The steel body panel can be
replaced by thin & strong
carbon fiber nanomaterial
The car weight
can be reduced
up to 15%
The body panel
discharged as
car electric
motor is used
The material recharged by
•Regenerative braking
•Plugging into electric grid

EVs compared to normal cars
Electric vehicles Normal cars
Energy comes from electricity fossil fuels
Where Energy is
stored
rechargeable batteries petrol tank
Engine type electric motor internal combustion engine
Where the energy
is put in
power outlet and
charging cord
petrol cap
Are there any
‘tail-pipe’ emissions?
no yes
12. 12
What does an EV look and sound like?
Looks
like a normal car
Sounds
silent when running
as has less moving
parts
13. 13
Are EVs better for the environment?
• produce 27% less CO2 than petrol cars
• help to reduce greenhouse gas emissions
• Produce no carbon emissions when
powered using renewable energy
14. 14
cheaper to run because electricity is cheaper
than petrol
better for the environment
reduce noise pollution
less environmental impacts across their life-cycle
(manufacturing, use and disposal)
15. 15
Currently more expensive than normal
cars
Not many places to charge your car
Can only travel 100-160km between
charges
Charging can take hours
Silent operation – potentially dangerous for
pedestrians
