Testing the DC fast charging of the 2025 Ford Mustang Mach-E Rally

For the model year 2025, Ford updated the Mach-E in several areas. The main one was the addition of a heat pump to handle the climate duties in the cabin. For the Mach-E GT Premium, ventilated seats are on offer. But otherwise, the vehicle remains mostly unchanged from the bigger update in 2024.

The enjoyable Rally trim, a foul-weather friendly electric WRX, has a 91 kWh battery pack and has an EPA-rated 265 miles of range. It’s the weakest of the Mach-E variants for overall range, but that mostly comes down to the Rally’s wing, an additional one inch of ride height, and the Michelin CrossClimate aggressive all-season tires.

When it comes to how quickly it recharges, not much has changed. So we took it to a DC fast charger with just 2% state of charge remaining on the battery (an indicated 5 miles left of range), and charged it to 100%. We documented the entire process, and here’s what we found.

Total charging time

To go from 2% to 100% state of charge, the Mach-E Rally took us 89 minutes. That’s nearly an hour and a half on a charger, which is a bit on the longer side for vehicles we’ve tested. The car hit a peak DC fast charging rate of 157 kW. Interestingly, that peak number came before even a 10% state of charge. Most EVs charge the quickest between 10 and 80%. However, if someone only tested this car from those numbers, they likely wouldn’t have observed the peak rate.

We do set the location of the charger as a destination in the navigation system, so any preconditioning of the battery that happens automatically would occur. Usually at such a low state of charge, however, the car preserves energy for range and not for preconditioning.

The 10 to 80% charging time

Automakers like to quote charging time either by miles per an amount of time on a charger, or more reliably, the 10 to 80% time. Though some are changing that up, we prefer to test this way. If you’re on a road trip, you’re likely not going to let the car get below 10% before finding a charger, and most EVs slow down their charge rates significantly at 80%.

In fact, we have a leaderboard of all the cars we’ve tested, sorted by the time it takes to complete this test.

The Mach-E Rally took 41 minutes to charge from 10% state of charge to 80% state of charge. Based on the EPA range number, that means it took the car that amount of time to add 188 miles of driving range. This performance is on the slower side of modern EVs, and likely because the Mach-E is still running on the same platform and architecture as it did at launch.

For a once in a once-in-a-while charging experience, this performance is acceptable. But if you expect to find yourself at a charging station more often, some competitors out there will charge twice as quickly. We haven’t tested the Ioniq 5 XRT yet, but our regular Ioniq 5 test had the car completing the chore in just 18 minutes (which is, coincidentally, exactly what the manufacturer claims). That’s due, in part, to Hyundai’s use of 800-volt architecture.

Many use cases will involve the car never being plugged into a fast charger, and for that, you wouldn’t notice the slower charging. It’ll easily charge overnight on a level 2 charger with time to spare. For those people, the Mach-E Rally is a hoot. We would like to see Ford refresh the car with faster charging performance, however.
