23 MPG combined isn’t going to win any awards for efficiency, but for the 2019 BMW 440i xDrive Convertible, most owners readily accept it as part of the experience. This isn’t a commuter car designed for maximizing fuel savings; it’s a stylish, open-air grand tourer built for spirited driving and making a statement. Those priorities are more important than maximizing gas mileage.

City and highway performance

The EPA estimates that the 440i xDrive Convertible achieves 20 MPG in the city and 29 MPG on the highway. This difference reflects the engine’s characteristics and driving conditions. In stop-and-go city traffic, the 3.0L turbocharged inline-six engine consumes more fuel. The automatic transmission, even in its most efficient settings, cannot capitalize on the engine’s full potential.

On the open road, the story changes. With consistent speeds and less need for aggressive acceleration, the 440i excels. The smooth 8-speed automatic keeps the engine in its ideal range, allowing for respectable highway fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 BMW 440i xDrive Convertible at $2,500. This figure assumes 15,000 miles of driving per year, with a mix of city and highway driving. It also relies on the national average fuel prices at the time of the estimate. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. This figure gives a realistic indication of what owners can expect to budget annually for gasoline, assuming the vehicle will use premium gasoline, as recommended.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy for the 440i xDrive Convertible can vary. Drivers who accelerate quickly and frequently might see numbers closer to the lower end of the spectrum. But, those who prioritize smooth, consistent driving and use the car’s Eco Pro mode may be able to exceed the EPA estimates. Factors like weather conditions, tire pressure, and vehicle maintenance can also influence fuel consumption. Expect the 440i MPG across all years to shift depending on the care of the vehicle.

How it compares

In the world of luxury convertibles, the 440i’s fuel economy is average. The Audi S5 Cabriolet, with its turbocharged V6, delivers similar performance and luxury, but its fuel economy is nearly identical at 21 MPG combined. The Mercedes-Benz C43 AMG Cabriolet, with its more potent AMG-tuned engine, sacrifices some fuel efficiency, landing around 20 MPG combined. The Porsche 718 Boxster S, while offering a superior driving experience, achieves an EPA-estimated 22 MPG combined. For buyers looking at all Bmw fuel economy data, this places the 440i firmly in line with competitors in its segment. Ultimately, the decision values performance, luxury, and open-air enjoyment over saving gas.

Tips to maximize efficiency

The 440i xDrive Convertible offers various driving modes that can influence fuel consumption. Engage the Eco Pro mode for relaxed daily driving. It recalibrates the throttle response and shift points to prioritize efficiency. This mode can noticeably improve fuel economy, especially during longer commutes.

Avoid aggressive acceleration and sudden braking, as they significantly impact fuel consumption. Smooth, consistent driving is key to maximizing efficiency. Anticipate traffic flow and maintain a steady speed whenever possible. Treat the accelerator pedal gently, and the fuel gauge will stay higher longer.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, leading to reduced fuel economy. Check your tire pressures regularly and maintain the recommended levels. This small act of maintenance can significantly help fuel efficiency.

Reduce unnecessary weight in the vehicle. Carrying extra cargo puts more load on the engine, requiring more fuel to maintain performance. Before embarking on a journey, remove any items that are not essential. A lighter car is a more efficient car.

Service the car according to the manufacturer’s recommended maintenance schedule. A well-maintained engine operates more efficiently, ensuring optimal fuel consumption. Regular oil changes, air filter replacements, and spark plug inspections will contribute to both performance and fuel economy.
