25 MPG combined isn’t going to win any hypermiling contests, but it’s perfectly acceptable for the 2021 Toyota Avalon equipped with the 3.5L V6. This isn’t a car for chasing ultimate efficiency; it’s for comfortably and reliably transporting people and their cargo across hundreds of miles. This specific Avalon appeals to buyers who value a smooth, powerful engine and a spacious cabin, likely prioritizing those qualities over squeezing every last drop of fuel.

City and highway performance

The EPA estimates the Avalon V6 at 22 MPG in the city and 31 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the Avalon’s weight and the engine’s displacement work against it. The highway number is more palatable, because the eight-speed automatic transmission allows the engine to cruise at relatively low RPMs. This spread between city and highway suggests the Avalon V6 is better suited for longer trips than daily commutes.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Toyota Avalon 3.5L V6 is $1,750. This calculation assumes 15,000 miles of driving per year and uses national average fuel prices. Your individual fuel costs will vary based on your driving habits, the type of driving you do, and the price of fuel in your area. However, the $1,750 figure provides a reasonable benchmark for potential owners to understand the ongoing cost of operating this particular Avalon configuration.

Real-world expectations

While the EPA estimates are useful for comparison, real-world fuel economy always varies. Drivers with a lead foot or those who frequently carry passengers and cargo will likely see numbers below the EPA estimates. Conversely, careful drivers who prioritize smooth acceleration and consistent speeds can often match or even slightly exceed the EPA’s figures. Temperature also plays a role; cold weather typically reduces fuel economy, as does using the air conditioning extensively. Ultimately, consistent driving habits have the biggest impact on fuel efficiency.

How it compares

The Avalon’s fuel economy places it squarely in the middle of its competitive set. A similarly equipped Nissan Maxima, known for its sporty driving dynamics, achieves around 24 MPG combined. The V6-powered Chrysler 300, another large sedan competitor, posts figures very close to the Avalon. Even four-cylinder powered rivals, like the Honda Accord 2.0T, achieves around 26 MPG combined, demonstrating that outright cylinder count doesn’t always dictate fuel economy. These slight differences matter less to Avalon buyers, who often prioritize the smooth power delivery and refinement for which the V6 engine is known. You can also compare the AVALON MPG across all years.

Tips to maximize efficiency

Aggressive acceleration consumes significantly more fuel. The Avalon’s V6 offers ample power, encouraging drivers to dip deep into the throttle. However, smooth and gradual acceleration helps to conserve fuel, minimizing the amount of gasoline injected with each press of the accelerator pedal.

Maintaining proper tire inflation is critical for fuel efficiency and vehicle safety. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side door jamb.

While tempting, avoid prolonged idling. Modern engines are designed to operate efficiently when warmed up, and idling for extended periods wastes fuel. If you anticipate stopping for more than a minute, it’s generally more efficient to turn off the engine.

Reduce unnecessary weight. Excess cargo in the trunk or back seat adds weight to the vehicle, which in turn reduces fuel economy. Remove any items you don’t need to carry regularly to improve efficiency. Also, carrying cargo on the roof adds significant aerodynamic drag, negating some of Avalon’s sleek shape.

Consider milder ambient settings for the air conditioning. Avalon drivers often select MAX AC in the summer months to overcome the climate control system’s lag. While this is sometimes unavoidable, consider using lower blower settings and slightly higher temperature settings once the cabin has cooled. This will reduce the load on the engine and improve overall fuel efficiency. Remember to check all Toyota fuel economy data as you shop.
