 The Toyota Prius has been rated as one of the cleanest vehicles sold around the world based on smog forming and toxic emissions.With a 5 Star Euro NCAP safety rating and lower emissions than any car in its class, 40% lower than European standards for 2005, and with 87% fewer smog forming particles than an average new petrol only car, it has been calculated that each Prius with carbon dioxide emissions at 89g/km, saves well over a tonne of CO2 a year compared to a normal petrol only car (181g/km), let alone a people carrier or a black taxi (243g/km).Ecoigo have equipped their 150 car fleet with wireless Internet, allowing customers to use Wi-Fi inside the vehicle throughout their journey.
