The 2021 Ford Mustang Mach-E RWD Extended achieves an EPA-estimated 97 MPGe combined. This efficient rating shows how well this electric crossover converts kilowatt-hours into forward motion, while keeping the iconic Mustang spirit alive.

City and highway performance

The EPA further breaks down the Mach-E RWD Extended’s efficiency, showing an impressive 104 MPGe in the city and 90 MPGe on the highway. The higher city rating reflects the benefits of regenerative braking, which recaptures energy during stop-and-go driving and converts kinetic energy back into battery power. On the highway, where aerodynamics and sustained speed are the main factors, the efficiency dips slightly, but it still remains incredibly high compared to any gasoline-powered vehicle (even hybrids) of similar size and performance. Drivers who spend most of their time navigating urban environments will see even greater gains in efficiency, while those with longer commutes will still benefit from the impressive electric range and lower running costs.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Ford Mustang Mach-E RWD Extended is just $800. This figure is based on driving 15,000 miles per year using a combination of city and highway driving, and assumes the national average electricity price. This highlights the significant cost savings compared to traditional gasoline vehicles. Many SUVs, even relatively efficient ones, can easily cost twice or even three times that amount to fuel annually. The $800 figure reflects the dramatic reduction in fuel expenses that comes with switching to electric power, and a major part of the Mach-E’s appeal for those seeking to minimize their running costs.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world MPGe can vary based on several factors, including driving style, weather conditions, and accessory use. Aggressive acceleration and sustained high speeds will decrease efficiency, just as they would in a gasoline car. Extreme temperatures can also impact battery performance, reducing range and MPGe. Preconditioning the battery, warming or cooling it while plugged in, can help mitigate these effects. Owners who prioritize smooth acceleration, anticipate traffic flow, and use regenerative braking effectively will likely see numbers close to, or even exceeding, the EPA estimates. The Mach-E’s trip computer provides detailed energy consumption data, drivers can understand their efficiency and optimize their driving habits.

How it compares

The 2021 Ford Mustang Mach-E RWD Extended competes directly with other electric crossovers like the Tesla Model Y Long Range (125 MPGe combined), the Hyundai Kona Electric (120 MPGe combined), and the Chevrolet Bolt EUV (115 MPGe combined). Although the Mach-E’s MPGe might not be the highest in the segment, it has good efficiency, performance, and style. A prospective buyer might choose the Mach-E over the Model Y because they prefer Ford’s more conventional interior design or its dealer network.

They might opt for it over the Kona Electric or Bolt EUV due to its larger size, better driving dynamics, and the Mustang name. Comparing all Ford fuel economy data across models reveals the clear efficiency advantage of the Mach-E over Ford’s gasoline-powered SUVs. This comparison is for those considering switching to electric power but wanting a familiar brand and driving experience. See MUSTANG MPG across all years for additional insights.

Tips to maximize efficiency

A smooth and gradual acceleration style is key to maximizing MPGe in the Mach-E. Avoid harsh acceleration and braking whenever possible. This conserves energy and reduces wear and tear on the tires and brakes.

Take advantage of the Mach-E’s regenerative braking features. Experiment with different regen modes to find the setting that best suits your driving style. One-Pedal Driving, which allows you to decelerate almost entirely by lifting off the accelerator, can significantly increase efficiency, especially in city driving.

Plan your routes strategically, considering traffic patterns and elevation changes. Avoiding congested areas and minimizing uphill climbs can help reduce energy consumption. Use the navigation system to identify charging stations along your route, allowing you to top up the battery if needed.

Precondition the battery before driving, especially in cold weather. This warms or cools the battery to its optimal operating temperature while the car is plugged in, reducing the energy needed to do so while driving. This simple step can improve range and MPGe.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, reducing efficiency. Check your tire pressure regularly and inflate them to the recommended level. Correct tire pressure improves MPGe, enhances handling and extends tire life.
