Since 2012 Elon has been saying Tesla will have an "affordable" car available in "three to four years."
Problem is that if that were true that should have meant a 2016 release for Model E. If he keeps saying "3-4 years" in 2014 then we are talking about a 2017/18 release at best.
At some point you have to show a concept and put some real resources into actually designing/building/testing and prepping the factory for mass production of Model E.
If we don't see some concrete action on this front in 2014 I am afraid Elon may have been a bit ahead of himself as to when a truly affordable EV will be available from Tesla and we will be looking towards the end of the decade for Model E, which would be disappointing.
Here's to seeing something of substance from Tesla in 2014 on the Model E!
p.s. I understand they are super busy and have their hands full with Model S and X production but a concept shouldn't be too hard to keep our hopes up in 2014!
