Achieving 80 MPG combined, the 2023 BMW i4 M50 Gran Coupe with the optional 20-inch wheels achieves strong fuel economy, especially considering its high level of performance. This isn’t a Prius competitor; it’s a performance-oriented Gran Coupe with a focus on spirited driving, and the efficiency it offers is a pleasant bonus. The i4 M50 is designed for buyers who want the thrill of a high-performance BMW, the practicality of a four-door hatchback (though BMW calls it a coupe), and the lower fuel costs of an electric vehicle.

City and highway performance

The EPA numbers show a slight variation between city and highway driving. The i4 M50 delivers 79 MPG in city driving and 80 MPG on the highway. These two figures are so close that drivers won’t notice any significant difference in efficiency whether they’re navigating urban streets or cruising at highway speeds. Electric vehicles generally score higher in the city than on the highway. The i4 M50 delivers impressively consistent results across both environments, likely due to the aerodynamic optimization and efficient power management of the vehicle’s powertrain.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW i4 M50 Gran Coupe (20-inch wheels) at $950. This figure is based on driving 15,000 miles per year, combined with the national average cost of electricity. This is a hypothetical number, because the actual fuel cost will depend on how much you drive and the cost of electricity specific to your location and charging habits. Charging at home when rates are low will further decrease the expenses. Nonetheless, $950 per year is a significant selling point for potential buyers.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy can vary based on several factors. Driving style, weather conditions, and terrain can all impact efficiency. Aggressive acceleration and frequent hard braking will decrease fuel economy. Colder temperatures can also reduce battery performance, impacting your range. Conversely, driving in ideal conditions and using regenerative braking effectively can help you achieve, or even exceed the EPA estimates. If you use sports mode often, expect slight real-world differences.

How it compares

The i4 M50 competes in a space with other high-performance electric vehicles. The Tesla Model 3 Performance, another popular choice, achieves 113 MPGe combined. Audi’s e-tron GT, while also delivering strong performance, achieves 82 MPGe combined. While some competitors may offer slightly better efficiency, the i4 M50 distinguishes itself with its driving dynamics, BMW heritage, and Gran Coupe styling. The Polestar 2 Dual Motor offers 107 MPGe combined. All Bmw fuel economy data gives you additional context. What these comparisons underscore is that buyers in this segment want performance with reasonable running costs. See I4 MPG across all years for alternative versions.

Tips to maximize efficiency

Take full advantage of regenerative braking. The i4 M50 offers adjustable regenerative braking settings. Experiment with different levels to find what works best for your driving style. In higher settings, the car will aggressively slow down when you lift off the accelerator, channeling that kinetic energy back into the battery.

Precondition the battery before driving, especially in cold weather. Use the BMW app to preheat or precool the cabin while the car is plugged in. This will draw power from the grid rather than the battery, preserving range and optimizing battery performance when you hit the road.

Minimize use of accessories that draw significant power. Features like heated seats, heated steering wheel, and climate control can all impact range. Use them judiciously, opting for them only when needed to maximize efficiency.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly, especially during colder weather, and ensure they are inflated to the recommended pressure that is listed on the door jamb.

Drive smoothly and avoid aggressive acceleration. Electric vehicles deliver instant torque, making it tempting to accelerate quickly. However, gentle and consistent acceleration will help to conserve energy and extend your range. Smooth, consistent speed also makes passengers feel more comfortable.
