24 MPG combined is an adequate figure for the 2015 Toyota Avalon with the 3.5L V6, but fuel economy isn’t usually the main purchase reason. This car is designed for quiet comfort over long distances, and the V6 provides smooth, effortless power that helps achieve that goal. The buyer who chooses the V6 Avalon likely values refinement and readily available power over maximizing every last mile per gallon.

City and highway performance

The EPA estimates for the 2015 Avalon 3.5L V6 are 21 MPG in the city and 30 MPG on the highway. The city figure reflects the Avalon’s weight and the inherent inefficiencies of stop-and-go driving, but it’s still respectable for a car of this size with a naturally aspirated V6. The 30 MPG highway figure is more impressive and shows the engine’s ability to cruise comfortably at higher speeds without using excessive fuel. The six-speed automatic transmission also helps, optimizing gear ratios for both acceleration and efficiency.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Toyota Avalon 3.5L V6 is $1,800. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel cost will vary depending on your driving habits and the price of gasoline in your area. If you primarily drive in the city or have a lead foot, you can expect to spend more than $1,800 per year. If you do a lot of highway driving and practice fuel-efficient driving techniques, you may be able to beat that figure. See all Toyota fuel economy data for more information.

Real-world expectations

While the EPA estimates provide a useful baseline, your real-world fuel economy may differ. Many owners report figures close to the EPA estimates, especially on the highway. Expect a dip in MPG with frequent hard acceleration or if the car is mostly used for short trips. The Avalon’s trip computer can provide a running average of your fuel economy, giving you a better understanding of your consumption.

How it compares

When comparing the 2015 Avalon V6 to its competitors, the fuel economy picture becomes clearer. The Nissan Maxima, also equipped with a 3.5L V6, achieves similar figures, around 22 MPG combined. The Chrysler 300S with the 3.6L V6 is in the same ballpark, though its optional all-wheel drive will reduce fuel economy slightly. The Avalon stands out when compared to models that value fuel efficiency over outright power. The Avalon Hybrid offers significantly better fuel economy (around 40 MPG combined), at the cost of some performance and a slightly higher purchase price. Another example is the Buick LaCrosse with its available eAssist mild-hybrid system, which delivers slightly better MPG but doesn’t offer the same level of smooth V6 power. For some buyers, the Avalon’s balance of power and reasonable efficiency is a good compromise. See AVALON MPG across all years for more information.

Tips to maximize efficiency

Maintaining proper tire inflation is critical for optimizing fuel economy. Check your tires regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel.

Avoid aggressive acceleration and braking. The Avalon’s V6 offers plenty of power, but using it carefully will significantly improve your MPG. Gentle acceleration and smooth braking not only conserve fuel but also contribute to a more comfortable ride.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk or back seat adds weight, which reduces fuel economy. Remove items that you don’t need to carry regularly.

Minimize idling. Idling consumes fuel without moving the vehicle. If you expect to be stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. The Avalon’s smooth and quiet starting system makes this a convenient option.

Consider using cruise control on the highway. Cruise control helps maintain a constant speed, which can improve fuel economy on long trips. Avoid using cruise control in hilly terrain, as the vehicle may downshift frequently, potentially reducing any gains.
