No Tier iiii won't really have a effect it started in 2011 with engines over 130KW and this year with engines over 57KW. It won't really effect markets but will have a major effect on manufactures. The reason for this is that tier iiii is an interim part and tier iiii final in 2014 for 130KW and 2015 for 57KW will cause major problems as these will need a SCR system. From what i know there are manufactures who are having problems with the smaller trucks from 6,000kg with EGR that is mainly available these stem from heat and room when the SCR system is added that will cause more problems as major design changes will have to happen to fit the add blue tank and SCR system. In larger truck people who use a Volvo engine have the choice of the two system EGR or SCR some have decided that to go SCR would be better as this will meet tier IIII final. Cummings on the other hand only have EGR so they are stuck at the moment. Trucks under 5,000kg do't have this problem as there engines come from the automotive industry and are quite clean this is the main market in both North America and Europe.

What will be interesting will be will Asian manufactures want to develop a new range of trucks that are for a market that they don't sell much in and have the associated cost's.When there own markets don't need these new standards. In North America these big trucks are mainly Taylor or Hyster and in Europe Linde kalmar and hyster do well
