The 2023 BMW i4 eDrive40 Gran Coupe, when equipped with 19-inch wheels, achieves an EPA-estimated 99 MPG combined. This high number isn’t just about saving fuel, it’s about performance without the guilt in a sporty design. The i4 eDrive40 appeals to buyers who want the responsiveness and smooth power delivery of an electric drivetrain in a stylish BMW. For them, the high MPGe is a critical component of the modern experience they seek.

City and highway performance

The advantage of an electric vehicle is its consistent efficiency across different driving conditions, and the i4 eDrive40 performs well. The EPA rates it at 100 MPGe in the city and 98 MPGe on the highway, showing only a small drop as speeds increase. This similar performance is due to the electric motor’s instant torque and efficient energy recuperation during braking, especially useful in stop-and-go traffic. The automatic transmission, a single-speed unit, supports the smooth and efficient power delivery. Electric motors are more efficient at converting energy into motion, especially at lower speeds, resulting in the higher city rating.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW i4 eDrive40 Gran Coupe (19-inch wheels) at $750. This is based on driving 15,000 miles per year and using national average electricity prices. This results in very low running costs, especially compared to gasoline-powered luxury vehicles of similar size. The $750 calculation shows the financial benefits of electric vehicle ownership.

Real-world expectations

While the EPA estimates are a helpful guide, real-world MPGe can vary based on driving habits. How you drive is important: fast acceleration and hard braking will drain the battery faster. Air temperature also affects performance because cold weather can reduce battery performance. Even with these factors, the I4 performs well, and some owners report achieving numbers close to the EPA estimates in mixed driving conditions. Intelligent energy management systems and driver selectable modes help efficient operation.

How it compares

The Audi e-tron GT, an electric four-door coupe with a similar style and position, achieves an EPA combined rating of 82 MPGe. A Tesla Model 3 Long Range gets 132 MPGe. These comparisons matter for the i4 buyer. The Tesla focuses on maximum efficiency and range, while the Audi emphasizes luxury and performance feel at the expense of MPGe. The I4 balances efficiency with BMW’s driving dynamics and interior.

Tips to maximize efficiency

Use the I4’s regenerative braking system. By predicting traffic and gradually lifting off the accelerator, you can recapture energy and extend your range without affecting how you drive. Select the “B” driving mode to maximize regenerative braking.

Precondition the battery before driving. By heating or cooling the battery while the car is plugged in, you optimize its temperature and increase efficiency, especially in extreme weather. This lowers energy demand once you start driving.

Avoid accelerating too fast. While the i4’s instant torque is fun, bursts of acceleration consume energy. Consistent driving will improve MPGe.

Check tire pressure. Keeping the correct tire pressure, as shown on the doorjamb sticker, reduces rolling resistance and increases efficiency. Low tire pressure hurts fuel economy.

Consider using Eco Pro mode for everyday driving. This mode adjusts vehicle settings, such as throttle response and climate control, to focus on energy conservation. It’s an easy way to increase overall efficiency without changing your driving style.
