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 rival’s CEO makes shock suggestion to customers about Model Y

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

Tesla rival Xiaomi is experiencing demand that is off-the-charts with its new YU7 crossover, which competes with the Model Y. The company’s CEO has stated that demand is truly outpacing what it can build, and that customers in limbo should consider the Model Y because “it’s a great car.”

The Xiaomi YU7 has already gained an incredible number of orders so far. Its launch a few months ago had consumers busting down doors to place an order before others, and demand has been so high that customers will wait, on average, between 56 and 59 weeks for delivery.

Tesla Model Y meets new competition from Xiaomi 

Within 18 hours, Xiaomi received about 240,000 orders, CarScoops reported. Some customers are truly interested in the vehicle, but cannot wait the extended period to take delivery as they might need a car now.

Xiaomi CEO Lei Jun said on social meida that there are other cars out there that would be suitable as a replacement to the YU7:

“If you need to buy a car quickly, other China-produced new energy vehicles are pretty good.”

He explicitly mentioned the Model Y, Xpeng G7, and Li Auto i8.

Regarding the Model Y, he said:

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

The Model Y has been the best-selling car in the world over the past two years, and it still leads in many markets as the most sought-after EV. However, in China, there are so many formidable competitors that customers are seemingly going for whatever they can get to first.

Of course, a car is a car, but Tesla has gained a more notable reputation for its industry-leading tech and driver assistance systems, including City Autopilot, which has been used in China for a few months now.

Tesla offers tasty Supercharging incentive as Q3 push continues

Tesla is offering a tasty Supercharging incentive on inventory Model 3 units in Canada as it continues to push sales in the third quarter.

In the United States, Tesla is preparing for the end of the $7,500 electric vehicle tax credit. While it is offering a multitude of incentives in the U.S. to help push sales of its vehicles before the credit goes away, it is not saving the deals for Americans exclusively.

Yesterday, the company announced it is now offering Free Supercharging for life on all Model 3 inventory in Canada, a massive incentive for those who would use the vehicle as a daily driver:

The deal would normally only apply to Superchargers located in Canada, meaning if a Canadian drove over the border into the United States and Supercharged, they would have to pay for it.

However, Tesla also confirmed that the charging deal would extend to the U.S. Canadians will be able to drive across the U.S. and Supercharge for free for the life of the vehicle.

Free Supercharging is such a great perk because the money an owner saves on charging factors directly into what they are saving if they were to own a gas car. While Supercharging and home charging are, on average, cheaper than filling up with gas, the savings are not massive.

When Supercharging is free, it can save consumers hundreds of dollars per month, especially if they plan to use the Tesla for their daily commute. Some people could fill their gas cars up two times a week to get to work, spending $80-$100 every five days on gas.

Tesla has been using incentives like this to push vehicles into customers’ hands. Q3 could be one of the best three-month spans in recent memory with the push it is making.

Tesla is preparing to take on autonomy’s final boss

India’s city streets are notorious for their complexity and congestion.

If there is any sign that Tesla is now confident about its self-driving program, it would be this. As could be seen on Tesla’s Careers page, the company is now hiring Autopilot Vehicle Operators in Delhi and Mumbai, India. 

As far as real-world traffic is concerned, one could argue that India’s city streets are the final boss of autonomous driving systems due to their complexity and congestion.

Tesla job openings

As per Tesla in its recent job openings, Prototype Vehicle Operators will be responsible for driving an engineering vehicle for extended periods and conducting dynamic audio and camera data collection for testing and training purposes. In both its job listings for Mumbai and Delhi, Tesla noted that successful applicants will be gathering real-world data on the weekends and around the clock. 

Considering the job openings in India, Tesla seems to be intent on rolling out its advanced driver-assist systems like FSD in the country. This is quite interesting, as Tesla is not hiring Prototype Vehicle Operators in other territories that recently launched, such as the Philippines. Perhaps Tesla intends to tackle FSD’s final boss of sorts before rolling out FSD in other territories.

FSD’s rollout

Tesla’s autonomous driving program uses the company’s Full Self-Driving system, which is currently available on vehicles in North America and China. Tesla, however, has a more advanced version of FSD called Unsupervised FSD, which is currently being used in vehicles that are part of the Robotaxi pilot in Austin and the Bay Area.

Elon Musk has also recently announced on X that Tesla will be releasing FSD V14 in the coming weeks. He also shared a number of improvements that can be expected from FSD V14. “The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.
