Tesla Semi is the first of several vehicles to feature a thousand-volt powertrain
The Tesla Semi’s inaugural delivery event for PepsiCo featured a number of key announcements that are pertinent not only to the all-electric Class 8 truck but also to the company’s other vehicles. These include the Semi’s charging system, which will also be compatible with vehicles like the Cybertruck, as well as the vehicle’s immense power and efficiency.
As highlighted by CEO Elon Musk and Dan Priestley, a Senior Manager of Tesla Semi Truck Engineering, the all-electric Class 8 truck is a complete beast. It’s sleek, powerful, and with its 500-mile range, it’s more than capable of hauling a meaningful amount of cargo on a single charge. While discussing the Class 8 truck’s advantages, Musk and Priestley highlighted that the Semi is so powerful it has three times the power of any diesel truck on the road today. But that’s not all. The vehicle is also extremely efficient.
“You got three times the power than any diesel truck on the road right now. So you got all the power you need to get the job done. But the other reason that it’s a beast is because it’s also efficient. You can go 500 miles on a single change on one of these things. So it’s the mix of those two, that this is why it’s a game-changer. And what’s awesome is that both of those are enabled by our new thousand-volt powertrain, which is the first vehicle that we’re doing with that,” Priestley said.
The idea of Tesla adopting a thousand-volt powertrain came as a pleasant surprise to the EV community, especially since the company has been pretty tight-lipped about the details of its future projects. During the Q1 2022 earnings call, Tesla executives were asked if the company has plans to adopt an 800-volt architecture for its vehicles, similar to those used by rivals like the Porsche Taycan.
Back then, Tesla SVP of Powertrain and Energy Engineering Andrew Baglino explained that an 800-volt architecture doesn’t really make sense for small vehicles like the Model 3 or Model Y. The executive also noted that if Tesla does adopt such a system, it would be for larger vehicles like the Semi or the Cybertruck. Considering Musk and Priestly’s comments during the Semi’s unveiling, however, it appears that the Semi would only be the first of several vehicles that will feature a thousand-volt powertrain.
“Don’t worry, there will be some more vehicles coming with that. But this will be a game-changer because of all the awesome innovations that have happened behind the scenes and under the hood, so to speak,” Priestley said.

Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.

Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.
Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:
It’s coming soon
— Elon Musk (@elonmusk) July 21, 2026
Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.
Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.
Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.
The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.
Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.

Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.
