Control of pollutant emissions is generally good or adequate. However, in the high-load highway test, emissions of carbon monoxide and of particulate are sufficiently high that no points are scored in that test.

Our verdict

The Subaru Outback is tested here with the flat-four, 2.5 litre engine and “Lineartronic” – a continuously variable transmission (CVT). The car has a three-way catalyst but no particulate filter and complies with the latest Euro 6d-Temp emissions standards. In general, control of pollutant emissions is adequate or good. However, in the cold test, emissions of carbon monoxide and particulate emissions are elevated and, in the high-load test, they are very high, probably as a result of fuel enrichment in such load conditions. Nevertheless, the car achieves a Clean Air Index of 6.5. Its Energy Efficiency Index, however, is just 1.8 and this limits the car to a one-star rating. Energy consumption is high in all of the tests but especially so in the high-load test, for which no points are scored. Overall, the car performs reasonably for in the Clean Air assessment, but at the expense of energy/fuel efficiency.
