Examples
Examples of hybrid vehicles delivering SULEV emissions performance include the Honda Insight and Toyota Prius.
A conventionally powered example is the Ford Focus SULEV variant.
Honda's 2006 Civic Hybrid is another example of a SULEV vehicle, in addition to getting almost 45 miles per US gallon (5 L/100 km; 54 mpg). Honda was one of the first car makers to offer SULEV vehicles, starting with 2000 model year Honda Insights (Though only the CVT version attained this rating. The manual transmission version, due to its Lean burn, got a ULEV), one model of the 2000 Honda Accord (special SULEV version of the EX 4-cylinder model, available in California) and the Natural Gas powered Honda Civic GX.
Honda's factory built Civic GX model, which runs on compressed natural gas (CNG), remains in a category by itself. In years past it has been rated the cleanest internal combustion engine on the road, achieving an Advanced Technology Partial Zero-Emissions Vehicle SULEV (2) rating. Made in Honda's East Liberty, Ohio, plant, it was introduced for fleet-purchase only in the 1998 model year but has since been available to all consumers.
BMW's SULEV 325i, 325Ci, and 325iT were introduced in the 2003 production year with the BMW M56 motor to meet new emission requirements. The updated 2.5 liter engine, designated M56B25, was produced between 2002 and 2005. It was the first BMW SULEV.
The M56B25's power output and vehicle performance was the same as the comparable model equipped with the M54B25 engine (US only: BMW M54). The M56 SULEV models listed above were sold in California, New York, and Massachusetts as 2003 models and in Vermont starting in the 2004 model year.
In addition, these BMW vehicles were certified as Partial Zero Emission Vehicles (PZEV): they meet the SULEV tailpipe emission standard, which is approximately 1/5 of the ULEV standard, and they conform to the Zero Evaporative Emissions requirements.
PZEV is a more stringent variant of the SULEV standard. The Hyundai Elantra PZEV, the Subaru Legacy, Forester and Outback 2.5i PZEV, the Volkswagen GTI 2.0L Turbo PZEV, and the Volkswagen Jetta 2.5 PZEV are available in the U.S. state of California in compliance with this standard. Lexus introduced the Lexus RX400h luxury SUV in 2006 with the SULEV rating. Lexus marketed the LS600h L sedan in 2007 delivering SULEV performance. All 2012 Subaru Imprezas sold in the United States after April 2012 met the PZEV standard.
Many SULEV vehicles are only available in LEV-II states. These include California, New York, New Jersey, Vermont, and Massachusetts.
