DS 4
PureTech 225 petrol FWD automatic
August 2023: The result of this car has been updated. Previously reported Ammonia (NH3) values were incorrect owing to a technical error with the equipment at the test laboratory and a correction has been applied.
The DS 4 enters the test with a powerful 165 kW petrol engine. The car respects the Euro 6 exhaust norm and performs as type approved, with CO2 emissions of about 150 g/km in the laboratory WLTC+ tests, but it doesn't qualify for the additional robustness testing. The Highway Test imposes a challenge for the environmental performance of the DS 4 in all three categories. Here, the vehicle is not able to score any points for Clean Air or Greenhouse Gases and only 1.5 points for Energy Efficiency. The exhaust aftertreatment lacks robustness and fuel consumption is relatively high. This brings the overall rating down significantly to just 2 Green stars out of 5 with a Weighted Overall Index of 3 out of 10.
