While 19 MPG combined isn’t stellar, fuel efficiency isn’t the core purpose of the 2015 BMW 750Li xDrive. It’s a luxury flagship sedan, suggesting success, and a mobile center for executives prioritizing comfort, performance, and all-weather capability. Efficiency is secondary, even if desired.

City and highway performance

The EPA estimates the 2015 BMW 750Li xDrive at 16 MPG city and 24 MPG highway. The city figure reflects hauling a heavy, technology-laden sedan through stop-and-go traffic with a powerful V8. The highway number is more acceptable, as the 8-speed automatic transmission settles into a relaxed gear, allowing the engine to cruise. Even on the open road, using the engine’s strong power can easily drop mileage below the EPA estimate. This engine requires premium gasoline. If you don’t use premium fuel, the engine control unit will reduce the engine’s timing and power to protect it, and you’ll lose fuel economy and performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 BMW 750Li xDrive at $3,050. This is based on driving 15,000 miles per year and using national average fuel prices during EPA testing. Fuel prices fluctuate, and personal driving habits greatly impact fuel costs. Short city trips will likely exceed this estimate, while mostly highway driving could be lower.

Real-world expectations

Don’t expect to consistently match the EPA numbers, if you drive aggressively. The 750Li xDrive delivers effortless acceleration and a comfortable ride, making it easy to accelerate. Factors like traffic, weather, and tire pressure also influence fuel economy. If fuel economy is a primary concern, explore all Bmw fuel economy data to find alternatives. Those who want more detailed data should consider the 750LI MPG across all years to pinpoint their ideal balance of efficiency and features.

How it compares

The 2015 BMW 750Li xDrive’s competitors offer differing fuel economy. The Mercedes-Benz S550 4Matic gets about the same at 16 MPG city and 26 MPG highway using a similar turbocharged V8. The Audi A8 4.0T quattro offers similar performance, coming in around 18 MPG city and 29 MPG highway. These differences are unlikely to sway a buyer. The decision often comes down to brand preference, features, and overall driving experience rather than a few miles per gallon. Selecting the right tires can also alter that fuel economy.

Tips to maximize efficiency

Use the BMW’s driving mode selector. “Eco Pro” mode can improve fuel economy by optimizing throttle response, gearshifts, and climate control settings. Pay attention to the “EfficientDynamics” display in the instrument cluster, which provides feedback on your driving habits and offers suggestions. This helps develop a lighter touch on the accelerator.

Ensure your tires are inflated to the recommended pressure, found on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel economy. It’s a simple maintenance task that can make a difference. Remember that weather can impact your tire pressure, so check them regularly.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Modern engines restart quickly, and idling consumes fuel without benefit. Avoiding idling can save fuel, especially in urban environments.

Consider using cruise control on long highway trips. Maintaining consistent speed helps optimize fuel economy. Be mindful of hills and traffic and adjust your speed. Cruise control works best on flat and open roads with little traffic.

Schedule regular maintenance, including oil changes and air filter replacements. A well-maintained engine runs efficiently. A dirty air filter restricts airflow, which can reduce fuel economy. Following the manufacturer’s schedule will ensure the 750Li xDrive is operating at its best.
