Comments

The Duster generally performs well in its control of pollutant emissions. However, oxides of Nitrogen (NOx) are high, especially in the cold ambient temperature test and the high-load highway cycle. This is reflected in the on-road tests where NOx is again the weak point.

Overall, energy efficiency is marginal. In the warm test, a fuel consumption of 5.1 l/100 km is adequate but this is offset by the performance in the high-load highway test, where consumption increases to 7.4 l/100 km

Control of methane is good. However, emissions of Carbon Dioxide and control of Nitrous Oxide is weak or poor in all tests.

Our verdict

This is the second generation of the Duster from Renault subsidiary Dacia and debuted in October 2018. With its affordable price, the Duster aims at a widespread audience. A 1.5 litre in-line 4-cylinder Diesel engine powers the car tested here, delivering 85 kW and a very hefty 260 Nm of torque. The exhaust after-treatment system includes selective catalyst reduction and a diesel particulate filter, and the car is approved as Euro 6d-Temp. Overall, the vehicle offers reasonable fuel consumption values and CO2 emissions. The exhaust aftertreatment fulfils the legislative requirements and provides very good particle emissions control. Some improvement may help to reach better robustness also with regard to the NOx emissions, which are in general well handled by the abatement systems. Better control of ‘laughing gas' emissions (N2O) would lead to a higher greenhouse gas index. As it is, this index is the car's weak point, at just 2.8 out of ten, and leading to a 2½ star rating.
