26 MPG combined isn’t going to win any fuel economy awards, but for the 2016 BMW Z4 sDrive28i, it’s almost beside the point. This isn’t a vehicle purchased for hypermiling; it’s a two-seat roadster designed for spirited driving and open-air enjoyment. The Z4 buyer prioritizes the thrill of the drive over pinching pennies at the pump. They’re buying a statement, a feeling, not simply transportation.

City and highway performance

The EPA estimates for the Z4 sDrive28i break down to 22 MPG in the city and 32 MPG on the highway. The city figure is predictably lower due to stop-and-go traffic and the engine’s tendency to stay in lower gears. The highway number is more respectable, reflecting the efficiency of the turbocharged 2.0-liter engine and the smooth-shifting 8-speed automatic transmission when cruising. These numbers are directly influenced by throttle inputs, and a heavy foot will invariably lead to lower mileage.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW Z4 sDrive28i at $2,250. This figure is based on driving 15,000 miles per year and uses the national average fuel price at the time of calculation. Obviously, this number will fluctuate based on current gas prices and individual driving habits. Someone who drives predominantly in the city or has a lead foot will likely exceed this estimate, while those who primarily use the Z4 for longer highway trips and practice smoother driving techniques could potentially spend less.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy often varies. Drivers should expect to see numbers within a reasonable range of the official ratings, say 2-3 MPG either way. Factors such as driving style, traffic conditions, tire pressure, and even the use of air conditioning can all influence fuel consumption. Keeping up with scheduled maintenance, particularly air filter replacements and spark plug changes, can also help maintain optimal fuel efficiency.

How it compares

Compared to other sporty roadsters and convertibles of its vintage, the Z4’s fuel economy is generally competitive. For example, the 2016 Mazda MX-5 Miata with its 2.0-liter engine achieves around 30 MPG combined with the automatic transmission, making it noticeably more fuel-efficient. Conversely, a more powerful option like the 2016 Porsche Boxster, while offering greater performance, returns around 25 MPG combined. Other convertible models like the Audi A3 Cabriolet offer similar MPG but with less driving enjoyment. Review all Bmw fuel economy data to see how it compares to the competition within the brand.

Tips to maximize efficiency

Take advantage of the Z4’s driving modes. The “Eco Pro” mode optimizes throttle response and shift points for maximum fuel efficiency, particularly in city driving. While it might slightly dampen the car’s sporty character, it can make a noticeable difference in MPG, especially on shorter trips.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels found on the doorjamb sticker. This simple step can have a surprisingly positive impact on fuel economy.

You should also perform regular maintenance as mentioned when reviewing Z4 MPG across all years.

Avoid aggressive acceleration and braking. Smooth, gradual inputs are key to maximizing fuel efficiency. Anticipate traffic flow and avoid unnecessary hard braking. Gentle acceleration from a stop also helps to minimize fuel consumption. The Z4 is a quick car, but that doesn’t mean using all of its power all the time.

Reduce unnecessary weight. Carrying extra weight in the trunk or passenger compartment puts additional strain on the engine. Remove any unnecessary items to lighten the load and improve fuel economy. Even a few pounds can make a difference over time.
