How do we calculate the Ecoscore of Euro 6 vehicles?
These are the formulas to calculate the Ecoscore of Euro 6 cars and vans:
Petrol:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 7,01*FC+ 0,333*dB(A) - 12,63)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 5,89*FC)]
Diesel:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*0,5 + 0,011*CO + 1407,75*PM + 5,19*FC+ 0,333*dB(A) - 12,39)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*0,5 + 0,011*CO + 1407,75*PM + 4,25*FC)]
CNG:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 3,67*FC+ 0,333*dB(A) – 11,76)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 2,03*FC)]
EV:
-
Ecoscore = 100*exp[-0.00357*( 2,17*FC + 0,333*dB(A) – 13,33)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(1,16*FC)]
PHEV petrol:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 7,01*FCptr + 2,17*FCEV+ 0,333*dB(A) – 12,98)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 5,89*FCptr + 1,16*FCEV)]
PHEV diesel:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*0,5*25/(25+RangeEV) + 0,011*CO + 1407,75*PM + 5,19*FCdsl + 2,17*FCEV+ 0,333*dB(A) – 12,86)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*0,5*25/(25+RangeEV)+ 0,011*CO + 1407,75*PM + 4,25*FCdsl + 1,16*FCEV)]
LPG:
-
Ecoscore = 100*exp[-0.00357*(0,36*CO2 + 23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 2,91*FC+ 0,333*dB(A) - 12,63)]
-
Ecoscore Air Quality = 100*exp[-0.00357*2.5*(23,17*HC + 101,88*NOx + 0,011*CO + 1407,75*PM + 2,32*FC)]
Of which the following parameters are mentioned on the certificate of conformity:
CO2 CO2 emission (combined) (g/km)
HC for petrol, LPG and CNG vehicles: HC emission (g/km)
for diesel vehicles: the difference between the HC+NOx and the NOx emissions (g/km)
NOx for petrol, CNG and LPG: NOx emission (g/km)
for diesel vehicles complying with Euro 6, this is 0.5 g/km (for more info, click here)
CO CO emission (g/km)
PM the particulate emissions (g/km)
FC(xxx) for petrol, diesel and LPG vehicles: the avg. fuel consumption (combined cycle), in l/100km
for CNG: the average fuel consumption (combined cycle), in kg/100km
for EV: the average electricity consumption (combined cycle), in kWh/100km
for PHEV: the weighted petrol or diesel consumption (combined cycle) in l/100km (FCptr resp. FCdsl) and the weighted (combined cycle) electricity consumption (FCEV) in kWh/100km
dB(A) the noise level (driving), expressed in dB(A)
RangeEV the range (km) of the PHEV in electricity only mode
