An excellent result for the Leon 2.0 diesel. Emissions of all pollutant are very well controlled by the exhaust after-treatment of a three-way catalyst, selective catalytic reduction and a diesel particulate filter, leading to an index of 6.7 in this part of the assessment.

Comments

Good performance here too from the SEAT. Emissions of CO2 are not excessive and those of Methane, CH4, are extremely low. Only those of N2O, a potent greenhouse gas, are elevated in some tests but the car still achieves an index of 3.6 in this part of the assessment.

Our verdict

August 2023: The result of this car 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 Leon, part of the SEAT line-up since it was first introduced in 1998, greatly impresses in this fourth-generation 2.0 diesel form. Equipped with the latest emissions abatement technology - three-way catalyst, selective catalytic reduction and a diesel particulate filter - the car scores well in all three areas of Green NCAP's assessment. Pollutant emissions are very well controlled and energy efficiency is high, helped, no doubt, by the well-matched seven speed automatic gearbox with which the test car was equipped. Emissions of N2O reduce performance for greenhouse gas emissions to a relatively low index of 3.6/10 but the Leon emerges from Green NCAP's tests with a solid and very creditable 3 star rating.
