Our verdict

The small conventional Hyundai i20 reaches a credible score of 3 stars in the sustainability rating. The enablers for this achievement are the low weight resulting in lower environmental impact of the production processes, an adequate exhaust aftertreatment and relatively low petrol consumption figures. As for other conventional vehicles, the most challenging discipline are the greenhouses gases, where the result is moderate.

  • The Hyundai's exhaust system performs well, also under high power, and the assessment benefits from low tyre abrasion due to the car's light weight, but does not score points for brake abrasion
  • Fuel consumption is decent, aided by low weight and aerodynamics, but the lack of electrification and reliance on petrol limits both propulsion and life cycle energy efficiency.
  • Life cycle greenhouse gas emissions are 211 g CO2‑eq./km, with fossil fuel combustion CO2 outweighing the benefits of low vehicle production-phase emissions.

The Hyundai i20 demonstrates that small and light modern conventional vehicles with reasonable consumption values and adequate exhaust aftertreatment can play a role in limiting the transport impact on the environment, although their potential to do so is fairly limited by the usage of fossil fuels.

5.9 10 Clean Air

The exhaust aftertreatment shows stable performance and demonstrates robust control of CO2 emissions also in high power demand conditions – a significant improvement compared to previous vehicle generations by Hyundai. Further reduction of the particle emissions output would additionally increase the score in this part of the assessment. The vehicle is light and this benefits significantly the mitigation of tyre abrasion but it has no means of reducing brake abrasion, which scores 0.

6.8 10 Energy Efficiency

The car's petrol consumption figures are good but not surprising for a vehicle of this type. They mostly gain from the low weight and aerodynamic design as there is no electrification support of any type. 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.

4.7 10 Greenhouse Gases

The total life cycle greenhouse gas emissions are estimated to be 211 g CO2‑eq./km, which is enough for a sore of 4.7/10. 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 section 'Consumption and Range'. The Hyundai i20's estimated real-world consumption figures are seen as adequate in all conditions – warm weather and cold winter, urban, rural, highway and mixed driving scenarios. The consumption readings on the board computer display are accurate.
