Battery production limitations are the cause.
American EV carmaker Tesla have made the call to push their well-anticipated Semi truck back by about a year or so, as rationalisation with their battery production left them with little choice but to announce that their electric truck will only be making its debut sometime in late 2020. This was confirmed by marque CEO Elon Musk during a stakeholder meeting recently.
“There is not much point in adding product complexity if we don’t have enough batteries; Then that’s complexity without gain. We’re matching the product roll out according to the scaling of battery production; That’s really the main limiting factor.” – Elon Musk, Chief Executive Officer, Tesla Inc.
Musk expressed interest in perhaps increasing its involvement further down the battery supply chain, suggesting that Tesla may go into the mining industry in order to better secure a supply of raw materials with which to make energy storage units.
The Tesla Semi is already well into its prototyping & testing phase, with models spotted here and there doing all sorts of things. Despite being delayed, the Semi is still available for reservation, with a sizeable US$20,000 deposit for the standard model with its 800km range. You can read more about it here.
