To continue to improve air quality, tighter standards are needed. The California Air Resources Board Super Ultra-Low Emission Vehicles (SULEV) standard is the cleanest emission standard that a gasoline vehicle can meet.

SULEV represents today's state-of-the-art in emissions control, and is a substantial leap forward compared to the current federal standard. A SULEV-rated vehicle approximately 90% cleaner than the average new car. SULEV standards are based on a 120,000 mile lifetime instead of a 100,000 mile lifetime for Tier 1 standards.
