20 MPG combined is not a number that will excite most people, especially now that there are hybrid SUVs and all-electric sedans. However, this figure probably won’t matter much to anyone considering a 2019 BMW Alpina B6 xDrive Gran Coupe. People don’t buy this car to save money on gas. It’s a statement of taste, a declaration of performance, and an exquisitely crafted machine. The fuel economy is simply what you have to pay to join this exclusive club.

City and highway performance

The Alpina B6’s EPA ratings are 17 MPG in the city and 25 MPG on the highway. The city figure shows what happens when you drive a twin-turbocharged 4.4-liter V8 through stop-and-go traffic. The engine’s power and the car’s weight require fuel. The highway number suggests the B6’s dual nature. With its long gearing from the 8-speed automatic transmission (indicated as “S8” by the EPA) and relatively efficient engine, it can achieve reasonable efficiency when cruising at higher speeds. If you avoid flooring the accelerator, the B6 will reward you with slightly better mileage.

Annual fuel cost

The EPA estimates that it costs $2,900 per year to fuel the 2019 BMW Alpina B6 xDrive Gran Coupe. This is based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel price for premium gasoline. It’s a substantial amount, which reflects the car’s need for high-octane fuel and performance-oriented engineering. However, for the typical B6 owner, this is a predictable expense given the vehicle’s price and the driving experience.

Real-world expectations

Real-world fuel economy often differs from EPA estimates. Several factors will affect the Alpina B6’s results. Aggressive driving will worsen fuel economy, potentially dropping below the EPA’s 17 MPG city rating. Careful highway driving might yield slightly better than the 25 MPG estimate. The car’s age, tire pressure, and even the gasoline grade can subtly impact efficiency. Expect a range between the EPA figures, with your driving style being the biggest factor.

How it compares

Compared to other high-performance luxury sedans, the Alpina B6’s fuel economy is normal. A Mercedes-AMG S63 Sedan, with its own twin-turbo V8, achieves around 17 MPG combined. The Porsche Panamera Turbo offers a slightly better 19 MPG combined, but doesn’t have the B6’s exclusivity and handcrafted feel. Even some performance SUVs like the BMW X5 M perform similarly, achieving around 16 MPG combined. The B6’s primary appeal is the unique blend of blistering performance, luxurious features, and the subtle presence that separates it from other performance vehicles.

Tips to maximize efficiency

While fuel economy might not be important to Alpina B6 owners, there are ways to optimize efficiency without changing the driving experience. Avoid excessive idling. The B6’s engine uses fuel even when stopped. If you will be stopped for more than a minute or two, switch the engine off.

Keep the tires properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and consuming more fuel. Check your tire pressures regularly and inflate to the levels listed on the door jamb.

Gentle acceleration and braking can also help. Avoid stomping on the gas pedal or slamming on the brakes. Smooth inputs will improve fuel economy and enhance the driving experience.

Consider using the car’s Eco Pro driving mode, if equipped. While it might reduce throttle response slightly, it prioritizes fuel efficiency by optimizing engine and transmission settings. Explore current ALPINA MPG across all years to see how different features can affect efficiency.

Regular maintenance is critical. Ensure that your B6 receives scheduled service, including oil changes, filter replacements, and spark plug replacements. A maintained engine runs more efficiently and delivers optimal fuel economy. Responsible driving habits can translate to less gas consumption without reducing the Alpina B6’s performance.
