Tesla Semi Unveiled: 500+ mile range, Bugatti-beating aero, 2019 production

Published

on

Tesla CEO Elon Musk unveiled the company’s highly anticipated semi-truck Thursday night on an airport hangar adjoining the company’s  Design Center in Hawthorne, CA. It’s the California-based electric car maker’s first foray into the commercial trucking industry.

Before a packed crowd of thousands, Musk revealed industry-disrupting details of the Tesla Semi.

The Tesla Semi can accelerate from 0-60 in 5 seconds, without cargo, and 20 seconds with a full 80,000 lb. load, more than twice as quick as a traditional diesel truck. The Semi can also traverse a 5% gradient at 65mph, compared to 45mph for diesel trucks. This is all powered by the truck’s four independent electric motors says Musk. “You can lose two of the four motors, and the truck will still keep going. In fact, even if you have only two of the four motors active it will still beat a diesel truck.”

In addition, the Tesla Semi has a .36 drag coefficient, compared to the standard of .65-.70. Musk compared it to a Bugatti, noting that the semi-truck beats the supercar’s .38 drag coefficient. “Overall, the Semi is more responsive, covers more miles than a diesel truck in the same amount of time, and more safely integrates with passenger car traffic,” says Tesla in its official announcement. The company also highlighted the fact that the Semi benefits tremendously from the regenerative braking that can recapture 98% of braking energy into the battery.

The Tesla Semi’s development has been led by Jerome Guillen, VP of Trucks and Programs. He has led the development of the truck since January 2016, and prior to his current role was VP of Worldwide Sales and Service and was the Model S’s Program Director & VP of Vehicle Engineering. While it may seem odd that Guillen jumped from Sales and Service to leading the development of an all-electric semi-truck, it’s worth noting that before joining Tesla, he was Director of Business Innovation at Daimler and General Manager of Freightliner (Large manufacturer of class 8 diesel semi-trucks, owned by Daimler).



Musk also pointed out that it takes 15 minutes for traditional diesel-powered semi-trucks to fuel up, where as a Tesla Semi can charge 400 miles in 30 minutes, which is provided by “Megachargers“. The Megachargers run on solar power and Tesla has guaranteed electricity rates of $0.07 per kWh with Semi owners.

The interior of the Tesla Semi has one seat positioned in the center and provides drivers with unparalleled  visibility. The seat is surrounded by two touchscreens that reminisce the ones found in the Model 3 sedan. Tesla’s semi-truck will also be equipped with Enhanced Autopilot which Musk notes will provide safety by automatically pulling over and stopping when truckers are in danger.

The Semi also has a small front truck, “because why not”, said Musk. The glass windshield on the Semi is thermonuclear resistant glass, which Musk says is a big deal because semi-trucks often have their windshields crack twice a year (which renders the truck undrivable). It can be assumed that this incredible glass could be related to Tesla’s nearly indestructible Solar Roof glass development.



Tesla claims that the semi will cost 20% less per mile compared to diesel trucks, costing $1.26/mile versus $1.51/mile . But that wasn’t all. Musk announced convoy technology that will further reduce the cost per mile driven for the Tesla Semi, even beating the cost of rail-based transportation.

“Tesla Semi can also travel in a convoy, where one or several Semi trucks will be able to autonomously follow a lead Semi.”

While Tesla didn’t unveil the price of the Semi, Musk noted that the semi-truck is expected to save operators $200k on fuel alone over 1 million miles. This resonated with fleet owners as Jerome Guillen pointed to some important guests at the event, stating that they had “placed a lot of reservations”. First production of the Tesla Semi is expected sometime in 2019.

Elon Musk says Tesla’s Roadster demo could be a bang, quite literally

Musk says tonight’s Roadster demo will be a banger, maybe literally. The clues add up.

Published

Elon Musk spent Wednesday and Thursday stacking teases on top of Tesla’s Roadster event, and the wording is getting harder to read as routine hype. Tesla streams the unveil tonight at 7:55 p.m. Central on X. Musk has called it “a candidate for greatest product demo of all time,” then added that “this demo will be a BANGER, probably metaphorically, though some chance literally.”

The “some chance literally” part is the line to watch. The Roadster has been tied to a SpaceX option package since 2018, and as we reported when the date was announced, the system is reportedly codenamed A71 and uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped car could reach 60 mph in about 1.1 seconds. Cold gas thrusters firing at full output are loud, and reports ahead of the event say the car will be unmanned with spectators kept several hundred yards back. A literal bang could simply mean a demonstration that sounds like one, though it is also an admission that something could go wrong on stage.

Then there is “Timing is everything,” which Musk posted a day earlier. Stocktwits noted that 7:55 p.m. is 19:55 on a 24 hour clock, which echoes 1955, the year Marty McFly travels to in Back to the Future. Musk has made that connection before. In 2019 he replied to an animation of a flying DeLorean by saying the new Roadster “will actually do something like this.” Nothing from Tesla confirms the movie reference, but the stream time was chosen by someone, and Tesla has not been shy about this kind of wink.

Also, Tesla said it moved the event because it “can only be held outdoors,” and Musk then wrote that the demo was postponed “due to high winds,” as Teslarati covered at the time. A car running a standing start in front of a crowd shrugs off wind. A car that leaves the ground does not. The venue near SpaceX’s McGregor test site and the FAA airspace closures reported around the original date point the same way, though we also noted the delay could be a plain safety precaution. Musk has also described the new Roadster as “beyond movies, beyond imagination, beyond human, yet still made by humans on Earth.”

The only official figures remain the 2017 ones: 620 miles of range, a top speed above 250 mph, a 1.9 second 0 to 60 time, and prices of $200,000 for the base car and $250,000 for the Founders Series. Production is expected at Giga Texas in 2027 or 2028. Tesla has said the event will cover pricing, specifications and production targets, and its livestream preview has the full rundown. Tesla reports third quarter earnings on October 21, so whatever lands tonight will be fresh going into that call. We will have live coverage as soon as the stream starts.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones

Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.

Published

Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”

He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”

That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.

SpaceX pitches subscription model for Trump’s Golden Dome

While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.

The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

Tesla opens the Q&A for its biggest earnings call yet

Tesla opens its Q3 earnings Q&A, and Cybercab, Robotaxi, Optimus and regulators loom over October 21.

Tesla has opened its shareholder question portal for the Q3 2026 earnings call, with the Say Q&A page already listing questions. Investors have until 4:00 p.m. EDT on October 20 to submit and vote on what management should answer.

The call is set for Wednesday, October 21. Tesla will post results after the market closes, with a live webcast at 4:30 p.m. CT, or 5:30 p.m. ET, through its investor relations site.

Say ranks questions by the number of shares behind the votes, which gives institutional holders extra weight over the retail crowd.

Ahead of Q2, retail investors asked why Robotaxi growth had stalled, when Cybercab would start customer rides, and where the Optimus Gen 3 ramp stood, while an institutional holder asked how Tesla and SpaceX would split Terafab duties. Cybercab has since answered one of those. Tesla said last week it has 300 plus Cybercabs serving Austin, up eightfold in 30 days, with Dallas named as the next city. The questions now are likely to move from when to how fast.

There is also a regulatory question hanging over the call. NHTSA has demanded sworn answers on how the pedal free Cybercab was certified against federal safety standards, with responses due October 30, nine days after the call. Whether an analyst raises it live is unknown, but it is the kind of exposure that tends to find its way into a Q&A.

The numbers will not be the main draw. Tesla already reported 486,532 deliveries and 13.7 GWh of storage for the quarter. Consensus sits around 43 to 45 cents per share on roughly $27.8 billion in revenue, according to Zacks, after a Q2 report that missed on EPS. Goldman Sachs, which holds a Neutral rating and a $360 target, argues the outlook for Robotaxi, FSD and Optimus will matter more to the stock than the quarter itself.

The call also lands six days after the rescheduled Roadster event, which Tesla will stream on X on Thursday, October 15, at 7:55 p.m. CT. If the Roadster shows up with a production date or a SpaceX thruster package, expect it to climb the voting list before the deadline.
