Our supertest charging and travel times

The Ford Mustang Mach E has a comfortable lineup to keep long journeys in mind. It remains to be seen what it’s worth in terms of fast charging to take full advantage of it.

The Ford Mustang Mach E is one of the electric cars with the best autonomy in our Supertest. We calculated a value of 350 km on our 500 km reference course, on expressways and highways with speed limits. But this is made possible above all by its large battery, with a useful capacity of 91 kWh since the last update. This allows him to do a magic trick, focusing not on consumption, which is high in the absolute sense, but on ultimate autonomy. Big battery, big autonomy, therefore, but of course it has to be charged. Will the Mustang Mach E be able to perform well in this game?

Ford Mustang Mach E AWD ER fill curve: a useful full tank in 41 minutes

For charging at direct current fast terminals, the Mustang Mach E promises a maximum power of 150 kW with its large battery with a capacity of 91 kWh (98.8 kWh total). Hence, it is placed among the good students while reading the technical report. But as with the Tesla Model Y, you’ll need to plug in about 10% or earlier to see the color of 150kW. Because if we recorded a peak at 160 kW from the beginning of our measurement, the curve immediately started to fall. The latter is quite fast, as the charging power drops below 100 kW shortly after 40% charge. If the power is then more or less maintained, only 68 kW of power remains at 80%. This represents a -57.5% deviation from the peak observed in this fast charging curve.

In short, there is nothing new so far. On the other hand, after 80%, we were eager to see the improvements that this update brings. Because before the SUV directly fell to 11 kW. Power equivalent to slow loading on public terminal. According to the manufacturer, it took 52 minutes to go from 80 to 90%. Unbelievable! Now, if the curve collapses just before 81%, it stabilizes at 40kW, allowing you to go from 80 to 90% in 14 minutes. This is more acceptable as it allows you to use 10% more battery.

It then takes another 30 minutes to charge up to 100% at the fast terminal. Finally, a 10 to 80% charge exercise takes 40 minutes (38 minutes according to the brochure) and requires 1 hour 24 immobilization to fully refuel. This puts the Mustang Mach E on par with the Nissan Aria. 87 kWh.

Typical charging curve
10-80% 80-100% 10-100%
Filling time (min.) 40 44 84
Gained autonomy (in km) 245 70 315

Autonomy restored: 193 km in 30 minutes

The average autonomy between 10 and 80% load on the highway is 245 km. Here’s what we measured with the Model Y (244 km). However, charging is a bit slow, which makes it impossible to do so by combining the charging curve of the Mach E with its consumption. In the end, it manages to average 193 km of autonomy in half an hour, so it is very close to entering our club of more than 200 km in 30 minutes.

Autonomy was restored
Filling time (min.) 15 30 45 60
Gained autonomy (in km) 112 193 252 291

Ford Mustang Mach E AWD ER Filling Costs

During our various charges, the terminals showed a calculated average of 65.82 kWh between 10 and 80% load. The quantity is quite consistent with the new useful capacity of the battery, including loss. The Blue Oval brand, a partner of the Ionity network from the beginning, offers a discounted price list that reduces prices to €0.32/kWh (free subscription for the first year, then €149/year). This brings the price of a useful refill to 21 euros. It is better to swallow the pill, because this will represent a record of almost €45.50 in the same full, public course.

In our case, the average price on the highway is €8.60/100 km. A very interesting value, but let’s not forget to mention that it can be higher with other operators, for example with Electra charging 11.80 €/100 km or Fastned with 15.85 €/100 km.

Travel time for 500 km: 5 hours 04

Despite its high consumption, the Ford Mustang Mach E is one of the electric cars capable of charging once during the 500 km journey between Paris and the suburbs of Lyon. At the start the battery was almost full (95%), we managed to reach the first fast charging station with 9% charge. So, 80% charging will be enough to cover the remaining 200 km before crossing the finish line with 19% charge.

Finally, we did a full 40 minutes of charging according to our charging curve. Adding to the usual travel time of 4 hours 20 and the evolution times in the areas and the connection (4 minutes), we calculate a total time of 5 hours 04 to cover the reference distance of 500 km.

Note that the Mustang Mach E has an on-board route planner. If it does not indicate the rate of payment on arrival, it prefers to indicate the remaining autonomy based on current consumption. It will not be without unpleasant surprises when putting the tires on the highway. In any case, it will be necessary to manually add charging stations to the route by selecting them using the proposed filters. On the stand-alone planners side, we found the ABRP more appropriate because it is based on a useful battery capacity of 91 kWh. Chargemap was more optimistic than reality with a single 25-minute shutdown as it accounted for 98.8 kWh of raw power.

What is Supertest?

For those who love numbers and are sensitive to official data sheets, Automobile-Propre’s new test format Supertest is made for you, bringing together the data collected during the test in real conditions based on a transparent and accurate protocol. We’ll add them to our Wednesday round-up after the second installment on the Ford Mustang Mach E AWD ER is published. allows you to compare the marked values ​​of the tested models, which will give the total value of the section.

If you want to go further, don’t hesitate to take our tests and exchange with the community in our discussion forum.
