The given value was obtained in accordance
with the specified measurement procedure
(the respective current version of the
Directive 80/1269/EEC).
3
Fuel consumption and CO2 emissions
figures are obtained under standardised
test conditions (Directive 93/116/EEC)
using a representative model. This allows
direct comparison between different
models from different manufacturers,
but may not represent the actual fuel
consumption achieved in ‘real world’ driving
conditions. More information is available at
www.dft.gov.uk/vca
Please note: The maximum power output
figures are quoted in PS (or Pferdestärke,
which is the metric equivalent of brake
horsepower). To convert to brake
horsepower, divide the PS figure by 1.0139.

technical data
Depending upon your chosen A8 wheel
size, different efficiency figures for
CO
2 emissions and fuel consumption
will apply (based on EU directive no.
715/2007 effective from 01/09/14).
This table is a quick reference guide
to assist you in finding the correct
values based on wheel sizes and
chosen engine.
