28 MPG combined is a perfectly acceptable figure for the 2024 BMW 540i xDrive Sedan, a vehicle that prioritizes effortless power and all-weather confidence over simply saving fuel. This isn’t a hybrid, it isn’t trying to be, and its target demographic, affluent professionals seeking a refined driving experience, understand the trade-off involved. The 540i xDrive isn’t bought to save money; it’s bought for the smooth surge of its turbocharged inline-six and the surefootedness of its all-wheel-drive system. Fuel economy is a consideration, but not the main reason for purchase.

City and highway performance

The EPA estimates the 2024 BMW 540i xDrive Sedan achieves 26 MPG in the city and 33 MPG on the highway. The difference tells a story. The city figure highlights the engine’s ability to operate efficiently in stop-and-go conditions, aided by the smooth-shifting eight-speed automatic transmission (S8). The 33 MPG highway rating demonstrates the car’s comfortable cruising ability, where the engine can settle into a relaxed state, covering ground with minimal fuel consumption. This reveals the versatility of the powertrain, offering decent fuel economy in everyday driving, while still providing exhilarating performance when desired.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 BMW 540i xDrive Sedan is estimated at $2,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is an estimate, and your actual fuel costs will depend on your driving habits, the type of fuel you use, and local fuel prices. The EPA doesn’t specify which fuel grade is used in their calculations, but premium fuel is recommended for optimal performance in the 540i’s turbocharged engine.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy may vary. Aggressive driving, frequent short trips, and carrying heavy loads will all negatively impact MPG. Prioritizing smooth acceleration, maintaining consistent speeds on the highway, and minimizing idling can help you get closer to the EPA figures. Owners who spend most of their time in congested urban environments will likely see numbers closer to the city estimate, while those who primarily drive on open highways can expect figures closer to the highway rating. Many BMW enthusiasts will check 540I MPG across all years to get a sense of the vehicle’s typical performance.

How it compares

The 2024 BMW 540i xDrive competes in a segment filled with alternatives. The Mercedes-Benz E450 4MATIC, powered by a turbocharged inline-six, achieves a similar 24 MPG combined. This makes it a direct competitor in terms of both performance and fuel consumption. The Audi A6 55 TFSI, also featuring a turbocharged V6, manages 25 MPG combined, a slight disadvantage against the BMW. However, the Lexus ES 350, with its naturally aspirated V6, boasts a combined 26 MPG, edging closer to the 540i xDrive. These comparisons are important because buyers in this class desire a degree of practicality and cost-effectiveness, as well as performance. If you are interested, see all Bmw fuel economy data.

Tips to maximize efficiency

Use the selectable driving modes. The 540i xDrive typically offers “Eco Pro” or “Comfort” modes, which optimize engine and transmission settings for fuel efficiency. These modes reduce throttle response and encourage earlier upshifts, helping you save fuel without sacrificing too much performance.

Monitor your tire pressure diligently. Properly inflated tires reduce rolling resistance, which translates to improved fuel economy. Check your tire pressure regularly and inflate them to the recommended level indicated on the doorjamb sticker. It’s an easy way to make a small but noticeable difference.

Avoid unnecessary idling. Modern engines are designed to be efficient at startup, so idling for extended periods consumes fuel without helping you move. If you anticipate being stationary for more than a minute, turn off the engine.

Practice smooth and progressive acceleration. Avoid sudden bursts of speed, as aggressive acceleration consumes significantly more fuel. Accelerate gradually and maintain a consistent speed whenever possible.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which optimizes fuel efficiency. It also reduces the subconscious tendency to speed up and slow down, further improving MPG.
