The 2019 GMC Terrain AWD with the 1.6L diesel engine gets 32 MPG combined, avoiding the usual fuel economy penalty associated with all-wheel drive in a compact SUV. This number appeals to a specific buyer: someone who needs AWD for occasional inclement weather, but also wants efficient everyday driving. This Terrain caters to a practical mindset, delivering a blend of capability and frugality that’s often hard to find.

City and highway performance

The EPA estimates show where the Terrain AWD excels. The 28 MPG city rating is competitive within its class, suggesting respectable fuel consumption during stop-and-go driving, a common scenario for suburban commutes. The 38 MPG highway rating is a real standout. This figure, achieved thanks to the diesel engine’s inherent efficiency at steady speeds, positions the Terrain as a strong choice for those who frequently embark on longer journeys. While perhaps not the most modern design, the six-speed automatic transmission is well-matched to the engine’s torque curve, contributing to smooth acceleration and relaxed highway cruising.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2019 GMC Terrain AWD 1.6L diesel at $1,750. This estimate is based on driving 15,000 miles per year and using national average fuel prices. It’s a standardized metric designed to allow consumers to directly compare the predicted cost of fueling different vehicles. Individual driving habits and local fuel prices will influence the actual cost, but this figure provides a benchmark for assessing the Terrain’s long-term running expenses. Buyers should also consider that diesel fuel prices can fluctuate, impacting the real-world cost.

Real-world expectations

The EPA provides valuable data, but real-world MPG may vary. Driving style is a significant factor. Aggressive acceleration and excessive speeding will decrease fuel economy, while a more conservative approach will bring you closer to the EPA estimates. Terrain, weather conditions, and tire pressure also play a role. However, drivers who want better fuel efficiency and adopt sensible driving habits should expect to see numbers reasonably aligned with the EPA ratings. Remember to check TERRAIN MPG across all years to see the historical data.

How it compares

Several competitors offer AWD compact SUVs, but few achieve the same fuel efficiency as the diesel-powered Terrain. The Toyota RAV4 AWD, a popular choice, typically delivers around 30 MPG combined. The Honda CR-V AWD achieves similar numbers. The Mazda CX-5 AWD, known for its sporty driving dynamics, lands in the mid-20s. Even hybrid competitors like the RAV4 Hybrid AWD may not significantly exceed the Terrain’s highway MPG, though they will likely outperform it in city driving.

The Terrain’s diesel engine provides a unique advantage in highway fuel economy, important for buyers who want long-distance efficiency.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy, especially with a diesel engine. Avoid stomping on the accelerator pedal, and gradually increase your speed. Keep an eye on the tachometer and try to shift smoothly, allowing the engine to operate in its most efficient range.

Regular maintenance is crucial for maintaining optimal fuel efficiency. Ensure that your tires are properly inflated to the recommended pressure, as underinflated tires can increase rolling resistance and negatively impact MPG. Scheduled oil changes and air filter replacements will also help the engine run smoothly and efficiently.

Minimize idling time whenever possible. Letting the engine run while stationary consumes fuel without contributing to your mileage. If you anticipate being stopped for more than a minute or two, consider turning off the engine.

Reduce aerodynamic drag by avoiding unnecessary roof racks or cargo carriers. These accessories can increase wind resistance and decrease the vehicle’s fuel economy, particularly at higher speeds.
