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

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion
Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.

Tesla Roadster event gets delayed due to unfavorable weather
Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.
The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:
“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.
Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.
Tesla Roadster is available for order once again following brief hold
The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.
The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest
Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.
SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.
The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.
Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.
The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.
SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.
Starship’s 14th flight is set to launch on Monday, Sept 28. The 75-minute launch window opens at 7:15 a.m. CT. Live coverage of the mission starts ~35 minutes before launch → https://t.co/uQKQvgaTmJ
