31 MPG combined is a respectable figure for the 2021 Buick Encore GX FWD 1.3L 3-cylinder, and it’s precisely what buyers in this segment are prioritizing: compact size, elevated seating, and reasonable running costs. It’s a competitive number for a vehicle designed to navigate urban landscapes easily while offering a touch of near-luxury refinement.

City and highway performance

The Encore GX’s EPA figures break down to 30 MPG in the city and 32 MPG on the highway. The city number reflects the stop-and-go driving where the GX excels. Its small displacement engine, coupled with the continuously variable transmission (CVT), is programmed to maximize efficiency in these conditions. The CVT ensures the engine is always operating within its optimal rev range.

The highway number is slightly higher, indicating efficient cruising at steady speeds, demonstrating that the GX is comfortable and economical on longer trips. Careful driving will easily match these numbers. See all Buick fuel economy data.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Buick Encore GX FWD 1.3L 3-cylinder at $1,400. This figure is based on driving 15,000 miles per year and national average fuel prices. This is a key data point for buyers budgeting their monthly expenses and see the Encore GX as a sensible, if slightly premium, alternative to more basic models. Buyers should remember that fluctuations in gas prices will directly impact fuel costs; a jump to over $5 per gallon nationwide would dramatically change this annual figure.

Real-world expectations

While EPA estimates provide a good baseline, real-world fuel economy can vary depending on driving habits, terrain, and weather conditions. Aggressive acceleration and frequent hard braking will negatively impact the Encore GX’s fuel consumption. And hilly terrains and cold weather conditions will reduce fuel efficiency. However, those who adopt a smooth and consistent driving style may find they meet, or even slightly exceed, the EPA estimates. The vehicle’s relatively light weight also allows it to maintain momentum better than heavier SUVs. Explore ENCORE MPG across all years.

How it compares

The Encore GX competes in a crowded segment of small SUVs. The Mazda CX-3, another stylish contender, achieves a slightly lower 29 MPG combined. The Honda HR-V, focusing on practicality, matches the GX at 31 MPG combined. The Nissan Kicks, a value leader, edges ahead with a respectable 33 MPG combined. The Encore GX differs because of its elevated interior trim levels, and the availability of driver-assistance tech, which helps justify its slightly lower fuel economy than the Kicks. Choosing between these cars comes down to priorities.

If fuel economy is your sole consideration, look elsewhere. But if passenger comfort, amenities, and good-but-not-best fuel economy are the goal, the Encore GX earns a spot on your list.

Tips to maximize efficiency

Gentle acceleration is important. The 1.3L 3-cylinder engine doesn’t reward aggressive throttle inputs. Smoothly accelerating from a stop, and anticipating traffic flow, will keep the engine operating in its most efficient zone, maximizing fuel economy. The CVT will also engage the engine, increasing efficiency as the GX accelerates.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and ensure it aligns with the manufacturer’s recommendations found on the door placard.

Reduce excessive idling time. Idling consumes fuel without covering any distance. If you anticipate being stationary for longer than a minute or two, switch off the engine. Restarting is more efficient than prolonged idling, especially with modern engine technology.

Minimize aerodynamic drag. Remove unnecessary items from the roof rack because they disrupt airflow and increase drag, especially at highway speeds. Empty the cargo area of non-essential cargo, as added weight also contributes to lower fuel economy. A clean roof rack and lighter load will make a difference.

Use cruise control strategically. On long stretches of highway, cruise control helps maintain a consistent speed, minimizing fluctuations and maximizing fuel efficiency. However, avoid using cruise control in hilly terrain, where the transmission may downshift frequently, negating any potential fuel savings.
