17 MPG combined isn’t going to win any awards or impress drivers of hybrid cars. But the 2022 BMW Alpina XB7 isn’t made for fuel efficiency. It’s a hand-finished, high-performance luxury SUV designed to deliver strong acceleration and handcrafted luxury to a very specific customer: one who prioritizes exclusivity and power over saving money at the pump.

City and highway performance

The EPA estimates the XB7 gets 15 MPG in the city and 21 MPG on the highway. That city figure reflects the realities of driving a nearly three-ton SUV through stop-and-go traffic. The 21 MPG highway figure is more attainable during steady cruising, but even then, using the XB7’s 612-horsepower will quickly lower that number. The eight-speed automatic transmission, while incredibly smooth and responsive, is geared for performance, not maximizing fuel economy. The 4.4L twin-turbo V8, hand-assembled by Alpina, is the heart of the experience. It begs to be unleashed, and resisting that urge is a tough ask.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for the 2022 Alpina XB7. This figure is based on driving 15,000 miles per year, with 55% city driving and 45% highway driving, using national average fuel prices. Premium fuel is required for this engine, which significantly impacts the yearly cost. While owners of this vehicle likely aren’t overly concerned with fuel expenses, it’s a tangible reminder of the cost associated with owning a high-performance machine. If you drive more than 15,000 miles, or less, your costs will obviously be proportionate, as will the cost if you don’t keep the same city/highway split. This is a number for comparison more than hard budgeting.

Real-world expectations

Forget about matching EPA estimates if you regularly use the XB7’s performance capabilities. Spirited driving will result in significantly lower fuel economy figures, potentially dipping into the low teens. However, with mindful driving habits and a predominantly highway commute, achieving the EPA’s 21 MPG highway figure is plausible. The XB7’s prodigious power output and substantial curb weight are constants, and demanding acceleration will always come at a price.

How it compares

The Alpina XB7 exists among high-performance luxury SUVs, and its fuel efficiency reflects that. The BMW X7 M50i (before the Alpina treatment) manages a slightly better 19 MPG combined. The Mercedes-AMG GLS 63, another direct competitor, achieves a similar 16 MPG combined, which is common for this vehicle class. Even the less sporty but still luxurious Land Rover Range Rover, depending on the engine choice, gets around 18 MPG combined. For buyers considering the XB7, the difference of 1-2 MPG is unlikely to be a deciding factor. They prioritize the unique Alpina enhancements, the handcrafted interior, and the presence the XB7 commands. For all Bmw fuel economy data, the XB7 is clearly an outlier. If you’re looking at maximizing ALPINA MPG across all years, this is also not the model for you.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel efficiency in the XB7. Avoid abrupt starts and hard braking, allowing the vehicle to build speed gradually. The twin-turbo V8 is responsive even at low RPMs, so there’s no need to bury the throttle unless you’re intentionally seeking maximum performance.

Use the XB7’s adaptive cruise control system on highway drives. This system maintains a consistent speed and distance from the vehicle ahead, minimizing unnecessary acceleration and deceleration, which can significantly improve fuel economy during long trips.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and maintain the recommended pressure listed on the doorjamb or in the owner’s manual.

Minimize idling. If you anticipate stopping for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and avoiding unnecessary idling can save a surprising amount of fuel over time.

Consider using a fuel additive designed to clean fuel injectors. Clean fuel injectors ensure optimal fuel atomization, which can improve combustion efficiency and fuel economy. Consult your owner’s manual or a qualified mechanic for recommended fuel additives.
