After more than a decade of making cars and SUVs – and, more recently, solar panels – Telsa now plans to bring out electric semi-trailers.

Elon Musk’s company plans to unveil an electric semi-trailer on Thursday night local time in Hawthorne, California.

The move fits with the CEO’s stated goal for the company of accelerating the shift to sustainable transportation.

But the semi also adds to the chaos at Tesla, which posted a record loss in the third quarter. It’s already way behind on production of the Model 3, a new lower-cost sedan.

Tesla hasn’t released any details about the semi, but some analysts expect it to have a range of more than 300 kilometres.

Musk has said it should take about two years to bring the semi to market.

He boasted about the plans in a tweet earlier this week: “This will blow your mind clear out of your skull and into an alternate dimension.”
