The Mitsubishi i-MiEV has been named as the greenest car of 2012 by the American Council for an Energy-Efficient Economy (ACEEE).
It is first time in twelve years of the ACEEE’s annual greenest list that an electric car has come top, with the i-MiEV claiming the highest ever Green Score-at 58-since rankings began in 1998.
What’s more the Mitsubishi’s tiny electric car has knocked the Honda Civic Natural Gas from the top spot after an impressive run of eight years.
In the 14th annual list, the Honda Civic CNG came joint second with the Nissan Leaf, followed by the Toyota Prius, the Honda Insight, and the Smart ForTwo. Hybrids dominate the greenest list occupying half of all the top ten spots. Highly efficient conventional petrol vehicles also continued to have a presence on the greenest list, claiming three of the top spots.
All vehicles are analysed on the basis of a Green Score- a singular measure that incorporates tailpipe emissions, fuel consumption, and emissions of gases that contribute to climate change.
This year the environmental assessments were improved too in the generation of Green Scores to more accurately estimate vehicles’ environmental impacts. These include improved emissions estimates for the vehicle manufacturing process, changes reflecting current natural gas extraction practices, and consideration of upcoming shifts in the generation mix for the electricity used to power electric cars.
The winning car, the i-Miev is to make is making its model year 2012 debut on the American market. With a combined city and highway fuel economy of 112 miles per gallon equivalent according to the official US EPA rating, the i-MIEV outpaces all other vehicles currently sold in United States. “
Even taking into account the emissions generated from the electricity used to power the i-MIEV, it still handily outscores other vehicles on the market today,” said ACEEE lead vehicle analyst Shruti Vaidyanathan.
