The VECTO computer calculation tool was developed by the European Commission to calculate the CO2 results for a complete vehicle or truck-trailer combination, considering its possible missions. Transport operators want to make a well-informed purchase decision and buy the right vehicle that is most suitable for their intended purpose. Every transport operator has different needs or a different mission in mind for a truck, and most trucks are custom-built to meet their requirements. Fuel consumption is key for end-users, representing around 30% of their running costs. Manufacturers perform precise measurements and fuel consumption of their vehicles in accordance with EU type approval to advise customers when buying a new truck.
