Man, Tesla's been busy today -- in addition to the announcement of the Model S
and Elon Musk's promise of a sub-$30K electric car in four years
, word on the street is that the company's inked a deal with Daimler AG to supply it with lithium-ion batteries for upcoming electric cars. Daimler's CEO has said the company was open to leasing battery tech to get out an electric Smart by 2010
and it's rumored that the German marque is looking to ditch gas entirely by 2015
, so going to Tesla, which has been working on battery tech for some time, isn't a totally out there proposition. Just a rumor for now -- given Tesla's generally-prickly
relationships with others, we'd wait for an official announcement before getting too excited about a Roadster-powered SLR, but it's certainly intriguing.
