26 MPG combined. That figure follows the 2016 GMC Terrain FWD 2.4L, not because it’s terrible, but because it represents a compromise most Terrain buyers have already accepted. This isn’t a vehicle purchased for its exceptional fuel efficiency; it’s chosen for its styling similar to trucks, relatively compact size, and a premium feel within GM’s offerings.

City and highway performance

The EPA estimates for the 2016 Terrain’s 2.4L engine in front-wheel-drive configuration break down to 22 MPG in the city and 31 MPG on the highway. The city figure is more relevant, as the Terrain is often used in cities, hauling kids, groceries, or for commuting. The highway number is adequate, but it’s unlikely to be consistently achieved unless you maintain a steady speed and avoid aggressive acceleration. This engine needs to work hard to move the Terrain, especially when loaded with passengers or cargo. Drivers with a heavy foot will see both figures decrease.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 GMC Terrain FWD with the 2.4L engine is $1,700. This calculation assumes 15,000 miles of driving per year, with a mix of city and highway miles mirroring the EPA’s testing. It is also based on national average fuel prices, which can vary depending on location and market conditions. Some drivers may exceed this cost if they drive more than 15,000 miles annually or live in areas with higher fuel costs. Others who predominantly drive on the highway, or are careful with the accelerator, could potentially spend less. To see all Gmc fuel economy data, you can browse our comparisons.

Real-world expectations

The EPA figures provide a benchmark, but understanding the Terrain’s performance in the real world is important. Many owners report achieving numbers close to the EPA’s estimates under good conditions. Factors such as driving style, weather, tire pressure, and vehicle maintenance play a role. Expect lower MPG in cold weather due to winter blend fuel and increased engine friction. Towing, even small trailers, will greatly reduce fuel efficiency. Aggressive acceleration and frequent braking in stop-and-go traffic also hurt MPG. A properly maintained engine, with clean air filters and correctly inflated tires, is essential for maximizing efficiency.

How it compares

In 2016, the Honda CR-V, a key competitor, offered better fuel economy, achieving around 29 MPG combined in its front-wheel-drive configuration. The Toyota RAV4 also consistently outperformed the Terrain, often reaching the same 29 MPG. The Ford Escape, with various engine options, could achieve similar or slightly better mileage depending on the engine. Even the Nissan Rogue, known for its focus on fuel efficiency, was typically ahead of the Terrain in real-world MPG. If fuel consumption is a primary concern, these alternatives are good choices. However, the Terrain appeals to buyers who want its styling and interior, even with slightly lower MPG than its rivals. For users seeking the very best TERRAIN MPG across all years, they should consult fuel logs and owner’s groups and seek out the most consistently efficient versions.

Tips to Maximize Efficiency

Gentle acceleration is key to optimizing fuel economy in the 2.4L Terrain. Avoid sudden bursts of speed and allow the vehicle to gradually build momentum. This engine is not powerful, so resisting the urge to floor the accelerator, especially when merging onto highways, will yield savings.

Maintain a steady speed on the highway whenever possible. Cruise control helps prevent speed fluctuations that can negatively impact MPG. Wind resistance increases greatly at higher speeds, so even small reductions in speed can make a difference over long distances.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate to the recommended pressure listed on the driver’s side doorjamb.

Regular maintenance is essential for fuel economy. Keep your engine properly tuned, replace air filters as recommended, and use the recommended grade of motor oil. A well-maintained engine runs more efficiently and consumes less fuel.

Reduce unnecessary weight in the vehicle. Hauling around extra cargo adds to the vehicle’s weight, which decreases fuel efficiency. Remove any unnecessary items from the trunk or cargo area to lighten the load and improve MPG.
