Peugeot S.A (PSA) has announced their plans to publish real-world fuel economy and emission reports for their best-selling models. The company, which handles both Peugeot and Citroen, says the cars will be tested on the road, mimicking day to day driving conditions.

The reason behind PSA's announcement is to make a preemptive move following Volkswagen's “dieselgate” scandal. PSA also said that Peugeots and Citroens have never been fitted with “defeat devices” found in the VW's. In a recent in-house test, PSA randomly selected 4,300 cars for emission testing to check if the cars conform to the Euro 6 standards. All 4,300 cars passed the random test.

At the moment, all cars made by PSA are equipped with a selective catalytic reduction (SCR) technology across its entire Euro 6-compliant diesel-powered passenger vehicles. According to The International Council on Clean Transport, Peugeots and Citroens have the most effective NOx treatment technologies available in the market. As a result, PSA says their cars are compliant with the new WLTP - Worldwide test procedures which will be the standard by 2017.

PSA will now be conducting tests on its main models (best-sellers) and publish their product's real-world fuel economy figures and share it to the public. The company wants to do the testing “as soon as possible” alongside an independent adjudicator to verify the results.
