Diesel technology: BMW models gain top marks for pollutant readings in ADAC EcoTest.

Diesel models from BMW were awarded top marks for their
nitrogen oxide readings in the real-world road test conducted by the
ADAC in Germany. The following models scored maximum points in the
emissions section of the ADAC EcoTest and were graded as
outstanding:

BMW 520d Touring (fuel consumption combined*: 4.8-4.7 l/100 km
[58.9-60.1 mpg imp], CO2 emissions combined*: 125-123
g/km; figures as at 06.12.2018)

BMW 218d Active Tourer Steptronic (fuel consumption combined*:
4.5 l/100 km [62.7 mpg imp], CO2 emissions combined*: 119
g/km; figures as at 10.12.2018)

BMW X1 sDrive 18d Steptronic (fuel consumption combined*: 4.6
l/100 km [61.3 mpg imp], CO2 emissions combined*: 121
g/km; figures as at 10.12.2018)

Munich. The EcoTest organised by the ADAC (the German
automobile association) is a rigorous testing procedure that subjects
vehicles to a thorough examination, including measuring their
pollutant emissions in real-world road driving. A trio of diesel
models from BMW recently achieved the best possible score of 50 marks,
resulting in the award of grade ‘1’ for outstanding. The BMW 520d
Touring performed superbly in the nitrogen oxide tests, with a reading
of less than 16 mg/km in urban driving and under 10 mg/km in rural
driving and on the motorway. The maximum allowed is 168 mg/km. The
ADAC had the following to say about the BMW X1 sDrive 18d Steptronic:
“BMW is dealing extremely well with the issue of emissions. There are
no abnormal figures for any type of pollutant, and the nitrogen oxide
emissions are so low they could even be a record. Even the sensitive
measuring equipment used for the test barely managed to detect any
emissions in some cases.”

BMW models have performed comparatively well in nitrogen oxide
emission tests in the past, too. This was the case, for example, in
the real-world road test conducted by German motoring magazine auto,
motor und sport (issue 19 from 23 March 2017) and the many follow-up
tests carried out by authorities in countries including France, Korea
and Japan. Here, the respective BMW models obtained some of the best results.

The ADAC test results are further proof that today’s BMW diesel
models with state-of-the-art technology produce remarkably low
emissions. Three factors, in particular, are key to achieving this:

  1. Many years of experience with and ongoing improvement of all the
    components used for reducing NOx emissions (e.g. exhaust gas
    recirculation, adsorption catalyst and SCR system).
  2. Use of the very latest exhaust gas aftertreatment technology.
  3. Matching the engine’s configuration to this cutting-edge exhaust
    gas aftertreatment technology at an early stage during the vehicle
    development process.
