New Ratings for the 'Greenest' Car in America Might Surprise You
The Washington Post shares some surprising news from the American Council for an Energy Efficient Economy, a 44-year-old nonprofit which works on government energy policies and produces its own research and analysis. The group "has rated the pollution from vehicles for decades," according to the article - but "says the winning car this year is the Toyota Prius Prime SE, a plug-in hybrid that can go 44 miles on electricity before switching to hybrid.""It's the shape of the body, the technology within it, and the overall weight," said Peter Huether, senior research associate for transportation at ACEEE. "And all different types of Priuses are very efficient...." [T]he Prius Prime also won out in 2020 and 2022. But with more and more electric vehicles on the market, the staying power of the plug-in hybrid is surprising. The analysis shows that simply running on electricity is not enough to guarantee that a car is "green" - its weight, battery size and overall efficiency matter, too. While a gigantic electric truck weighing thousands of pounds might be better than a gas truck of the same size, both will be outmatched by a smaller, efficient gas vehicle. And the more huge vehicles there are on the road, the harder it will be for the United States to meet its goal of zeroing out emissions by 2050. The GreenerCars report analyzes 1,200 cars available in 2024, assessing both the carbon dioxide emissions of the vehicle while it's on the road and the emissions of manufacturing the car and battery. It also assesses the impact of pollutants beyond carbon dioxide, including nitrogen oxides, carbon monoxide and particulate matter - all of which can harm human health. The Toyota Prius Prime received a score of 71, followed by several all-electric cars such as the Nissan Leaf and Mini Cooper SE with scores in the high 60s. The Toyota RAV4 Prime, a plug-in hybrid SUV with 42 miles in range, got a score of 64. One gas hybrid, the Hyundai Elantra Blue, made the list as well - thanks to an efficient design and good mileage. At the bottom of the list were large gas-guzzling trucks such as the Ford F-150 Raptor R, with scores in the 20s. So was one electric car: the Hummer EV, which weighs 9,000 pounds and scored a 29... The Prius Prime outranked its competitors, Huether said, because of its small battery - which lowers the emissions and pollution associated with manufacturing - and its high efficiency. The vehicle's battery is less than one-tenth the size of the battery on the monstrous Hummer EV.
