A) Tightening CO 2 targets require investments in
electrification and use of lightweight construction
OUTLOOK
GOVERNMENTS AND CUSTOMERS EXPECT REDUCTIONS IN CO 2 EMISSIONS
The three largest economies
in the world have passed strong
regulations with regard to CO 2
emissions. Europe, as a leading
regulator, aims to reduce CO 2
emissions by 27% by 2021.
CO 2 targets can be achieved
through:
Investments in engine efficiency –
traditional combustion engines
are optimized while alternative
technologies such as electrical
engines are developed.

Reduction in overall car weight –
every car weight reduction of
100 kg results in a decrease of
~6-7g CO₂/km. Depending on
costs and target customer groups,
different degrees of weight
optimization are pursued.
HEAVY INVESTMENTS IN ENGINE EFFICIENCY
• CO 2 targets are difficult to meet solely through engine
efficiency or lightweight materials
• Investments in alternative powertrains
(e.g. hybrid or electrified) will become necessary
CO 2 REDUCTIONS THROUGH WEIGHT OPTIMIZATION
• Lightweight materials are hard to process but allow
for new designs and product differentiation
• Electrified powertrains increase vehicle weight
and trigger need for weight optimization
