BMW 550e xDrive Electric vs Gasoline: Cost per Mile Compared
The 2027 BMW 550e xDrive sedan, a midsize plug-in hybrid electric vehicle (PHEV), offers buyers a combined energy efficiency rating of 25 MPGe, balancing electric and gasoline power. However, when analyzing the per-mile energy costs, electric driving currently costs more than gasoline for this model, resulting in negligible annual fuel savings under typical conditions.
Key Findings
- The BMW 550e xDrive achieves a combined 25 MPGe according to EPA ratings.
- U.S. residential electricity costs average 18.4400 cents/kWh.
- U.S. gasoline prices average $3.9320 per gallon.
- Electricity for 100 miles in the 550e costs about $24.86, higher than the gasoline cost for the same distance at $14.04.
- Estimated annual fuel savings by driving electric in the 550e are currently negligible, at $0.
Understanding the BMW 550e xDrive Efficiency
The combined 25 MPGe rating reflects the energy consumed when the 550e uses both its electric motor and gasoline engine. MPGe (miles per gallon gasoline equivalent) is a standard EPA metric used to compare energy consumption across electric and combustion vehicles. This rating indicates moderate efficiency for a PHEV in the midsize sedan category but is lower than many full battery electric vehicles.
Electricity Versus Gasoline Energy Costs
The cost analysis compares U.S. average residential electricity prices of 18.4400 cents per kWh against gasoline prices averaging $3.9320 per gallon. Using EPA data for the 550e, a full 100-mile drive costs roughly $24.86 in electricity but only $14.04 in gasoline. This higher electric cost per mile may surprise those expecting electric driving always to be cheaper.
Potential Reasons For Higher Electric Costs
This counterintuitive result may stem from the 550e’s design as a plug-in hybrid rather than a pure EV. Its battery capacity and electric-range limitations require frequent gasoline use, and the combined efficiency includes the gasoline-powered portion. Additionally, local electricity costs vary considerably, affecting this calculation. For buyers in areas with lower electricity prices, the cost gap might narrow.
Who Should Consider the 550e xDrive?
Buyers looking for a premium midsize sedan with flexible fueling options may find the 550e appealing. It allows electric driving for short daily trips and gasoline power for longer distances without range anxiety. However, buyers prioritizing lower fuel expenses per mile might prefer gasoline-only models or fully electric vehicles with better electricity cost efficiency.
Limitations and Cost Considerations
This analysis focuses solely on fuel/energy costs, excluding maintenance, incentives, or depreciation which also impact total ownership cost. The estimated annual fuel savings currently show no advantage for the 550e when comparing electric versus gasoline energy expenses for typical use, emphasizing the importance of driving patterns and local energy prices in the economics of PHEVs.

Frequently Asked Questions
What is the combined MPGe of the BMW 550e xDrive sedan?
The EPA rates the 550e with a combined efficiency of 25 MPGe.
How does the 550e’s electric cost per 100 miles compare to gasoline?
Electricity costs approximately $24.86 per 100 miles, which is higher than the gasoline cost of $14.04 for the same distance.
Are there significant annual fuel savings when driving the 550e electric versus gasoline?
Currently, estimated annual savings due to electric driving are negligible, shown as $0 under average assumptions.
Why does the 550e have a higher cost per mile on electricity compared to gasoline?
Its design as a plug-in hybrid with limited electric-only range and higher local electricity costs contribute to higher per-mile electric driving costs compared to gasoline.
Is the BMW 550e xDrive a cost-effective choice for reducing fuel expenses?
Under average U.S. energy prices and typical driving, it does not offer fuel cost savings solely through electric driving, but offers flexibility for electric and gasoline fueling.
Conclusion
The 2027 BMW 550e xDrive sedan offers a balance of electric and gasoline power with a combined EPA rating of 25 MPGe. However, under current U.S. energy prices, its electricity cost per 100 miles exceeds the gasoline cost, neutralizing typical fuel savings expected from electric driving. Buyers should weigh this energy cost dynamic against their driving patterns and fueling preferences. For those valuing flexibility or limited electric-range plug-in capability, the 550e remains a compelling choice, but those prioritizing electric cost-efficiency might consider full battery EV alternatives or gasoline models.
