The Volkswagen ID.3 has no more secrets for you in terms of autonomy after the first part of the Supertest. It remains to be seen how it behaves in front of fast charging stations and on long journeys with this second part.
In order to shed light on electric cars and their consumption, we decided to carry out real life-size tests, by having each model studied travel nearly 2,000 km. An opportunity to measure the autonomy on long journeys on the motorway, but also the mixed consumption and the recharging powers on the fast terminals. For this, we have implemented a strict protocol for each car.

Charging curves of the Volkswagen ID.3: a “useful” full in 33 minutes
Apart from the slow charging chapter, where the Volkswagen cannot compete with the Megane e-Tech, it has a fast direct current charging power of 120 kW. This is barely 10 kW less than on the technical sheet of the Renault. According to the brochure, the recharge time from 5 to 80% is 35 minutes. In fact, the ID.3 keeps all its promises, and more: plugged in from 5%, the compact quickly climbed to a power of 131 kW ! This is the maximum that we were able to observe during the test, on a Fastned terminal and without having activated the preheating of the battery.
Then follows a charging curve with a profile modeled on the other curves that we have observed, although with higher power values of 2 kW at most at the intermediate SoCs. The power peak unfortunately does not last, but the high powers hold up to 20% before forming a first step. It is from 25% that the curves of our full recharges met. However, despite barely lower powers, the recharge times are similar down to the minute.
In the end, the 10-80% recharge of the Volkswagen ID.3 requires 33 minutes very precisely. When cold, with a peak of 107 kW at 10%, the same type of charging will only take 1’30” more. Not enough to change the life of a motorist on the long journey. Especially since they will be rare to fill up on a fast charging station in the early morning before leaving. On these 70% load, the Volkswagen gained an average of 41.9 kWh according to the display of the terminals, or 40.6 kWh according to the strict rule of three taking into account the useful capacity of the battery. The difference is small.
DC fast charging curves
The curve forms a final plateau between 70 and 80%. Beyond that, it will take 10 minutes more to reach 90%. In total, the total time is just under 59 min to complete a 10-100%. The percentage hunt has its limits on the motorway since, to go into detail, with the ID.3 you lose almost 20% in 43 km, of which 2% is consumed only when leaving the rest area.
Typical recharge curve
Autonomy recovered: 157 km in 30 minutes
According to our measurements, the Volkswagen ID.3 has a total autonomy of 243 km, or 170 km of useful autonomy. On a fast terminal, it is therefore able to recover 170 km of autonomy in 33 min. Always from a SoC of 10%, it will be possible to gain 97 km in 15 min all round, while it will take almost an hour to count on a motorway range of 218 km.
Still in terms of autonomy, the display is linear in its announcements, but still a little optimistic. According to theoretical calculations, according to all of our motorway readings, it is based on an average consumption of 21.7 kWh/100 km. In reality, this corresponds to a difference in autonomy of a maximum of 10 km. Difference which decreases as the battery charge drops: there is a difference of 7 km at 20%, 3 km at 10% and 2 km at 7%. The SoC/autonomy ratio therefore appears to be rather reassuring.
Autonomy recovered / recharge time
How much do Volkswagen ID.3 recharges cost?
Volkswagen has the advantage of being part of the consortium of manufacturers gathered around the Ionity charging network. With the compact, drivers can benefit from preferential rates via the We Charge identification badge, which gives access to more than 250,000 charging points in Europe. Three formulas exist, with in particular the We Charge Plus offer at €9.99/month the first year, then €17.49/month. In this case, the price at the Ionity terminals drops to €0.30/min.
In other words, the 10-80% top-up costs only €9.90, i.e. a direct cost of €5.82/100 km. Rather attractive for a motorway journey, particularly in the face of the full price of €0.79/min, which would raise the bill to €26.07 (€15.34/100 km). But this case must be taken into account since the badge provided by Volkswagen was not recognized on the Ionity station in Maison-Dieu for example.
Also, the We Charge badge was not accepted at Fastned terminals. Fortunately, if we had a spare Chargemap badge, they also offer the possibility of paying directly by credit card. According to the information communicated by the terminal, the exercise represents a charge of 41.5 kWh, or €24.49, or a cost of €14.41/100 km.
For this trip on the A6 motorway in the south/north direction, we had to top up three times for a net amount (excluding operator fees) of €45.41. That is a total cost of €10.56/100 km before our last stage (a distance of 430 km). As usual, we do not calculate the cost price over 500 km since it is the price of the last recharge to find the starting SoC which will determine the total cost.
On-board route planner, ABRP and ChargeMap: ABRP in the lead (by little)
Last exercise of this Clean Automobile Supertest of the Volkswagen ID.3, the comparison of route planners. Available on the central screen, the navigation of the German electric is particularly pleasant. It takes the trouble to warn that the destination is out of range of the remaining autonomy and displays an isodistance map of the radius of action.
From our starting point, it selects the A7 and A6 motorways which serve as our base to reach the Porte d’Orléans in Paris, the finish line of our journey. With 80% charge available, sufficient to reach the Fastned station at regulatory speeds, the planner nevertheless favors the Ionity terminals, necessarily and a Total station. In the end, he provides for three stops for 1h17 of recharging (a total of 6h25 with the travel times).
The A Better Route Planner application is just as fond of Ionity terminals, with a stop at the three major stations on the route. However, having a better database with this vehicle, the recharge times are quite close to reality, while it makes us arrive at the stations with 10% of charge remaining (except for that of Taponas). In short, according to him, it takes 4h42 of road and 51 minutes of recharging for a total of 5h33.
ChargeMap manages to target the Fastned station in Saint-Ambreuil and the Ionity terminal in Maison-Dieu, but takes us through the Total station in the Couline area. Total operations: 47 minutes of recharging and 4h20 on the road (a total of 5h07). Again, within minutes the cooldowns are pretty much real. Minus the SoC predictions when arriving at the terminals. Proof of this is with the first prediction, where the ChargeMap system predicts a rate of 23% when arriving at the Fastned station.
In reality, we got there with 7% charge remaining. First fill up to 70%: 27 minutes. Enough to earn just enough to reach the Maison-Dieu area, where we achieved a 12-70% in 25 minutes. Finally, last recharge on an Ionity terminal near Nemours with 11 minutes of immobilization.
In the end, our strategy modeled on that of the Renault Megane e-Tech scrutinized a few days earlier results in a journey of 4h22 and 1h03 of recharging for 500 km. By adding the time of the evolutions on the areas, our journey represents 5h37. In the case of the Volkswagen ID.3, A Better Route Planner seems the closest to reality. ChargeMap isn’t far behind, but its slightly overly optimistic first estimate has turned charging times upside down. Otherwise, the SoC consumed/km traveled ratio is the closest to what we have observed in reality. Certainly, this method of calculation is not very rigorous, but it is the one that speaks most to neophytes.
