The PSA Group – which owns the Citroen, Peugeot and DS brands, and will soon own Vauxhall – has published real-world fuel consumption data for 1,000 cars.
Publication of the figures follows on from a statement last year in which the French giant said it would quote the figures in conjunction with campaign groups Transport and Environment and France Nature Environment.
According to the company, 58 models have been tested, with estimations being made using the same engine and gearbox, plus three variants to take into account differing body types, trim levels and tyre dimensions.
In addition, the group has estimated the impact different loads – as in luggage and occupant weights – and driving styles will have on fuel consumption figures.
The figures have been taken using a portable emissions testing device installed on the vehicle, and the readings were made on public roads under real-world conditions, including using air-con and tackling hilly routes.
PSA has published the figures on each of its brand’s websites – click the names of the manufacturers to see the figures: Citroen, DS, Peugeot.
“In line with the commitment we made to our customers, we are now publishing the real-world driving consumption figures for Peugeot, Citroen and DS models on our brands’ website,” said Gilles Le Borgne, executive vice president, of quality and engineering for the PSA Group. “Our customers can now access comprehensive and transparent fuel consumption data. We will add the figures for NOx emissions in summer 2017”.
Greg Archer, director of clean vehicles at Transport and Environment added: “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 carmakers need to follow its lead.”
