A new study carried out by University College Dublin (UCD) academics, published today, has revealed that in typical Irish commuting conditions, Toyota's hybrid powertrain system drives in zero emissions mode (ZEV) for significantly more than half (62 percent) of the time and over 40 percent of the distance covered.

Those were the key findings of a study carried out by four UCD academics and commissioned by Toyota Ireland through ConsultUCD, the University's managed consultancy service.

Study - Energy - Behaviour - Toyota - Prius

The study entitled Energy Behaviour of Toyota Prius Hybrid Vehicles in Sample Irish Commuting Conditions was authored by Professor Robert Shorten and Assistant Professor Giovanni Russo, UCD School of Electrical and Electronic Engineering, Associate Professor Francesco Pilla, UCD School of Architecture, Planning and Environmental Planning and Associate Professor David Timoney, UCD School of Mechanical and Materials Engineering.

Zero emissions mode describes the time the internal combustion engine is not running and the vehicle is therefore emitting no pollutants. The longer the car is in ZEV mode the more significant the air quality benefits for other road users.

Study - Drivers - UCD - Belfield - Drogheda

The study tracked seven drivers who commuted to UCD, Belfield from Drogheda, Wicklow, Aughrim, Smithfield, Blackrock and Dundrum, over a full week each during last November, combined with normal additional family driving. Conclusions are based on the analysis of the more than 2,000 kilometres of driving across motorways, rural roads and city driving that resulted.

The routes reflect typical Irish commuting conditions. The researchers measured the time the cars spent in zero emissions mode versus internal combustion mode. No restrictions or driving guidelines were given to the drivers.

Associate Professor David Timoney, UCD School of Mechanical and Materials Engineering. said, "We were delighted to carry out this study to investigate the energy behaviour of Toyota's hybrid powertrain system across typical commuting conditions in Ireland. Highlights of the study include a high percentage of zero...
