The 2015 BMW 535i’s 24 MPG combined fuel economy may not be the best, but it’s a respectable number for a mid-size luxury sedan that values a smooth, powerful driving experience and a prestigious image . This car isn’t for those obsessed with fuel efficiency; it’s for drivers who appreciate a finely engineered inline-six engine and BMW’s well-known driving dynamics. They’re willing to trade some fuel efficiency for the refined performance and status the 535i offers.

City and highway performance

The EPA estimates for the 2015 BMW 535i, with its 3.0L inline-six and eight-speed automatic transmission, are 20 MPG in the city and 30 MPG on the highway. The city figure reflects stop-and-go driving where the engine works harder to accelerate the car’s weight. The highway number shows the engine’s efficiency at a constant cruising speed. The eight-speed automatic keeps the engine in its optimal range, balancing power and fuel consumption on the open road. Drivers who spend more time on the highway can expect to get closer to 30 MPG, while those mainly driving in cities will likely see numbers around, or below, 20 MPG. The actual MPG of the 535I MPG across all years depends on driving habits.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 BMW 535i at $2,400. This is based on driving 15,000 miles per year and using the national average fuel price at the time of testing. Remember that this is just an estimate. Your actual fuel costs will change based on how many miles you drive, the type of driving you do (city vs. highway), and the price of gasoline in your area. Aggressive driving, like frequent hard acceleration, can increase your fuel expenditure, pushing your annual cost above $2,400.

Real-world expectations

While the EPA provides a standard, real-world fuel economy often differs.

Many 2015 BMW 535i owners report getting numbers close to the EPA estimates, with some exceeding the highway number on long trips. However, aggressive driving or mostly city driving can lower the average. Factors like tire pressure, vehicle maintenance, and even the type of gasoline can affect fuel efficiency. Drivers who use the “Eco Pro” driving mode, which changes vehicle settings for fuel savings, are more likely to see results closer to the EPA figures.

How it compares

The 2015 BMW 535i’s fuel economy is similar to others in its class. The 2015 Mercedes-Benz E350, with its 3.5L V6, gets about 20 MPG city and 29 MPG highway. The 2015 Audi A6 3.0T, with its supercharged V6, gets 20 MPG city and 30 MPG highway. A 2015 Lexus GS 350 offers 19 MPG city and 29 MPG highway. The 535i’s fuel economy is generally in line with its competitors, and buyers considering these cars are probably prioritizing other things like performance, luxury features, and brand reputation over small MPG differences. Driving mode selection can affect fuel usage, and all Bmw fuel economy data is a good way to compare models.

Tips to maximize efficiency

Take advantage of Eco Pro driving mode. This setting changes the throttle response, transmission shift points, and climate control system to prioritize fuel economy. It’s a simple way to reduce fuel use, especially during commutes or long highway drives.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which makes the engine work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended levels on the sticker inside the driver’s side doorjamb.

Avoid aggressive driving. Rapid acceleration, hard braking, and speeding reduce fuel economy. Drive smoothly and watch traffic to minimize unnecessary acceleration and braking.

Keep up with routine maintenance. Regular oil changes, air filter replacements, and spark plug maintenance keep the engine running efficiently. A well-maintained engine uses less fuel and works at its best.

Reduce unnecessary weight. Extra weight in your car increases fuel use. Remove unnecessary items to lighten the load and improve fuel economy.
