88 MPG combined. That figure immediately highlights the 2024 BMW i7 xDrive60 Sedan with 21-inch wheels as a standout in the luxury EV market, a segment not traditionally known for prioritizing outright efficiency. This isn’t about hypermiling; it’s about minimizing compromise. This flagship sedan delivers limousine-like comfort, cutting-edge technology, and surprisingly responsible energy consumption.

City and highway performance

The EPA estimates for the i7 xDrive60 reveal a nuanced picture of its efficiency. The city MPG of 86 reflects the regenerative braking system’s effectiveness in stop-and-go traffic. This allows the i7 to recapture kinetic energy normally lost during braking, feeding it back into the battery pack and extending range. The highway figure of 91 MPG demonstrates the car’s aerodynamic efficiency and the electric powertrain’s inherent ability to maintain consistent efficiency at higher speeds. These numbers reflect ideal testing conditions, but they provide a useful benchmark.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW i7 xDrive60 at $850. This figure is based on driving 15,000 miles per year and using national average electricity prices, allowing consumers to directly compare the running costs of different vehicles. Energy prices fluctuate and individual driving habits vary, but $850 is a tangible data point highlighting potential savings compared to a similarly sized, conventionally powered luxury sedan. Consider the cost of premium fuel, plus the increased maintenance, of a V8-powered alternative: The i7’s advantage becomes clear.

Real-world expectations

While the official EPA figures provide a solid starting point, real-world efficiency will vary based on driving style, ambient temperature, and terrain. Aggressive acceleration, frequent climate control use, and sustained high-speed driving will all impact the i7’s range and fuel economy. Employing a smoother driving style, preconditioning the cabin while plugged in, and using the car’s energy-saving modes can help maximize efficiency and get closer to the EPA estimates. Expect some fluctuation; that 88 MPG combined is an achievable target, but disciplined driving habits are necessary. It’s worth considering tire pressure, and making sure your 21-inch wheels are properly inflated.

How it compares

The i7’s efficiency stands out even within the electric luxury sedan segment. The Mercedes-Benz EQS 450+ Sedan achieves an EPA-estimated 97 MPGe combined, a slight edge over the i7 xDrive60. However, the i7 xDrive60 offers more aggressive styling for buyers who aren’t sold on the EQS’s distinctive profile. The Genesis G80 Electrified boasts 97 MPGe combined as well, but it comes with a smaller footprint and lacks the opulence of the i7. These comparisons matter because buyers in this segment often have multiple vehicles and consider a range of factors beyond pure efficiency, seeking the best balance of luxury, technology, and environmental responsibility.

Tips to maximize efficiency

Engage “Efficiency Mode” whenever possible. This driving mode optimizes various vehicle systems, including throttle response and climate control, to minimize energy consumption. While it might slightly reduce performance, the gains in range can be significant, especially on longer journeys. Consider this your default driving mode outside of spirited backroad drives.

Take advantage of regenerative braking. The i7 offers adjustable levels of regenerative braking, allowing you to customize the amount of deceleration when lifting off the accelerator. Experiment with different settings to find the level that suits your driving style and maximizes energy recapture. In many cases, you can drive around town almost entirely with one pedal.

Precondition the cabin while plugged in. Heating or cooling the interior while the car is still connected to a charger draws power from the grid rather than the battery, preserving range. This is beneficial in extreme temperatures, helping to maintain optimal battery performance and efficiency.

Plan your routes strategically, taking into account charging locations. Using the BMW navigation system, or other apps offering directions and charging information, allows you to efficiently plan trips and minimize range anxiety. Identifying en route charging stations and factoring in charging times will ensure a smooth and stress-free driving experience.

Limit unnecessary weight and aerodynamic drag. Removing excess cargo from the vehicle reduces the overall load, improving efficiency. Ensuring proper tire inflation and avoiding the use of roof racks or other accessories that increase aerodynamic drag helps to minimize resistance and maximize range. This may sound obvious, but it is easy to forget when you’re carrying passengers.
