Elon Musk says Tesla will unveil its Model Y crossover on March 15, 2019, a date he admits to choosing at random.

Quizzed by a Twitter fan about an unveiling date for the Model Y, Musk responded with a simple tweet reading ‘March 15’. He went on to clarify that he just made that date up “because the Ides of March sounded good.”

The Ides of March corresponds to March 15 on the Roman calendar. It was also the date that Julius Caesar was murdered in 44 BC. Despite picking a date out of nowhere, Musk said a mid-March premiere would work with the automaker’s current plans.

“But consider it real. We could unveil Model Y anytime from late this year to mid next year, so March 15 is about right.”

If Tesla does indeed stick with this date, it will come roughly a year before the Model Y is expected to reach the production line.

Last year, Musk claimed that the Model Y would use a bespoke platform. However, a decision has since been made to use the Model 3 architecture to make things that little easier. Despite using familiar underpinnings, Tesla does intend on working hard to ensure the Model Y is a significant step up from the Model 3. In fact, Musk asserts that it will require just 328 feet of wiring in its construction, down from the 5000 feet of wiring in the Model 3 and the 10,000 feet found in the Model S.
