Fuel consumption, CO

Directive 80/1268/EEC (last c hanged
by 2004/3/EG) has ap plied for the
measurement of fuel consumption
since 1996.
The d ire ctive is orie nte d to a ctual driving
practice s: Urban driving is ra te d at ap prox .
1/3 and off-road driving with approx . 2/3
(urban and extra-urban consumption).
Cold starts and acc eleration phas es
are also ta ken into conside ration.
The s pe cific ation of C O
2 e miss ion is
also a constituent of the directive.
The figures giv en must not be taken a s a
guarantee for the actua l fue l cons umption
of a pa rticular v ehicle.
All values are bas e d on the E U bas e mode l
with s tand ard e quipm ent.
The c alcula tion of fuel c onsumption as
specified by directive 2004/3/EG takes
account of the v ehicle’ s k erb weight,
as certained in accordance with thes e
reg ulations. Op tional e xtras may result in
