Musk took to Twitter to make the announcement, but has left few clues to the new unveiling besides the declaration that it isn’t a car.
This rules out the Tesla Model X SUV, which was originally believed to begin production in the US summer after a series of delays.
If the ‘X’ is still on track for a northern summer production debut, it now appears that an official unveiling will take place after April’s big announcement - whatever it is.
The Model 3 sedan is also off the list of potential launches, although the 3 is known to be the secondary project to the Model X at this stage.
Musk describes the item as a “major new Tesla product line”, tying it in with his electric vehicle company that currently produces the Model S sedan.
Major new Tesla product line -- not a car -- will be unveiled at our Hawthorne Design Studio on Thurs 8pm, April 30— Elon Musk (@elonmusk) March 30, 2015
Therefore, the smart money seems to be on a new Tesla battery pack for the home.
Musk confirmed earlier this year that the carmaker was working on expanding its battery technology for home use, and a predicted production schedule within the next six months fits with a late April unveiling.
The battery pack is designed to assist people with getting further ‘off the grid’, capable of storing energy from renewable sources such as wind or solar for later use before the occupants resort back to the poles and wires.
Pricing, energy capacity, charging times and more are all still in the ‘unknown’ category, as is the chances that the April unveiling will even be the home battery pack.
We’ll just have to wait until April 30 at this stage, with Musk set to pull the covers off the whatever-it-is at Tesla’s Hawthorne Design Studio in the US.
