the norm rather an option in their range of cars. This and other initiatives will bring Honda into compliance with new CAFÉ Regulations which provides a Corporate Average Fuel Emissions target which translates to around 120g/km CO2 across an individual Company's fleet. This target maybe achievable for producers of small cars but presents a real technological challenge to manufacturers of larger vehicles. Honda's Hybrid vehicles will make a real difference to achieving this environmental target as will the fitting of Diesel particulate filters to all new Diesel Cars to meet Euro V legislation. Only 5 years after introducing the first Diesel engine (visit http://www.honda.co.uk/change/) the achievements of which include designing a unique casting process available only at Honda in Japan to cast small enough Aluminium engine blocks capable of withstanding the extra compression required for Diesel ignition whilst maintaining a lighter engine for superior fuel efficiencies. Euro V required a reconfiguring of this engine's layout to fit the particulate filter near the warmest parts of the engine to aid in the filter's regeneration. Euro V diesel particulate filtered engines across the board are characterised by the need for a 15-20km driving cycle at 50plus km/h to deal with the particulates generated by Diesel. One attribute of all these vehicles are these critical temperatures required for the processing of the particulates in the engine itself this was the driver for the reconfiguration of the original Honda diesel engine.
