PSA Peugeot Citroen release real-world MPG test results

The PSA Peugeot Citroen Group has started publishing the results of its real-world fuel economy tests - the first manufacturer to do so. The French company, which has the lowest CAFE (Corporate Average Fuel Emissions) figure of any volume manufacturer, has released the results from the first round of testing for three of its best selling models, one from each brand.

The use of fuel consumption figures from PSA Peugeot Citroen drivers is extremely close to the real-world testing undertaken by the company, giving creedence to its findings. As you can see, the real-world results are roughly two-thirds to three-quarters that of the current official and reported fuel economy figures.

Although these percentages seem very poor, they are at least in the same area or better than those anticipated from other manufacturers. PSA Peugeot Citroen will release its official real-world fuel consumption figures for 30 Peugeot, Citroen and DS models before the end of summer 2016.

The tests were carried using a protocol developed alongside Transport & Environment (T&E), a respected European non-governmental organisation that campaigns for greener transport. Tests were undertaken on public roads near Paris and under real-life driving conditions, featuring passengers, luggage loads, road gradients, and the use of air-conditioning.

The route was made up of 15.8 miles (25.5 km) of urban roads, 24.7 miles (39.7 km) extra urban, and 19.3 miles (31.1 km) of motorway. This reflects the forthcoming Real Driving Emissions (RDE) test, set to come into force over the next year or so, and measures performance with a PEMS (Portable Emissions Measurement System).

Gilles Le Borgne, Executive Vice-President, Research & Development, said: "As announced in late 2015, after working with Transport & Environment, France Nature Environment and Bureau Veritas, the procedure has now been validated and the initial results are consistent with customer-reported consumption data."

Greg Archer, Clean Vehicles Director at Transport & Environment, said: "The test developed with PSA Peugeot Citroën is reproducible and representative. It confirms the fuel consumption of a tested model by a typical driver in real-world driving conditions. This test proves that the on-road tests are reliable and can be used to measure real CO2 emissions. This should become the benchmark for all carmakers advertising their vehicles' fuel efficiency."

Commenting, Marc Boissonnet, Executive Vice President, Marketing, Sales and Communication at independent auditing body Bureau Veritas, said: "The initiative, based on cooperation between a manufacturer, an NGO and a certification organization, is both innovative and constructive. It meets all the conditions for addressing issues that may be raised by consumers. PSA Peugeot Citroen has done what was necessary to ensure an independent and credible verification that can set the standard for the automotive industry."
