Task description:
As crude oil becomes scarcer it will become more expensive. The ever increasing cost of
oil per barrel mean Australians will pay over $1.80 per litre.
As the world’s oil resources decline we must develop different and more efficient ways of providing power
to our societies. Transport of people and goods is a major user of fuel and many companies are
developing vehicles that are far more efficient.
The best known of these vehicles and the most
successful so far is the Toyota Prius. This vehicle
is known as a hybrid car and uses both an internal
combustion engine (ICE) and an electric motor.
Toyota claims performance that compares well to
mid sized petrol cars and fuel economy of around
4.2 litres per 100 kms.
