124 MPG combined shows the efficiency of the 2016 BMW i3 BEV. This isn’t a “compliance car” reluctantly foisted upon the buying public. It’s a deliberately unconventional EV designed for urban drivers who prioritize efficiency, sustainability, and a distinctive aesthetic. The i3’s radical design, carbon fiber reinforced plastic (CFRP) construction, and focus on maximizing electric range make it stand out in a world of increasingly similar vehicles.

City and highway performance

The EPA estimates 137 MPG in the city and 111 MPG on the highway for the 2016 i3 BEV. This difference reflects the i3’s design strengths. In stop-and-go city driving, regenerative braking captures kinetic energy, feeding it back into the battery and significantly extending range. This is where the i3 shines, making it ideal for commutes and errands within a metropolitan area where the car is frequently slowing down. Highway driving, which involves sustained speeds and less reliance on regenerative braking, results in a lower, but still impressive, fuel economy rating. These figures make sense when considering the typical buyer, someone who lives in an urban area and wants a small efficient car.

Annual fuel cost

The EPA estimates the 2016 BMW i3 BEV’s annual fuel cost at exactly $600. This figure is based on driving 15,000 miles per year, with a percentage split between city and highway driving, and using the national average electricity costs at the time of calculation. Of course, the actual cost will vary depending on individual driving habits, local electricity rates, and whether the owner has access to off-peak charging or solar power. But $600 a year is an exceptionally low annual “fuel” bill, and a primary reason for choosing the i3. You can view all Bmw fuel economy data on our site.

Real-world expectations

While the EPA estimates are a useful benchmark, real-world experiences can vary. The i3’s range is affected by factors such as ambient temperature, driving style, and the use of climate control. Aggressive acceleration and high speeds deplete the battery faster, as does running the air conditioning or heater at full blast. Drivers who prioritize efficiency can often exceed the EPA estimates, particularly in city driving.

How it compares

Compared to other electric vehicles of its time, the 2016 i3 BEV held its own in terms of efficiency. For example, the 2016 Nissan Leaf achieved around 114 MPGe combined, while a 2016 Ford Focus Electric hovered around 107 MPGe combined. The i3 distinguished itself with its premium feel and distinctive design. Buyers accepted range compromises in exchange for the luxury and innovative approach that BMW offered. Those looking at the i3 would likely also consider the Chevrolet Bolt that arrived the following year, but the Bolt was not available in 2016, and some preferred the smaller size and maneuverability of the i3 for true urban use.

Tips to maximize efficiency

Take advantage of the i3’s regenerative braking. By anticipating traffic and lifting off the accelerator early, you can maximize energy capture and extend your range. Learn how the different drive modes, such as Eco Pro and Comfort, impact energy use and how to use them effectively. Eco Pro prioritizes efficiency by reducing accelerator sensitivity and limiting climate control output.

Precondition the cabin while the i3 is still plugged in. This heats or cools the interior using grid power, rather than draining the battery. This extends range, especially in colder climates where battery performance is naturally reduced. Set a timer on the car’s infotainment system, or through the BMW Connected app, to precondition the cabin shortly before departure.

Minimize aerodynamic drag. Remove unnecessary items from the car’s roof or cargo area. Keep tires properly inflated to the recommended pressure. Low tire pressure increases rolling resistance, which reduces efficiency and can degrade handling, and is especially relevant in the i3’s unique tire setup.

Consider using the i3’s navigation system even for familiar routes. It provides range estimates based on current traffic conditions and elevation changes, allowing you to optimize your route for efficiency. Adaptive Cruise Control can also help, particularly on flowing freeways.
