Nissan Car 'Clean'

TOKYO -- Nissan Motor Co. on Wednesday staked its claim to having the world's cleanest gasoline-engine car, saying its new Sentra sedan model had met emission standards previously held only by electric vehicles.

"The Sentra CA, driven 10 miles [16 kilometers] to work and back, emits less harmful vapors than an ordinary car sitting in a driveway all day with its engine turned off," Jun Teranuma, general manager of Nissan's powertrain planning department, said at a news conference.

Cars can still emit vapors after the engine is turned off and when left outside in the sun.
