The 2015 Volkswagen Passat 1.8L, with its smooth six-speed automatic, gets 28 MPG combined. That’s a solid balance between fuel efficiency and the spacious interior families and commuters want. It’s not trying to get hybrid-level MPG, but instead provides dependable gas mileage in a car known for its comfortable ride and generous rear-seat legroom, qualities that its buyers value.

City and highway performance

The EPA estimates the 2015 Passat 1.8L at 24 MPG in the city and a more impressive 35 MPG on the highway. The highway number is particularly important for the Passat, because many buyers drive a lot of miles on long commutes or family road trips. The 1.8L turbocharged engine provides enough power for merging and passing, even when the car is full of passengers and luggage, without sacrificing fuel efficiency on those long highway drives. The city MPG, while lower, is still reasonable for a car of this size and capability. It reflects the engine’s responsiveness and the transmission’s smooth shifts in stop-and-go traffic.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Volkswagen Passat 1.8L is $1,550. This is based on driving 15,000 miles per year and using national average fuel prices, and it’s a useful way to compare the Passat’s running costs with other cars in its class. Remember that actual fuel costs can change a lot, depending on how you drive, local gas prices, and the type of fuel you use. Even so, the $1,550 gives you an estimate to help budget and understand the overall cost of ownership before you check out PASSAT MPG across all years.

Real-world expectations

EPA estimates are a useful starting point, but real-world fuel economy can change based on driving style, traffic, and even tire pressure. Passat drivers who accelerate smoothly, anticipate traffic, and maintain their cars well are more likely to get MPG that’s close to the EPA’s estimates. On the other hand, aggressive driving, frequent short trips, and skipping maintenance can hurt fuel economy. The Passat’s comfortable ride and responsive engine can sometimes encourage drivers to accelerate more, so driving efficiently is important to save gas.

How it compares

The 2015 Passat 1.8L is in a competitive class of mid-size sedans, and they all have different fuel efficiency strengths and weaknesses. For example, the 2015 Honda Accord LX with its 2.4L engine gets an EPA-rated 31 MPG combined, which is slightly better than the Passat. The 2015 Toyota Camry LE, another popular car, gets a similar 28 MPG combined. However, the Passat often appeals to buyers who want a more refined driving experience and more interior space than the Camry provides. The Mazda6 i Grand Touring, known for its sporty handling, gets a respectable 32 MPG combined. Buyers who want more interior space and a comfortable ride might still choose the Passat, even with a slightly lower MPG rating. Before deciding, it’s important to compare all Volkswagen fuel economy data with competing brands.

Tips to maximize efficiency

Proper tire inflation is critical to getting the best gas mileage in your 2015 Passat. Check your tire pressure often, and inflate the tires to the pressure on the doorjamb sticker. Do not inflate them to the maximum pressure on the tire itself. Even a few PSI below the recommended pressure can increase rolling resistance and lower fuel efficiency.

Avoid idling too long, especially in the winter. The 1.8L turbo engine warms up pretty quickly, so you don’t need to let it idle for a long time before driving. If you’re going to be stopped for more than a minute, turning off the engine is usually better for fuel economy than idling.

Use cruise control on the highway to keep a consistent speed and avoid accelerating and decelerating unnecessarily. The Passat’s cruise control system is responsive and works well. It helps you keep a steady pace and save gas on long drives. Avoid speeding, because fuel economy drops quickly at higher speeds.

Make sure your Passat gets regular maintenance, including oil changes, air filter replacements, and spark plug replacements, as the manufacturer recommends. A well-maintained engine runs more efficiently and burns fuel cleaner. Neglecting maintenance can decrease performance and reduce fuel economy.

Consider fuel additives that clean fuel injectors and improve combustion. While they don’t replace regular maintenance, these additives can help your fuel system run smoothly and might slightly improve gas mileage. Look for additives made for turbocharged gasoline engines.
