19 MPG combined isn’t going to win the 2016 BMW Z4 sDrive35is any fuel efficiency awards, but most drivers of this roadster are willing to make that trade-off. This isn’t a practical commuter car; it’s a performance machine designed to deliver driving thrills first and foremost. The Z4 buyer seeks open-air excitement and the intoxicating rush of a turbocharged inline-six, which increases fuel consumption.

City and highway performance

The EPA estimates the 2016 Z4 sDrive35is at 17 MPG in the city and 23 MPG on the highway. These figures reflect the vehicle’s focus: spirited acceleration and dynamic handling. The turbocharger is always ready to deliver a surge of power, and the seven-speed dual-clutch automatic transmission encourages aggressive driving with its rapid shifts. While you could drive it gently to achieve the EPA numbers, that’s simply not what this car is designed for. Expect to see a figure closer to the city MPG in mixed driving, especially if you frequently use the BMW’s performance potential.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW Z4 sDrive35is at $3,050. This calculation is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which this engine requires. The higher running cost is part of the ownership experience for a performance roadster like this. If you’re primarily concerned with fuel economy, there are far more suitable vehicles. The Z4 buyer prioritizes driving pleasure, and accepts the fuel bill as a necessary expense.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the 2016 Z4 sDrive35is often deviates based on driving style, traffic conditions, and even the type of roads you frequent. Aggressive acceleration, frequent use of the manual shift mode, and stop-and-go traffic will all negatively impact fuel consumption. Conversely, consistent highway cruising at moderate speeds will likely yield results closer to, or even slightly above, the EPA’s estimate. Ultimately, your mileage will vary, and it’s up to you to balance performance with efficiency.

How it compares

Compared to other roadsters, the 2016 Z4 sDrive35is lags behind some of its competitors in fuel economy. For example, the Porsche 718 Boxster, even in its S trim, achieves significantly better mileage (22 MPG combined). The Audi TTS Roadster also offers better fuel efficiency (25 MPG combined) while still providing a sporty driving experience. Even the previous-generation (2015) Mercedes-Benz SLK350 manages around 24 MPG combined, edging out the Z4. The Z4 stands out with its distinct inline-six turbo engine, but the fuel cost will be higher. Knowing all Bmw fuel economy data can help put the Z4’s consumption into perspective with other vehicles in the lineup.

Tips to maximize efficiency

Adopt a smoother driving style. Avoid harsh acceleration and braking; anticipate traffic flow to maintain a consistent speed. The Z4’s engine responds well to gentle inputs, and you can still enjoy the performance without constantly pushing it to its limits.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, leading to reduced fuel economy. Check your tire pressure regularly and inflate them to the recommended level, found on the doorjamb. These small adjustments can lead to improvements.

Minimize idling. Letting your engine idle for extended periods wastes fuel. If you’re stopped for more than a minute, turn off the engine. Restarting the engine consumes less fuel than idling for a prolonged time, particularly with modern engine management systems.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can significantly improve fuel economy on long highway journeys. Avoid unnecessary acceleration and deceleration, allowing the system to manage the throttle for optimal efficiency. Also you can discover the Z4 MPG across all years and compare the figures.

Consider using a lighter weight oil. Switching to a synthetic oil with a lower viscosity, such as 0W-30, can reduce internal engine friction and improve fuel economy slightly. Consult your owner’s manual or a qualified mechanic to ensure the oil is compatible with your engine.
