CNET'S QUICK GUIDE: The cleanest cars you can buy

PZEV aka SULEV-PZEV (Partial Zero Emission Vehicle)

Although "Partial Zero" seems like an oxymoron, it's just bureaucrat-speak for "nearly zero" emissions. Both PZEV and AT-PZEV cars match SULEV's tailpipe output, with a few extra conditions. For starters, PZEV and AT-PZEV cars must be spanking clean for the first 150,000 miles (versus SULEV's 120,000 miles), have zero evaporative emissions, and come with a 15 year/150,000 mile manufacturer warranty on the pollution control system. What typically qualifies as a PZEV? Nearly two dozen cars sold in 2006, from mainstream gasoline-powered sedans such as the 2006 Mercury Milan to baby SUVs such as the Mitsubishi Outlander.


2006 Mercury Milan
The bottom line: The 2006 Mercury Milan is about as average as they come, with features sometimes matching but never outstripping the competition. While pleasant enough to behold, the Milan really doesn't offer much to desire.


2007 Mitsubishi Outlander
The bottom line: Although not luxurious, the 2007 Mitsubishi Outlander is quite comfortable and capable. It's a practical and fairly affordable choice for a variety of uses, including outdoor adventure and daily commutes.
