The 2024 BMW i5 eDrive40 Sedan with 20-inch wheels achieves a combined 99 MPGe. This all-electric efficiency translates to very low running costs for a mid-size luxury sedan. The i5 prioritizes performance and technology, though, it isn’t built for economy-car frugality.

City and highway performance

The i5 eDrive40 shows consistent efficiency in both city and highway driving. The EPA estimates 99 MPGe in the city and 98 MPGe on the highway. This near-identical rating highlights the electric powertrain’s advantage in cities. Regenerative braking captures energy when decelerating, reducing energy consumption significantly. Highway driving remains efficient due to the i5’s aerodynamic design and optimized electric motor, which minimizes energy loss at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW i5 eDrive40 Sedan (20-inch Wheels) at $750. This is based on driving 15,000 miles per year, with a specified percentage split between city and highway driving, using the national average electricity cost. Individual electricity rates vary regionally and depending on charging habits, but the $750 figure gives a solid expectation for typical driving. These low running costs attract buyers who want long-term value, lower fuel costs, luxury, and performance.

Real-world expectations

EPA estimates provide a standardized benchmark. Real-world MPGe fluctuates based on driving style, ambient temperature, and accessory usage. Aggressive acceleration, frequent use of climate control, and extended high-speed cruising reduces efficiency.

Gentle driving, maximizing regenerative braking, and preconditioning the cabin while plugged in can improve upon the official figures. Drivers who understand electric vehicle efficiency can closely match or exceed the EPA’s estimates.

How it compares

The i5 eDrive40’s efficiency is competitive within the luxury electric sedan segment. The Tesla Model 3 Long Range, for example, gets an EPA-estimated 132 MPGe combined. The Cadillac LYRIQ RWD achieves 97 MPGe combined. The Model 3 leads in efficiency, but the i5 offers a distinct driving experience and a more traditional luxury car feel that appeals to a different kind of buyer. Those prioritizing BMW’s signature handling and interior refinement might accept the slight efficiency difference.

Comparing it to the gasoline-powered world, you would have to consider a Prius Prime (127 MPGe) to get significantly better “fuel” economy. The I5 MPG across all years is BMW’s commitment to efficient luxury.

Tips to maximize efficiency

Use regenerative braking. The i5 offers adjustable regenerative braking modes. Tailor the level of deceleration when lifting off the accelerator. Experiment with the settings to find the level that maximizes energy recapture without affecting driving comfort. This works well in stop-and-go traffic, which is common in cities.

Precondition the cabin. Use the BMW Connected app to preheat or precool the cabin while the car is plugged in. This reduces the energy load on the battery when you start driving, especially in extreme temperatures. Preconditioning improves efficiency on shorter trips.

Optimize tire pressure. Regularly check and maintain the recommended tire pressure for your i5. Underinflated tires increase rolling resistance, which reduces efficiency. Consult the sticker on the driver’s side doorjamb for the correct pressure, and remember that temperature changes affect tire pressure.

Adopt smooth driving habits. Avoid abrupt acceleration and hard braking, as these deplete the battery quickly. Anticipate traffic flow and maintain a consistent speed whenever possible. Smooth, gradual inputs optimize energy usage and extend your driving range. Think about it as surfing the wave of traffic, not fighting it.

Consider wheel size. This article discusses the 20-inch wheel option, but smaller wheel sizes generally offer better efficiency due to less weight and rolling resistance. If maximizing efficiency is important, consider the standard wheel option. Always compare all Bmw fuel economy data when choosing a model.
