The 2021 Volkswagen Passat 2.0L 4-cyl achieves 28 MPG combined, offering respectable fuel economy, though this isn’t the main reason to buy this mid-size sedan. People buy this car for its comfortable ride, large back seat, and ample trunk space, qualities valued by families and those who frequently transport passengers. Fuel economy is less important than these practical factors, but it’s a welcome reassurance that you’re not burning through fuel unnecessarily.

City and highway performance

The Passat’s EPA estimates are 24 MPG in the city and 36 MPG on the highway. These figures are due to its 2.0-liter turbocharged four-cylinder engine and six-speed automatic transmission. The city MPG is good enough for stop-and-go driving, where the Passat’s smooth power delivery helps it pull away from lights without using too much throttle. On the highway, the 36 MPG rating makes the Passat a good long-distance cruiser. The six-speed automatic, while not as advanced as some of the eight- or ten-speed units in competitors, does its job efficiently, keeping the engine at its best for highway passing while also delivering good fuel economy at cruising speed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Volkswagen Passat at $1,550. This is based on driving 15,000 miles per year and using national average fuel prices. This figure gives potential owners a clear idea, allowing them to consider fuel costs in their overall budget. Remember that real-world fuel costs will vary depending on driving habits, location, and changes in fuel prices. This $1,550 figure shows how well designed the Passat is for reasonable fuel consumption.

Real-world expectations

While the EPA provides standardized testing data, your personal driving habits will greatly change your real-world fuel economy. Driving aggressively, braking hard often, and speeding will all decrease your MPG. On the other hand, driving smoothly and predictably, and obeying speed limits will help you achieve or even exceed the EPA estimates. The Passat’s relatively light weight for its class also helps in real-world efficiency, as it doesn’t need as much energy to get moving as some larger or heavier sedans. Stop-and-go traffic will always lower fuel economy more than free-flowing highway miles.

How it compares

The Passat’s fuel economy is competitive in the mid-size sedan segment, but not the best. For example, the Toyota Camry LE with its 2.5-liter four-cylinder achieves 28 MPG combined (28 city/39 highway), which offers slightly better highway fuel economy. The Honda Accord LX with its 1.5-liter turbocharged engine gets 33 MPG combined (30 city/38 highway), giving more efficient performance in both city and highway driving. However, many buyers choose the Passat for its larger interior and more traditional sedan styling, taking a slight reduction in fuel economy for these other benefits. The Nissan Altima S, rated at 32 MPG combined (28 city/39 highway), also provides an option for those who want better fuel efficiency. Before buying, consider reviewing all Volkswagen fuel economy data. Finally, take some time to review the PASSAT MPG across all years.

Tips to maximize efficiency

Keeping your tires properly inflated is important for getting the best fuel economy. Check your tire pressure often and make sure it’s at the recommended level, which is usually on a sticker inside the driver’s side doorjamb. Tires that don’t have enough air increase rolling resistance, making the engine work harder and use more fuel.

Avoid idling if you don’t need to. If you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. Modern engine starting systems are made to handle frequent starts and stops, and the fuel saved by not idling can add up over time, especially during city driving.

Use cruise control on the highway when you can. Keeping a consistent speed helps the engine operate more efficiently. Avoid accelerating and decelerating quickly, as these actions waste fuel. Gentle, gradual changes in speed are always the best way to get the most MPG.

Regular maintenance, including oil changes and air filter replacements, is important. A clean air filter makes sure the engine gets enough air, while fresh oil reduces friction and lets the engine run more smoothly. Following the manufacturer’s recommended maintenance schedule is the best way to keep your Passat running efficiently.
