The Peugeot e-308 is one of the surprises of the year: with its pleasant sobriety, it has nothing to be ashamed of during long highway journeys.
Based on a thermal compact platform, equipped with a traction chain developed for city cars which has proven itself (at least until our detailed test of the Jeep Avenger) and promising a meager rapid charging power of 100 kW, the Peugeot e-308 did not convince at first time. However, it was able to achieve a very good place in the demanding exercises of our Supertest: it notably completed our 500 km motorway journey with a consumption of 19.6 kWh/100 km, or 260 km of average autonomy. It therefore offers a slightly greater range than the Renault Megane e-Tech EV60 and MG 4 Luxury, with a lower battery capacity. But is it enough to go faster on the road? We take stock.
Charging curve for the Peugeot e-308: a useful full tank in 28 minutes
On paper, the Peugeot e-308 uses the same battery as the other vehicles in the group. In theory, it should therefore have the same characteristics as the latter, like the Jeep Avenger. But this is not really the case, whether in terms of recharged energy, compatibility or recharge speed.
And this is also the case in terms of charging power with larger fleeting peaks (we recorded a maximum of 108 kW), but also with, more interestingly, plateaus maintained for longer. When the Jeep presented a stepped curve, the e-308 was able to stabilize the charging power between 25 and 55%. Also, at 80% load, the power was more than 60 kW, while the Jeep ingested 5 kW less. Interesting figures to observe, but which will not change anyone’s life.
|10 to 80%
|80 to 100%
|10 to 100%
|Cooldown time (in mins)
|Range gained (in km)
In the end, the 10-80% exercise was completed in exactly 28 minutes. The end of charging, on the other hand, requires much more time, but is much faster than with the Avenger which nevertheless has the same battery on paper: the compact requires 43 minutes more to go from 80 to 100%, compared to 62 minutes with the Jeep. And it is especially on the 80-90% sometimes useful on long stages that the gap widens, with nine minutes for the Peugeot and a quarter of an hour for the SUV.
Which does not mean that the e-308 revolutionizes the segment with an average power of 84 kW ultimately… average. Finally, let us point out that we did not observe any compatibility problem on the Siemens terminals of Engie Vianeo with this vehicle, unlike the Jeep Avenger which did not want to exceed the 30 kW mark on two different stations.
Autonomy recovered: 187 km in 30 minutes
Thanks to its much lower consumption, the Peugeot e-308 can present correct values in this chapter. Certainly, the 112 km recovered in 15 minutes are not as interesting as the 129 km recorded with an MG 4, but it is as good as with a Ford Mustang Mach-E. It begins to regain the upper hand after 30 minutes with 187 km of autonomy recovered, compared to 185 km with the Chinese compact. The Renault Megane e-Tech will have to wait 15 minutes more (a total of 45 minutes) to regain 186 km of autonomy.

Cost of recharging the Peugeot e-308
Over the course of our various recharges, the terminals calculated on average a “volume” of 39.2 kWh between 10 and 80% charge. We notice here the slight difference in capacity which separates the e-308 from the Jeep Avenger. At the average price of €0.59/kWh observed at Fastned or Ionity, this represents a full tank of €23.13 for a direct cost price of €12.71/100 km. This is very logically the most affordable cost that we have calculated to date. At Total (0.62 €/kWh), this increases the price to 13.35 €/100 km.
Travel time for 500 km: 5h13
The compact’s low consumption at reasonable speeds allows it to go far. It was by bypassing Lyon that the Peugeot e-308 especially did well, before hitting the A6 motorway towards the regulatory-looking capital. This translated to an initial 228km before recharging, averaging 18.8 kWh/100km at that point. So we only did two recharges on this trip to reach the finish line with almost 20% charge remaining.
To the usual journey time of 4 hours 20 minutes, we therefore added 45 minutes of charging time to the total. With a package of four minutes per stop, this brings the complete travel time to 5 hours 13 minutes. The Peugeot e-308 therefore gains almost ten minutes compared to the MG 4, which nevertheless impressed us in this game. But if it benefits from a greater average charging power (109 kW), its higher average consumption (25.4 kWh/100 km) forces it to stop once again.
Supertest Peugeot e-308: the results
The Peugeot e-308 is new proof that you should not trust the values indicated on the technical sheets before setting off on the road. Because if it can blush on paper, the French compact manages to be just as versatile as its direct competitors. Its low daily consumption could appeal to those who want to switch to an electric car, while the autonomy/recharging synthesis is not prohibitive on a long journey. In short, it’s a nice surprise that has nothing to envy of the MG 4 Luxury on the road. Too bad, once again, that the battery capacity is below the segment average.
On the other hand, the Sochaux compact makes people cringe with its price list. Priced from €45,720 in the Allure version and €48,220 in the GT finish, it is placed at the level of a high-end Renault Megane e-Tech which, if it does not go faster to cover these 500 km, offers a more advanced technological endowment. But above all it is much more than a Cupra Born XL, whose versatility of its 77 kWh battery reaches new heights. That’s good, the Spaniard has already passed through our hands and we’ll talk about it again very quickly.
