19 MPG combined won’t win any fuel efficiency awards, but for the 2019 BMW M4 Convertible Competition, it’s almost beside the point. This is a high-performance, open-air driving experience powered by a boosted inline-six, and drivers who buy this car generally prioritize exhilarating acceleration and sharp handling over minimizing trips to the gas station. To be overly concerned about saving every last mile from each gallon would be to misunderstand the M4’s purpose.

City and highway performance

Breaking down that 19 MPG combined figure, the M4 Convertible Competition achieves an estimated 16 MPG in the city and 22 MPG on the highway. The lower city MPG is not surprising, given the stop-and-go nature of urban environments that constantly tax the engine. The M4’s responsive throttle and eagerness to accelerate contribute to this figure, tempting drivers to push harder than they might in a more economical vehicle. On the open road, the 22 MPG highway rating is achievable with mindful driving, but the M4’s inherent athleticism makes restraint challenging. The car begs to be driven, and driven hard and that behavior is rarely conducive to maximizing economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 BMW M4 Convertible Competition at $3,050. This calculation is based on driving 15,000 miles per year, current national average fuel prices, and a mixture of 55% city and 45% highway driving. Individual costs will vary depending on driving habits and local fuel prices, but this figure provides a benchmark for potential owners to consider. This also assumes premium fuel, which is mandatory for this engine. Using lower-octane gasoline would be detrimental to performance and could even damage the engine.

Real-world expectations

While the EPA figures provide a useful baseline, real-world fuel economy can vary significantly depending on driving style, traffic conditions, and even weather. Drivers who frequently explore the M4’s performance will likely see figures lower than the official estimates. However, drivers who prioritize fuel efficiency and adopt a more conservative driving style might be able to match or even slightly exceed the EPA numbers. Most M4 Convertible Competition owners aren’t buying the car to save gas, they’re buying it for the thrill of the drive, and that impacts fuel consumption.

How it compares

Compared to its performance-oriented competitors, the M4 Convertible sits in a similar range. The Mercedes-AMG C63 S Convertible, with its powerful V8 engine, achieves an EPA-estimated 17 MPG combined. The Porsche 911 Carrera Cabriolet manages around 20 MPG combined, while the Audi RS5 Cabriolet lands in a similar ballpark at 19 MPG combined. Therefore, someone cross-shopping these cars will quickly realize that saving gas isn’t really a priority.

Looking at M4 MPG across all years, you find that similar models across several model years have very close EPA ratings. This isn’t unexpected for a vehicle that has retained the same basic powerplant and core mission. If you’re interested in seeing all Bmw fuel economy data, you can explore available options.

Tips to maximize efficiency

While the M4 Convertible Competition isn’t designed for maximum fuel economy, there are a few strategies drivers can use to get a bit more range out of each tank. First, avoid aggressive acceleration and braking. The M4’s powerful engine responds instantly to throttle inputs, but a gentler touch at the start of acceleration will result in noticeably better fuel consumption.

Second, use the car’s driving modes. Selecting the “Eco Pro” mode will remap the throttle response and adjust other parameters to prioritize fuel efficiency. This mode won’t transform the M4 into a Prius, but it can make a difference in everyday driving, especially in stop-and-go traffic.

Also, ensure that the tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check the tire pressure regularly and maintain the recommended levels specified in the owner’s manual. This will also improve handling and tire wear.

Finally, consider shedding unnecessary weight. Carrying extra cargo in the trunk adds to the vehicle’s overall weight, which reduces fuel efficiency. Remove any unnecessary items from the car to minimize weight and improve fuel economy. Even a few pounds can make a small difference over time.
