City and Highway Performance

The EPA estimates of 87 MPG in the city and 93 MPG on the highway highlight the i7’s exceptional efficiency in varied driving conditions. Electric vehicles often excel in city driving because of regenerative braking, which recaptures energy during deceleration and braking, and the i7 is no exception. Its ability to recoup energy translates to a higher MPG equivalent in stop-and-go traffic, where a conventional gasoline engine would be at its least efficient. The impressive highway number reveals the efficiency of the electric drivetrain at higher speeds, minimizing energy consumption through optimized aerodynamics and a highly efficient motor. These ratings demonstrate that the i7 owner can embark on long road trips with minimal range anxiety while enjoying a quiet and exceptionally smooth ride.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW i7 xDrive60 at precisely $850. This figure is based on driving 15,000 miles per year, with a specific percentage split between city and highway driving, and assumes the national average electricity price.

Compared to even the most fuel-efficient gasoline-powered luxury sedans, the i7 offers significant savings. Electricity prices can vary greatly depending on your location and time of day, so the actual cost may be higher or lower, but the $850 figure gives a good indication of the potential for financial savings.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPG can vary depending on several factors like driving style, ambient temperature, and the use of climate control. More aggressive driving, such as frequent hard acceleration, will deplete the battery faster. Extreme temperatures, hot or cold, can also reduce range, as the car needs to use energy to heat or cool the battery pack. Frequent use of the i7’s many luxury features, such as heated seats and massage functions, will also contribute to increased energy consumption.

Despite these factors, the i7’s energy management system and efficient electric drivetrain should allow most drivers to achieve close to the EPA estimates under normal driving conditions, especially when the latest software updates are installed.

How it compares

The electric luxury sedan market is becoming increasingly competitive, but the I7 stands out with its exceptional fuel economy. The Mercedes-Benz EQS 450+ Sedan, for instance, is rated at 97 MPGe combined. While this appears slightly better, it’s crucial to remember that “MPGe” is a metric designed to compare electric vehicles with gasoline ones, and real-world results may differ.

Comparing with gasoline vehicles can also provide additional context. The BMW 740i, equipped with a traditional gasoline engine, achieves around 28 MPG combined. Choosing the i7 will yield much better fuel economy than its gasoline counterpart, while still offering similar levels of luxury and technology. You can also compare the I7 MPG across all years.

Tips to maximize efficiency

Take advantage of the i7’s regenerative braking settings. Experiment with different levels of regeneration to find a setting that suits your driving style and allows you to recapture as much energy as possible. The highest setting allows for “one-pedal driving,” enabling you to slow down or stop the car simply by lifting off the accelerator.

Precondition the cabin while the car is still plugged in. This allows you to heat or cool the interior without drawing energy from the battery, preserving range, especially during winter or summer.

Pay attention to tire pressure. Maintaining the correct tire pressure, as indicated on the door jamb, reduces rolling resistance and improves efficiency. Regularly check and adjust your tire pressure, especially before long trips.

Avoid aggressive acceleration and braking. Smooth, gradual driving conserves energy and extends range. Anticipate traffic conditions and avoid unnecessary hard acceleration, which depletes the battery more quickly.

Consider using the i7’s ECO PRO driving mode. This mode optimizes the vehicle’s systems for maximum efficiency, limiting power output and adjusting climate control settings to conserve energy. For all Bmw fuel economy data, check out FuelEconomyHub.
