19 MPG combined won’t make the 2023 BMW Alpina B8 Gran Coupe a fuel-sipping champion, but let’s be realistic. This is a handcrafted, high-performance four-door coupe that’s more likely to be found on canyon roads or effortlessly cruising autobahns than hypermiling in city traffic. The buyers who choose this car aren’t prioritizing fuel efficiency; they’re after exclusivity, blistering acceleration, and a bespoke driving experience that few other vehicles can offer.

City and highway performance

The Alpina B8 Gran Coupe’s EPA ratings break down to 17 MPG in the city and 24 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the 4.4-liter twin-turbo V8 inevitably drinks more deeply from the fuel tank. However, the highway number is more respectable, showcasing the engine’s ability to cruise efficiently at higher speeds.

The smooth-shifting eight-speed automatic transmission also helps, optimizing gear selection for both performance and fuel conservation when possible. Even on the highway, a heavy foot will quickly diminish those numbers. The Alpina B8 Gran Coupe begs to be driven with enthusiasm, and resisting that urge is a challenge.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW Alpina B8 Gran Coupe at $3,050. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. Real-world costs will vary depending on individual driving habits, local fuel prices, and the type of fuel used. The B8 Gran Coupe requires premium fuel, adding to the overall expense. Some drivers will exceed the 15,000-mile estimate, while others may drive less, directly impacting their yearly fuel expenditure. The ALPINA MPG across all years reflects a similar level of fuel consumption.

Real-world expectations

While the EPA estimates are a good starting point, expect real-world fuel economy to fluctuate based on driving style and conditions. Frequent bursts of acceleration, extended idling, and aggressive cornering will all contribute to lower MPG. Conversely, smooth, consistent driving at moderate speeds will yield results closer to the EPA’s highway figure.

It’s also important to consider the impact of optional equipment and accessories. Added weight, such as larger wheels or aftermarket modifications, can negatively influence fuel efficiency. Tire pressures also play a role; maintaining proper inflation is crucial for optimal fuel economy.

How it compares

In the realm of high-performance four-door coupes, the Alpina B8 Gran Coupe’s fuel economy is generally in line with its competitors. The Mercedes-AMG GT 63 S, for example, delivers similar performance with an EPA rating of 15 MPG city and 21 MPG highway. The Porsche Panamera Turbo S offers comparable power and luxury, but its fuel economy is also in the same ballpark, around 15 MPG city and 23 MPG highway.

Even the all-electric Porsche Taycan Turbo S, while offering zero-emission driving, comes with its own set of range-related considerations. Ultimately, the Alpina B8 Gran Coupe buyer is accepting moderate fuel consumption in exchange for an exceptional driving experience that prioritizes performance and exclusivity.

Tips to maximize efficiency

Adopt a smooth and progressive driving style. Avoid abrupt acceleration and braking, anticipate traffic flow, and maintain a steady speed whenever possible. The Alpina B8 Gran Coupe’s powerful engine responds readily to even slight throttle inputs, so learn to modulate your foot pressure to avoid unnecessary fuel consumption.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly, especially before long trips, and inflate them to the manufacturer’s recommended specifications.

Reduce unnecessary weight in the vehicle. Remove any items that are not essential, such as golf clubs, sporting equipment, or unused cargo. Excess weight puts a strain on the engine and reduces fuel efficiency.

Minimize idling. Prolonged idling consumes fuel without actually moving the vehicle. If you anticipate being stationary for more than a minute or two, turn off the engine. Modern engines are designed to start quickly and efficiently, so restarting is more fuel-efficient than idling.

Plan your routes strategically. Avoid congested areas and routes with frequent stop-and-go traffic. Opt for routes with smoother traffic flow and consistent speeds to maximize fuel efficiency. Using navigation apps to identify and avoid traffic bottlenecks can save you both time and fuel.
