Our verdict

The small Citroën C3 reaches a high rating of 3½ stars in the sustainability rating, despite being a conventional petrol vehicle with only mild hybridisation. This is achieved thanks to the low weight resulting in lower environmental impact of the production processes, an adequate exhaust aftertreatment and relatively low consumption figures. As for other conventional vehicles, the most challenging discipline are the greenhouse gases, where the result is moderate.

  • Exhaust treatment is stable and controls particles well, but CO and especially NH3 emissions reduce the score. Low vehicle weight, rear drum brakes, and some recuperation help lower tyre and brake abrasion.
  • The mild hybrid offers limited fuel savings, but the measured consumption values are at the good (low) range of what can be expected as standard performance for this vehicle type. Low mass reduces production energy demand, but the use of a fuel-burning combustion engine limits life cycle performance.
  • Life cycle emissions are 206 g CO2 eq./km, giving a score of 4.9/10. Low production emissions cannot offset the high emissions from burning fossil fuel.

6.8 10 Clean Air

The exhaust aftertreatment shows stable performance and demonstrates adequate and robust control of particle emissions even in high power-demand conditions. Further reduction of the CO output would further increase the score in this part of the assessment. The NH3 emissions control is weak and valuable points are lost in all tests. The vehicle is light and this helps the mitigation of tyre abrasion. The score for brake abrasion reduction benefits from the rear drums brakes and the possibility to recuperate a little of the kinetic energy before applying the friction brakes.

7.1 10 Energy Efficiency

The mild hybridisation has only limited potential in improving fuel consumption and the measured figures are good but only as expected for a vehicle of this type. The real-world on-road drive in cold weather needed 5.5 l/100 km, while the short urban trip demanded 5.9 l/100 km. In terms of life cycle assessment, the total primary energy demand benefits from the low mass and absence of a heavy battery, the production of which would increase the need for energy. Nevertheless, the amounts of fuel needed by a conventional combustion engine limit the achievable score in this section.

4.9 10 Greenhouse Gases

The total life cycle greenhouse gas emissions are estimated to be 206 g CO2‑eq./km, which is enough for a sore of 4.9/10. The low greenhouse gas emissions of the production of the vehicle cannot compensate for the high emissions of combusting the fossil fuel.

Green NCAP comments

The Driving Experience evaluation of conventional vehicles focuses only on the performance in the section 'Consumption and Range'. The Citroën C3's estimated real-world consumption figures are a mostly 'good', with 'adequate' marks in the highway scenarios. The final assessment in this section is 'good'. The consumption readings on the board computer display are accurate.
