20 MPG combined. That’s the figure for the 2016 BMW 550i with its 4.4L V8, and it requires context. This isn’t a Prius competitor; it’s a performance-oriented luxury sedan designed for effortless power and a connected driving experience. The MPG is about the price one pays for a specific type of thrill, rather than hypermiling. The 550i buyer wants rapid acceleration, a refined engine note, and the prestige of the BMW badge. Fuel economy is a secondary consideration, acknowledged but not prioritized above the driving experience.

City and highway performance

The EPA estimates the 2016 BMW 550i at 17 MPG in the city and 25 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the engine spends more time idling or accelerating from a standstill, actions that dramatically reduce fuel efficiency. The 25 MPG highway estimate is more aligned with the vehicle’s ability to cruise. On long road trips, with consistent speeds and minimal braking, the 550i can achieve fuel consumption closer to this rating, particularly if the driver employs a gentle right foot. However, the temptation to tap the V8’s power is always there, and frequent bursts of acceleration will quickly reduce those highway gains.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW 550i at $2,900. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices at the time of the estimate. It’s important to recognize that this $2,900 figure is an average. Individual fuel costs will vary depending on driving habits, local fuel prices, and the specific ratio of city to highway driving. Someone who primarily drives in congested city environments will likely exceed this estimate, while someone who frequently embarks on long highway trips may see lower fuel expenses.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world fuel economy often deviates. 2016 BMW 550i owners often report figures slightly below the EPA’s combined estimate, especially in mixed driving conditions. Spirited driving, a heavy foot on the accelerator, and frequent use of the Sport driving mode will all negatively impact fuel consumption. Conversely, using Eco Pro mode and practicing smooth, anticipatory driving can nudge the figures closer to the EPA’s estimates. Ultimately, the actual MPG achieved depends greatly on the driver’s behavior and the driving conditions. You can see 550I MPG across all years to find better or worse years for MPG.

How it compares

Compared to its competitors, the 2016 BMW 550i’s fuel economy is typical for a V8-powered luxury sedan. The Mercedes-Benz E550 of the same year, also featuring a twin-turbo V8, achieves similar EPA ratings, around 17 city and 25 highway. Audi’s S6, with its turbocharged V8, offers comparable figures as well. These cars appeal to a similar buyer; someone who values performance and luxury over outright fuel efficiency; however, stepping down to a six-cylinder engine from BMW itself, such as the 535i with its turbocharged inline-six, boosts fuel economy significantly, potentially reaching around 23 MPG combined, a meaningful improvement. A buyer cross-shopping these models must weigh the trade-off between V8 power and better fuel efficiency. If fuel economy is a greater concern there is still all Bmw fuel economy data available, even hybrid models.

Tips to maximize efficiency

Use Eco Pro mode. This setting recalibrates the engine and transmission for maximum efficiency, often dulling throttle response and shifting at lower RPMs. While it might diminish the car’s performance, it can noticeably improve fuel economy, especially in city driving. It encourages a more relaxed driving style.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressures regularly and inflate them to the recommended levels found on the sticker inside the driver’s side door jamb.

Anticipate traffic flow. Aggressive acceleration and braking consume excessive fuel. By anticipating traffic patterns and maintaining a consistent speed, you can minimize unnecessary acceleration and deceleration, improving your overall MPG. This driving style is key to improving fuel economy across all vehicles, but is especially true of gasoline engines.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute or two, turn off the engine. Modern vehicles, including the 2016 550i, restart quickly and efficiently, making this a simple way to save fuel.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, preventing unintended acceleration and deceleration. This is particularly effective on long, flat stretches of highway and can significantly improve fuel economy.
