Difficulties in Model 3 production line, as well as relief efforts in Puerto Rico, have delayed launch to today
The all-electric Tesla truck is predicted to have a range of at least 300 miles when it is unveiled tonight at 4am GMT (8pm in Nevada).
Experts claim that the battery pack required to enable that range will weight around nine tonnes, with the lorry itself able to tow around 36 tonnes of cargo.
Tesla boss Elon Musk delayed the official unveiling of the brand's first lorry following production difficulties with the Model 3. Recent weeks have been spent ironing out 'production bottlenecks' on the Model 3 production line, as well as helping Puerto Rico with its power supply following Hurricane Maria.

The bottlenecks have hindered Model 3 deliveries from Musk's initial delivery plan, set out in Tesla's second quarter plan, with 220 Model 3s delivered in the third quarter compared with a targeted 1500.
Musk first revealed an image of the lorry and gave details of its performance during an interview with academic media outlet TED in June. He also announced the product on social media, describing it as 'unreal', but did not give any further details on its capabilities.
According to reports from Reuters, Tesla is aiming to crack regional hauling in the US. The lorry is expected to have an advanced level of autonomy.
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 to produce greater torque than any lorry currently on the road and that it could pull a diesel-engined equivalent uphill in a contest.
Moreover, Musk 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 those on Tesla cars, 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 US semi-lorries or a bluff front like European ones has yet to be seen. The latter is the more likely solution.
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.
