With a combined 104 MPG, the 2025 BMW i4 eDrive40 Gran Coupe (on 19-inch wheels) is a very efficient vehicle, especially given its performance and luxury features. It’s a stylish, driver-focused Gran Coupe that uses electricity instead of gasoline. The i4 eDrive40 appeals to buyers who want a sporty and luxurious experience, and also desire the lower fuel costs and financial benefits of an electric powertrain. They are willing to pay a premium for the BMW brand and its associated driving dynamics.

City and highway performance

The EPA estimates the i4 eDrive40 will get 106 MPG in the city and 103 MPG on the highway. These figures show how efficient electric powertrains are. They do well in stop-and-go conditions because they use regenerative braking. The slight drop in highway MPG is normal for EVs, as they don’t have cylinder deactivation or tall gearing like gasoline cars. The high city MPG is great for city drivers who might otherwise have poor efficiency in a gas-powered car. It minimizes wasted energy during constant acceleration and deceleration. For those who commute or live in the city, the i4’s efficiency is a clear plus.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2025 BMW i4 eDrive40 Gran Coupe with 19-inch wheels is $750. This is based on driving 15,000 miles per year and using the national average electricity price. That’s appealing for drivers used to paying much more for gasoline. Of course, the exact cost will vary based on local electricity rates and driving habits. But even with higher prices or lots of highway driving, it’s likely to be cheaper than fueling a similar gasoline vehicle. This calculation really shows how much money you could save by driving an electric vehicle.

Real-world expectations

While the EPA estimates are a good starting point, real-world range and MPGe can change based on several things. Driving style is a big factor; fast acceleration and high speeds will lower efficiency. Weather also affects EV range; cold temperatures can cut battery performance. Using climate control and heated seats also needs energy and cuts total range. It’s good to expect slightly less, especially in winter. But even with these things, the i4 eDrive40 will likely have good real-world efficiency for most drivers. Be sure to look at I4 MPG across all years to get a sense of real-world variations.

How it compares

The BMW i4 eDrive40 compares well to other luxury electric vehicles. The Tesla Model 3 Long Range, for example, gets an estimated 134 MPGe combined, giving it a better efficiency rating. However, it lacks the premium feel and brand cachet that many BMW buyers want. The Polestar 2 Long Range Dual Motor gets around 107 MPGe, making it a closer competitor, but it doesn’t have the same distinctive styling and driving dynamics as the i4. The Audi e-tron GT, while very stylish, gets 82 MPGe combined; it focuses on performance more than efficiency. This comparison shows how the i4 eDrive40 balances luxury, performance, and efficiency, offering a nice middle ground for many buyers. You can find all Bmw fuel economy data to compare across the full model range.

Tips to maximize efficiency

One simple way to improve efficiency in the i4 eDrive40 is to effectively use its regenerative braking system. Anticipate stops and coast when you can, letting the car recover energy and extend your range. Avoid quick acceleration, as this drains the battery fast. Smooth and consistent driving helps efficiency and range.

Preconditioning the cabin while the car is plugged in can reduce energy use while driving. Warming or cooling the interior before you unplug means the car doesn’t need to draw as much power from the battery once you’re driving. This is effective in cold weather and helps reduce energy consumption.

Proper tire inflation is important for fuel efficiency. Check your tire pressure often and make sure they are at the recommended level. Underinflated tires increase rolling resistance, which cuts efficiency. Adhering to the recommended tire pressure is a quick and easy way to ensure optimal range.

Reduce weight in the car. Extra items in the trunk or back seats add to the vehicle’s load and cut efficiency. Remove items you don’t need to carry regularly to minimize drag and help stretch your battery range.

Use the available driving modes. The i4 eDrive40 often has an “Eco Pro” mode which favors efficiency over performance. This mode limits power output and adjusts vehicle settings to maximize range. It’s a good option for daily commutes.
