Hi all, After the announcement made by the HK Govt that Electric Cars will remain FRT exempt until March 2017, I am now much more seriously considering ordering a Tesla Model S. One question I have is on the battery which has an 8 year warranty and is expected to last around 10 years. The battery is the most expensive component of the vehicle with some estimates that the 85kwh battery costs around US$20,000. Once Tesla builds its Gigafactory in 2020, one would assume that the battery cost should be at least 30% cheaper in around 6 years time and maybe half the cost by the time you have to replace the battery which wouldn't be the end of the world as a major service on a BMW or Benz wouldn't cost much less than US$10,000 after 10 years of running. If anyone has information on this, it would greatly be appreciated. Cheers.
