileage may be different. Hard acceleration, frequent short trips, and heavy loads can all hurt fuel economy. But smooth acceleration, consistent speeds, and good maintenance can help you get closer to the EPA numbers. The 3.6L V6 is known for encouraging drivers to use its power, so trying to drive in a way that saves gas should be a priority. Don’t expect hybrid-like fuel economy, but reasonable results are possible if you make an effort to save gas.

How it compares

The 20 MPG combined rating puts the 2017 GMC Terrain V6 FWD in a specific place among compact SUVs. For example, the 2017 Honda CR-V with its 1.5L turbo engine gets 30 MPG combined in FWD configuration, which is much better. The Toyota RAV4, similarly equipped, gets about 26 MPG combined. Even a larger SUV like the 2017 Ford Edge with its base 2.0L EcoBoost engine gets around 24 MPG combined. Buyers who choose the Terrain V6 are trading some fuel efficiency for the extra power and responsiveness that the V6 provides, which is a good choice for those who often tow small trailers or want strong passing performance.

Tips to maximize efficiency

Check your tire pressure. Underinflated tires increase rolling resistance, which makes the engine work harder and uses more fuel. Keep your tires at the correct PSI, usually found on a sticker inside the driver’s side doorjamb, to see an immediate and real impact, especially on long highway trips.

Avoid fast acceleration and braking. The Terrain’s V6 is responsive, but pressing the gas pedal hard and braking suddenly uses more fuel. Accelerate smoothly and gradually, and watch traffic so you don’t have to brake as much. These habits will save fuel and extend the life of your brake pads.

Reduce idling. Modern engines are made to be efficient when running, even when stopped. However, idling wastes fuel. If you’re going to be stopped for more than a minute, think about turning off the engine. This is especially important if you drive in stop-and-go traffic.

Service the vehicle as recommended. Regular maintenance, like oil changes, air filter replacements, and spark plug replacements, keeps the engine running at its best. Not doing these services can cause lower performance and higher fuel consumption. Follow the manufacturer’s service schedule.

Consider the weight you’re carrying. Extra cargo weighs the vehicle down, using more fuel. Take out anything from the trunk or backseat that you don’t need every day. This small step can make a difference over time. For more information check all Gmc fuel economy data, and the TERRAIN MPG across all years.
