Expert Quotes:

22 mpg city, 33 highway (sDrive28i, automatic); 22/24 mpg (sDrive28i, manual) 19/26 mpg (sDrive35i, manual); 17/24 mpg (sDrive35i and sDrive35is, DCT)

Despite the power increase, the 35is is no thirstier for premium fuel than the regular 35i with DCT
Motor Trend

From fast to efficient, the BMW Z4's engine range offers more choice than most roadsters for those concerned about gas mileage.

The base Z4 sDrive28is uses a turbocharged four-cylinder engine to score 22 mpg city, 34 mpg highway, and 26 mpg combined with the manual transmission. Opting for the eight-speed auto shaves 1 mpg from the highway rating, but leaves the others untouched.

With more power comes somewhat poorer gas mileage: the sDrive35i rates 19/26/21 mpg city/highway/combined with the manual transmission. Pick the dual-clutch seven-speed gearbox and those numbers fall to 17/24/20 mpg.

The sportiest model, the Z4 sDrive35is, also scores 17/24/20 mpg city/highway/combined.

Those looking to save some cash at the pump with their sport roadster will choose the turbo four-cylinder Z4 sDrive28i, and in our experience, real-world gas mileage easily matches, and occasionally exceeds, the EPA ratings.


In four-cylinder turbo form, the BMW Z4 is among the most efficient sports cars.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
