24 MPG combined might not sound earth-shattering, but for the 2017 Buick Envision AWD with the 2.5L 4-cylinder engine, it’s a pragmatic compromise between capability, comfort, and acceptable running costs. This isn’t a Prius competitor, nor is it trying to be. The Envision, in this configuration, aims squarely at buyers who need a comfortable, well-equipped crossover with all-wheel drive for challenging weather, but aren’t willing to pay a premium for a more efficient hybrid or deal with the compromises of a smaller, less refined vehicle.

City and highway performance

The EPA estimates of 21 MPG in the city and 28 MPG on the highway paint a more nuanced picture of where the Envision’s fuel economy excels. The city figure reflects the added weight and friction of stop-and-go driving, where the naturally aspirated 2.5L engine needs to work harder to get the Envision moving. The 6-speed automatic transmission, while smooth, isn’t the most cutting-edge in terms of fuel-saving technology. However, the 28 MPG highway figure suggests that on longer trips, where the engine can settle into a more efficient cruising speed and the all-wheel-drive system is less engaged, the Envision is surprisingly respectable. These figures would appeal to someone who commutes primarily in the suburbs, or takes regular highway trips.

Annual Fuel Cost

The EPA estimates that the annual fuel cost for the 2017 Buick Envision AWD 2.5L 4-cyl is $1,800. 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. It also assumes national average fuel prices for regular unleaded gasoline. This $1,800 figure gives potential buyers a clear benchmark to compare running costs against other vehicles in the segment. Remember that this is an estimate. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and vehicle maintenance.

Real-World Expectations

While the EPA provides a standardized testing procedure, real-world driving often deviates from these ideal conditions. Expect to see figures that fluctuate around the EPA estimates, leaning lower during periods of heavy city driving or aggressive acceleration. Conversely, a long road trip at a consistent speed might yield fuel economy slightly exceeding the 28 MPG highway rating. Factors like tire pressure, vehicle load, and even the use of accessories like air conditioning can influence your actual MPG. Owners who prioritize fuel economy should practice smooth acceleration, avoid excessive idling, and ensure their vehicle is properly maintained.

How it compares

The 2017 Buick Envision exists in a competitive landscape. The Acura RDX, for example, typically achieves around 20 MPG city and 28 MPG highway. While the highway number is similar, the RDX, often equipped with a more powerful engine, may appeal to drivers who prioritize performance. The Lexus NX 300h hybrid easily surpasses the Envision with an EPA-estimated 33 MPG combined. However, the NX 300h commands a higher price and some buyers might prefer the more traditional driving experience of the Envision. Even the Honda CR-V achieves around 28 MPG combined with its turbo engine, making it a more efficient choice. The Envision’s 24 MPG simply emphasizes its primary focus: offering Buick-style comfort and available AWD at a price point that doesn’t break the bank. See ENVISION MPG across all years.

Tips to maximize efficiency

The 2.5L engine in the 2017 Envision isn’t inherently inefficient, but its older design means it relies more on driving habits to achieve optimal numbers. Avoid aggressive acceleration and braking, as these actions consume a significant amount of fuel. Anticipate traffic conditions and maintain a steady speed whenever possible to reduce unnecessary fuel consumption.

Regular maintenance is key. Make sure your tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce fuel economy. And ensure your engine air filter is clean, as a dirty filter restricts airflow and forces the engine to work harder.

Minimize idling. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t be causing undue wear or using excessive fuel restarting.

Consider your cargo. Extra weight in the vehicle reduces fuel efficiency. Remove any unnecessary items from the trunk or cargo area, and avoid carrying heavy loads unless absolutely necessary.
