19 MPG combined isn’t going to win any awards, but the 2016 Toyota Sienna AWD 3.5L V6 isn’t trying to compete in a fuel economy race. This Sienna exists to haul families, and their gear, across state lines in comfort and, perhaps more importantly, with unwavering reliability. Fuel efficiency is a consideration, certainly, but it’s rarely the *primary* driver for someone needing three rows and available all-wheel drive. These are buyers who value dependability and space above all else, often with children still in car seats and hockey bags filling the cargo area. They accept the fuel consumption as a consequence of the Sienna’s spaciousness and capability.

City and highway performance

Around town, the Sienna AWD with the 3.5L V6 is rated at 16 MPG. Stop-and-go traffic and frequent short trips will keep you closer to that lower number. The engine’s responsive nature and the transmission’s eagerness to downshift contribute to a feeling of ample power when accelerating from a standstill or merging into traffic. On the open road, the Sienna fares better, achieving a respectable 23 MPG on the highway. Long distances at consistent speeds allow the engine to operate more efficiently, minimizing fuel consumption. While 23 MPG isn’t class-leading, it’s adequate for long road trips, and the Sienna’s comfortable seats and smooth ride help make those journeys more pleasant.

Annual fuel cost

The EPA estimates that the 2016 Toyota Sienna AWD 3.5L V6 will cost $2,300 per year in fuel. This figure is based on driving 15,000 miles annually, with a mix of city and highway driving, and assumes national average fuel prices. Your actual fuel costs may vary depending on your individual driving habits, the type of roads you typically drive on, and local fuel prices. If you primarily drive in stop-and-go city traffic, you’ll likely spend more than $2,300. Conversely, if you spend most of your time on the highway, you might spend less. Understanding how the EPA calculates this figure allows you to adjust your expectations based on your specific circumstances.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy often differs. Factors like driving style, tire pressure, vehicle maintenance, and the use of accessories, like air conditioning, can all impact your MPG. Owners of the 2016 Sienna AWD often report seeing actual MPG figures that are slightly lower than the EPA estimates, particularly in mixed driving conditions. Aggressive acceleration and frequent braking will significantly reduce fuel economy, as will carrying heavy loads or towing. Remember that cold weather can also negatively affect fuel consumption. Keep an eye on your Sienna’s onboard trip computer to track your fuel economy and identify any patterns that might be impacting your MPG.

How it compares

The 2016 Honda Odyssey, a perennial minivan rival, boasts a slightly better EPA-estimated combined fuel economy of 22 MPG in its front-wheel-drive configuration, largely due to its cylinder deactivation technology. The Chrysler Pacifica, new to the scene in model year 2017 (but sometimes shopped against 2016 Siennas), achieves a comparable 22 MPG combined in its standard gasoline form, and the Kia Sedona, another competitor, mirrors the Sienna’s 19 MPG combined. The key differentiator for the Sienna is its available all-wheel drive, a feature neither the Odyssey nor the Pacifica offer, and this is why buyers tolerate the “penalty” at the pump. All Toyota fuel economy data is available for further comparisons. Those wanting better MPGs can see our data on SIENNA MPG across all years for all drivetrains. The extra traction and stability in inclement weather are invaluable for families living in snow-prone areas, thus the Sienna’s lower fuel economy becomes an acceptable tradeoff.

Tips to maximize efficiency

Avoid aggressive acceleration and braking; a smoother driving style can significantly improve fuel economy. The Sienna’s 3.5L V6 provides plenty of power, so there’s no need to constantly floor the accelerator. Anticipate traffic flow and maintain a steady speed whenever possible.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. A small investment in a good tire pressure gauge can pay off in fuel savings.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute, consider turning off the engine. The Sienna’s starter motor is strong and designed to handle frequent starts.

Reduce weight and improve aerodynamics. Remove any unnecessary items from the vehicle to reduce weight, and consider removing any roof racks or cargo carriers that are not in use. These accessories can increase aerodynamic drag, which reduces fuel economy, especially at highway speeds.
