Over the last 15-20 years petrol and diesel vehicles have become far cleaner in terms of their ‘air quality’ emissions (i.e. pollutants that affect human health). There have also been some improvements (though less marked) with conventional fuelled vehicles’ fuel consumption and CO2 emissions. Local pollution, climate change and fossil-fuel dependency are the main driving forces behind the development of new technology solutions for transportation. The growing environmental awareness of the society is being reflected by the demand for cleaner policies. Vehicle and fuel markets have been responding positively.
Classical vehicles have been improving regarding to consumption and emissions, meeting the demands of stricter emission regulations. New and cleaner fuels are being tested and used and new concept vehicles and components have been developed to use them. The concept of vehicle itself has been constantly changing (new shapes, sizes, uses, functions). A new transport vision is being created.
