The cost of recharging and autonomy over a long journey of 850 km

Car of the Year, the Kia EV6, was just made available in an affordable version, with a 58kWh battery. We will examine what the latter can do in a particular long-distance exercise, and see where he stands in relation to the others.

The Kia EV6 is one of those electric cars that offers honorable autonomy, with big promises: the ability to travel with ease thanks to ultra-fast charging. So we’ll examine this in detail using our reference tracks, as we did with the Tesla Model 3 Propulsion and the Tesla Model 3 Grande Autonomie.

The rules remain as usual: Start at 100% battery, finish at 20%, and the vehicle must run at top speeds. We will recall the characteristics of the car (autonomousness, battery, charging power) and compare them with the reality on the ground.

By taking a look at the way the Kia EV6’s 58kWh long rides, you’ll be able to compare it to other vehicles we’ve already encountered in this exercise, to check which one fits your needs, and which works for you. First a good port with as few restrictions as possible.

Kia EV6 58 kWh features

The new 58 kWh Kia EV6 is available on request and has a WLTP range of 394 km. As you will see later, don’t imagine traveling nearly 400 km on the highway, Melting like snow in the sun when driving at 130 km/h.

If the maximum charging power of around 150 kW is not the most impressive, its charging curve is much more, with a filling 10 to 80% battery in 18 minutes in the best conditions, that is, with an average charging power of 135 kW. This is the big advantage of its 800V battery, and this is what gives it a huge advantage over other vehicles in the same range.

Kia EV6

In order to plan our reference trips, we allow ourselves to use various fast charging networks, according to which they prove to be the most practical among Ionity, Fastned, Totalenergies and Tesla Superchargers that are open to all.

As usual, the route planner is used best for planning trips, with the Kia EV6’s default reference consumption of 58 kWh in the rear-wheel drive version. The electric crossover from Kia will have a lot to do in this exercise, given that its consumption at high speed is very high, and there are still certain hubs that are not well supplied with fast charging stations.

Route planning

In the interest of fairness to the various electric vehicles in this series, We start trips with 100% batteryTaking into account that you have to pay for this filling at the average price of a kilowatt-hour in France, currently at 0.17 euros. Then it represents a 58 kWh battery from Kia EV6 9.86 euros. We’ll take this cost into account when evaluating each major flight.

Our reference trip aims to simulate a summer vacation on one side, and on the other a long winter trip. At first, it will be a matter of communication From Orleans to Arcachon, a total distance of about 530 km. Then we focus on 850 km in winter conditions between Caen and Chamonix-Mont-Blanc.

For the summer route, the parameters shown in A Better Route Planner are as follows: 25°C, outside temperature, no wind, arrival at a charging station with 10% battery remaining and 20% arrival at the destination. For a winter trip, it is basically the same, regardless of the weather, as we chose a temperature of 0 ° C.

Balance sheet for different methods

At least two drawings to travel 500 km

Asking for Kia EV6 58 kWh At least two charts to travel from 510 to 530 km that separates Arcachon from Orléans. The first option remains on the highway from start to finish, and requires three stops for charging.

The first shipment is at the Ionity station in Poitiers, 200 km from departure and takes only 9 minutes. In fact, charging the Kia EV6 is generally fast: going from 14% to 50% of the battery is done in less than 10 minutes, at a cost of €14.40.

The second charge of this trip is only 80 kilometers, in the Poitou-Charentes rest area, back in Ionity, with a total of 21 minutes and a cost of 26.80 euros. Finally, an additional 13-minute charge is necessary at Totalenergies in Saint-André-de-Cubzac to reach your destination with 20% battery. With Totalenergies pricing per minute (0.65 euros per minute), this 24 kWh load costs 8.45 euros.

Thus, calculating the starting load, The total price of the summer trip is 60 euros In this first case. Average expected consumption is 234 W/km: total flight time 5 hours 30 minutes (43 minutes charging, 4 hours 46 minutes driving).

Another possibility is to pass through Angoulême and the Tesla Supercharger is open to all (27 minutes of charging for 24.13 euros), after charging at the Ionity station in Poitiers as was the case for the motorway trip (11 minutes for 18 euros).

Thus, this second option only requires 38 minutes of charging twice, in order to travel 510 kilometers for a total travel time of 5 hours 32 minutes. In terms of cost, it is lower than the first option with an extension Total 52 euros. Consumption, too, is planned at 215 W / km.

A winter trip requires concessions

If the summer route described above wasn’t that complicated after all, we’d see that the long winter road connecting Caen to Chamonix-Mont-Blanc isn’t an easy feat to board a 58kWh Kia EV6. Five recharges are required, but in addition, some parts require the driver to reduce his speed, otherwise rallying the next charger is impossible.

It seems that the effect of outside temperature cannot be neglected in the case of EV6, since The first charge at 190 kilometers from the start requires no more than 110 kilometers per hour To comply with the imposed restrictions (at least 10% battery access).

Twenty-six minutes of recharge at Totalenergies (16.90 €) later, towards Aire de la Réserve on the A6, where a long charge is required at Ionity before departure (37 minutes for 35.20 €). This is the only charge that exceeds 30 minutes, but despite this, be careful not to exceed 120 km / h to reach the next available charger in this direction of the highway: the Tesla Supercharger in Beaune.

Only 11 minutes of charging (€13) is required to get to the next Ionity terminal, in Mâcon, where a hefty 25-minute charge (€28.80) awaits. The last charge of the trip should take place in a Tesla Supercharger in Saint-Julien-en-Genevois for 15 minutes (16.60 euros), which allows you to reach Chamonix with 20% of the battery remaining.

In total, this is Approximately two hours of charging are necessary, five stationsat a cost – including home shipping – close to 120 EUR. The journey including fees is only ten hours for these 850 kilometers. The estimated consumption is 268 W / km, which corresponds to a theoretical autonomy of only 215 km, which is clearly far from the promises in the WLTP cycle.

Consumption, recharge cost and autonomy

We summarize costs and shipping times (including home shipping) in the table below. As we go through our examples, you can visualize where the car you’re interested in is in relation to others on a similar trip.

Tesla Model 3 long autonomy 101.3 EUR 1 hour and 2 minutes 8:27 AM
Kia EV6 58 kWh 120 EUR 1 hour 54 minutes 9 hours 59 minutes
BMW i4 147 euros 1 hour and 32 minutes 9 hours and 8 minutes
Hyundai Ioniq 5 145 EUR 1 hour 29 minutes 9:14 am


The big summer trip we chose is coming Cost per 100 kilometers between 10.20 and 11.30 EUR, which is close to a thermal vehicle that consumes about five liters per 100 km. This may sound high for electric cars, but unfortunately that’s the reality of long-distance trips today, with fast charging prices soaring.

In the winter, with a coverage of 120 euros for 850 kilometers, we arrive at a At the rate of 14.10 euros per 100 km, which could be improved slightly. In fact, an offer like Ionity Passport allows for a price go from €0.69 to €0.35 per kWh, but this would require charging a minimum of 635 kWh per year to be worth the cost (i.e. two round trips approx. 1,000 km) otherwise The subscription price (€215.88 per year) cannot be compensated.

Kia test- ev6

With its small 58 kWh battery, The Kia EV6 can be compared to the Tesla Model 3 Propulsion In our long-haul exercise; The American can still do better than the Korean in summer and winter.

In fact, where it took just 31 minutes to push a Tesla Model 3 and between 36 and 49 euros to travel the 530 km between Orléans and Arcachon, it takes between 38 and 43 minutes for a 58 kWh Kia EV6, at a cost of 52 to 60 euros.

For the winter trip, the conclusion is similar: 102 euros, 1 hour and 42 charges for the 3 Propulsion, for 120 euros and 1h54 for the EV6 58 kWh. Despite a much better charging curve, the 58 kWh Kia EV6 doesn’t match its higher consumption It even ranks behind one of its biggest long-haul competitors.

It would be possible to improve charging times, but perhaps not enough, by accepting access with a small percentage of battery at each fast charging station. However, this means taking more risks, which will sometimes be difficult to accept, especially in winter.
