86 MPG combined immediately grabs attention, especially for a vehicle the size and style of the 2024 BMW iX xDrive40. This all-electric SUV delivers exceptional efficiency, largely negating range anxiety for the typical luxury car buyer and radically reducing ongoing running costs compared to gasoline-powered competitors.

City and highway performance

The EPA numbers offer a detailed look at the iX xDrive40’s efficiency. The iX is rated at 87 MPG in the city and 85 MPG on the highway, demonstrating that its electric powertrain is optimized for both stop-and-go traffic and sustained cruising. The similar numbers show BMW’s ability to flatten the efficiency curve of electric consumption based on different driving types. Regenerative braking is a core element in making a heavy vehicle so efficient in urban driving, recovering energy with every press of the brake pedal.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW iX xDrive40 at exactly $900. This figure is based on driving 15,000 miles per year and using the national average electricity price. Electricity prices vary considerably by region, but the $900 figure is a useful benchmark for comparing the iX’s running costs against those of gasoline-powered SUVs. This low, fixed annual cost will be a selling point for many buyers, considering the volatility of gasoline prices.

Real-world expectations

While the EPA provides a standardized measurement, real-world MPG can vary based on driving style, weather conditions, and terrain. Aggressive acceleration, frequent use of climate control, and driving in extremely cold temperatures can all reduce the iX’s efficiency. On the other hand, gentle acceleration, preconditioning the cabin while plugged in, and driving modes that prioritize efficiency can help owners achieve or even exceed the EPA estimates. Intelligent route planning that incorporates charging stops is key to long road trips. The iX is very efficient in the real world, encouraging different driving habits, but there’s no inherent frustration in trying to live up to a laboratory number.

How it compares

The iX xDrive40 is in a competitive segment, and its efficiency compares favorably. For example, the Audi e-tron boasts a combined EPA rating of just 78 MPG. The Jaguar I-Pace achieves 76 MPG combined. Even the Tesla Model X, while offering impressive range and performance, only manages around 102 MPG combined in its base trim. The Cadillac Lyriq’s numbers are also very similar. The iX xDrive40’s efficiency is a clear advantage, particularly for buyers who prioritize lower running costs alongside luxury and performance. As you refine your purchase research, looking at all Bmw fuel economy data will help contextualize what you’re getting with this car. And investigating IX MPG across all years will demonstrate the level of consistency BMW delivers with this model.

Tips to maximize efficiency

Use the iX’s regenerative braking system on every deceleration. Experiment with the different levels of regen to find the setting that best suits your driving style and maximizes energy recovery. Use BMW’s ConnectedDrive services for route planning, which can optimize your route for efficiency and suggest charging stops along the way.

Precondition the iX’s cabin while it’s plugged in, especially during cold weather. This warms or cools the interior using grid power rather than draining the battery, preserving range. Use the “Efficiency” driving mode to limit power output and optimize various vehicle systems for maximum efficiency while driving in the city.

Minimize aggressive acceleration and braking. Smooth, consistent driving conserves energy and improves range, something easy enough in a vehicle as quiet and comfortable as this.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, reducing efficiency. Check your tire pressure regularly and inflate to the recommended level.

Remove unnecessary weight from the vehicle. The heavier the iX, the more energy it takes to move it. Unload any cargo or items that you don’t need to carry, as this can incrementally improve your consumption.
