Our verdict

The new Spring, Dacia's supermini, is the first car to achieve 100% in Green NCAP's rating. Tested here is the 48 kW version. The vehicle is designed for urban use and its sustainability analysis profits from its minimalism – the car weighs only 979 kg and features a very small battery of 27.6 kWh usable capacity. The light weight and the small battery are advantageous for all indices. The measured consumption values are not as low as could be expected for such a vehicle, which might be the consequence of compromises with powertrain and heating system efficiency.

  • The Spring has no tailpipe emissions and scores top marks for tyre and brake abrasion due to its low weight and rear drum brakes. Production and energy supply emissions are below Green NCAP thresholds.
  • While generally low, the in-lab measured energy use is higher than expected for such a small car. The on-road test, however, showed very low consumption of 15 kWh/100 km in the mixed scenario and only 11.7 in the short urban trip.
  • The Spring's small size, low mass and tiny battery earn it full points. Lifecycle emissions are 90.4 g CO2‑eq./km, of which 50 come from the car's production in China. Europe's relatively clean electricity mix supports its performance.

10.0 10 Clean Air

The Spring has no tailpipe emissions and scores maximum points on tyre abrasion due to its very low weight. Additionally, the strong brake energy recuperation in normal conditions and the use of drum brakes on the rear axle, which do not allow brake dust to enter the environment, ensure a top performance in brake abrasion reduction as well. The pollutant emissions associated with the production of the vehicle and its battery, as well as those related to the supply of the electric energy, are below the lower Green NCAP thresholds.

10.0 10 Energy Efficiency

The consumption values are low but, surprisingly, more could have been expected by a vehicle of such size and mass. The light weight certainly helps, but the electricity use could have been lower, as Green NCAP has observed with other city and supermini vehicles. The numbers include the charging and discharging losses of home charging. None of the in-lab test consumption values is as low as the 13.3 kWh/100 km from the legal test. Naturally, the Highway Test increases the demand, although the car did not reach a speed higher than 125 km/h. The energy demand difference is low between the cold and warm start winter tests at -7°C. A PTC heater is used for the heating. The on-road test showed very low consumption of 15 kWh/100 km in the mixed scenario and only 11.7 in the short urban trip. The energy needed in the other life cycle phases is low and in total the car's lifetime primary energy demand stays below the thresholds.

10.0 10 Greenhouse Gases

The relatively low consumption figures, the small size and the low mass, as well as the very small battery ensure the Spring collects all points in this index, as well. The total life cycle greenhouse gas emissions are calculated to 90.4 g CO2‑eq./km, of which 50 are contributed by the vehicle production in China. The comparably low greenhouse gas intensity of average European electricity generally benefits all electric cars.

Green NCAP comments

The Spring is positioned in the low-end price range and this might become visible in some aspects of daily use. Tested here is the top trim 'extreme', which brings the highest equipment level.
