In November 2015, with collapsing consumer confidence in car testing, Groupe PSA decided to take a unique approach by publishing real-world fuel consumption data for its cars in order to be transparent with customers. It undertook to do this with respected environmental organisations and certification partners. This transparent and responsible initiative towards customers and territories is a world first in the automotive industry.
A reliable framework based on a robust scientific approach:
The real-world fuel consumption measurements come from a test procedure established with two non-governmental organizations, Transport & Environment (T&E) and France Nature Environment (FNE), and have been audited by Bureau Veritas.
The protocol for measuring real-world fuel consumption published on October 2016, 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.
The measurements are comparable to those made by Groupe PSA customers (obtained from independent customer surveys). They show that the procedure designed with T&E and FNE is scientifically robust, reproducible and representative of a typical driver.
Up to now, real-world fuel consumption figures for 40 models are available on the Peugeot, Citroën and DS website. By the end of 2016, real-world fuel consumption figures for 50 models will be published.
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, Groupe PSA, Transport & Environment, France Nature Environnement and Bureau Veritas will extend the same procedure to the measurement of real-world nitrous oxide emissions.
