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.

Tesla ramps production of its ‘new’ models at Giga Texas
The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer.

Tesla is ramping up production of its ‘new’ Model Y Standard at Gigafactory Texas just over a week after it first announced the vehicle on October 7.
Earlier this month, Tesla launched the Tesla Model 3 and Model Y “Standard,” their release of what it calls its affordable models. They are priced under $40,000, and although there was some noise surrounding the skepticism that they’re actually “affordable,” it appears things have been moving in the right direction.
The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer:
News: the @Tesla Model Y Standard production is well underway at Giga Texas today!
This consistent with what I was told to expect during the unveiling day last week!
The outbound lot had many Premium Model Y’s and @cybertruck too!
More coming soon! pic.twitter.com/WU489QKPLB

The new Standard Tesla models are technically the company’s response to losing the $7,500 EV tax credit, which significantly impacts any company manufacturing electric vehicles.
However, it seems the loss of the credit is impacting others much more than it is Tesla.
As General Motors and Ford are scaling back their EV efforts because it is beginning to hurt their checkbooks, Tesla is moving forward with its roadmap to catalyze annual growth from a delivery perspective. While GM, Ford, and Stellantis are all known for their vehicles, Tesla is known for its prowess as a car company, an AI company, and a Robotics entity.
Elon Musk was right all along about Tesla’s rivals and EV subsidies
Tesla should have other vehicles coming in the next few years, especially as the Cybercab is evidently moving along with its preliminary processes, like crash testing and overall operational assessment.
It has been spotted at the Fremont Factory several times over the past couple of weeks, hinting that the vehicle could begin production sometime next year.

Tesla set to be impacted greatly in one of its strongest markets

Tesla could be greatly impacted in one of its strongest markets as the government is ready to eliminate a main subsidy for electric vehicles over the next two years.
In Norway, EV concentrations are among the strongest in the world, with over 98 percent of all new cars sold in September being electric powertrains. This has been a long-standing trend in the Nordic region, as countries like Iceland and Sweden are also highly inclined to buy EVs.
However, the Norwegian government is ready to abandon a subsidy program it has in place, as it has effectively achieved what it set out to do: turn consumers to sustainability.
This week, Norway’s Finance Minister, Jens Stoltenberg, said it is time to consider phasing out the benefits that are given to those consumers who choose to buy an EV.
Stoltenberg said this week (via Reuters):
“We have had a goal that all new passenger cars should be electric by 2025, and … we can say that the goal has been achieved. Therefore, the time is ripe to phase out the benefits.”
EV subsidies in Norway include reduced value-added tax (VAT) on cheaper models, lower road and toll fees, and even free parking in some areas.
The government also launched programs that would reduce taxes for companies and fleets. Individuals are also exempt from the annual circulation tax and fuel-related taxes.
In 2026, changes will already be made. Norway will lower its EV tax exemption to any vehicle priced at over 300,000 crowns ($29,789.40), down from the current 500,000, which equates to about $49,500.
This would eliminate each of the Tesla Model Y’s trim levels from tax exemption status. In 2027, the VAT exemptions will be completely removed. Not a single EV on the market will be able to help owners escape from tax-exempt status.
There is some pushback on the potential loss of subsidies and benefits, and some groups believe that the loss of the programs will regress the progress EVs have made.
Christina Bu, head of the Norwegian EV Association, said:
“I worry that sudden and major changes will make more people choose fossil-fuel cars again, and I think everyone agrees that we don’t want to go back there.”

Elon Musk was right all along about Tesla’s rivals and EV subsidies

With the loss of the $7,500 Electric Vehicle Tax Credit, it looks as if Tesla CEO Elon Musk was right all along.
As the tax credit’s loss starts to take effect, car companies that have long relied on the $7,500 credit to create sales for themselves are starting to adjust their strategies for sales and their overall transition to electrification.
On Tuesday, General Motors announced it would include a $1.6 billion charge in its upcoming quarterly earnings results from its EV investments.
Ford said in late September that it expects demand for its EVs to be cut in half. Stellantis is abandoning its plan to have only EVs being produced in Europe by 2030, and Chrysler, a brand under the Stellantis umbrella, is bailing on lofty EV sales targets here in the U.S.
How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies
The tax credit and EV subsidies have achieved what many of us believed they were doing: masking car companies from the truth about their EV demand. Simply put, their products are not priced attractively enough for what they offer, and there is no true advantage to buying EVs developed by legacy companies.
These tax credits have helped companies simply compete with Tesla, nothing more and nothing less. Without them, their products likely would not have done as well as they have. That’s why these companies are now suddenly backtracking.
It’s something Elon Musk has said all along.
Back in January, during the Q4 and Full Year 2024 Earnings Call, Musk said:
“I think it would be devastating for our competitors and for Tesla slightly. But, long term, it probably actually helps Tesla, that would be my guess.”
In July of last year, Musk said on X:
“Take away all the subsidies. It will only help Tesla.”
Take away the subsidies. It will only help Tesla.
Also, remove subsidies from all industries!

Over the past few years, Tesla has started to lose its market share in the U.S., mostly because more companies have entered the EV manufacturing market and more models are being offered.
Nobody has been able to make a sizeable dent in what Tesla has done, and although its market share has gotten smaller, it still holds nearly half of all EV sales in the U.S.
Tesla’s EV Market Share in the U.S. By Year
-
- 2020 – 79%
- 2021 – 72%
- 2022 – 62%
- 2023 – 55%
- 2024 – 49%
As others are adjusting to what they believe will be tempered demand for their EVs, Tesla has just reported its strongest quarter in company history, with just shy of half a million deliveries.
Will Tesla thrive without the EV tax credit? Five reasons why they might
Although Tesla benefited from the EV tax credit, particularly last quarter, some believe it will have a small impact since it has been lost. The company has many other focuses, with its main priority appearing to be autonomy and AI.
One thing is for sure: Musk was right.
