Lamborghini’s gorgeous car concept the Sesto Elemento has 50:50 chance of making it into production.  Even if it does get into production it will be very low volume like the Reventon was.  Sesto Elemento, meaning the sixth element in Italian, is named after carbon (which is the sixth element on the periodic table) because most of the car will use carbon fibre for light weight and strength.  This car will become the most expensive in the world if does get into production.  There must be some ultra rich who must be hoping with fingers crossed that the car will make it into production.
