Emission Analytics, a specialist company in emissions, has measured the real driving emissions for 12 new cars. The Mercedes CLS 350 d was the cleanest diesel with NOx emissions of only 19 mg/km, well below the 80 mg/km limits.

In case of Mercedes CLS 350 d, Emission Analytics has registered NOX emissions of 22 mg/km on autoroute at 130 km/h, 24 mg/km in the city and 15 mg/km on national roads at 80 km/h.

The average NOx emission level was 19 mg/km, well below the 80 mg/km limits, making the Mercedes CLS 350 d the cleanest diesel in the world.

The new 6 inline 3.0 liter diesel from Mercedes in the 286 HP version has registered the best emissions performance ever. Mercedes has decided last year to replace the current V6 diesel with the new 6 inline diesel with the same displacement of 3 litre for the emissions reasons.

In case of 6 cylinder in line the catalytic converter is much closer to the engine. The new Mercedes 6 inline 3,0 litre diesel can fulfill also the future emissions limits which was discussed in Bruxelles today.
The EU comission plans another 20% reduction of the NOx emissions for 2030. Even so, the Mercedes engine emissions are far lower than an eventually 64 mg/km planned for 2030.

The same engine from the Mercedes CLS 350 d you can find under the hood of the facelifted S-Class saloon. In the future the new 6 inline diesel will be available in E-Class saloon, GLC facelift and on the new GLE and GLS models.

In the same test, Audi A7 50 TDI with the new 3.0 litre V6 TDI with 286 H registered an average of 52 mg/km  (37/149/39 mg/km), Volvo XC40 D4 190 HP 59 mg/km (41/181/43 mg/km), Opel Grandland X 2.0 Diesel with 177 HP Peugeot engine 34 mg/km (29/55/33 mg/km).

All other cars measured were above the 80 mg/km limits, despite some of them have SCR catalytic converter with AdBlue: VW Tiguan 2.0 TDI/240 HP 165 mg/km (392/31/49 mg/km), Jaguar E-Pace D240  265 mg/km (603/73/90 mg/km), BMW X1 xDrive 25d 194 mg/km (334/137/118 mg/km).
