In this Euro 6b form, the Fiesta scores poorly in many of the tests. Particulate number is high and, in the high-load highway test, emissions of carbon monoxide and oxides of nitrogen are also poor.

Our verdict

Ford’s ever-popular supermini, the Fiesta, has been tested here with the 1.0 EcoBoost engine which complies with Euro 6 emissions levels when tested using the previous test method but not against the latest WLTC (Worldwide-harmonized Light-vehicle Test Cycle) of Euro 6d-Temp. The engine has no particulate filter and struggles with high emissions of this pollutant in all of the lab tests. Very few points are scored in the cold, warm, eco and sports mode tests as a result of particulate emissions and, in the higher-load highway test, other pollutants are also significantly increased, leading to poor performance in the Clean Air Index. On the road, emissions values are similar to those measured in the lab and particulate emissions are actually slightly reduced. The car scores much better for Energy Efficiency, with adequate or marginal performance and an index value of 6.6. All in all, an efficient engine is let down by the lack of a particulate filter, leading to high emissions of this pollutant.
