"the old 0-60 time"
The _current_ 0-60 time, you mean. Especially with this:
"And Tesla only compares with cars currently in production."
considering this is only a teaser tweet, there's a slight hint of irony there. "Currently in production" is also very different from "fastest production cars". Very selective.
This happened last time Tesla announced something like this - people fell over themselves to install it in the Wikipedia page for fastest production cars. Even though it was: 1) not yet available, 2) not verified, and 3) described even by Tesla themselves as an "expected result". i.e. a press release.
When that didn't work, they took to the page to add a new column to the list of accepted results, to add, effectively "manufacturer projected results", with the end result looking entirely silly and forced - a top 20 chart with Tesla being the only one to have a result in a "not real, not yet" column.
