Alphabet Soup
LEV I, LEV II, ULEV, SULEV, PZEV.
The NC Zoo Society company car, a 2004 Toyota Prius bought in late 2003, is getting great gas mileage these days. It likes the warmer weather. It just got 55.6 mpg for 455 miles on the last tank of gas and it is getting almost 60 mpg so far on this new tank. (It is doing this after over 116,000 miles of trouble-free service - no brake work, no muffler work, just new sets of tires and regular maintenance.)
That reminded me that the best thing it does for wildlife, our environment and us is measured in another way. It is really good at not putting bad emissions into the air, beyond burning less gasoline.
Low Emission Vehicles (LEVs) are given lane preference in major Northeastern and California cities.
That two-seater Honda that seems to come in just torpedo silver is an ULEV (Ultra Low Emission Vehicle).
My first Toyota Prius, a personal car bought in 2001, was a compact car that was much, much better than that Honda two-seater at keeping gunk out of the air. It is a Super Ultra Low Emission Vehicle (SULEV).
The mid-sized Prius (2004- ?) is a PZEV (Partial Zero Emission Vehicle). It is sort of an SULEV which is guaranteed to perform that way for a long time (150,000 miles/15 years), with a fully-sealed, zero-emissions fuel system.
The mid-sized Prius also beats the compacts and sub-compacts for fuel efficiency.
