With consumer confidence in claimed fuel economy figures in tatters post Diesel Gate, one manufacturer has released the results of new real-world fuel economy tests for thousands of its cars.

PSA Groupe, owners of Citroen, Peugeot , DS and now Vauxhall and Opel brands, has tested thousands of its Citroen, DS and Peugeot models using new test protocols established with environmental group Transport & Environment and France Nature Environment and verified by Bureau Veritas.

Gilles Le Borgne, Executive Vice President, Quality and Engineering, for the PSA Group explained the approach: “In line with the commitment we made to our customers, we are now publishing the real-world driving consumption figures for Peugeot, Citroën and DS models on our brands website. Our customers can now access comprehensive and transparent fuel consumption data. We will add the figures for NOx emissions in summer 2017”.

To conduct the new test, which is based on the European Union’s Real Driving Emissions (RDE) project, a portable emissions measurement system was fitted to 58 vehicles across the three brands. The cars were driven along a 57-mile route that included urban, rural and motorway driving in ‘normal traffic conditions’ and with air conditioning turned on.

The readings were used to estimate real-world consumption figures for more than 1,000 versions of PSA Group cars, and this data has now been released to the public. Anyone who already owns or intends to buy one of the group’s cars can now check real-world data through each manufacturer’s website.

Significant differences

Unsurprisingly, analysis of the test results show real-world consumption figures significantly worse than those previously claimed.

For example, a Citroen C4 Cactus running the BlueHDi 100 engine manages 78.5mpg on the combined cycle, but PSA’s real-world testing registers it at 56.5mpg.

Meanwhile the Peugeot 3008 with a 1.2-litre PureTech 130 engine managed 37.2mpg in real-world conditions, compared with 55.4mpg in official testing.

Greg Archer, Director of Clean Vehicles at Transport & Environment, said: “The partnership with PSA Group highlights three key issues. First, that on-road tests to measure real CO2 emissions are reliable, representative and reproducible. Second, that a car company recognises there is consumer demand for robust real world information. And third, in an era of ‘alternative facts’ and dishonest manipulations of emissions tests one company has seen transparency and openness as the way to re-establish trust with its customers – more car makers need to follow its lead.”
