Our verdict
The name 'Passat' has almost become a byword for dependency and reliability. Tested here as a 140 kW 2.0 litre turbocharged diesel, and equipped with some very up-to-date exhaust after-treatment, the car turns in a mixed bag of results. In the Clean Air assessment, selective catalyst reduction manages to keep Oxides of Nitrogen (NOx) in check in the less demanding tests. However, in the cold ambient temperature test, the high-load highway test and the heavy-load on-road tests, values of NOx are very much higher and the car loses points. The test laboratory also noted the high frequency of DPF (diesel particulate filter) regeneration - every 200 to 250 km or so. During these regenerations, emissions of NOx and of particulates increased significantly and approached legislative limits. Energy efficiency is good for a car of this size and power. Emissions of N2O lead to a poorer score for greenhouse gases than in the other areas of assessment, but the car nevertheless emerges with a respectable 2½ star rating.
