All late model vehicles use catalytic converters in the exhaust systems as part of the emissions systems required by the federal gov. These units help convert any partially burned fuel in the exhaust into a less toxic vapor emissions. These emissions will basically show up as vapor and will sometimes cause water to drip out of the tail pipe. So it is water that you will see and in small amounts is totally normal. You will notice that when vehicles are cold these emissions will be greater and will show up more. I wouldn't drink it...lol. Hope this answers your question.

It is water. Water is one of the byproducts created when gasoline is burned. Ordinarily you can't see it because it's created as water vapor but on a cold day it condenses into water.
