A scientists' group says Hyundai-Kia has unseated Honda as the greenest automaker in the U.S.
The Union of Concerned Scientists ranks the eight top-selling automakers based on carbon and smog-forming emissions of their fleets.
The group says all eight automakers reduced pollution for the first time.

Hyundai-Kia beat Honda by equipping many models with smaller turbocharged engines. The scientists also say Hyundai-Kia introduced gas-electric hybrid versions of its two top-selling models, the Hyundai Sonata and Kia Optima.
Toyota, Nissan and Volkswagen tied for third place. Detroit automakers, which sell more trucks, finished at the bottom.
