The all-electric Tesla truck will have a range of 200-300 miles / 320-480km when it is unveiled on October 26.

Musk made the announcement on social media, although 'tentatively' pinned the date. He also described the truck as 'unreal', but did not give any further details on its capabilities.

According to reports from Reuters, the brand is aiming to crack regional hauling in the US. The lorry is expected to have an advanced level of autonomy.

Tesla CEO Elon Musk revealed the image when detailing the brand’s future product plans and gave details of the truck’s performance during an interview with academic media outlet TED in June.

Musk claimed that the heavy-duty, long-range HGV is capable of the heaviest class of haulage permitted on US roads.

The lorry is also claimed by Musk to produce greater torque than any lorry currently on the road and that it could pull a diesel-engined equivalent uphill in a contest.

Musk also insisted that the truck could be driven around "like a sports car" and that he was surprised by a development vehicle’s nimbleness when he drove it.

Much of the lorry’s styling is hidden in the preview, although the lights draw inspiration from the design of Tesla cars’ lights, with L-shaped daytime running lights.

Aerodynamics also appear to be a focus of the truck, which has a sleek, tapered cabin. The front section is hidden; whether it will have a long nose like American semi-lorries or a bluff front like European ones has yet to be seen. The latter is the more likely solution, though. 

Tesla also has a Model Y small SUV, an electric cargo van, a minibus and a pick-up truck all slated for introduction in the coming years.
