PSA Group measuring real-world fuel consumption


PSA Group real world fuel economy tests

Following the official release of real-world fuel consumption figures for 30 Peugeot, Citroën and DS models in July 2016, the PSA Group, Transport & Environment (T&E), France Nature Environnement (FNE) and Bureau Veritas are fulfilling their commitments and publishing the test protocol, a reliable framework based on a robust scientific approach.

The protocol for measuring real-world fuel consumption defines the means (necessary equipment) and methods (measurement and processing) that should be systematically applied to calculate the average real-life fuel consumption of the average customer. The protocol breaks down into the following three steps:

  • selecting and checking the vehicle
  • driving the vehicle and performing the measurement
  • processing the measurement results

The measurements should be taken when the car is being driven by a non-professional driver on public roads open to traffic and under real-life driving conditions, with normal use of air-conditioning systems, passenger and luggage loads and road gradients.

In addition to the results already published in July 2016, Peugeot and Citroën will release the real-world fuel consumption figures of another 10 models (including the new Peugeot 3008 and Citroën C3).

By the end of 2016, real-world fuel consumption figures for 50 models tested during the year will be published on the Peugeot, Citroën and DS website. At the same time, a simulator to enable customers to predict their vehicles’ fuel consumption based on driving style and conditions will also be released online.

In 2017, the PSA Group, Transport & Environment, France Nature Environnement and Bureau Veritas will extend the same procedure to the measurement of real-world nitrous oxide emissions.

PSA Group, parent company of French car brands Peugeot Citroen and DS, released initial findings from its own real-world fuel economy tests in July 2016. The data revealed that some models are thirstier than official figures by as much as 40% under realistic driving conditions, and that every one of the 28 core models put under scrutiny exceeded official figures by more than 23%.
