The 2023 BMW i4 M50 Gran Coupe, when equipped with 19-inch wheels, gets a combined fuel economy equivalent of 96 MPG. This isn’t about achieving Prius-level thriftiness, it’s about delivering a high-performance driving experience with minimal compromise at the charging station. The i4 M50 appeals to drivers who crave the agility and responsiveness expected from a BMW M car, but who are also drawn to the benefits of electric power, instant torque, reduced emissions, and surprisingly good “fuel” economy.

City and highway performance

The i4 M50 excels in both city and highway driving, evidenced by its EPA ratings of 94 MPG in the city and 98 MPG on the highway. The city rating benefits from regenerative braking, which recovers energy during deceleration, turning the electric motors into generators and replenishing the battery pack. On the highway, the i4 M50’s aerodynamic efficiency keeps energy consumption in check, allowing for long-distance cruising with impressive efficiency, especially considering its performance. Don’t expect quite these numbers at sustained high speeds, but even aggressive driving will still deliver excellent results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW i4 M50 Gran Coupe (19-inch wheels) at $800. This is based on driving 15,000 miles per year and using national average electricity prices. Of course, your actual costs may vary depending on your driving habits, electricity rates in your area, and how frequently you charge at home versus public charging stations. Even with some variance, the $800 figure shows the potential for significant savings compared to a traditionally powered performance car.

Real-world expectations

While the EPA figures provide a useful benchmark, real-world fuel economy always depends on individual driving style and conditions. Drivers who frequently exploit the i4 M50’s full performance capabilities, including its launch control and Sport Boost function, will likely see a decrease in efficiency. Similarly, colder temperatures can negatively impact battery performance and range. However, even under less-than-ideal circumstances, the i4 M50 remains impressively efficient, especially when compared to other performance cars. Smart driving habits can help to maximize range and minimize charging costs.

How it compares

The i4 M50’s efficiency stands out in the performance EV segment. The Tesla Model 3 Performance, for example, achieves a combined EPA rating of 113 MPGe, making it slightly more efficient. However, the Polestar 2 Dual Motor with Performance Pack achieves an EPA rating of only 89 MPGe, highlighting the i4 M50’s strong performance in the performance EV category. Understanding all Bmw fuel economy data puts the i4 in a larger context, but the relevant comparisons are EVs that also aim to deliver on driver engagement. For those seeking a true driver’s EV, the i4 M50 offers a good balance of performance and efficiency, justifying a slightly lower number than its less enthusiast-oriented rivals. You can also compare the I4 MPG across all years to see how electric BMWs have evolved.

Tips to maximize efficiency

Take advantage of regenerative braking. The i4 M50 offers different levels of regenerative braking, including an “Adaptive” mode that automatically adjusts the level of regeneration based on traffic conditions. Experiment with these settings to find what works best for your driving style and maximize energy recovery, especially in stop-and-go traffic.

Precondition the battery. Before you start your drive, especially in cold weather, use the BMW Connected app to precondition the battery. This warms the battery to its optimal operating temperature, improving efficiency and range. Preconditioning while plugged in uses grid power, preventing battery drain and maximizing range.

Optimize your driving style. While the i4 M50 is designed for performance, smooth acceleration and consistent speeds will help to conserve energy. Avoid unnecessary hard acceleration and braking, and maintain a steady pace on the highway. Using cruise control can also help to improve efficiency on long drives.

Monitor your tire pressure. Properly inflated tires reduce rolling resistance, which improves fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure specified on the doorjamb sticker. This simple maintenance task can make a noticeable difference in efficiency.

Limit accessory use. Operating power-hungry accessories, such as the air conditioner or heated seats, can impact range, especially on shorter trips. Use these features carefully and consider pre-heating or pre-cooling the cabin while the car is plugged in to minimize battery drain.
