The new model is set to begin production in 2020 and will cost $200,000.
Without a trailer, the Tesla Semi goes from zero to 60 miles per hour in five seconds, compared to 15 seconds in a comparable diesel truck, Tesla said, and does zero to 60 miles per hour in 20 seconds with a full 80,000-pound load.
Tesla hasn't released any details about the semi.
Of course, the Model 3 loomed over it all.
Tesla's selling points include cheaper per-mile transport costs, safety, comfort, and (let's be honest) the cool factor.
Both vehicles are fast: The Roadster can take itself from zero to 60 miles per hour in 1.9 seconds, and the Semi can perform the same feat in five seconds (unburdened by a trailer), Tesla says.
For one, it's unclear if Tesla will actually get the Semi rolling out by 2019 as promised.
While Musk suggested that the Tesla Semi could effectively replace all diesel trucks, the haulage companies themselves are being a little more tentative in their expectations. These are business people not fans, and they will need convinced that this truck is better for their balance sheet than existing technology.
Semi adds one more major project on the plate of Musk, who not only has several in the works at Tesla, but also runs aerospace company Space X, and The Boring Company, which is attempting to solve traffic woes by creating a high-speed transportation system featuring a series of tunnels.
Now Tesla just needs to build these vehicles. "Every truck we sell has autopilot as standard", said Musk.
He noted that engine maker Cummins, German auto giant Daimler and commercial truck company Navistar are all working on their own electric trucks.
The tech CEO also says it's easier and safer to drive.
This is a landmark moment for cars because the Tesla Roadster, previous deemed overpriced and relatively less exotic - is suddenly a bargain at ₹1.3 crore since it out accelerates the likes of a Koenigsegg Agera S, and the ₹13 crore Bugatti Chiron. These are just concept vehicles, really, but it's Tesla, and nothing is really ever as it seems. "Diesel fuel is readily available and relatively efficient for heavy long-haul trucks that cruise open highways at a fixed speed".
"The specs on the new semi truck and sports auto would put both vehicles at the top of their segments ... assuming they can be produced and sold as part of a sustainable business plan", Brauer told Automotive News. "We believe electric trucks will be most beneficial on local and dray routes", John Roberts, president and chief executive officer at J.B. Hunt, explained of his company's reservations, "and we look forward to utilizing this new, sustainable technology". Regulations require commercial trucks to be sidelined if their windshields are cracked in a way that could affect the driver's view.
