in 2012, with revenues of approximately $19B, the company made a net profit after taxes of 13%. I estimate separately that their gross profit to be around 33% depending how it is calculated. Porsche sells about 140,000 autos/year
Tesla with Model S and X could exceed that number and have a ASP=$90,000. It could exceed that number of the Tesla is able to get improved battery tech gives its hi end autos 500 miles plus ubiquitous supercharger use. They key enabling tech are increases in battery energy density and lower cost/KW-hr.
GenIII could be the game changer at $35,000 or lower.
