Tesla Semi production specs: powertrain, battery, Megacharger output, and more
The Tesla Semi has already been delivered to its first customers, but the actual production specs of the vehicle remain largely unknown or unconfirmed at best. Fortunately, a recent trip to PepsiCo’s Frito Lay facility in Modesto, Caifornia has provided some details that otherwise reveal the Tesla Semi production specs.
When Tesla held the first deliveries of the Semi, CEO Elon Musk highlighted that sustainable long-haulers are needed because in the transportation sector, semi trucks comprise about just 1% of vehicles on the road but they account for 20% of the emissions. Vehicles like the Tesla Semi are then designed to challenge this status quo.
Automotive publication MotorTrend was able to visit PepsiCo’s Modesto Frito Lay facility to check out the company’s first Tesla Semi units. As noted by the publication, the Modesto facility is a perfect fit for the Semi as the site already uses other green vehicles like BYD 8Y yard tractors, Peterbilt 220EV electric box trucks, and natural-gas-powered Volvo VNL trucks. The Tesla Semi fleet is used for out-and-back trips across the region.
The publication was able to gather some details about the Class 8 all-electric truck from its drivers and Tesla representatives who were at the location during the visit. Following are some key specs of the Tesla Semi.
Powertrain
The Tesla Semi features a modified Plaid tri-motor powertrain that’s spun backward. The Model S’ front motor drives the Semi’s rear axle and acts as the vehicle’s high-efficiency “highway drive unit.” The Model S Plaid’s dual rear motors, on the other hand, are installed on the rear axle. With this in mind, MotorTrend estimated that the Tesla Semi likely matches the Model S and Model X Plaid’s 1,020 horsepower and 1,050 pounds-feet of torque.
This estimate makes sense considering that a Tesla representative reportedly noted that the Tesla Semi makes “three times the power of an average diesel semi.” The US’ best-selling semi is the Freightliner Cascadia, whose base model features 350 horsepower. Three times the base Cascadia’s horsepower certainly aligns with the estimate that the Semi has about 1,020 horsepower. On a side note, the Tesla Semi production version does not have a frunk, unlike the vehicle’s prototype units.
Battery
Drivers of the Tesla Semi reportedly noted that the all-electric Class 8 truck is fitted with a 1,000 kWh battery pack. Tesla lists the Semi’s range as 500 miles per charge, and Elon Musk has also highlighted that the vehicle would consume only 2 kW per mile traveled.
If these estimates prove accurate, then the Semi’s 300-mile variant would likely have a battery pack that’s around 600 kWh. That’s still a lot of batteries, so Tesla would have to ensure that its production is optimized to ensure that the Semi is profitable.
Megacharger Output
The Tesla Semi features a charging port that’s different from all the vehicles that the company has released so far. The motoring publication noted that the Tesla Semi’s Megachargers installed on the Modesto facility could provide around 750 kW of power, or about three times the output of the company’s Supercharger V3 network.
The cables for the Tesla Semi’s Megachargers are thick, though they are reportedly easy to manage compared to some DC fast charging networks in the market. Charging the Semi from almost empty to 70% typically takes about 30 minutes. A full charge all the way to 100% reportedly takes around 90 minutes.
Physical Controls
While the Tesla Semi’s controls are mostly centered on its two infotainment systems, the vehicle also sports several physical buttons. Among these are the parking brake, trailer-brake air supply, and the vehicle’s hazards. Other physical controls include stalks similar to those found in the Tesla Model 3 and Model Y, though some buttons on the steering wheel resemble those in the new Model S and Model X.
Interior Space
The cabin of the Tesla Semi is cavernous, similar to the company’s other vehicles. MotorTrend noted that there’s enough space to enable a six-foot person to walk around and stretch in the Tesla Semi’s 3×7 foot cabin. So far, PepsiCo’s drivers seem to like the Semi, with some telling the motoring publication that the all-electric truck was very comfortable and “drove like a car.”
Other Details
The use of the Tesla Semi’s dual infotainment systems is quite interesting. The right display functions as the Tesla Semi’s main infotainment unit, while the left display exclusively shows pertinent information about the truck, such as its tire pressure. The windows in the Semi’s cabin also open when needed, though they do not roll down. Some space in the cabin also seem to be reserved for customers who wish to order the Tesla Semi with a sleeper cabin. Images taken of the Semi’s displays also confirm that the vehicle is equipped with Tesla’s Full Self-Driving computer.

Judge clears path for Elon Musk’s OpenAI lawsuit to go before a jury
The decision maintains Musk’s claims that OpenAI’s shift toward a for-profit structure violated early assurances made to him as a co-founder.
A U.S. judge has ruled that Elon Musk’s lawsuit accusing OpenAI of abandoning its founding nonprofit mission can proceed to a jury trial.
The decision maintains Musk’s claims that OpenAI’s shift toward a for-profit structure violated early assurances made to him as a co-founder. These claims are directly opposed by OpenAI.
Judge says disputed facts warrant a trial
At a hearing in Oakland, U.S. District Judge Yvonne Gonzalez Rogers stated that there was “plenty of evidence” suggesting that OpenAI leaders had promised that the organization’s original nonprofit structure would be maintained. She ruled that those disputed facts should be evaluated by a jury at a trial in March rather than decided by the court at this stage, as noted in a Reuters report.
Musk helped co-found OpenAI in 2015 but left the organization in 2018. In his lawsuit, he argued that he contributed roughly $38 million, or about 60% of OpenAI’s early funding, based on assurances that the company would remain a nonprofit dedicated to the public benefit. He is seeking unspecified monetary damages tied to what he describes as “ill-gotten gains.”
OpenAI, however, has repeatedly rejected Musk’s allegations. The company has stated that Musk’s claims were baseless and part of a pattern of harassment.
Rivalries and Microsoft ties
The case unfolds against the backdrop of intensifying competition in generative artificial intelligence. Musk now runs xAI, whose Grok chatbot competes directly with OpenAI’s flagship ChatGPT. OpenAI has argued that Musk is a frustrated commercial rival who is simply attempting to slow down a market leader.
The lawsuit also names Microsoft as a defendant, citing its multibillion-dollar partnerships with OpenAI. Microsoft has urged the court to dismiss the claims against it, arguing there is no evidence it aided or abetted any alleged misconduct. Lawyers for OpenAI have also pushed for the case to be thrown out, claiming that Musk failed to show sufficient factual basis for claims such as fraud and breach of contract.
Judge Gonzalez Rogers, however, declined to end the case at this stage, noting that a jury would also need to consider whether Musk filed the lawsuit within the applicable statute of limitations. Still, the dispute between Elon Musk and OpenAI is now headed for a high-profile jury trial in the coming months.

Tesla Giga Shanghai celebrates 5 million electric drive unit milestone
The milestone was celebrated by the company in a post on its official Weibo account.
Tesla China has reached another manufacturing milestone at Gigafactory Shanghai, rolling out the facility’s 5 millionth locally produced drive unit.
The milestone was celebrated by the company in a post on its official Weibo account. In its post, the Giga Shanghai team could be seen posing with the 5 millionth drive unit.
Giga Shanghai’s major benchmark
The milestone drive unit was produced at Gigafactory Shanghai, which produces the Model Y and the Model 3. In a release, Tesla China noted that its three-in-one integrated electric drive system combines the motor, gearbox, and inverter into a single compact assembly. This forms a powerful “heart” for the company’s electric cars.
Tesla China also noted that its drive units’ integrated design improves energy conversion efficiency while reducing overall weight and complexity, benefits that translate into stronger performance, improved handling, and longer service life for its vehicles.
The new milestone builds on earlier achievements at the same site. In July 2024, Tesla announced that its 10 millionth electric drive system globally had rolled off the line at the Shanghai plant, making it the first self-produced Tesla component to reach that volume.
More recently, the factory also produced its 4 millionth China-made vehicle, a Model Y L. The factory has also continued hitting global production milestones, rolling out Tesla’s 9 millionth EV worldwide late last year, with the landmark vehicle being a Tesla Model Y.
Tesla China’s role
Construction of Giga Shanghai began in January 2019, with production starting by the end of that year. This made it the first wholly foreign-owned automotive manufacturing project in China. The facility began delivering Model 3 vehicles locally in early 2020 and added Model Y production in 2021. The plant is now capable of producing about 1 million vehicles annually.
Throughout 2025, Giga Shanghai delivered 851,732 vehicles, representing a 7.08% year-on-year decline, according to data compiled by CNEVPost. Even so, recent months showed renewed momentum.
In December alone, Tesla China recorded wholesale sales of 97,171 vehicles, including domestic deliveries and exports, making it the company’s second-best monthly total on record, per data from the China Passenger Car Association. Retail sales during December reached roughly 94,000 units, up about 13% year over year.
Tesla stock (NASDAQ: TSLA) just got a price target boost from its biggest bear, Gordon Johnson of GLJ Research, who raised his expected trading level to one that is 95 percent lower than its current trading level.
Johnson pushed his Tesla price target from $19.05 to $25.28 on Wednesday, while maintaining the ‘Sell’ rating that has been present on the stock for a long time. GLJ has largely been recognized as the biggest skeptic of Elon Musk’s company, being particularly critical of the automotive side of things.
Tesla has routinely been called out by Johnson for negative delivery growth, what he calls “weakening demand,” and price cuts that have occurred in past years, all pointing to them as desperate measures to sell its cars.
Johnson has also said that Tesla is extremely overvalued and is too reliant on regulatory credits for profitability. Other analysts on the bullish side recognize Tesla as a company that is bigger than just its automotive side.
Many believe it is a leader in autonomous driving, like Dan Ives of Wedbush, who believes Tesla will have a widely successful 2026, especially if it can come through on its targets and schedules for Robotaxi and Cybercab.
Justifying the price target this week, Johnson said that the revised valuation is based on “reality rather than narrative.” Tesla has been noted by other analysts and financial experts as a stock that trades on narrative, something Johnson obviously disagrees with.
Dan Nathan, a notorious skeptic of the stock, turned bullish late last year, recognizing the company’s shares trade on “technicals and sentiment.” He said, “From a trading perspective, it looks very interesting.”
Tesla bear turns bullish for two reasons as stock continues boost
Johnson has remained very consistent with this sentiment regarding Tesla and his beliefs regarding its true valuation, and has never shied away from putting his true thoughts out there.
Tesla shares closed at $431.40 today, about 95 percent above where Johnson’s new price target lies.
