The PSA Group, which owns Peugeot, DS, Citroen and Vauxhall, has published the real-world emissions data for a range of its new models.

It committed to meeting new European emissions standards three-years ahead of their official introduction, in 2020.

As outlined in the table (below), the five models all meet the more stringent Euro 6d-temp standard.

In a statement released by the group, it said: “These good results confirm the performance of the selected technologies and Groupe PSA’s undertaking to meet the targets set by the EU emissions standards three years ahead of schedule.”

Emissions testing will be available for 80% of Euro 6d-temp compliant vehicles sold in Europe, by the end of 2018 in the case of passenger cars and by the end of 2019 for light commercial vehicles. The test protocol will also be extended to Groupe PSA hybrid vehicles in 2019.

Gilles le Borgne, Groupe PSA executive vice president, Quality and Engineering, said: "The excellent test results from our first vehicles demonstrate the validity of Groupe PSA’s technological choices. We have met the current target set by European standards three years ahead of schedule in the case of emissions in real driving conditions. We are pursuing our commitment to transparency with our customers through this undertaking, which was initiated in 2015 and continues to make a difference in the sector.”
