A Real-World Fuel Consumption Test Protocol Developed By Groupe PSA, T&E, FNE & Bureau Veritas Provides Accurate Information ...

Regulatory News:
After 18 months of testing 60 vehicles with over 430 road
tests covering more than 40,000 km, Groupe PSA (Paris:UG), FNE,
T&E, and Bureau Veritas publish a detailed report on their
real-world fuel economy findings.
The test protocol is highly reproducible with a margin of
error of just ± 3%. The roughly one thousand results not
only match internal PSA data from their customers but also the
information uploaded by drivers themselves onto public web-based
data sets such as Germany's www.spritmonitor.de.
The Spritmonitor results are within ± 0.2 litres per
100km driven.
The development of the real-world fuel consumption test protocol
commenced in late 2015 and has involved a substantial testing
effort with the objective to cover 80% of the volumes sold by
Peugeot, Citroën and DS brands, both for passenger cars and light
commercial vehicles.
The tests performed on passenger cars reveal an average fuel
consumption of 5.8 litres/100km, and confirm an average gap
with official type approval figures of 1.74 l/100 km. The results
that show PEMS* tests provide a robust, representative and
repeatable basis for measuring real-world fuel economy and CO2
emissions. The results are accurate within 0.3 l/100km.
The measurements carried out under the Protocol provide some
relevant information:
- The tests show that on-board computer
gives reliable information to the driver.
- A diesel car consumes 1.5 l/100km less
than a gasoline one.
- In urban conditions, the gap between
certification and real-life data is equal for diesel (2.4l/100km)
and gasoline (2.5 l/100km) when expressed in litres/100km but is
higher for diesel (53%) compared to gasoline (42%) when expressed
in percentage.
- A diesel car’s efficiency is less
sensitive to driving style than that of a gasoline car.
- Fuel consumption is lower on cars with
a manual gearbox than with an automatic transmission (- 0.4
l/100km).
For PSA, the purpose of this Protocol was to give full and
transparent information to customers regarding the real-world fuel
consumption of Peugeot, Citroen and DS models.
The measurements obtained on the 60 models make it possible to
estimate the consumption in real-world driving conditions of more
than 1,000 versions of Peugeot, Citroën and DS vehicles. For each
model, the estimates have been made using the same engine and
gearbox, plus three variants: body type, trim level and tire
size.
Peugeot, Citroën and DS brands offer their clients the
possibility to check their average consumption in real-world
driving conditions by logging onto their respective websites. A
web-based application allows them to view this data for their model
by entering its characteristics (body type, trim level, engine,
gearbox and type of tyres).
Customers can also estimate their own consumption based on the
actual use of their vehicle (number of passengers, load, driving
style, etc.). The application is now available on the brands’
websites in 12 European countries.
Gilles Le Borgne, Executive Vice President, Quality and
Engineering, for the PSA Group explained: "The Protocol developed
with T&E and FNE is a reliable response to the questions our
customers may have concerning their consumption. They can access
comprehensive and transparent fuel consumption data audited by
Bureau Veritas. We will add the first figures for NOx emissions by
the end of 2017".
Greg Archer, Director of Clean Vehicles at Transport &
Environment (T&E), said: “These real-driving tests show that it
is perfectly possible to achieve CO2 emissions and fuel consumption
figures almost identical to those obtained by drivers on the road.
But real-driving tests are only part of the solution to the
emission cheating scandal. The upcoming EU decisions on how and who
approves cars for sale will be key to ensuring the system of
testing and approving cars is independent and rigorously
enforced."
Philippe Lanternier, Executive Vice-President, Corporate and
Business Development at Bureau Veritas added: “The protocol has
proven to be extremely reliable for real-world fuel consumption
tests. We are confident this extensive experiment can be
successfully replicated to effectively measuring NOx emissions.
This new step will contribute to further increase the reliability
of automotive tests and measurements”
