The 2018 GMC Terrain FWD 1.6L diesel gets 32 MPG combined, which is a key selling point for buyers who want good fuel economy in a compact SUV. This Terrain prioritizes a comfortable ride and a stylish exterior over fast acceleration or off-road capability, and it offers lower fuel costs. It’s a good choice for commuters, small families, and empty-nesters looking for an efficient and practical vehicle for daily driving and occasional road trips.
City and highway performance
The Terrain’s 28 MPG city rating is a real benefit for drivers in stop-and-go traffic. The diesel engine’s strong low-end torque helps with smooth acceleration, which minimizes wasted fuel. On the highway, it gets 39 MPG. This makes the Terrain a smart choice for longer commutes and road trips because it saves money on gas and requires fewer fill-ups.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2018 GMC Terrain FWD 1.6L diesel at $1,750. This is based on 15,000 miles per year, a mix of city and highway driving, and national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and local fuel prices. Aggressive driving and high speeds will impact this estimate. Checking all Gmc fuel economy data can provide more information, but $1,750 is a useful benchmark for comparing costs.
Real-world expectations
EPA estimates provide a baseline, but real-world fuel economy varies. Weather, driving style, and vehicle maintenance matter. If you drive conservatively, maintain your vehicle, and drive mostly on the highway, expect numbers close to the EPA estimates. More aggressive driving or frequent short trips in cold weather can reduce your MPG. The best way to know is to monitor your own fuel consumption.
How it compares
The 2018 GMC Terrain FWD 1.6L diesel compares well to competitors without hybrid powertrains. A comparable Honda CR-V with a standard gasoline engine gets around 28 MPG combined. The Toyota RAV4 gets similar MPG. Even newer versions of these vehicles without hybrid technology may not reach the Terrain diesel’s 32 MPG combined. The Terrain’s diesel engine is good for buyers who want to maximize fuel efficiency but aren’t ready for hybrid or electric vehicles. Examine TERRAIN MPG across all years for more details.
Tips to maximize efficiency
Gentle acceleration and smooth braking are crucial for maximizing fuel efficiency. Avoid sudden bursts of speed and anticipate traffic to minimize hard braking. Less aggressive use of the engine is ideal.
Proper tire inflation affects fuel economy. Check your tire pressures regularly and keep them at the recommended levels on the door jamb sticker. Underinflated tires increase rolling resistance and force the engine to work harder.
Regular maintenance, like oil changes and air filter replacements, helps your Terrain run efficiently. A clean air filter helps airflow to the engine, and fresh oil reduces friction. A well-maintained engine is an efficient engine.
Keep idling time to a minimum. Modern engines restart more efficiently than they idle for long periods. If you’re stopped for more than a minute, turn off the engine to save fuel. This applies to all kinds of driving.
