This new 308 Hybrid HDi demonstrator represents another step on the path towards the planned commercialisation of the technology in 2010. Further evaluation of the original Peugeot 307 Hybrid HDi demonstrator in 2006 has confirmed the choice of a diesel engine, instead of a petrol engine, as the best option to provide the best reduction in fuel consumption and emissions.
The demonstrator is powered by Peugeot’s most efficient parallel hybrid powerplant to date, combined with a 6-speed electronically controlled manual gearbox. It has a 110 bhp 1.6 HDi DPFS diesel engine coupled with a 22 bhp electric motor providing a maximum power output of 132 bhp, comparable to that of the 308 with the 2.0 litre HDi DPFS 136 bhp diesel engine. Fuel consumption in the combined cycle is 83 mpg and 90g/km of CO2 or a reduction of 38% compared to an equivalent 308 diesel HDi model.
In addition, the engine has been designed to meet the future Euro V directive which comes into force in 2009 and offers the possibility of driving exclusively in electric or “ZEV” (Zero Emission Vehicle) mode for journeys in regulated urban centres.
The excellent aerodynamic performance of the 308 hatchback and the use of Michelin’s new Energy Saver tyres, which reduce rolling resistance, help to enhance further its performance.
Compared to the previous 307 Hybrid HDi demonstrator presented in 2006, the focus of the development has now switched to concentrating on the packaging of the hybrid technology into the structure of the new 308, and to ensure its compatibility with the future Euro V emission standards.
