The four-seat convertible will also do the quarter mile in 8.9 seconds, which would be another record for a production auto. Pulling a fully load at 80,000 pounds, it would be 0 to 60 in 20 seconds.

Elon Musk describes what Tesla Semi can do.

Tesla also has a lot on its plate right now with trying to deliver its new Model 3 to customers in a timely fashion.

A software update previous year put the Tesla Model S P100D second only to the Porsche 918 Spyder in terms of acceleration, reaching 60 miles per hour in 2.28 seconds compared with the 2.2 seconds of the Porsche. It was a typical Tesla event, full of twists, shocks, and plenty of smoke and mirrors.

All Tesla Semi models come with Enhanced Autopilot to help avoid collisions, plus its centred driver position ensures maximum visibility and control, and a low centre of gravity prevents rollovers.

The semi's drive systems are guaranteed to last for 1 million miles, Tesla said. Musk claims that truckers will be able to charge at their origin or their final destination while they unload their freight, or take a 30-minute break from the road, leave their rig on a Megacharger, and have enough power to drive up to 400 miles.

The cost of the Semi Truck outright is not yet known but is said 20 per cent cheaper per mile than diesel lorries, with a cost of $1.21 (£0.91 approx) per mile compared to conventional diesels' $1.51 (£1.14 approx) per mile. These are business people not fans, and they will need convinced that this truck is better for their balance sheet than existing technology.

But Tesla has pulled back recently due to concerns about Model 3 production and integration issues with Tesla's acquisition of solar panel company SolarCity - a firm co-founded by two of Musk's cousins.

Tesla sold just 222 Model 3s from July through September. Speeds can reach up to 104 kmph, which is more than what the diesel trucks achieve, while the battery range is around just above 800 km at highway speeds.

"I hope you like what you see", said Musk.

Automotive News quoted Karl Brauer, executive publisher of Kelley Blue Book, as saying that "Elon's showmanship remains intact".

And in a surprise announcement, Musk also used the event to reveal a new sports auto he claimed would be the "fastest production vehicle ever" made. "So far that final element has eluded Tesla Motors, which makes it hard to see these vehicles as more than "what if" concept cars". Electric truck sales totaled 4,100 in 2016, but are expected to grow to more than 70,000 in 2026, says Navigant Research. Regulations require commercial trucks to be sidelined if their windshields are cracked in a way that could affect the driver's view.

"I think the electrification of large trucks makes sense", Wheaton said in a statement shared with Newsweek.
