Why commercial vehicles differ from passenger cars
Transport efficiency entails picking the most appropriate vehicle for the job. From this perspective, trucks and buses are fundamentally different from passenger cars, which are consumer goods. In the case of trucks and buses, fuel efficiency is ensured by business operation, because fuel costs are a significant part of the overall operational costs. Given the competition between transport service providers for goods and people, strong economic incentives already exist for fuel efficiency improvement through market forces.
Trucks and buses: custom-made improvements
Vehicle innovation is only one of many jigsaw puzzle pieces forming the integrated approach that is necessary to improve fuel efficiency of road transport. Aside from CO2 and fuel economy improvements, modern trucks emit only a fraction of air pollutants compared to their predecessors. In fact, the latest Euro VI models have slashed pollutant emissions to near-zero levels. Moreover, trucks and buses are custom-made on an individual basis, often in a multi-stage process, and adjusted to specific, individual needs regarding load capacity, driving patterns, etc.
