The PSA Group has published the results of real-world fuel consumption tests for 30 core models from its Peugeot, Citroën and DS ranges.

The results come from a test procedure established with two non-governmental organisations, Transport & Environment (T&E) and France Nature Environment (FNE), and have been audited by Bureau Veritas. PSA says these results are reliable and reproducible, and the test procedure measures the real-world fuel consumption of PSA customers.

Based on the European Union’s Real Driving Emissions (RDE) project, the procedure measures fuel consumption by means of a portable emissions measurement system (PEMS) installed on the vehicle. Bureau Veritas, an independent body, guarantees the procedure, ensuring that it is conducted in line with specifications and that the results are reliable.

The measurements were made on public roads open to traffic (25 km / 15.5 mile Urban, 39 km / 24.2 mile Rural and 31 km / 19.2 mile Motorway) and under real-life driving conditions, notably with passenger and luggage loads, road gradients, and the use of air-conditioning systems. The measurements are comparable to those made by PSA customers (obtained from independent customer surveys). They show that the procedure designed with T&E and FNE is scientifically robust, reproducible and representative of a typical driver.

In November 2015, with declining consumer confidence in car testing, the PSA Group decided to publish real-world fuel consumption data for its cars in order to be transparent with customers. It undertook to do this with respected environmental organisations and certification partners. This initiative is believed to be a world first in the automotive industry.

By the end of 2016, the Peugeot, Citroën and DS brands will offer a simulator on their websites to enable customers to predict their vehicles’ fuel consumption based on driving style and conditions (city/country/motorway mix, vehicle load, etc.). At the same time, an eco‑driving application will also be made available online to customers to help them manage their fuel consumption.

Commenting on the announcement, Gilles Le Borgne, Executive Vice President, Research & Development, said: “The PSA Group has today published real-world consumption data for 30 Peugeot, Citroën and DS models, in line with the commitment to transparency made in October 2015. As part of its drive to continuously provide customers with more information, the Group will publish figures for another 20 models by the end of the year and introduce a simulator allowing customers to reduce their fuel consumption depending on driving conditions, thereby lowering their CO₂ emissions. In 2017, the PSA Group will move to the next level by extending measurements to pollutant emissions of nitrogen oxides (NOx) in customer driving conditions.”

Greg Archer, Clean Vehicles Director at Transport & Environment, said: “This real-word test provides more representative information to consumers than new laboratory tests, helping them to choose the most fuel-efficient, low-carbon models.”
