Back in June, Tesla CEO Elon Musk said in a Fox Business News interview that the company had a deal of some kind with Daimler, the parent company of Smart and Mercedes-Benz. As AutoblogGreen reports, it appeared at the time that Tesla was supplying lithium-ion batteries and other hardware for the second-generation Smart ED, which will begin fleet testing in 2009, though no one would comment officially.

Now, the plot thickens: "StreetImportOnline posted today that someone spotted a Smart ForTwo sitting in front of Tesla's San Carlos headquarters." That's no big deal, of course, except for this little detail: "This time, though, the Smart had no tailpipe and was plugged into the charging station outside the front door." Smart had no comment, naturally.
