Comments

In most of the tests, NOx is well controlled. However, in the more challenging tests such as the cold ambient temperature and high-load highway scenarios, emissions of this pollutant are sufficiently high that the car loses all points for those tests and this reduces the index in this part of the assessment to 4.4.

The A180d scores well in this part of the assessment, with an average fuel consumption of 5.1 l/100 km and an index of 6.2.

Comments

Emissions of CO2 are never excessive and those of Methane, CH4, are very small. However, laughing gas, N2O, a powerful but unregulated greenhouse gas, is not so well controlled and points are lost for emissions of this gas.

Our verdict

The original A-Class came to the market in 1997 and, now in its fourth generation, remains part of Mercedes-Benz's line-up. The car tested by Green NCAP is the 180d, with Daimler's 1.5 litre, turbocharged four cylinder diesel engine. Energy efficiency is a strong point for the car, with low fuel consumption for a car of its weight. For pollutant emissions, the car has selective catalyst reduction, a three-way catalyst and a diesel particulate filter. On the whole, these work well and emissions of pollutants and greenhouse gases are well controlled. Oxides of Nitrogen are the only weak point: in the Clean Air index, NOx is elevated in the more challenging tests and emissions of N2O, a powerful greenhouse gas, reduce the score in that part of the assessment. The indexes in these two areas of assessment reduce the average and result in an overall 2½ star rating.
