The 2018 Volkswagen Passat, when equipped with the 3.6L V6 engine, achieves 22 MPG combined. This model isn’t focused on fuel conservation. The Passat V6 is geared toward buyers who prioritize strong power and confident highway passing. It’s a car for those who value a comfortable and spacious cabin, a composed ride, and the readily available power of a naturally aspirated six-cylinder engine, even if it means using more fuel.

City and highway performance

The EPA estimates this Passat configuration at 19 MPG in the city and 28 MPG on the highway. The city figure reflects the energy needed to repeatedly accelerate the relatively heavy sedan from a standstill, something the V6 handles easily. The highway number is more respectable. With the six-speed automatic transmission in its highest gear, the V6 works easily, providing decent mileage for long road trips. These numbers may not be record-setting, but they are reasonable for a vehicle of this size and performance level.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Volkswagen Passat 3.6L at $2,000. This is based on driving 15,000 miles per year and using fuel prices at the time of the EPA’s testing. This is a national average, so your actual fuel costs will vary depending on your driving habits, the type of driving you do, and the price of gasoline in your area. Stop-and-go driving will significantly increase your fuel bill, while consistent highway cruising could lower it. It’s a useful benchmark.

Real-world expectations

EPA numbers are a guide, but real-world mileage can differ. Drivers who frequently accelerate quickly or spend most of their time in heavy traffic will likely see figures below the official estimates. Conversely, those who drive smoothly and stick to highway cruising may find themselves exceeding the 28 MPG highway rating. The Passat’s trip computer can offer a more accurate picture of your individual fuel consumption, factoring in your specific driving style and conditions daily.

How it compares

The 2018 Passat V6’s fuel economy is lower than some of its four-cylinder rivals in the mid-size sedan segment. The Honda Accord 1.5T, for example, achieves 30 MPG combined, while the Toyota Camry 2.5L manages around 32 MPG. Even the V6 in the Camry has better MPG than the Passat, with the Camry V6 rated at 26 MPG combined. The difference matters to some buyers prioritizing fuel efficiency. The Passat V6’s target demographic often accepts this trade-off for the added performance and smoothness that a six-cylinder engine provides.

Tips to maximize efficiency

The Passat’s six-speed automatic transmission is responsive. Avoid aggressive acceleration from a standstill; building speed gradually allows the engine to operate more efficiently, minimizing fuel consumption during the most demanding driving phase.

Maintain a steady speed on the highway to reduce the need for acceleration and deceleration. The result will be improved fuel efficiency. Cruise control can help you maintain a consistent speed and optimize fuel consumption on relatively flat terrain.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly and inflate them to the levels listed on the doorjamb.

Consistent oil changes, air filter replacements, and spark plug maintenance contribute to optimal engine performance and fuel efficiency. A well-maintained engine runs cleaner and more efficiently than one that is neglected.

Reducing unnecessary weight in the vehicle can increase fuel economy. Removing unnecessary items from the trunk and cabin to lighten the load improves efficiency, saving you money.
