the charging and travel times of our Supertest

The Ford Mustang Mach E has a comfortable range to consider long journeys. It remains to be seen what it is worth in terms of fast charging to take full advantage of it.

The Ford Mustang Mach E is one of the electric vehicles in our Supertest with the best autonomy. We have calculated a value of 350 km all round on our reference course of 500 km, on expressways and motorways with speed limits. But this is above all possible with its large battery, 91 kWh of useful capacity since a recent update. This allows it to perform a magic trick, drawing the eye to the final autonomy rather than to the consumption, which is high in absolute terms. Big battery, big autonomy, therefore, but which must of course be filled. Will the Mustang Mach E be able to do well in this game?

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

For charging on direct current fast terminals, the Mustang Mach E promises a maximum power of 150 kW with its large battery of 91 kWh capacity (98.8 kWh gross). It is thus placed among the good students when reading the technical sheet. But as with the Tesla Model Y, it will be necessary to connect around 10%, or even before, to see the color of the 150 kW. Because if we recorded a peak at 160 kW from the start of our measurement, the curve immediately began to fall. And the latter is rather fast, since the charging power drops below 100 kW a little after 40% charge. If the power is maintained more or less afterwards, there is only 68 kW of power left at 80%. This represents a deviation of -57.5% from the peak observed on this fast charging curve.

In short, nothing new so far. On the other hand, it is well after the 80% that we were impatient to observe the improvements brought by this update. Because before, the SUV dropped directly to 11 kW. A power equivalent to that of a slow charge on a public terminal. According to the manufacturer, it took 52 minutes to go from 80 to 90%. Unthinkable! Now, if the curve collapses just before 81%, it stabilizes at 40 kW, allowing it to go from 80 to 90% in 14 minutes. This is much more acceptable since it allows you to use 10% more battery.

It then takes another 30 minutes to fill up to 100% at a fast terminal. In the end, the exercise of recharging from 10 to 80% claims 40 minutes (38 minutes according to the brochure), and the complete refueling requires an immobilization of 1 hour 24. This places the Mustang Mach E at the level of a Nissan Ariya 87 kWh.

Typical recharge curve
10 to 80% 80 to 100% 10 to 100%
Charging time (in min) 40 44 84
Autonomy gained (in km) 245 70 315

Autonomy recovered: 193 km in 30 minutes

On the highway, the average autonomy between 10 and 80% load is 245 km. This is what we measured with the Model Y (244 km). However, recharging is a little slower, which does not allow the Mach E to do as well by combining its recharging curve with its consumption. In the end, it can gain an average of 193 km of autonomy in half an hour, and is thus very close to entering our club of more than 200 km in 30 minutes.

Autonomy recovered
Charging time (in min) 15 30 45 60
Autonomy gained (in km) 112 193 252 291

Ford Mustang Mach E AWD ER Charging Costs

During our various recharges, the terminals indicated an average of 65.82 kWh billed between 10 and 80% load. A quantity, loss included, fairly consistent with the new useful capacity of the battery. Partner of the Ionity network from the start, the brand with the Blue Oval offers a preferential price list which brings the price down to €0.32/kWh (free subscription the first year, then €149/year). This brings the price of the useful refill to €21. What better to swallow the pill, since this same full would represent a note of almost 45.50 € at the public rate.

In our case, the average cost on the motorway is €8.60/100 km. A very interesting value, but let’s not forget to specify that it could be higher with other operators with, for example, 11.80 €/100 km with Electra recharges or 15.85 €/100 km with Fastened.

Travel time for 500 km: 5 h 04

Despite its high consumption, the Ford Mustang Mach E is one of the electric vehicles capable of stopping once to recharge on a 500 km journey between Paris and the outskirts of Lyon. With the battery almost full at the start (95%), we were able to reach a first fast charging station with 9% charge remaining. An 80% recharge will therefore be sufficient to allow us to cover the remaining 200 km before crossing the finish line with 19% charge.

In the end, we performed a recharge of exactly 40 minutes, in line with our recharge curve. Added to the usual travel time of 4 h 20 and to the times of evolutions on the areas and connection (4 minutes), we count a total time of 5 h 04 to cover the 500 km of reference.

Note that the Mustang Mach E has an onboard route planner. If he does not communicate the charge rate on arrival, he prefers to indicate the remaining autonomy, based on current consumption. Which will not be without unpleasant surprises when putting the wheels on the highway. In any case, it will be necessary to manually add charging stations to the route, by selecting them using the filters offered. On the side of the independent planners, we found ABRP more coherent since it is based well on the useful capacity of the battery of 91 kWh. Chargemap was much more optimistic than reality with a single 25-minute shutdown, since it seems to take into account the raw capacity of 98.8 kWh.

What is the Supertest?

Lovers of numbers and allergic to official data sheets, the Supertest, Automobile-Propre’s new test format, is made for you, bringing together data collected during a test in real conditions and according to a transparent and precise protocol. We will add them the Wednesday following the publication of the second part dedicated to the Ford Mustang Mach E AWD ER to our summary article allowing to compare the values ​​noted of the models tested, which will make all the value of the section.

If you want to go further, do not hesitate to consult our tests and to exchange with the community on our discussion forum.
