2.6 LCA results for the new E-Class E 350 e Saloon in
comparison with the predecessor
The plug-in hybrid model E 350 e combines a 65 kW (88 hp)
electric motor with a four-cylinder petrol engine displacing
just under two liters with 155 kW (211 hp).
The high-voltage lithium-ion battery of the E 350 e provides
an energy content of 6.4 kWh. It can be externally charged
from a charging socket and at puplic charging stations. With
the power of the synchronous electric motor, the E-Class
thus has an all-electric range up to 33 kilometres. The quan-
tities of electricity and petrol consumed during the use of
the vehicle were calculated with the certified consumption
values based on the certification rule ECE R101. The electric
energy consumption (NEDC) stands at 11.5 kWh/100 km,
the corresponding fuel consumption is at 2.1 l/100 km.
With regard to generation of the externally charged electric
power, the two variants "EU electricity grid mix" and elec-
tricity from "hydro power" were examined.

Fig. 2-17 compares the carbon dioxide emissions of the
E 350 e with those of the predecessor E 350 CGI, equipped
with only a combustion engine.
In the production phase the E 350 e gives rise to a higher
quantity of CO₂-emissions caused by the additional hybrid-
specific components. Over the entire lifecycle comprising
manufacture, operation over 250,000 kilometres and recy-
cling, however, the plug-in hybrid shows clear advantages.
External charging with the European electricity grid mix
can cut CO₂-emissions by around 44 percent (approx. 29
tonnes) compared to the E 350 CGI. A 63 percent reduction
(approx. 42 tonnes) is possible through the use of renewably
generated electricity from hydro power.
Figure 2-18 shows the nitric oxide emissions over the entire
lifecycle. With the European grid mix the E 350 e is on the
same level as the predecessor E 350 CGI. With renewably
generated electricity from hydro power NOx-emissions will
be reduced by 42 % (23 kg) in comparison to the predecessor.
