Performance-measurement study conducted by the ADAC

The Volkswagen Group’s current generations of diesel engines are on the cutting edge in terms of efficiency and emissions

The diesel engines being produced by the Volkswagen Group today are among the market’s best in terms of emissions and mileage, according to an extensive performance-measurement study conducted by the German auto club ADAC. Based on the average result, the cars in the Group’s brands that were tested by ADAC largely already meet the limits for on-road tests that will take effect next year with the introduction of the EU6d emission standard. As a result, the Volkswagen Group is right on track in terms of its current engine generations. It is also working on the next evolutionary stage of more fuel-efficient, low-emission internal combustion engines that will be introduced to the market in 2019.

A far-reaching performance-measurement study conducted by the German auto club ADAC shows that the current generations of diesel engines used by the Volkswagen Group are among the market’s best in terms of emissions and mileage – based on the average, many of these engines already meet the emission requirements that will take effect next year with the introduction of the EU6d standard.

The ADAC has just released an analysis of nitrogen oxide emissions (NOx) of Euro 6 diesel engines. Of the 188 models tested since 2013, vehicles made by the brands Volkswagen, Audi, SEAT, ŠKODA and Porsche turned in the best performances – together with the cars made by two other German companies. The ADAC Eco Test determined that the average performance of all products of these companies already meets the threshold for on-road tests of the emission standard EU6d (168 mg/km NOX) that is scheduled to take effect at the end of 2018. The 10 cars with the lowest emission levels in the study include the Sharan 2.0 TDI (88 mg/km NOX), the Passat Variant 2.0 TDI (84 mg/km NOX) and the SEAT Ateca 2.0 TDI (76 mg/km NOX).

Last fall, measurements made by the independent European environmental organization Transport & Environment confirmed that cars equipped with the Euro 6 diesel engines of the Volkswagen Group were among the lowest-emission vehicles in the competition: Nine of the 12 lowest-emission vehicles were made by the company.

Measurements made by the German environmental group Deutsche Umwelthilfe produced similar results: On average, the emission levels of the 12 diesel vehicles made by the Volkswagen Group (initial registration 2016) that were tested under real on-road conditions were lower than the threshold set by the EU6d standard that will take effect at the end of next year. The vehicles included the Audi A5 2.0 TDI (40 mg/km NOX), the Audi Q3 2.0 TDI quattro (48 mg/km NOX), the VW Passat 2.0 TDI Variant and the VW T6 Transporter 2.0 TDI (both 118 mg/km NOX) and the ŠKODA Octavia 2.0 TDI (135 mg/km NOX).

Measurements done by the independent institute Emissions Analytics showed that, among the top 19 tested vehicles, 11 diesel-powered models of the Volkswagen Group received the grade A for the best air quality index.

The German Environmental Protection Agency and the German Environmental Ministry recently said that, ideally, environmental premiums should be exclusively used to promote the purchase of the latest EU6d diesel vehicles that comply with emission standards on the road because this is the only way to accelerate the modernization of vehicle fleets. As a result, the Volkswagen Group is on right track with its current engine generations. It is also working on the next evolutionary stage of more fuel-efficient, low-emission internal combustion engines that will be introduced to the market in 2019.
