Following the official release of real world fuel consumption figures for 30 Peugeot, Citroen, 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 three steps: Selecting and checking the vehicle, driving the vehicle and performing the measurement, and 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 Citroen will release the real world fuel consumption figures of another 10 models (including the new Peugeot 3008 and Citroen C3) on their website.

By the end of 2016, real world fuel consumption figures for 50 models tested during the year will be published on the Peugeot, Citroen, 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.
