On the drive home from work the other day I saw a Small Chevy (I think Cruze) with a small note on the bumper.
NGD2 test vehicle #328. I Did not see an exhaust tail pipe on the car. I live in the St. Louis area and it had normal car license plates. Not any special kind of distinctive lic. plates. Not sure if it was coming from it or not but smelled a ozone like smell while following it.
Chevy testing out a new electric vehicle & power source? Other elect. cars around here do not have ozone smell?
