19 MPG combined isn’t going to win any awards. It’s the price to pay for the 2025 BMW Alpina B8 Gran Coupe, a car that prioritizes handcrafted luxury and serious performance over saving gas. This isn’t a grocery-getter; it’s a statement, a continent-crosser, a bespoke experience for drivers who value exclusivity and unapologetic power.

City and highway performance

The EPA estimates the Alpina B8 Gran Coupe will achieve 17 MPG in city driving and 24 MPG on the highway. The city figure is what you’d expect from a large displacement, twin-turbocharged V8 working through stop-and-go traffic. The highway number is more respectable, hinting at the engine’s ability to deliver effortless cruising when the road opens up. The eight-speed automatic transmission, tuned by Alpina, plays a critical role here, selecting the best gear to balance performance and fuel consumption. Just don’t expect to see those highway numbers very often because the allure of the B8’s prodigious torque is tough to resist.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW Alpina B8 Gran Coupe at $3,050. This calculation is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. It’s a significant sum, reflecting both the B8’s thirst for premium gasoline and the typical driving habits of its owners. These are buyers less concerned with pennies per gallon and more with experiencing the intoxicating surge of 612 horsepower.

Real-world expectations

While the EPA figures provide a useful baseline, real-world MPG for the Alpina B8 Gran Coupe is highly dependent on driving style. A driver who regularly uses the engine’s potential will likely see fuel economy figures below the EPA estimates. Conversely, a driver who prioritizes smooth, consistent acceleration and anticipates traffic flow could potentially achieve numbers closer to, or even slightly above, the EPA figures, especially on long highway journeys. The B8’s character encourages spirited driving, so expect to be closer to the lower end of the spectrum unless consciously making an effort to conserve fuel.

How it compares

The Alpina B8 exists in a niche segment of high-performance luxury four-door coupes, and its fuel economy reflects this. For example, the Mercedes-AMG GT 63 S 4-Door Coupe, with its reliable V8, achieves a similar 15 MPG city and 21 MPG highway. The Porsche Panamera Turbo, another rival, offers slightly better figures around 18 MPG city and 24 MPG highway, but even that requires a lighter touch than most buyers will be willing to give. Those seeking better fuel economy might consider a high-performance hybrid like the BMW M760e xDrive, which nets around 22 MPG combined, but that comes at the cost of some of the raw, unfiltered character that defines the Alpina. Ultimately, the B8 buyer accepts its fuel consumption as part of the price for its unique blend of handcrafted luxury and breathtaking performance.

Tips to maximize efficiency

Use the selectable driving modes. The B8 offers various modes, including an “Eco Pro” setting, that optimizes engine and transmission settings for maximum fuel efficiency. While it won’t transform the B8 into a fuel-sipper, it can make a noticeable difference, especially during steady-state highway cruising.

Pay attention to tire pressure. Maintaining the correct tire pressure, as specified on the door jamb sticker, is critical for both safety and fuel economy. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, especially with temperature changes.

Anticipate traffic flow and avoid unnecessary acceleration. The Alpina B8’s immense power is addictive, but frequent bursts of acceleration quickly diminish fuel economy. Smooth, controlled acceleration ensures you are in the most efficient gear as much as possible.

Minimize idling. Letting the engine idle for extended periods, such as in a drive-through or waiting for someone, wastes fuel. If you anticipate being stationary for more than a minute, turn off the engine. The B8’s restarts are instantaneous.

Before your next purchase, be sure to check ALPINA MPG across all years.

Service your vehicle according to Alpina’s recommended schedule. A properly maintained engine runs more efficiently. Regular oil changes, air filter replacements, and spark plug inspections all help fuel economy.
