For owners and prospective buyers of the 2017 Buick Enclave, understanding the vehicle's fuel efficiency is a primary concern for managing long-term ownership costs. The 2017 model year represented a significant moment for the Enclave, as it was the final year for the first-generation Lambda platform before a complete redesign for 2018. During this period, the Enclave offered a blend of comfort, capability, and moderate fuel economy that positioned it competitively in the three-row SUV market. This analysis delves into the specific MPG figures, driving conditions, and factors that influenced the vehicle's real-world fuel consumption.
2017 Buick Enclave MPG Overview
The United States Environmental Protection Agency (EPA) provided standardized ratings that serve as the benchmark for the 2017 Enclave's fuel efficiency. These ratings are calculated through a series of controlled tests designed to simulate city and highway driving. It is important to note that these figures represent an idealized baseline, and actual results can vary significantly based on driving style, load, and environmental conditions. The following breakdown outlines the official EPA estimates for the base models equipped with the standard 3.6-liter V6 engine.
City and Highway Fuel Economy
The EPA testing cycle provided specific data points that help drivers understand the vehicle's efficiency in different scenarios. For the 2017 Buick Enclave with the AWD configuration, the ratings were as follows:
As the data indicates, the all-wheel-drive system, while providing superior traction in adverse weather, comes with a slight penalty in fuel economy compared to the front-wheel-drive variant. The difference is modest but noticeable over the life of the vehicle, particularly for those living in regions with consistent snow or rain.
Factors Influencing Real-World Fuel Efficiency
While the EPA ratings offer a reliable standard, the actual mileage achieved by drivers in 2017 models often tells a different story. The 3.6-liter Pentastar V6 engine, rated at 310 horsepower, provides ample power for highway merging and overtaking, but this performance-oriented tuning requires more fuel during aggressive acceleration. Drivers who adopt a more relaxed driving style, utilizing the available torque smoothly, can often achieve numbers closer to the highway rating.
Furthermore, the Enclave's substantial weight, a characteristic of American full-size SUVs, plays a significant role in fuel consumption. Carrying a full load of passengers and cargo increases the rolling resistance and requires more energy to move the vehicle. Tire pressure is another frequently overlooked variable; under-inflated tires create more rolling resistance, effectively reducing the MPG and costing money at the pump over time.
Fuel Tank Capacity and Driving Range
Practicality is a major selling point for the three-row Enclave, and this is directly tied to its fuel tank capacity. The 2017 model came equipped with a robust 21-gallon fuel tank. By multiplying the combined MPG by the tank capacity, one can estimate the real-world driving range. For a driver achieving the EPA combined rating of 20 MPG, this translates to approximately 420 miles between fill-ups.
