The 2016 BMW Z4 sDrive35i gets 19 MPG combined. It’s a sharply focused roadster designed to deliver a visceral driving experience. Fuel economy is less important than the thrill of the turbocharged inline-six and the open-air freedom it provides. Buyers in this segment prioritize performance and style over thrift, understanding that smiles per gallon are a more relevant metric than miles per gallon.

City and highway performance

The EPA estimates for the 2016 Z4 sDrive35i with the automatic transmission are 17 MPG in the city and 23 MPG on the highway. The city figure reflects the stop-and-go conditions where the engine’s turbo lag can be more pronounced, and the automatic transmission spends more time shifting. On the open road, the highway number suggests reasonable efficiency, achievable when cruising at a consistent speed. However, the Z4’s playful nature often encourages drivers to tap into the engine’s considerable power, potentially resulting in real-world highway figures that may fall short of the EPA estimates.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2016 BMW Z4 sDrive35i to be exactly $3,050. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving patterns, and assuming the national average fuel price. It’s a useful benchmark for comparing the Z4’s running costs to other vehicles, but individual expenses will vary depending on driving habits, location, and fuel prices.

Real-world expectations

While the EPA provides a standardized measure, real-world fuel economy can differ significantly. Drivers who frequently exploit the Z4’s performance potential, using spirited acceleration and aggressive driving maneuvers, will likely see their average MPG fall considerably below the official ratings. Conversely, those who prioritize smooth, consistent driving and adhere to speed limits may achieve figures closer to the EPA estimates. The Z4’s relatively small fuel tank (14.5 gallons) also means fuel stops could be more frequent than with larger, more fuel-efficient vehicles.

How it compares

Compared to other sporty convertibles of its era, the 2016 Z4’s fuel economy is neither exceptional nor abysmal. For example, the Porsche Boxster (981 generation) equipped with the PDK automatic transmission achieved a slightly better 22 MPG combined, while offering comparable performance. The Mercedes-Benz SLK350, with its V6 engine, landed around 23 MPG combined. However, the BMW buyer is often drawn to its specific combination of German engineering, driver-focused dynamics, and iconic styling, making fuel economy a smaller factor in the purchase decision.

Tips to maximize efficiency

Avoid aggressive acceleration. The Z4’s turbocharger responds instantly to throttle input, but applying full throttle frequently will significantly reduce fuel economy. Gradual acceleration and smooth transitions between gears will help conserve fuel and prevent the engine from working harder than necessary.

Maintain a consistent speed on the highway. Using cruise control whenever possible will help you avoid unnecessary speed fluctuations, which can negatively impact fuel efficiency. Resist the temptation to constantly overtake other vehicles or engage in high-speed bursts, as these maneuvers consume extra fuel.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tires regularly and maintain the recommended pressure outlined on the sticker inside the driver’s side doorjamb.

Reduce unnecessary weight. Carrying extra items in the trunk or cabin adds weight to the vehicle, which increases fuel consumption. Remove any unnecessary items to lighten the load and improve fuel economy.
