20 MPG combined won’t win awards for the 2023 BMW X5 xDrive45e 3.0L 6-cyl, but it’s a number that current BMW owners, and those aspiring to join their ranks, have likely already factored into ownership. This is a mid-size luxury SUV, and more importantly, it’s a plug-in hybrid that prioritizes smooth performance and a premium driving experience over outright fuel efficiency. The X5 xDrive45e offers a blend of power, comfort, and technology, and the 20 MPG represents a trade-off for those qualities.

City and highway performance

The EPA estimates for the X5 xDrive45e, at 19 MPG city and 22 MPG highway, indicate that this vehicle is more efficient in highway driving. This is typical of hybrid powertrains, where electric assist is more effective in stop-and-go city conditions. Out on the open road, the reliable 3.0L inline-six engine does most of the work. With a fully charged battery, drivers can expect better fuel use, especially in shorter city trips, thanks to the electric motor’s ability to handle low-speed driving and acceleration.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW X5 xDrive45e at $2,900. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel price at the time of calculation. Fuel costs will vary based on driving habits, local fuel prices, and how often the vehicle is charged. Those who regularly plug in and maximize electric-only range will see a reduction in their yearly fuel expenses. This data is from all BMW fuel economy data.

Real-world expectations

EPA ratings provide a standardized benchmark, but real-world fuel economy for the X5 xDrive45e will vary. Drivers who consistently use the vehicle’s electric range and prioritize charging can expect to see combined MPG figures much higher than 20. Those who rarely plug in, use the vehicle’s sporty driving modes frequently, or do primarily long-distance highway driving might find themselves at or even slightly below the EPA estimate. Driving style, ambient temperature, and terrain all play a role in the X5’s observed fuel consumption. Monitoring the vehicle’s trip computer and experimenting with different driving modes will help drivers optimize their efficiency.

How it compares

In the competitive mid-size luxury SUV plug-in hybrid segment, the X5 xDrive45e stacks up against rivals like the Volvo XC60 Recharge, which boasts a combined EPA rating of 28 MPG while blending gasoline and electric range. The Lincoln Corsair Grand Touring also competes here, reporting 27 MPG combined in hybrid mode, according to the EPA. The Land Rover Range Rover Sport P440e offers more power and capability but achieves a combined rating of around 19 MPG. The X5’s 20 MPG lags behind some competitors on paper, but its emphasis on performance and driving engagement remains a key differentiator for buyers who prioritize these aspects.

Tips to maximize efficiency

Plug in whenever possible to maximize the vehicle’s electric range to take advantage of the X5 xDrive45e’s charging capabilities. This is the most effective way to reduce fuel consumption, especially on shorter trips.

Experiment with the different driving modes. Eco Pro mode is designed to optimize fuel efficiency by adjusting throttle response, transmission shift points, and climate control settings. Comfort mode balances performance and efficiency, while Sport mode prioritizes performance at the cost of fuel economy. Understanding how each mode affects fuel consumption will allow you to select the most appropriate setting for different driving conditions and find the X5 MPG across all years.

Avoid aggressive acceleration and braking, especially when operating in hybrid mode. Smooth, gradual inputs will allow the electric motor to assist more effectively, reducing the strain on the gasoline engine and improving fuel efficiency.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check tire pressure regularly and inflate to the levels specified on the doorjamb placard.

Reduce unnecessary weight. Carrying excessive cargo in the vehicle adds extra weight, which increases fuel consumption. Remove any items that are not essential to improve overall efficiency.
