PSA Peugeot Citroen real-world fuel consumption 1

PSA Peugeot Citroen has nothing to hide when it comes to fulfilling its transparency commitments to customers. Recently, the company published real-world fuel consumption data for its cars, which it claims makes it the first carmaker to adopt such an approach.

The results were obtained from a test procedure that PSA Peugeot Citroen established together with two non-governmental organisations – Transport & Environment (T&E) and France Nature Environment (FNE). Bureau Veritas audited the results. The three vehicles tested were the Peugeot 308, Citroen C4 Grand Picasso and DS3, with all three being powered by a 1.6 litre BlueHDi 120 diesel engine with a six-speed manual.

Testing of the vehicles were done under a protocol developed with the NGO Transport & Environment. This includes running the vehicles on public roads near Paris (25.5 km urban, 39.7 km extra-urban, and 31.1 km motorway) and under real-life driving conditions.

Therefore, passenger and luggage loads, roads gradients, and the use of air-conditioning systems, all play a role in obtaining the fuel consumption data. Based on the European Union’s Real Driving Emissions (RDE) project, the protocol measures fuel consumption by means of a portable emissions measurement system (PEMS) installed on the vehicle (as seen in the photos).

According to PSA Peugeot Citroen, the measurements obtained from testing are comparable to those made by customers (obtained from independent customer surveys). Therefore, the company concludes that the testing procedure is representative of a typical driver.

The fuel consumption results under the protocol for the vehicles are as follows: Peugeot 308 (5.0 l/100 km), Citroen C4 Grand Picasso (5.6 l/100 km) and DS3 (4.9 l/100 km). Meanwhile, the consumption measured via customer surveys are: Peugeot 308 (5.0/5.1 l/100km), Citroen C4 Grand Picasso (5.5/5.7 l/100 km) and DS3 (5.1/5.3 l/100 km).

Referring to the brochures of the models listed here, the Peugeot 308 has a claimed fuel consumption (mix of urban and extra urban) of 3.2 l/100 km. Meanwhile, the Citroen C4 Grand Picasso claims to do 3.6 l/100 km, while the DS3 brochure states the hatchback does 3.6 l/100 km.
