The 2024 BMW X5 xDrive40i’s 25 MPG combined fuel economy is a calculated balance between performance, luxury, and fuel savings. This figure often lands in an acceptable middle ground for those drawn to the X5’s power, technology and road presence.

City and highway performance

The EPA estimates the X5 xDrive40i achieves 23 MPG in the city and 27 MPG on the highway. These numbers reflect the characteristics of its 3.0-liter turbocharged inline-six engine, paired with an eight-speed automatic transmission (S8). The engine’s strong low-end torque and the transmission’s smooth, precisely spaced ratios allow for easy urban driving, while the higher gears help with respectable efficiency on the open road. These figures show that while the X5 is capable of quick acceleration and dynamic handling, it still prioritizes efficient cruising at highway speeds.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 BMW X5 xDrive40i is estimated at $2,300. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and factoring in the national average fuel price. It is a useful estimate to gauge the car’s fuel consumption impact to your budget. However, individual driving habits, local fuel prices, and the grade of fuel used can all affect the real-world cost.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy inevitably varies. The X5 xDrive40i’s turbocharger responds readily to throttle input, which means drivers who accelerate quickly will likely see figures below the EPA estimates. But those who prioritize smooth acceleration and consistent speeds can often match or even slightly exceed those numbers. Driving style, traffic conditions, and even tire pressure play a role in the MPG you ultimately experience. To get a clearer picture of potential running costs, visit X5 MPG across all years.

How it compares

The fuel efficiency of the X5 xDrive40i positions it competitively within the mid-size luxury SUV segment. The Mercedes-Benz GLE 350 4MATIC achieves a similar 22 MPG combined, and the Audi Q7 45 TFSI gets slightly better at 21 MPG city and 25 MPG highway (23 MPG Combined). Land Rover’s Range Rover Sport P360 achieves an identical 25 MPG combined. These minor differences often aren’t the decisive factor for buyers in this segment who are typically more focused on features, performance, and brand cachet. But knowing these metrics helps with a complete understanding. For all Bmw fuel economy data, see our dedicated section.

Tips to maximize efficiency

Engage the X5’s “Eco Pro” driving mode. This mode remaps the throttle response, adjusts shift points, and reduces the climate control system’s energy consumption. It’s designed to optimize fuel efficiency, particularly during everyday commuting, without significantly hindering the driving experience.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the manufacturer’s recommended level, found on the doorjamb sticker.

Anticipate traffic flow and avoid unnecessary acceleration and braking. The X5’s responsiveness can be addictive, but smooth, gradual inputs are far more fuel-efficient than abrupt bursts of speed followed by hard braking. Look ahead and maintain a consistent pace whenever possible.

Minimize idling. Excessive idling wastes fuel and increases emissions. If you anticipate being stopped for more than a minute or two, turn off the engine. The X5 has a quick restart function when you’re ready to move again.

Consider limiting roof rack use. Roof racks, especially when loaded, create significant aerodynamic drag, which negatively impacts fuel economy, particularly at highway speeds. Remove them when not in use to improve the X5’s efficiency.
