The PSA Group, the parent company of Citroen, Peugeot and DS Automobiles, has published a second set of “real world” fuel consumption figures. This follows an initial set of test results released in March.
The first set of results concerned the group’s 1.6 litre turbo diesel four-cylinder engine, but the second release covers 30 core models for the group, and includes 1.2 litre petrol and additional 1.6 litre and 2.0 litre diesel engines.
The models tested include some not offered for sale in Australia, including the Peugeot 108 and Citroen C1 and Citroen C3 city cars, but also include the Citroen C4, C4 Cactus, C4 Picasso, and Peugeot 2008, and 308.
Real World Testing involves driving a road loop in Paris agreed to by France’s Transport And Environment, and France Nature Environment non-governmental bodies.
A portable emissions measurement device records the results, which are described as "reliable and reproducible". The drive route includes 25 km of urban driving, 39 km rural driving and 31 km on the motorway and includes a passenger and luggage, with the air-conditioning switched on.
As an example of the newly published figures, the Peugeot 308 1.2 litre PureTech went from a previous 4.6 l/100km rating to a newly recorded 6.6 l/100km, equipped with a six-speed manual transmission and 16-inch alloy wheels.
Across the models tested, increases of between 1.2 l/100km and 2.7 l/100km were recorded, however variations between the European models tested and their related variants available in Australia mean direct comparisons are difficult to make.
PSA Group executive vice president of research and development, Gilles Le Borgne, promised that test results for another 20 vehicles would be released before the end of the year.
"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” Le Borgne said.
The PSA Group has led the charge to offer fuel figures based on the new test regime, rushing to beat other European automakers in attempt to provide accurate data to consumers in the wake of Volkswagen’s diesel emissions scandal.
In 2017 the PSA Group will also add NOx emissions figures to its list of results.
