The Buick Envision has a nominal fuel tank capacity of 65 liters. With good vehicle condition, a full tank can cover at least 550 kilometers. The fuel consumption displayed in the onboard computer is a calculated result based on various road conditions through formulas, so it serves only as a long-term reference value and isn't particularly accurate. Fuel consumption is significantly influenced by driving habits, the average speed of the vehicle, and road conditions. Points to note: Different driving habits, varying road conditions, traffic congestion, load weight, fuel quality, use of air conditioning/heating, and whether the car is in the break-in period or an older model can all affect fuel consumption. Generally, the comprehensive fuel consumption ranges around 8-10 liters per 100 kilometers.

I've been driving the Enclave for almost three years, and I feel like a full tank can last between 650 to 850 kilometers, depending on how you drive. During daily commutes stuck in city traffic, the fuel consumption is a bit higher, around 8.5 to 9 liters per 100 kilometers. With a roughly 66-liter fuel tank, it can barely last 750 kilometers. But it's a different story on the highway for long trips—driving at a steady speed with the AC on, the fuel consumption drops to about 7 liters, and the fuel gauge goes down much slower, easily exceeding 800 kilometers. I personally avoid sudden acceleration and hard braking, and I use the eco mode—this car performs quite well. For maintenance, regular oil changes and tire rotations help save fuel; otherwise, carbon buildup can lead to faster fuel consumption. Running the AC in summer does consume more fuel, but overall, it’s no problem for a weekend getaway.

The Envision's range is significantly affected by the model. For example, the 1.5T engine is more fuel-efficient than the 2.0T, with official fuel consumption ranging from 7.2 to 8.8 liters per 100 kilometers, and a fuel tank capacity of 65 to 70 liters. Mathematically, it can ideally run up to 920 kilometers, but in reality, due to traffic congestion or mountainous roads, the range is often between 600 to 780 kilometers. Aggressive driving styles, such as heavy acceleration, can increase fuel consumption by over 1 liter. Air conditioning and heavy loads also add to the burden, increasing fuel consumption by about 10% when fully loaded with luggage or passengers. To save fuel, maintain a steady speed of 60 to 90 km/h and ensure proper tire pressure. In stop-and-go city driving, I've experienced ranges just over 600 kilometers, but planning routes better can improve this. Higher-quality fuel also reduces engine noise, indirectly improving efficiency.

The Envision can typically cover 650 to 800 kilometers on a full tank of gas. It consumes more fuel in the city but is more economical on highways. Avoid speeding or sudden braking, as driving smoothly can reduce fuel consumption by about half a liter. With a full 66-liter tank, a simple calculation shows you can travel 825 kilometers at an average fuel consumption of 8 liters. Running the air conditioning for too long increases fuel usage, especially in summer, so using the recirculation mode can help save some fuel. Personally, I reset the odometer before refueling to track actual data, which helps in better predicting when to refuel. Check tire wear and perform regular maintenance to avoid unnecessary energy consumption. For short commutes, covering 500 kilometers a week is no problem, and for long trips, just plan your gas stops accordingly.
