21 MPG combined isn’t going to win any fuel efficiency awards, but for the 2018 Chevrolet Traverse FWD with the 3.6L V6, it’s a workable compromise for buyers who prioritize space, practicality, and value over outright fuel savings. This isn’t a vehicle designed for hypermilers. It’s built for families hauling kids, cargo, and the occasional small trailer. Understanding that mission is key to understanding the Traverse’s appeal.

City and highway performance

The EPA estimates the 2018 Traverse FWD at 18 MPG in the city and 27 MPG on the highway. The city figure reflects the stop-and-go driving that plagues many suburban commutes. The 3.6L V6, while reliable and strong, needs to work harder in these conditions, impacting fuel consumption. However, the 27 MPG highway rating is more respectable, demonstrating the benefits of the 9-speed automatic transmission which allows the engine to cruise at lower RPMs at higher speeds. Drivers who do a significant amount of freeway driving will see mileage closer to this figure, while those predominantly in urban environments should temper their expectations.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Chevrolet Traverse FWD at $2,100. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. This cost is a good benchmark, but individual expenses will vary depending on local fuel prices, driving habits, and the actual mix of city versus highway driving. Someone who primarily drives highway miles and avoids rush hour could realistically spend less, while a driver stuck in gridlock every day could easily exceed this annual estimate.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy often differs. Factors like driving style, terrain, weather conditions, and even tire pressure affect mileage. Aggressive acceleration and hard braking can significantly decrease fuel economy. Carrying heavy loads or towing will also reduce the Traverse’s MPG. Regular maintenance, including air filter replacement and proper tire inflation, is critical to maintaining optimal fuel efficiency. Some drivers report exceeding the EPA combined estimate on long road trips, while others struggle to reach the city figure due to consistent short trips and idling.

How it compares

The 2018 Traverse competes in a crowded three-row SUV segment. The Honda Pilot, for instance, offers similar space and practicality but generally achieves slightly better mileage. The Pilot’s FWD models with the 3.5L V6 and 6-speed automatic earn an EPA rating of 22 MPG combined. The Toyota Highlander, another popular choice, also edges out the Traverse, with its FWD V6 models rated at 21 MPG combined. Even the Ford Explorer with its base 2.3L EcoBoost engine can achieve similar fuel economy to the Traverse’s V6, though it offers a different driving experience. These fractional differences matter to buyers cross-shopping these vehicles, particularly those who prioritize fuel efficiency. See TRAVERSE MPG across all years for additional comparisons.

Tips to maximize efficiency

Avoid aggressive acceleration. The Traverse’s 3.6L V6 is responsive, but burying the throttle consistently will take a toll on fuel economy. Smooth and gradual acceleration will help keep the engine in its more efficient operating range. Use cruise control on the highway to maintain a constant speed and minimize unnecessary fluctuations in throttle position.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the pressure listed on the sticker inside the driver’s side doorjamb. This is important when carrying heavy loads.

Minimize idling. Idling consumes fuel without moving the vehicle. If you’re stopped for more than a minute, consider turning off the engine. However, be mindful of restarting frequently in very short intervals, as the starting process itself consumes some fuel.

Reduce unnecessary weight. Carrying excessive cargo adds weight, increasing the engine’s workload and reducing fuel economy. Remove any unnecessary items from the vehicle, particularly heavy objects. Even small weight reductions can cumulatively improve efficiency over time.

Stick to regular maintenance. Keeping the engine properly tuned and ensuring all components are functioning optimally is crucial for achieving good fuel economy. Follow Chevrolet’s recommended maintenance schedule for the Traverse, including oil changes, air filter replacements, and spark plug replacements.
