It is possible to save up to 20 % of fuel consumption by energy-efficient driving. This saves your money, as well as the environment. However, ecodriving is a broader term and you can save much more than 20%. It begins with the choice of an appropriate means of transport, continues through choosing the right car at acquisition, energy-efficient driving, smart use of air-conditioning, and ends with environmentally friendly car washing. Ecodriving is the approach, which reduces detrimental effects of driving or mobility on the environment.
Before you use a car, just think about other ways of transport – prefer walking up to 1 km, riding a bicycle or using municipal transportation systems for distances up to 10 km. For longer distances you can travel by public transport.
Also choice of a right car at acquisition will influence subsequent environmental pollution and also driving costs. The most environmentally friendly source of energy is electricity (optimally from renewable sources), then gas (LPG, CNG), hybrid power and then petrol. Diesel vehicles should by equipped with a diesel particulate filter. If you use your car for short drives and for urban driving, choose gas or petrol over diesel. Moreover, petrol vehicles can be retrofitted to LPG, which significantly reduces particulate emissions and fuel costs by half.
There are several measures how to make your driving more energy efficient. Before driving, remove things from your boot that you do not need, keep your tires inflated properly, remove unused roof racks and boxes. All these steps decrease your fuel consumption.
Also drive style can influence your driving costs significantly. Anticipate and maximize use of vehicle inertia. Aggressive driving (heavy braking and acceleration) increases fuel consumption by about 20 %. Do not drive too fast. Cruising at 130 km/h can use up to 25 % more fuel than at 115 km/h. Close the windows for decreasing aerodynamic pressure and turn off electrical appliances, if you do not need them. You will save the fuel.
Air-conditioning can increase fuel consumption more than 2 l per 100 km, so its smart use is very important. In hot sunny weather prefer parking in the shade. Do not activate air-conditioning automatically but turn it off for short trips, when it does not manage to cool down the car interior. Do not set the temperature less than 6 °C. Turn off air-conditioning before the end of your journey to enable humidity to evaporate from cooling system.
Next CEPTA steps with ECODRIVING are demonstration drives with bus and vehicle, design of certification scheme for ecodriving and starting certification of real companies, individual drivers, driving schools. First pilot trainings and certification should be completed at the end of the year 2014 / beginning of 2015. We will inform you about the progress.
