Elon Musk, co-founder and chief executive officer of Tesla Inc., speaks during an unveiling event for the Boring Co. Hawthorne test tunnel in Hawthorne, California, U.S., on Tuesday, Dec. 18, 2018.

Tesla will unveil its Model Y SUV on March 14, CEO Elon Musk

said in a series of tweets Sunday

.

Musk said

that the SUV would cost 10 percent more than Tesla’s Model 3 sedan and have “slightly less range” for the same battery.

The tweets may exacerbate Musk’s clash with the Securities and Exchange Commission over the CEO’s unfettered use of social media.

Last week, the SEC asked a federal court to hold Musk in contempt over what the agency saw as a violation of an agreement they struck in 2018.

In that motion, the SEC cited an “inaccurate” February 19 tweet about production. Last month, Elon Musk tweeted — then revised — projections for full-year Tesla manufacturing numbers.
