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 executive teases plan to further electrify supply chain
One of Tesla’s top executive hints at how Tesla is further electrifying its supply chain.

A high-level Tesla executive has said the company is working to further electrify its supply chain, following a successful road test with the Semi this week.
After Tesla supplier thyssenkrupp completed a successful 5,000-mile winter trial with the Semi this week, Dan Priestley, the company’s Director of Semi Engineering, noted on X that the demonstration is a part of larger efforts to electrify more of the supply chain. The executive said that the company is already working to help suppliers like thyssenkrupp implement the Semi into their operations, particularly due to its cost savings and reliability.
Following the thyssenkrupp demo, the supply chain company has also begun integrating the Semi into its fleet, and Priestley suggests that more are still to come:
Working with our suppliers and logistics partners to electrify Tesla’s supply chain. With lower cost and higher reliability, it just makes sense. thyssenkrupp pushed the truck hard over this demo and now plans to integrate Semi into their fleet.

Tesla Semi factory nears official production as trials continue to impress
Tesla’s early Semi trials received positive results from both thyssenkrup and ArcBest’s ABF Freight this week, with the latter company logging 4,494 miles during a pilot period, and averaging 321 miles per day despite a 7,200-foot climb over Donner Pass.
The company has also been constructing a factory for volume Semi production at its Gigafactory in Nevada, and in recent weeks, the plant is looking nearly complete. Semi frames have been spotted in increasing numbers outside the facility recently, suggesting that Tesla is nearing early production on site.
The company also hired more than 1,000 workers for the Semi factory in April, while the plant is eventually expected to produce as many as 50,000 Semi units annually.

Tesla Semi completes 5,000-mile winter trial with thyssenkrupp
The test covered nearly 5,000 miles in winter conditions.

thyssenkrupp Supply Chain Services has completed a three-week pilot of the Tesla Semi at one of its California logistics hubs, marking a new step in the company’s sustainability push. The test covered nearly 5,000 miles in winter conditions and focused on evaluating the electric Class 8 truck’s efficiency, transparency, and operational performance.
Tesla Semi offers efficiency gains and real-time logistics visibility
During the pilot, the Tesla Semi was used for active freight delivery, including routes over the Altamont Pass. thyssenkrupp evaluated the vehicle’s ability to reduce downtime, enhance delivery speed, and offer greater real-time supply chain visibility, the company noted in a press release.
Live diagnostics and performance monitoring allowed the logistics provider to track metrics such as speed, routes, and overall efficiency—data that supports smarter and more transparent logistics operations.
“The Tesla Semi aligns with our ongoing commitment to sustainability and operational excellence,” said Bob Denehy, Chief Commercial Officer at thyssenkrupp Supply Chain Services. “Its efficiency and diagnostic features, and low environmental impact make it a natural fit for our evolving logistics strategy.”
Pilot builds on long-term partnership with Tesla and green energy goals
A logistics partner to Tesla since 2015, thyssenkrupp Supply Chain Services was one of the first companies selected to test the Tesla Semi in a real-world setting. The trial reinforces the company’s push into renewable energy logistics and reflects its long-term goal of integrating alternative-fuel technologies across its operations.
Plans are now underway to begin adding electric Semis to its fleet as part of a wider emissions-reduction effort. The pilot is thus the latest example of how logistics providers are embracing next-generation transport technologies to meet environmental goals and enhance supply chain performance.

Tesla Semi shows strong results in ArcBest’s real-world freight trial
The truck handled varied terrain, including a 7,200-foot climb over Donner Pass.

ArcBest has successfully wrapped up a three-week pilot program testing a Class 8 Tesla Semi in over-the-road applications. The trial was conducted through ArcBest’s ABF Freight division, and it covered routes between Reno and Sacramento and regional operations around the Bay Area.
Tesla Semi pilot sees strong performance and positive driver feedback
The Tesla Semi logged 4,494 miles during the pilot, averaging 321 miles per day with an energy efficiency of 1.55 kWh per mile. The Tesla Semi handled varied terrain, including a 7,200-foot climb over Donner Pass, and delivered performance comparable to diesel counterparts.
Drivers who participated in the pilot also gave positive feedback to the Tesla Semi, citing the Class 8 all-electric truck’s comfort, safety, and visibility thanks to features like a center seating position and intuitive controls. Matt Godfrey, president of ABF Freight, shared his thoughts on the pilot in a press release.
“We’re not looking for a truck that performs well ‘for an EV.’ It must meet or exceed the performance and total cost of ownership targets of our most efficient diesel units. This pilot gives us great insight into the potential of EV semis in our operations,” he said.
ArcBest highlights need for more charging infrastructure
While the pilot met expectations, ArcBest noted that broader deployment of Class 8 all-electric trucks like the Tesla Semi will still depend on improvements in charging infrastructure. This way, longer-haul operations become more than feasible.
The pilot marks another step in ArcBest’s investment in sustainable logistics technologies. In addition to testing the Tesla Semi, the company operates a small fleet of EVs, including nine electric yard tractors, two electric forklifts, and two Class 6 electric straight trucks. Dennis Anderson, ArcBest chief innovation officer, noted that vehicles like the Tesla Semi are notable developments in the transportation sector.
“Freight transportation is a vital part of the global economy, and we know it also plays a significant role in overall greenhouse gas emissions. While the path to decarbonization presents complex challenges — such as infrastructure needs and alternative fuel development — it also opens the door to innovation. Vehicles like the Tesla Semi highlight the progress being made and expand the boundaries of what’s possible as we work toward a more sustainable future for freight,” he stated.
