Our verdict

Although this is a conventional petrol vehicle, the BMW 120 reaches a relatively high score of 3 stars in Green NCAP's sustainability assessment. The car benefits from its compact size and low mass, its low pollutant emissions and relatively efficient powertrain. The most challenging discipline are the greenhouses gases, where the achievement is moderate.

  • The BMW has efficient exhaust aftertreatment and low tyre abrasion, but limited brake recuperation affects brake emission performance.
  • It offers decent fuel efficiency and benefits from low production energy demand due to its light weight and lack of a battery.
  • Despite lower production-phase emissions, overall life cycle greenhouse gas emissions are moderate due to fossil fuel combustion.

6.7 10 Clean Air

The BMW's exhaust aftertreatment is efficient and robust under a variety of conditions, but the score in this section would benefit from further reduction of particle emissions. Due to the relatively low mass and well controllable accelerator pedal response, the tyre abrasion emissions are low, however, there is no other factor but the limited 48-volt system recuperation possibility to reduce brake abrasion.

6.1 10 Energy Efficiency

The car's petrol consumption figures are good but not surprising, although a standard real-world on-road drive mixed trip with 4.5 l/100 km makes a good figure. 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.

4.0 10 Greenhouse Gases

Although the non-usage LCA phases of a conventional vehicle emit less greenhouse gases compared to an electric car, the combustion of fossil fuels increases the emissions over proportionally and leave the BMW with a mediocre score in this part of the assessment, despite its good consumption figures, given the petrol engine.

Green NCAP comments

The Driving Experience evaluation of conventional vehicles focuses only on the performance in section 'Consumption and Range'. The BMW 120'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.
