Musk’s other tweet, concerning the much-discussed Tesla pickup truck, suggested that the company would unveil its design “in 18 to 24 months.”

That would put the date sometime between October 2018 and April 2019.

Pickup trucks are a huge and very profitable segment in North America, with the Ford F-Series lineup of trucks the country’s single best-selling vehicle.

GM, Ford, and Fiat Chrysler make a disproportionate percentage of their profits from those trucks, which now have an average selling price of more than $40,000 each.

Startups exist for that segment too, notably Workhorse (now owned by Amp Electric), which has proposed an all-electric pickup truck.

Similarly, Bollinger Motors will unveil its electric off-road utility truck this summer.
