Green score: 45The Elantra is a compact competitor to cars like the Toyota Corolla and Honda Civic. It's also available with a 5-speed manual transmission, but the fuel economy is the same.
ACEEE's "Green Score" is based on tailpipe emissions as well as pollution created in manufacturing the vehicle. Pollution from manufacturing is estimated based on the vehicle's weight. The average vehicle's "Green Score" is 30.
Disposal of hybrid batteries does not pose an environmental issue, said James Kliesch. Research Associate for ACEEE.
"It's generally agreed that batteres in [non plug-in] hybrids are going to last the life of the vehicle," he said
When the vehicle is eventually disposed of, the battery will almost certainly be recycled because of the high value of the nickel it contains, he said.
