While 25 MPG combined won’t break any fuel economy records, it’s a respectable compromise for the 2015 BMW ActiveHybrid 7L. This car isn’t for those who want maximum efficiency above all else. The ActiveHybrid 7L appeals to a specific buyer: someone who is after the flagship luxury experience of the long-wheelbase 7 Series, but with a slightly lessened reliance on fossil fuels. These buyers want prestige, comfort and a touch of lower fuel costs in a large, luxurious sedan, and realize some trade-offs are required.

City and highway performance

The EPA figures reflect the ActiveHybrid 7L’s blended powertrain. The 22 MPG city rating shows the benefits of the electric motor helping the 3.0L inline-six during stop-and-go driving. The electric motor can shoulder some of the work and even allow for brief periods of pure-electric driving. On the open road, the 30 MPG highway figure demonstrates the engine’s ability to cruise efficiently. Its eight-speed automatic transmission helps keep the engine in its optimal efficiency range at higher speeds. The hybrid system helps most in cities. This performance split aligns with typical ActiveHybrid 7L use, as it handles city streets and highway miles well.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 BMW ActiveHybrid 7L at $2,300. This is based on driving 15,000 miles per year, using 55% city and 45% highway driving, and using national average fuel prices. This is a useful way to compare the running costs of different vehicles. An all-electric car would obviously cost less to fuel each year, but considering the size, luxury and performance, $2,300 might be acceptable to the target buyer. Owners can monitor actual fuel expenses and adjust driving habits to stay within their budget.

Real-world expectations

The EPA figures provide a standardized baseline, but real-world fuel economy will vary depending on individual driving habits, traffic, and climate. Hard acceleration, frequent hard braking, and long idling will hurt efficiency. Extreme temperatures can affect battery and engine efficiency, reducing fuel economy. The ActiveHybrid 7L’s hybrid system tries to match the EPA numbers in normal conditions, but expect deviations based on these things.

How it compares

The 2015 ActiveHybrid 7L competes with other flagship luxury sedans, some with hybrid versions. A 2015 Lexus LS 600h L, another hybrid luxury sedan, gets 20 MPG combined. The Mercedes-Benz S-Class, not available as a hybrid in 2015, usually gets lower fuel economy in its non-hybrid V8 models, around 20 MPG combined. Looking at all Bmw fuel economy data, the hybrid drivetrain offers a fuel economy boost compared to the conventional 7 Series models of the same year. The ActiveHybrid 7L is a middle ground: more efficient than a gasoline-powered flagship, but not as frugal as smaller hybrids.

Tips to maximize efficiency

Drive in electric mode when you can. In city driving, accelerate moderately and let the electric motor give the initial boost. Gentle starts and stops help you stay in electric-only mode, improving fuel economy in stop-and-go traffic.

Use the driving modes. The ActiveHybrid 7L has driving modes like “Eco Pro,” “Comfort,” and “Sport.” Eco Pro prioritizes efficiency by changing throttle response, transmission shift points, and climate control. Using this mode when you can improve fuel economy.

Check tire pressure. Underinflated tires increase rolling resistance, reducing fuel efficiency. Check tire pressures monthly and inflate them to the recommended levels on the doorjamb or in the owner’s manual.

Reduce weight in the car. Extra weight reduces fuel economy. Remove unnecessary items from the trunk and passenger area. Every extra pound increases fuel use.

Plan routes to avoid traffic. Avoiding congested areas can improve fuel economy. Use navigation to find the most efficient routes, even if they are longer. Consistent speed and fewer stops will always maximize MPG.
