I don't think it has a lot of chances of beating tesla if it plans entering the market in two years.
They are not really competing in the same markets, they want to beat tesla's model S by making a sportscar. But tesla aims to bring electric cars to the broader public by focusing on cheaper and cheaper models. While upgrading the model S.
It may beat the model S in the planned specs right now but two years is a lot of time in a fast moving sector like electric cars and tesla is upgrading its model S with a high frequency.
Good points. A Model S starts at $70,000. This only competes with a top of the line Model S. It'll be interesting to see how it stacks up come 2019 (like you say, Tesla has plenty of time to upgrade their current models).
