Just read an interesting article about the formation of automobile names, and Tesla was positively mentioned! Entire article text found here Excerpt
He obviously has not had anyone read the back of his car and say "What's a TeL-sa"? As a long time vocal fan of the T-man, with more than one T book on the shelf, the company name was one of things that put me over the top in excitement. We proudly love saying we drive a Tesla. Now about the name "Model S"....
A google search on 'model s' brings up a lot of sites with 'models'. I don't want to talk about what happens with 'Model X'.
