In other ways, the new Model X 60D will be just like the 75D, with a 130 mile-per-hour top speed and a 0-60 time of 6.0 seconds. Order now and get it in late September, just like any other Model X trim level.
Just three months ago, Tesla scrapped the Model X with the smallest battery pack – the 70D – and replaced it with the 75D. It has been changing battery sizes for years. Given Tesla's recent tendency to sell "smaller" battery packs with some of the capacity limited by software, whether the 60D is really a 75D in disguise remains to be seen.
UPDATE: Tesla has confirmed that this is a software-limited 75D:
[The] Model X 60D will be built with a 75 kWh battery pack, and the additional energy can be unlocked at anytime through an over-the-air software update for $9,500. With the introduction of this model we are not producing any 60 kWh battery packs, a decision that is the most efficient for Tesla and allows us to pass the most flexibility and cost savings along to our customers.
