Sorry, but Tesla was able to pay the loan back due to good business strategy and increased Model S sales and profitability.The reason that Tesla paid back the loan so quickly is by selling carbon credits. All of Musk's current companies require the governments help to keep them afloat
I hope EM has a similar business philosophy and shared success in getting the loan with an early payback. Go Elio! Go Tesla on the Gen3 due out in 2017.
