So Tesla are now offering 100D as a battery upgrade on the configurator under the 90D (for the X at least). Previously you could only get the 100kWh battery with the performance model. Reports from the US suggest price differential of $3k USD which should translate to approximately $4k AUD. Unless I am going crazy the price difference on the configurator seems to be $16k AUD...? LCT doesn't account for such a big difference. So something is wrong either for US or Aussie configurator?
