GreenerCars 2023: Efficiency and Weight—Not Just Electric vs. Gas—Shape Environmental Impact

The top five most environmentally friendly cars in the annual GreenerCars ratings are all-electric and the next five are gasoline hybrids. Led by the Mini Cooper Hardtop EV, the Greenest List was rounded out by a mix of EVs and hybrids from Japanese and Korean automakers. EVs are among the least polluting cars on the market, but because powertrain efficiency and vehicle weight also have a significant effect on a car’s environmental impact, some hybrid and gasoline vehicles outperform some EVs.
