23 MPG combined won’t win any hypermiling competitions, but in the world of mid-size luxury SUVs, the 2023 BMW X5 sDrive40i occupies a reasonable middle ground. This vehicle prioritizes a refined driving experience, ample space, and advanced technology over outright fuel efficiency. Buyers are typically successful professionals or families who value performance and luxury, and for them, the MPG figure is a manageable compromise.

City and highway performance

The X5 sDrive40i earns its EPA estimates with a split of 21 MPG in the city and 26 MPG on the highway. That city figure reflects the frequent stop-and-go driving that many X5 owners experience during their daily commutes. The 3.0L inline-six responds quickly thanks to its turbocharger but requires frequent applications of the accelerator, which impacts fuel consumption. On the open road, the X5 settles into a quiet cruise aided by the smooth-shifting 8-speed automatic transmission. The engine operates in its efficiency sweet spot, and those highway miles help preserve fuel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW X5 sDrive40i at $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Actual fuel costs can vary significantly depending on individual driving habits, local fuel prices, and the type of fuel used. While the sDrive40i doesn’t require premium fuel, using it can sometimes improve performance and potentially fuel economy, though the cost-benefit needs consideration. Expect to see proportional changes in your yearly fuel expenditure for those who drive significantly more or less than 15,000 miles annually.

Real-world expectations

EPA estimates provide a baseline, and real-world fuel economy can vary. X5 drivers who accelerate quickly or frequently drive in congested urban environments can expect to see MPG figures closer to the city estimate, maybe even slightly lower. However, those who prioritize highway driving and practice fuel-efficient driving techniques may be able to achieve or even surpass the EPA’s highway estimate.

The X5’s driving mode selector allows drivers to choose between different settings, including an “Eco Pro” mode designed to maximize fuel efficiency by adjusting throttle response and transmission behavior, hopefully coming closer to what you see by browsing all Bmw fuel economy data.

How it compares

The X5 sDrive40i’s fuel economy positions it competitively within its segment. The Acura MDX, for example, achieves around 22 MPG combined with its standard V6 engine. The Mercedes-Benz GLE 350, another key competitor, hovers around 22 MPG combined as well. The Volvo XC90 B5, with its turbocharged and supercharged four-cylinder, manages around 25 MPG combined, but some buyers find its engine less refined than the BMW’s inline-six. Selecting a hybrid X5, the xDrive45e, gives considerably better fuel economy, but at a higher price and it requires charging. The X5 buyer is often willing to accept slightly lower MPG than some competitors in exchange for the superior driving dynamics and prestige associated with the BMW brand. Research X5 MPG across all years.

Tips to maximize efficiency

Engage “Eco Pro” mode whenever possible, especially during city driving or on relatively flat highway stretches. Eco Pro softens the throttle response, encourages earlier upshifts, and optimizes climate control settings for increased fuel economy to squeeze out a bit more MPG.

Maintain a steady speed on the highway, avoiding excessive acceleration and braking. Use cruise control whenever appropriate to minimize speed fluctuations. The X5’s adaptive cruise control system can also help maintain a safe following distance and improve efficiency.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level, often found on a sticker inside the driver’s side doorjamb.

Reduce excess weight in the vehicle. Carrying unnecessary cargo adds to the vehicle’s overall weight, which increases fuel consumption. Remove any items that are not essential for your trip.

Minimize idling. Avoid letting the engine idle for extended periods, such as at long traffic lights or when waiting for someone. If you anticipate a delay of more than a minute, turn off the engine. Modern cars can quickly and easily be restarted without doing harm to the engine.
