Private cars cover 70% of the total transport of persons in Denmark and thus over 50% of the total energy consumption with regard to the transport sector. Petrol consumption of cars can be dependent on the driving rhythm and evenness of traffic flow. The performance of cars currently to be found on the Danish roads was investigated, and it was found that newer cars, because of sales competition become constantly more efficient to run. They have a higher top speed and can accelerate quickly, but this means that under normal traffic conditions the motor runs at a lower level of efficiency. Small cars seem to have a better fuel economy than larger ones, both in relation to cylinder volume and weight. Yet this can be a disadvantage as traffic in urban areas generally flows unevenly. A smaller car should be able to drive from 20-25 km per liter, it is claimed, and technology should be developed in order to achieve this standard, while at the same time taking safety measures into consideration. The environment should be protected by reducing traffic volume, and cars should in general be both smaller and more robust in construction. Car manufacturers should be made more aware of these demands. The whole process of manufacturing through to scrapping of cars should be subjected to environmental measures. It is also suggested that taxes should be raised on fuels and also on larger cars that contribute more to air pollution.
