Nissan announced yesterday that it will introduce the world’s first super-ultra-low-emissions vehicle in California next year. The 2000 model year Sentra compact sedan has a four-cylinder engine, a super-efficient catalytic converter, and a system that eliminates evaporative emissions from unburned fuel. Nissan says the car will produce fewer total emissions during a 20-mile trip than a typical new vehicle produces while parked in a driveway all day with the engine shut off, because conventional cars emit fumes from evaporating fuel.
