A combined fuel economy of 26 MPG firmly positions the 2020 Toyota Avalon XLE with its 3.5L V6 as a comfortable, spacious, and reasonably efficient full-size sedan. This isn’t a hybrid chasing ultimate efficiency, nor is it a sports sedan prioritizing performance above all else. Instead, it’s a meticulously engineered machine designed for quiet, reliable transportation; a choice that trades outright fuel savings for smooth power delivery and a refined driving experience. This trade-off is perfectly acceptable to the Avalon’s target buyer: someone who prioritizes comfort, space, and reliability over squeezing every last mile from a gallon of gasoline.

City and highway performance

The EPA estimates the 2020 Avalon XLE will achieve 22 MPG in the city and 32 MPG on the highway. The city figure is where the Avalon’s size and naturally aspirated V6 can become apparent. Stop-and-go traffic will inevitably dip into that 22 MPG figure, and the absence of electric assistance means the engine is always working. On the open road, however, the Avalon shines.

The 32 MPG highway rating is easily achievable, thanks in part to the smooth-shifting 8-speed automatic transmission that allows the engine to cruise comfortably at lower RPMs. This makes it a genuinely comfortable and relatively efficient long-distance cruiser.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Toyota Avalon XLE is precisely $1,700. This figure is calculated based on driving 15,000 miles per year, using the then-current national average fuel price. It’s a useful, standardized number for comparison shopping, but individuals’ actual fuel costs will vary based on driving habits, location, and fluctuating gas prices. Don’t consider it a guaranteed expense; treat it as a benchmark.

Real-world expectations

While the EPA ratings provide a standardized benchmark, real-world fuel economy always depends on individual driving style and conditions. Aggressive acceleration, frequent hard braking, and continuous short trips will all negatively impact fuel consumption. In contrast, those who prioritize smooth, consistent driving and spend more time on the highway will likely see figures closer to, or even slightly exceeding, the EPA estimates. The V6 engine, while powerful, is also relatively responsive to gentle inputs from the driver, rewarding a more economical approach.

How it compares

In the realm of large sedans, the Avalon’s fuel economy is competitive, if not class-leading. The Nissan Maxima, with its 3.5L V6, also achieves a similar 24 MPG combined, offering comparable performance and efficiency. The Chrysler 300, depending on the engine configuration, can range from a less efficient 19 MPG combined with the V8 to a more competitive 23 MPG with the V6.

Hybrid versions of similar-sized sedans, like the Toyota Camry Hybrid (offering upwards of 52 MPG combined), deliver significantly better fuel economy, but at the expense of a somewhat different driving experience. For drivers prioritizing a traditional V6 engine’s smooth power delivery in a full-size sedan, the Avalon strikes a reasonable balance.

Tips to maximize efficiency

Anticipate traffic flow and maintain a steady speed whenever possible. The Avalon’s engine is most efficient at a consistent pace, particularly on the highway. Avoid sudden acceleration and hard braking, as these actions burn extra fuel unnecessarily, especially in a larger sedan like the Avalon.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and ultimately reducing fuel economy. Check your tire pressure regularly, especially during temperature changes.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk adds to the vehicle’s overall weight, decreasing fuel efficiency. Remove any items you don’t need to improve your MPG.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, minimizing speed fluctuations and optimizing fuel consumption. This is especially helpful on relatively flat stretches of highway.

Keep up with scheduled maintenance, including oil changes and air filter replacements. A well-maintained engine runs more efficiently, maximizing fuel economy. Following the manufacturer’s recommended maintenance schedule is critical for long-term reliability and optimal fuel performance.
