19 MPG combined isn’t going to win any awards, but for the 2018 BMW Alpina B7 xDrive, it’s almost beside the point. This isn’t a car purchased for its fuel efficiency. It’s bought for its sheer performance and meticulously crafted luxury. The buyer appreciates fine watches, bespoke tailoring, and effortless power. Fuel economy is a lesser concern, easily muted by the sound of the twin-turbo V8.

City and highway performance

The EPA estimates the 2018 Alpina B7 xDrive at 16 MPG in the city and 25 MPG on the highway. The difference is largely due to the Alpina’s thirst in stop-and-go driving. The instant torque and available power encourage frequent acceleration, impacting city fuel consumption. On the open road, however, the B7’s aerodynamics and powertrain management allow it to stretch a gallon impressively, especially when cruising at consistent speeds. The eight-speed automatic transmission plays a key role, keeping the engine in its most efficient range when cruising.

Annual fuel cost

The estimated annual fuel cost for the 2018 BMW Alpina B7 xDrive is $3,050, according to the EPA. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on driving habits, fuel prices, and the type of fuel used. Premium fuel is mandatory, increasing running costs. This is a figure the Alpina B7 owner considers the cost of doing business for exclusivity and performance. You can view all Bmw fuel economy data for a comparison, but the Alpina B7 is in a unique category.

Real-world expectations

While the EPA figures provide a baseline, real-world MPG for the Alpina B7 can change. Aggressive driving and frequent use of the car’s power results in numbers closer to 14-15 MPG. But a driver who adopts a relaxed style and spends more time on the highway might see figures closer to the EPA’s 25 MPG highway estimate. Fuel economy with a car like this is driver-dependent and reflects how often the performance potential is tapped. Remember to check ALPINA MPG across all years.

How it compares

The Alpina B7 doesn’t have direct rivals. Its blend of performance, luxury, and exclusivity makes it unique. Still, considering other high-performance luxury sedans provides context. The Mercedes-AMG S63, another twin-turbo V8, achieves a similar 17 MPG combined. The Porsche Panamera Turbo fares slightly better at 18 MPG combined, but it caters to a more sporting driver. Even BMW’s own M760i xDrive, with its V12 engine, isn’t significantly more economical. The slight differences in fuel economy are small compared to the different driving experiences that each of these vehicles offer. The Alpina B7 emphasizes smooth power delivery, sacrificing some fuel efficiency for effortless speed.

Tips to maximize efficiency

Gentle acceleration is key. The Alpina B7’s twin-turbo V8 provides torque, meaning you don’t need to push the throttle to get up to speed. Smooth acceleration will reduce fuel consumption, especially in city driving. Treat the accelerator pedal with respect and you’ll be surprised at how much more economical the B7 can be.

Anticipate traffic flow and avoid unnecessary braking. Maintaining speed minimizes the need for acceleration, where the Alpina B7 consumes the most fuel. Look ahead, anticipate changes in traffic, and lift off the throttle early to coast whenever possible. This driving style also makes for a smoother and more enjoyable experience.

Regularly check tire pressures. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Ensure your tires are inflated to the recommended pressure, which can often be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Properly inflated tires also improve handling and extend tire life.

Take advantage of the B7’s Eco Pro mode. Eco Pro mode can help improve fuel economy by optimizing engine settings, transmission mapping, and climate control operation. It won’t turn the B7 into a Prius, but it can provide an improvement in fuel efficiency, especially on longer journeys.
