Berlin: 20 May 2011 - 21 May 2011
The International Energy Agency is organising a workshop on heavy-duty vehicle fuel economy at the 2011 Bibendum in Berlin. Most OECD countries, and increasingly non-OECD countries, now have fuel economy standards for light-duty vehicles, and there is growing interest in implementing similar regulations for heavy-duty vehicles. The nature and usage of heavy-duty vehicles are obstacles to implementing fuel economy regulations equivalent to those for light-duty vehicles. Heavy-duty trucks are large in size (hence the difficulty to have the entire vehicle measured in the testing laboratory) and there are a significant number of different configurations for a given engine and chassis combination which can have a big impact on duty cycle and fuel economy.

Session 1: HDV technology potential for FE improvement
This session aims at evaluating the cost-effective technological potential to reduce fuel economy of trucks. The cost and level of fuel saving technologies are critical to the successful deployment of advanced technologies in the mass market, as truck fleet operators often perform benefit-cost analyses prior to vehicle purchases, and are sensitive to fuel efficiency gains in operation.
Session 2 : Testing and certification for effective policy to deliver HDV fuel economy
Due to the size of heavy-duty vehicles, and the elevated number of possible chassis and engine configurations, it is not practicable to physically test each vehicle model type on a vehicle dynamometer for the purpose of homologation. This session will discuss practical solutions to measuring emissions and fuel economy of heavy-duty vehicles and to account for variations in vehicle sizes in fuel economy regulation.
Session 3 : Existing / Planned policies
Many countries are looking into the opportunity of implementing a regulatory framework for heavy-duty vehicle fuel economy. This session will examine the lessons learned from current heavy duty vehicle fuel economy policy, what is planned in future policies, what would best practice policy look like? Overall what fuel efficiency gains can be expected?
