18 MPG combined isn’t going to win the 2017 BMW Alpina B7 xDrive any awards for fuel efficiency, but that figure misses the point of this ultra-high-performance luxury sedan. This isn’t a car purchased by buyers seeking to minimize their carbon footprint. It’s a finely crafted instrument of speed and comfort for those who demand the best, and they understand that comes at a price, both in terms of MSRP and at the pump.

City and highway performance

The EPA estimates the Alpina B7 achieves 16 MPG in the city and 24 MPG on the highway. The city figure reflects the prodigious power being deployed in stop-and-go traffic. The turbocharged 4.4-liter V8 isn’t exactly sipping fuel when accelerating from every light. However, the 24 MPG highway estimate is a respectable number, indicative of the engineering that allows the B7 to cruise effortlessly at high speeds. The smooth-shifting eight-speed automatic transmission helps keep the engine in its most efficient range when possible, but a heavy foot will quickly negate any fuel-saving technology.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 BMW Alpina B7 xDrive is $3,200. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes current national average fuel prices. Keep in mind that premium fuel is required for the Alpina B7, which will increase the cost compared to vehicles that run on regular unleaded.

Real-world expectations

Drivers should expect some variance from the EPA estimates. Those who frequently exploit the B7’s performance capabilities, engaging the Sport or Sport+ driving modes and accelerating aggressively, will likely see fuel economy figures below 18 MPG combined. Conversely, drivers who prioritize fuel efficiency and use the Comfort or Eco Pro modes, and practice gentle acceleration, might achieve slightly better numbers, particularly on long highway drives. But let’s be honest: restraint is not typically associated with Alpina B7 ownership.

How it compares

Compared to other high-performance luxury sedans, the Alpina B7’s fuel economy is within the expected range. For example, the Mercedes-AMG S63 sedan, with its similar twin-turbo V8 engine, achieves around 17 MPG combined. The Porsche Panamera Turbo, while offering comparable performance, also hovers in the 17-19 MPG range. Even the less powerful BMW 750i xDrive manages only slightly better fuel economy, around 21 MPG combined, illustrating that the Alpina’s specialized tuning comes at a price. Buyers in this segment are willing to accept this trade-off; they prioritize performance and exclusivity over maximizing fuel savings and are likely not cross-shopping with a Lexus hybrid.

Tips to maximize efficiency

Use the Eco Pro driving mode. This mode adjusts throttle response, shift points, and climate control settings to prioritize fuel efficiency. While it may slightly dampen the car’s responsiveness, it can make a noticeable difference, especially during city driving.

Practice smooth acceleration and braking. Avoid aggressive starts and hard braking, as these actions consume significantly more fuel. Anticipate traffic flow and maintain a steady speed whenever possible. The Alpina B7’s brakes are certainly capable, but gentle use is far more efficient.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check tire pressure regularly and inflate them to the recommended pressure listed on the door jamb or in the owner’s manual. This is a simple maintenance task that can yield surprisingly positive results.

Minimize idling. Excessive idling wastes fuel. If you expect to be stopped for more than a minute, turn off the engine. Modern engines are designed to start quickly and efficiently, so restarting the engine consumes less fuel than letting it idle.

Consider your route. Plan your trips to avoid congested areas and stop-and-go traffic when possible. Highway driving is generally more fuel-efficient than city driving. Using navigation apps to identify the most efficient route can also help you save fuel.
