20 MPG combined isn’t a headline figure for the 2021 BMW X5 xDrive45e, and anyone expecting Prius-level efficiency from a plug-in hybrid luxury SUV is looking in the wrong place. This is an X5 first, and a fuel saver second, engineered for drivers who want prestige, performance, and a taste of electrification without sacrificing the inherent capabilities of a mid-size SUV. They prioritize a premium driving experience and the BMW badge, and they’re willing to accept middling fuel economy as part of the deal.

City and highway performance

The EPA estimates of 19 MPG in the city and 22 MPG on the highway illustrate the X5 xDrive45e’s split personality. The lower city figure reflects frequent use of the electric motor in stop-and-go traffic, which helps to reduce fuel consumption there. However, the relatively short all-electric range of around 30 miles means the gasoline engine kicks in frequently, especially on longer city drives. On the highway, the gasoline engine takes over as the primary動力源, resulting in a slightly better, but still unremarkable, MPG figure. Drivers who keep the battery charged and make shorter trips will see significantly better overall fuel economy than someone who treats it as a traditional hybrid.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW X5 xDrive45e at $2,900. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. It’s a useful benchmark, but your actual fuel costs will vary depending on your driving habits, location, and how diligently you plug in and use the electric motor. Someone making mostly short trips and keeping the battery topped off will spend far less, while someone with a longer commute who rarely plugs in could easily exceed this estimate.

Real-world expectations

The official EPA numbers provide a baseline, but real-world fuel economy for the X5 xDrive45e depends heavily on how you drive and how often you charge the battery. Frequent charging and using the electric motor for shorter trips can significantly improve overall fuel consumption. Expect to see numbers closer to 40 MPG or higher on days when you rely primarily on electric power. However, longer road trips and a reliance on the gasoline engine will bring the numbers closer to the EPA estimates, or even lower if you drive aggressively. The benefit of a plug-in hybrid lies in its flexibility, but that flexibility requires you to adapt your driving habits to maximize efficiency.

How it compares

The X5 xDrive45e faces competition from other plug-in hybrid SUVs in the luxury segment. The Volvo XC90 Recharge, for example, achieves a combined 27 MPG (with a full battery) and 20 MPG as a hybrid, showcasing the diversity in MPG performance. The Porsche Cayenne E-Hybrid achieves a combined 46 MPGe, which converts to about 21 MPG combined when solely running on gasoline. These figures can help drivers make a buying decision on X5 MPG across all years. These alternatives offer varying degrees of electric range and overall fuel efficiency, demonstrating that the X5 xDrive45e prioritizes performance and luxury alongside its hybrid capabilities. Buyers should also consider the Lincoln Corsair Grand Touring which achieves 78 MPGe or the Lexus NX450h+ which boasts 84 MPGe. Each of these plug-in hybrid SUVs offers a compelling ownership experience but offer widely different levels of fuel efficiency for different drivers and driving conditions.

Tips to maximize efficiency

Take full advantage of the X5 xDrive45e’s electric capabilities. Plug in every night and pre-condition the cabin while still connected to the charger. This minimizes battery drain when you first start driving, maximizing electric range and fuel economy.

Use the various driving modes strategically. Select “Electric” mode for short trips around town, and “Hybrid” mode for longer journeys where the gasoline engine’s efficiency on the highway can be used. Experiment with “Battery Control” mode to reserve battery power for later use in urban areas.

Drive smoothly and avoid aggressive acceleration. The electric motor provides instant torque, which can be tempting to use for quick bursts of speed. But a gentle driving style will conserve energy and extend the electric driving range significantly.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. Maintaining the recommended tire pressure ensures optimal efficiency, as well as better handling and tire wear, which directly affect how much fuel you use.

Minimize unnecessary weight. Remove any items from the cargo area that are not essential, as extra weight increases fuel consumption. While the impact is small, every little bit helps, especially when you’re trying to maximize the benefits of the hybrid powertrain.
