87 MPG combined is a remarkable figure, and for the 2025 BMW iX xDrive40 with 22-inch wheels, it reflects excellent electric SUV efficiency and BMW luxury and performance. This isn’t a bare-bones economy car, it’s a stylish, spacious, technologically advanced crossover designed for drivers who want both low fuel costs and a premium driving experience. The buyers of the iX aren’t only focused on the lowest possible running costs, they are seeking an emission-free vehicle that doesn’t compromise on the features, comfort, and performance they expect from a BMW, and the 2025 iX delivers exactly that.

City and highway performance

The EPA estimates the iX xDrive40’s efficiency at 89 MPG in the city and 85 MPG on the highway. The slightly higher city rating shows how well the regenerative braking system works. Stop-and-go traffic allows the iX to recapture energy normally lost during braking, feeding it back into the battery pack and extending its range. On the highway, where there’s less opportunity for regenerative braking, the number dips slightly, but it’s still an impressive figure demonstrating the efficiency of the electric powertrain even at higher, consistent speeds. This performance profile makes the iX an ideal choice for those who spend a significant portion of their time commuting in urban environments while still needing the range to tackle longer road trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW iX xDrive40 (with 22-inch wheels) at $850. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average electricity prices for charging. This figure is particularly attractive for buyers who may be coming from a gasoline-powered luxury SUV, where annual fuel costs can easily reach two or three times that amount. It highlights the long-term savings potential of switching to an electric vehicle, especially for those who do a lot of driving. While home charging infrastructure costs may factor in, the day-to-day savings are substantial.

Real-world expectations

The EPA ratings provide a standardized benchmark, real-world MPG (or MPGe) can vary based on driving style. Aggressive acceleration and hard braking consume more energy, reducing efficiency. Environmental conditions also affect range; cold weather can decrease battery performance, while climate control systems also draw power. and carrying heavy loads or frequently using the iX’s performance capabilities will impact energy consumption. Even with these variables, drivers can reasonably expect to achieve figures close to the EPA estimates by adopting energy-conscious driving habits and using the iX’s range-extending features.

How it compares

The iX competes in a segment with other luxury electric SUVs, and its energy efficiency is a key differentiator. For example, the Audi e-tron, depending on the model year, achieves around 78 MPG combined, while the Jaguar I-Pace comes in around 76 MPG. Even the Tesla Model X, despite Tesla’s reputation for efficiency, typically achieves figures slightly lower, around 102 MPG combined for the Long Range model but it comes with a higher price tag. The Cadillac Lyriq, another strong contender, achieves around 96 MPG combined. The iX stands out because of BMW’s handling dynamics, the high-end interior appointments, and consistent MPG across all years, making is an appealing offer when looking at all Bmw fuel economy data.

Tips to maximize efficiency

Use the BMW’s driving modes to optimize energy consumption. Engage “Eco Pro” mode for everyday driving, this setting adjusts throttle response and other parameters to prioritize efficiency. “Sport” mode unleashes the iX’s full power, but it also significantly impacts range.

Precondition the battery and cabin temperature while the iX is plugged in. This uses energy from the grid rather than draining the battery, maximizing range, especially in cold weather. Set a charging schedule to take advantage of off-peak electricity rates, which can significantly lower home charging costs.

Employ regenerative braking to its fullest potential. Anticipate traffic conditions and coast whenever possible, allowing the iX to recapture kinetic energy through regenerative braking. One-pedal driving, if enabled, further enhances this effect, increasing range and reducing brake wear.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces range. Check tire pressures regularly and inflate them to the manufacturer’s recommended levels, found on the doorjamb sticker. and consider using the 20 inch wheels when purchasing to get the maximum MPG.

Minimize unnecessary weight. Remove non-essential items from the vehicle to reduce the load on the motor and improve efficiency. Even small reductions in weight can cumulatively improve the iX’s MPGe. Also refer to the IX MPG across all years as this will change slightly as they make improvements along the way.

The 2025 BMW iX xDrive40 with 22-inch wheels attracts a customer who appreciates BMW engineering, design, and driving dynamics, and prioritizes electric benefits without sacrificing the upscale experience they expect.
