The 2022 BMW i4 eDrive40 Gran Coupe with 18-inch wheels has an official EPA rating of 109 MPG combined, a figure possible only with an all-electric vehicle. This focuses on the efficiency of converting electrical energy into movement, a key selling point for buyers who want luxury, performance, and zero tailpipe emissions.

City and highway performance

The i4 eDrive40 provides consistent efficiency in both city and highway driving, with an EPA rating of 109 MPG in the city and 108 MPG on the highway. This consistency shows the electric motor’s efficiency and a well-tuned energy management system. Gasoline engines often see fuel economy decrease in stop-and-go traffic, but the i4 benefits from regenerative braking in city driving. This system captures kinetic energy during deceleration and converts it back into electricity, extending the car’s range. On the highway, efficiency remains high, but slightly lower than city driving because of the constant power to overcome wind resistance at higher speeds. Across all driving, the i4 eDrive40 minimizes energy consumption while providing engaging response.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW i4 eDrive40 Gran Coupe is $700. This is based on driving 15,000 miles per year and using national average electricity prices. For many buyers, this is a significant savings compared to traditional gasoline-powered cars, especially in the luxury segment. Electricity prices vary depending on location and time of use, but the i4 eDrive40’s efficiency ensures that running costs stay low, offering a financial incentive and the lower fuel costs of electric driving.

Real-world expectations

EPA ratings are a good benchmark, but real-world range and efficiency can vary depending on driving style, weather, and terrain. Quick acceleration, frequent climate control, and high speeds can reduce the i4 eDrive40’s range. In contrast, gentle acceleration, preconditioning the cabin while plugged in, and regenerative braking can maximize efficiency. Most owners report achieving range figures close to the official EPA estimate, showing the i4’s consistency in delivering its expected performance. Drivers who regularly travel long distances should consider charging times and the availability of charging stations when planning their journeys. Outside temperature can greatly impact the real world range.

How it compares

The 2022 BMW i4 eDrive40 Gran Coupe compares well to other electric vehicles in its class for efficiency. The Tesla Model 3 Long Range achieves an EPA-estimated 132 MPGe combined, but the i4 offers a premium interior and BMW driving dynamics. The Polestar 2 Long Range Dual Motor achieves 107 MPGe combined, very similar to all I4 MPG across all years. The Audi e-tron GT is rated at 82 MPGe combined, showing the i4’s superior energy efficiency. Buyers choose the i4 eDrive40 knowing it provides a balance between efficiency, performance, and luxury, appealing to drivers who prioritize a refined driving experience.

Tips to maximize efficiency

Precondition the cabin while the car is plugged in. Heating or cooling the interior from grid power before you unplug reduces the energy demand on the battery while driving, mainly in extreme temperatures. BMW lets you schedule preconditioning with the My BMW app, so you can have a comfortable cabin ready to go without sacrificing range.

Drive smoothly and watch traffic. Avoid quick acceleration and braking, as these actions consume more energy. Use the i4’s regenerative braking system by lifting off the accelerator early when approaching stops. You’ll preserve kinetic energy and put it back into your battery.

Optimize tire pressure. Correct tire pressure reduces rolling resistance, which improves efficiency. Check your tire pressure regularly and inflate them to the recommended level, found on the door jamb decal or in the owner’s manual. The correct pressure will optimize efficiency and handling.

Reduce aerodynamic drag. Remove unnecessary cargo from the roof or trunk that increases wind resistance. The i4 is designed with aerodynamic efficiency, so keeping the exterior clean and free of obstructions will help maintain its efficiency. The more aerodynamic the exterior the better, improving all BMW fuel economy data on the highway.

Use the ECO PRO driving mode. This mode optimizes vehicle settings, such as throttle response and climate control, to maximize efficiency. While it may slightly reduce performance, it can extend the i4’s range, especially during longer journeys. You can monitor the real-time energy consumption on the dashboard to learn about your driving habits and their impact on efficiency.
