The Arona shows impressive control of pollutant emissions and its Clean Air Index of 9.8 is well above the five-star threshold. Effective exhaust after-treatment leads to good results almost across the board, dropping to marginal only for carbon monoxide emissions in the high-load test.

Our verdict

SEAT’s small SUV crossover, the Arona, turns in a strong performance in Green NCAP’s tests. With a 1.5 litre GDI engine and comprehensive exhaust after-treatment, including a three-way catalyst and gasoline particulate filter, the Euro 6d-Temp compliant car scores almost full marks for Clean Air, with an index of 9.8 out of 10. Control of all pollutant emissions is good in all tests except the high-load highway test, where particulate emissions are adequate and CO emissions slip to marginal. In general, though, the after-treatment works exceptionally well and the result for Clean Air is an impressive one. For Energy Efficiency, performance is adequate but unexceptional and the car just clears the four-star threshold. Overall, the car’s rating is limited by its performance in this part of the assessment.
