A new study conducted by researchers at Cardiff University and Clifford Thames finds that the Prius isn’t the greenest of them all. But how did they come to this conclusion? Well, Cardiff University and Clifford Thames researchers devised an environmental rating system for vehicles (ERV) which takes into account cars’ overall environmental footprint (including raw materials, production and end-of-life costs - based on their length, width and weight). According to the study, in terms of high-volume "city" cars, the Citroen C1 and Toyota Aygo are among the best, with ERV scores exceeding that of the Toyota Prius hybrid. Someone might point out that the Prius is a C-segment vehicle so the comparison is unjust. True, but Richard Barber, Clifford Thames Strategy and Business Development director believes that conventional petrol and diesel cars will quickly outpace Toyota’s Prius on environmental friendliness. -Continued after the jump
"While the Prius is presently the best among vehicles its size, we are seeing advances in traditional powertrain technology that will help other vehicles close the gap or even leapfrog existing hybrid solutions", said Barber.
Even though I’m not much of a Prius fan, I’ll have to disagree with Mr. Barber for the simple reason that the Prius uses multiple propulsion systems to provide power. In other words, the Prius combines a gasoline engine and an electric motor. Therefore, all Toyota needs to do is add a more frugal and environmentally friendly gasoline engine, and it will furthermore increase the distance from its competitors
