Finally, real-world fuel-use figures

Paris, France - PSA Peugeot Citroen has published “real-world” fuel consumption figures for three of its diesel cars, seeking to win over wary customers in the wake of Volkswagen’s #Dieselgate pollution cheating scandal.

Peugeot Citroen said the initiative was a world first, launched in the aftermath of Volkswagen's admission in September 2015 that it had fitted 11 million diesel engines worldwide with devices to fool official pollution tests.

Car pollution: real-world tests coming

Carlos Tavares, chairman of the group's managing board, said on the sidelines of the Geneva International Motor Show: “We were obviously shocked by what happened with Dieselgate and in some way, like the profession, the whole automobile industry, we were affected by the situation and deeply upset.

“It was important to safeguard our customers' trust in relation to knowing their cars’ consumption,” he said.

Peugeot Citroen said the results were based on tests designed by two environmental groups, Transport & Environment and France Nature Environment.

The cars were driven on public roads in town, outside town and on motorways near Paris in “real-life” driving conditions with passengers, luggage, roads with hills and the air conditioning switched on.

The company promised to reveal the real-world fuel consumption results for 30 models “before summer 2016”.


As expected, all the “real-world” fuel consumption figures exceeded the results of the existing official laboratory-style New European Driving Cycle tests, which were thrown into question by the Volkswagen scandal.

The “real world” tests showed:

A Peugeot 308 used 5.0 litres over 100km, compared to just 3.2 in the NEDC tests.

A Citroen C4 Picasso MPV drank 5.6 litres for 100km, compared to four litres in the NEDC tests.

And the DS3 premium hatch needed 4.9 litres to drive 100km, compared to 3.6 in the NEDC laboratory.

All three cars had 88kW, 1.6-litre turbopdiesels with manual gearboxes.

New official tests called the Worldwide Harmonised Light Vehicles Test Procedures, aimed at better measuring real-world fuel or energy consumption and pollution emissions are being defined for introduction in 2017.

For now, the official NEDC tests are the only recognised thermometer for car performance in Europe, said Gilles Le Borgne, head of research and development at Peugeot Citroen.

“If others want to join our initiative we would be delighted,” he said, adding however that no other manufacturer had shown interest in doing so.

Peugeot Citroen first announced the real-world testing initiative in November 2015, two months after the #Dieselgate scandal broke.
