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.

Nikola Motor founder Trevor Milton given full pardon by President Trump

Nikola Motor founder Trevor Milton has been given a full pardon by U.S. President Donald Trump in an unprecedented turn of events.
Trevor Milton Media announced late Thursday that the formerly jailed founder of the all-electric automaker that President Trump had “pledged to end the political weaponization of the Justice Department. This pardon marks a step toward fulfilling that commitment.”
Milton was sentenced to four years in prison in December 2023 after being found guilty of multiple counts of fraud.
Nikola founder Trevor Milton sentenced to four years in prison
“I was not a very seasoned CEO,” Milton said after his sentencing. Questions about the legitimacy of some Nikola product demonstrations and several statements that were found to be misleading regarding the company’s progress on its vehicles brought Milton to U.S. Federal Court to face two counts of wire fraud and one count of securities fraud.
Now, he is free.
Milton said in a statement:
“This pardon is not just about me—it’s about every American who has been railroaded by the government, and unfortunately, that’s a lot of people. It is no wonder why trust and confidence in the Justice Department has eroded to nothing. I wish judges would stop believing whatever the prosecutors feed them so Americans could trust the justice system again. Until that happens, our justice system will continue to erode until there is nothing left. The 90+% conviction rate in New York is appalling and is a result of prosecutors getting whatever they want and putting innocent people in prison. I saw firsthand the tactics they use to achieve those guaranteed convictions. I am incredibly grateful to President Trump for his courage in standing up for what is right and for granting me this sacred pardon of innocence.”
Milton will now launch a documentary that is available for preview here.

Tesla vandal who lit Las Vegas repair center on fire arrested

A vandal in Las Vegas who lit a Tesla repair center on fire has been arrested, bringing a name and face to the crime that engulfed vehicles and a structure in flames.
Officers in Las Vegas arrested Paul Kim, a 36-year-old, on Wednesday. He faces charges of arson and possessing an explosive device.
The Tesla repair center at 6260 West Badura Avenue was set aflame on March 18 at around 2:45 a.m. In total, five vehicles were set on fire, as well as the building itself. It was one of the more notable instances of vandalism against Tesla in recent months, but police now have their culprit.
Las Vegas Metro Police Department Sheriff Dori Koren described the weapons Kim used to execute the attack:
“He used what appeared to be multiple Molotov cocktails and firearms to conduct his attack.”
As the instances of attacks on Tesla continue to be publicized, we are now seeing considerable pushback from owners, the company, and even the United States government regarding what it calls “domestic terrorism.”
Owners are now filing lawsuits against those who vandalize their vehicles, as the first civil suit against a vandal was filed in Texas yesterday.
Great
— Elon Musk (@elonmusk) March 27, 2025
Tesla has not made any moves itself against the vandals, but we expect the company to potentially enter some litigation against groups or politicians that incite violence against its property and the owners of its vehicles.
Additionally, the U.S. government has utilized the FBI to probe incidents against Tesla as a part of them being constituted as instances of domestic terrorism. Earlier this month, the Bureau established a specific task force to handle Tesla-related attacks.
“The FBI has been investigating the increase in violent activity toward Tesla, and over the last few days, we have taken additional steps to crack down and coordinate our response,” FBI head Kash Patel said on X. “This is domestic terrorism. Those responsible will be pursued, caught, and brought to justice.”

Elon Musk clarifies Trump tariff effect on Tesla: “The cost impact is not trivial”
The U.S. President has stated that Elon Musk stayed silent and provided no input in the administration’s tariffs.

U.S. President Donald Trump’s plan to implement a 25% tariff on non-U.S.-made vehicles starting next week would affect American electric car maker Tesla.
This was confirmed by CEO Elon Musk in a recent post on social media platform X.
Musk and Trump
While Elon Musk works closely with the Trump administration due to his role in the Department of Government Efficiency (DOGE), the U.S. president has emphasized that the Tesla CEO never asks for favors. This was highlighted in his recent comments, when he stated that Elon Musk stayed silent and provided no input in the administration’s 25% auto tariffs.
When asked by reporters if the new tariffs would be good for Tesla, Trump noted that they may be “net neutral or they may be good.” The U.S. president also pointed to Tesla’s automotive plants in Fremont, California and Austin, Texas, which produce vehicles that are sold in the country. “Anybody that has plants in the United States — it’s going to be good for them,” Trump noted.
Tesla Affected
In a post on X, Elon Musk clarified that the Trump administration’s tariffs would affect the prices of vehicle parts that are sourced from other countries. This was a concern that Tesla previously outlined in a letter to the U.S. Trade Representative, which noted that even with “aggressive localization” of its supply chain, “certain parts and components are difficult or impossible to source within the United States.”
As per Musk in his recent post on X, the cost impact of the Trump administration’s tariffs is no joke. “To be clear, this will affect the price of parts in Tesla cars that come from other countries. The cost impact is not trivial,” Musk wrote in his post.
Potential Effects
Reactions to Musk’s comments from users of the social media platform were varied, with some speculating that the Trump auto tariffs could result in Teslas becoming more expensive in the United States. Despite this, the potential increases in Tesla’s vehicle prices might not be as notable as other cars, particularly those that are produced outside the country.
