Thank you for the alert. To clarify, they shipped cars. Each of them included a drive train with two motors and two inverters, tested as an overall assembly according to ECE R85. Tesla's specifications reflected the above.
Did you buy a car or a drive train?
It's like Coca-Cola saying "the water in our product is 100% sugar-free". But as a consumer, are you actually able to drink just the water part of a Coke, or do you have to drink the whole lot with all that sugar in it?
A specification for a part of a product that is not achieveable in the final product is not useful to consumers because we're not buying the product to take it apart and only use the parts that have been rated. We're buying the product to use it as a whole, so we're interested in the specs of the product as a whole.
