The XC40 scores well in most tests for pollutant control. However, in the high-load highway test, emissions of carbon monoxide are sufficiently high that all points are lost.

Energy efficiency is, at best, marginal. In 'sport' mode, efficiency is weak and, in the high-load highway test, it is rated as poor and no points are scored.

Our verdict

Volvo’s small off-roader, the XC40, is tested here as the T5 variant, with a two-litre petrol engine and automatic gearbox. The car has a three-way catalyst and a gasoline particulate filter, and these help it achieve a Clean Air Index of 6.8. In the lab tests, pollutant emissions are generally well controlled but the high-load highway test results in poor control of particulate number, limiting the car’s Clean Air Index. However, the star rating is determined by the car’s performance in Energy Efficiency and, here, it achieves an index of only 2.3. Energy efficiency is marginal in most of the lab tests and poor in the high-load cycle. Overall, the car achieves reasonable control of pollutant emissions but is let down by its poor energy efficiency.
