With 109 MPGe combined, the 2024 BMW i4 eDrive40 Gran Coupe (with 18-inch wheels) is one of the most efficient electric vehicles. More importantly, it shows BMW’s commitment to delivering a sporty driving experience while reducing emissions. This is about embracing a zero-emissions future while retaining the driving dynamics that BMW drivers expect. The typical i4 eDrive40 buyer appreciates premium aesthetics, advanced technology, and the instant torque and smooth acceleration of electric powertrains. They’re willing to invest in a vehicle that reflects their values, and the i4 delivers.

City and highway performance

The EPA’s city and highway ratings for the i4 eDrive40 are remarkably consistent: 109 MPGe in the city and 108 MPGe on the highway. This near-identical efficiency highlights the electric motor’s advantage, operating efficiently across a wide range of speeds and driving conditions. Electric motors don’t suffer from significant efficiency drops at lower speeds or during stop-and-go traffic, unlike gasoline engines. The i4’s regenerative braking system further enhances city efficiency by capturing kinetic energy during deceleration and converting it back into electricity, extending the vehicle’s range.

Highway driving remains efficient due to the i4’s aerodynamic design and the electric motor’s ability to maintain efficiency at cruising speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW i4 eDrive40 at $700. This is based on driving 15,000 miles per year and using the national average electricity price. This number significantly undercuts the fuel costs of similar gasoline-powered vehicles, even those with good fuel efficiency. While individual charging costs will vary depending on location, electricity rates, and charging habits (at-home vs. public charging), the $700 estimate provides a benchmark for understanding potential savings. Aggressive driving or frequent climate control use can impact this figure, but the low cost of electricity compared to gasoline makes the i4 a financially smart choice for many drivers.

Real-world expectations

EPA ratings provide a benchmark, but real-world MPGe can vary based on driving style, weather, and terrain. Aggressive acceleration, frequent climate control use, and high speeds will reduce the i4’s efficiency and range.

Cold weather can significantly impact battery performance. However, even under less-than-ideal conditions, the i4 eDrive40 is likely to deliver good efficiency, thanks to BMW’s energy management system and the electric motor’s efficiency. Drivers who prioritize smooth acceleration, minimize accessory usage, and use regenerative braking can expect results close to the EPA estimates.

How it compares

The i4 eDrive40 competes with a growing number of electric vehicles. The Tesla Model 3 Long Range, for example, has an EPA-estimated 131 MPGe combined, showcasing Tesla’s focus on efficiency. The Polestar 2 Long range Single motor comes in with 115MPGe combined. The Audi e-tron GT achieves 82 MPGe combined, showing that higher performance can come at the expense of efficiency. For an overview of all Bmw fuel economy data, the i4 stands out. The comparison isn’t simply about the highest MPGe number, the i4 appeals to buyers who prioritize the BMW driving experience, a luxurious interior, and a refined package, even if it means sacrificing some efficiency compared to EVs like Tesla.

Tips to maximize efficiency

Use regenerative braking to its fullest potential. The i4 offers customizable regenerative braking settings that allow drivers to adjust deceleration when lifting off the accelerator. Experiment with settings and find a level that anticipates traffic flow and maximizes energy recapture, minimizing brake pedal use.

Precondition the cabin while the vehicle is plugged in. Heating or cooling the interior while the i4 is connected to a charger draws power from the grid rather than the battery, preserving range. This is beneficial during extreme weather, ensuring battery performance from the start.

Adopt a smooth and consistent driving style. Avoid aggressive acceleration and abrupt braking, as these consume more energy. Gentle acceleration and maintaining a speed improve efficiency and extend range. Anticipate traffic patterns and maintain a safe following distance to minimize braking.

Properly inflate your tires to the recommended pressure. Underinflated tires increase rolling resistance, which reduces efficiency and range. Regularly check your tire pressure and maintain the level found on the doorjamb or in the owner’s manual.

Limit the use of energy-intensive accessories. The i4 offers comfort and convenience features, but excessive use of air conditioning, heating, and other electronic devices can impact efficiency. Use these features judiciously and prioritize efficient settings (e.g., using recirculated air for climate control) to minimize energy consumption.
