23 MPG combined is what you can expect from the 2022 BMW X4 M40i. This isn’t a number that will impress those prioritizing less gas above all else, but for those who want a sporty, aggressively styled crossover with a potent inline-six engine, it’s a compromise they’re likely willing to make. Buyers in this segment prioritize performance and image, and the X4 M40i delivers both. The priority is how quickly it merges onto the highway, not how many miles it squeezes from each gallon.

City and highway performance

The X4 M40i’s EPA ratings break down to 21 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go driving, where the engine is frequently idling or accelerating from a standstill. The highway MPG showcases the engine’s efficiency at consistent speeds, though even at 70 mph, you can feel the powertrain’s latent eagerness. Don’t expect to match the higher highway figure if you’re constantly dipping into the engine’s power reserves to pass or merge aggressively. Still, these figures provide a reasonable baseline for estimating fuel consumption in typical driving conditions.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2022 BMW X4 M40i. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Remember that premium fuel is recommended for optimal performance, meaning you’ll be paying more at the pump than someone filling up with regular unleaded. Your actual fuel costs may vary depending on your driving habits, fuel prices in your area, and the number of miles you drive annually.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates from these estimates. Factors such as driving style, traffic conditions, and even the weather can affect how many miles you get per gallon. Aggressive acceleration, frequent braking, and prolonged idling will decrease fuel efficiency, while smooth, steady driving will help you get closer to the EPA numbers. Pay close attention to your driving habits and adjust as needed to improve your fuel economy.

How it compares

The X4 M40i is in a competitive segment, and comparing its fuel economy to rivals is important for buyers. The Porsche Macan S, for example, which offers a similar blend of performance and luxury, achieves a combined 19 MPG. The Audi SQ5, another strong contender, manages a slightly better 21 MPG combined. Even within the BMW family, the more traditionally shaped X3 M40i achieves an identical 23 MPG combined, underscoring that the X4’s sloping roofline doesn’t markedly impact efficiency. These variations highlight that while the X4 doesn’t lead the pack in fuel efficiency, its numbers are reasonably competitive given its performance capabilities and distinct design. If fuel economy is your top priority, exploring all Bmw fuel economy data might reveal a better fit. However, for those drawn to the X4’s unique blend of sportiness and coupe-like styling, the fuel consumption is part of the trade-off.

Tips to maximize efficiency

Use the X4 M40i’s driving modes. The “Eco Pro” mode optimizes the powertrain for fuel efficiency by adjusting throttle response and shift points. While it might slightly diminish the vehicle’s sporty feel, it can noticeably improve MPG, especially during longer highway drives.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Keeping your tires properly inflated not only improves gas mileage, but also enhances handling and extends tire life.

Avoid unnecessary idling. Letting the engine idle for extended periods wastes fuel. If you’re stopped for more than a minute or two, turn off the engine. Modern engines warm up quickly, so there’s no need to idle them beforehand, and restarting consumes less fuel than prolonged idling does.

Be mindful of your acceleration and braking. Sudden, hard acceleration and braking significantly impact fuel economy. Instead, accelerate smoothly and gradually, and anticipate traffic conditions to minimize the need for abrupt stops. Gentle inputs will result in a more efficient and enjoyable driving experience.

Consider using cruise control on the highway. Maintaining a consistent speed helps to optimize fuel consumption. Cruise control can help you avoid unintentional speed fluctuations, leading to a more even and efficient burn of fuel.
