A TOYOTA Prius has clocked up 85mpg on mixed urban and motorway driving with a Northern Ireland-based fleet manager at the wheel. The hybrid petrol-electric Prius is on trial with Northern Ireland's biggest listed company, Viridian Group, and was driven by Harold Baird, fleet solutions manager for Open + Direct Fleet Solution, a subsidiary of Viridian. NIE is another Viridian subsidiary and Baird has been evaluating the Prius alongside all-electric and LPG-powered vehicles.
