the true proof of their autonomy

We tested the autonomy of the Dacia Spring in real conditions. Hopefully for daily commutes, less power consumption would have been expected for such a small car. Not surprisingly, the freeway should be avoided.

Does the cheapest electric car on the market live up to its promise? Answer with our Dacia Spring autonomy test.


DACIA Spring Comfort

  • – Engine: electric
  • – Power: 44 hp
  • – Launch: September 2021
  • – From € 16,990
  • € 4587 bonus.

The Dacia Spring is the curiosity of 2021 because it is the cheapest electric car. This is in line with the reputation of the Romanian manufacturer, which offers cars at bargain prices. And it didn’t win in this segment, where batteries inflate prices. The offer is here: 12 600 € in base price (since the increase in October 2021), after discounting the ecological bonus, pre-orders already open and the first deliveries to private customers promised in September 2021. But this low-cost electric car meets your promises in terms of autonomy? To find out, the Dacia Spring passed our test dedicated to electric cars in a very specific route (see infographics below).

The Dacia Spring passed the two ranges of the autonomy test: 109 km of motorway and 140 km of roads.

The 6.6 kW charger supplied as standard allows Spring Electric to be connected to public terminals.

Before departure, remember the Dacia Spring is short (3.73 m), narrow (1.58 m) and light for an electric (970 kg). It is made in China and will be offered for car rental this spring. It is also a pre-series Business version dedicated to these rentals that we have, but there will be no technical difference for the models intended for individuals. They will have the same electric motor of modest power (44 hp), the same battery with a usable capacity of 27.4 kWh and the same WLTP range advertised at 230 km. Autonomy precisely, let’s go.

What rank in the fast lane?

At 110 km / h, we are still advancing the trucks on the highway!

For spring, we had to change our habits. The highway we usually do at 130 km / h on our GPS was done at 110 km / h to take into account the 125 km / h top speed of the car. And then, let’s be honest: we would not have gone to the end of the 109 km of this route with the accelerator pedal full to hold the 130 flat. In the spring he doesn’t like the highway and not just because of autonomy. It can barely stand 110 km / h on long ramps, its course is uncertain, and it is literally impossible to “catch a wind” when cars pass a little faster.

Fast route 110 km / h Way out Arrival
Battery level 100% 27%
Mileage traveled 109 km
Estimated consumption * 18.4 kWh / 100 km
Estimated range * 149 km

Values ​​calculated according to the percentage of battery consumed (here 73%) and its useful capacity (27.4 kWh) Therefore, we have chosen to rename this test to fast lane autonomy at 110 km / h. Under these conditions, the battery that we had charged 100% to our boot terminal ran out of 73% of its capacity in 109 km. This corresponds to a consumption of 18.4 kWh / 100 km and a range of only 149 km.

The Spring could have done better by recovering energy on foot descents, but its system is not active above 80 km / h. Here we are touching the limits of its technology … Dacia promises, however, that regeneration will be done at all speeds in production models.

What rank on the road?

Blurred direction and inaccurate behavior: Spring requires wise conduct.

Considering the bonus, the price of the Spring starts from € 12,403 in Comfort finish.

After recharging the battery in an Ionity terminal (see next chapter), we start the route by small roads that cross villages, numerous sections at 70-80 km / h and an end at 110 km / h. We have the opportunity to confirm our feelings during the first test of Spring. The mid-point steering is fuzzy, the soundproofing is light, and in the rain, the Chinese tires are real soaps. All this does not prevent the Spring from offering the right advantages for chip jumps from one village to another with sufficient resources despite its low power of 44 hp. In fact, it is the torque of 125 Nm available without delay that saves performance and allows the Dacia to fit into traffic without difficulty. It is also often more sensitive than the Renault Twingo 2, the Citroën Saxo and other well-tired Peugeot 106s, to name a few, which we find in the field. Road route Way out
Arrival Battery level 100%
23% Mileage traveled
140 km Estimated consumption *
15.1 kWh / 100 km Estimated range *

182 km

Values ​​calculated according to the percentage of battery consumed (here 77%) and its useful capacity (27.4 kWh) This time the Spring shows its energy recovery at its counter in all phases of deceleration below 80 km / h, and is an opportunity to point out that the level of regeneration is not adjustable as on board a Renault Zoe. The whole test was done in Normal and non-Eco driving mode, which turns the Spring into a snail with a crushed power of 30 hp and a top speed of just over 90 km / h. On arrival, the consumption on the road is 15.1 kWh / 100 km. A lower score than a Zoe, heavier and more powerful (17.1), but higher than the Volkswagen e-up (11.5), a small city car like her.

Under these conditions, the range on the road is set at 182 km.

against the 230 km announced in the WLTP cycle.

TO READ. Autonomy of electric cars: the results of our tests

Dacia spring recharge The Spring is equipped as standard with a 6.6 kW on-board chargerin alternating current, the power of which corresponds to the Chinese standard. This does not allow you to make the most of the 7.4 – 11 and 22 kW charging stations, which are the most widespread among us in urban areas. For example, it takes 3 h 21 for a 0 to 80% load on terminal 22

kW when the Renault Twingo E-Tech performs this operation in 47 minutes. But in any case, home charging is preferable, and the Spring runs on a full charge (0 to 100%) on a 2.3 kW domestic outlet at 1:32 p.m. Therefore, one connection each evening will suffice. With the optional 30 kW DC charger for € 600, you can connect to fast terminals. But watch out for the bill to “fill in”! Our test Dacia was equipped with the 30 kW DC charger for fast terminal.It is an option at 600 € ultimately not very useful because this type of load is especially interesting for long distances. What spring will not do. In addition, DC terminals are mostly found on motorways, such as Ionity in the Vrigny (Marne) area, located on our test route. In this terminal, we recharged the battery from 27 to 100% in 49 minutes. 100% charge is not recommended because it is long and especially expensive for Ionity, which charges for the connected time (0.79 € per minute) and not per charged kilowatt, which would be fairer. But this full load was necessary to complete our course, and we were charged € 43.55 for 19.07 kWh. Converted to miles, that is€ 43.55 for 107 km at 110 km / h

Don’t…

And the city?

Our tests do not refer to urban use because, under these conditions, the autonomy of modern electric cars is not a problem. Spring is one of them, and it feels like a duck in the city; it is super maneuverable, easy to park and offers good peripheral visibility. Too bad your low-speed suspension is so dry, to the detriment of comfort. It is also in large cities where charging stations are mainly deployed. But we can regret the frequent traffic jams at the stations because rechargeable hybrid cars are becoming more and more common to connect to.
