How much does the Tesla Semi weigh? Tesla Semi is the electric truck that can deliver up to 800km range, at least according to what Tesla said; recently the Tesla Semi has returned to the limelight following a tweet by Elon Musk who confirmed the possibility of making an entire 800 km journey with a total weight of almost 37 tons – unfortunately, however, we do not know how much the Semi weighs by itself, so this information leaves the time it finds.
How Much Does the Tesla Semi Weigh?
A typical class 8 diesel truck weights about 17,000 lbs. There is about 2,100 lbs. of fuel. A Tesla can start at 17,000 lbs. just for the truck. Then add 10,000 for the battery. This is 27,000 lbs. for the truck. Take off 19,000, and you are about -8,000 lbs. compared to a typical diesel.
With laws for EV semi at another 2,000 lbs. and less weight from the drive train and electric motor, you have a load deficit between 4,000 and 6,000 lbs. The total weight of the Tesla Semi seems to be about 27,000 plus tires and other parts, which could put it around 30,000 total miles.
Tesla Semi Battery, Drive, and Range
Battery Capacity
The Tesla Semi has a battery capacity of 500 miles * 1.7 kWh which equals about an 850 kWh battery. The 1.7 kWh comes from Elon Musk making a statement on Twitter.
Tesla did a 500 mile range test with its Tesla Semi. It started at 97% and ended with 4%, using 93% of the total battery. 500 miles * 1.7 kWh/0.93 = 914 kWh. It seems the battery capacity is somewhere between 850 kWh and 914 kWh.
500-Mile Drive
When looking at the video of the Tesla Semi driving, it looks like 14.2 seconds were at 60 miles per hour or greater. Regen braking was also minimal. There was a total time of 95 seconds real time at over 60 miles per hour, taking out bathroom breaks. The total time greater than or equal to 60 miles per hour was about 15%. Most of the driving is below 60 miles per hour.
Estimated Range
We see the best case at 60 miles per hour using about 800 kWh. At 55 miles per hour, this is about 740 kWh and more efficient. A more realistic speed is 52.5 miles per hour.
Aero drag puts the vehicle at about 780 kWh. If the vehicle were to go 70 miles per hour on a drive, that would require 1187 kWh for 500 miles, but could take the semi at about 358 miles of range at 70 miles per hour.
Tesla Semi Battery Weight, Load Capacity
Battery Weight
The battery weight of a 2022 Model is about 537 kg. It has a specific Energy of 186 wh/kg. That’s a total battery size of 100 kWh.
The Tesla Semi assumes an 850 kWh battery. Divide that by 0.186 wh/kg (using the Model S specs), which gives you, 4570 kg or 10,000 lbs. The battery is about 10,000 lbs. or less.
Carrying Capacity
The Tesla Semi has a total cargo weight of about 44,000 lbs. The typical max load is between 40,000 to 54,000 lbs.
How much weight are most diesel trucks hauling around? It looks like the distribution is between about 37,000 to 72,800 for about 80% of diesel trucks. This is within the range that the Tesla Semi could carry.
What we don’t know about the Tesla Semi?
One of the major unanswered questions is the price tag for this vehicle. Tesla has already made deliveries of its first Semis. However, the company hasn’t publicly announced a sales price yet.
The vehicles were initially listed for $180,000, but the price tag may have changed since the Semi’s original unveiling. Of course, potential buyers of the Semi will need to know this critical piece of information before placing an order.
The total weight of the Semi is also under speculation. Tesla’s website says the Semi is ‘fully loaded’ at 82,000 pounds. That 82,000-pound mark is the upper legal limit of what an electric semi truck can weigh on public roads. The question lies in how much the truck itself weighs.
After all, the weight of a load will vary dramatically. For example, a load of potato chips will weigh significantly less than a load of bottled water.
A key issue for truck operators is how much of the total weight limit is already claimed by this battery-powered truck. Hopefully, the truck’s weight details will be released in the coming months.
Future challenges
As fleet operators consider fully electric trucks, charging stations might delay the transition. Most utility companies don’t have the appropriate grid installed to charge dozens of these powerful trucks.
Furthermore, electric trucks will likely need access to power sources while on the move. According to a study by National Grid, electrifying highway gas stations to meet the power needs of these big trucks could require a similar amount of power as a small town in 2035.
It will take significant planning and work on our country’s electric grids to make the transition to electric power feasible for big trucks on a large scale.
How to invest in Emerging Technology
Tesla’s ability to make a road-ready fully electric truck is a big step forward toward a greener trucking future. The specs of this electric big rig are impressive, but they might improve over time as technology advances.
Innovations in technology transform the physical world around us. Savvy investors are always looking for ways to bring this potentially lucrative investment opportunity into their portfolios. Investing in Tesla might be one option investors consider.
It’s easier said than done to stay up to date on all of the emerging tech and translate that into profitable investments. Even those who like to stay current might find it challenging to incorporate the new information into their investment strategy.
The good news is that you don’t have to monitor the news constantly. Instead, you can get a helping hand from artificial intelligence (AI) to make appropriate adjustments to your portfolio.

FAQs
How much will a Tesla Semi truck cost?
During the Semi’s unveiling in late 2017, Tesla estimated that the truck’s 300-mile version would cost $150,000 and its 500-mile variant would cost $180,000.
How much does an unloaded Tesla Semi weigh?
If these estimates are accurate, it would suggest that the Semi was pulling a load of about 44,000 pounds during its 500-mile trip. If one were to consider the weight of the empty 53-foot trailer and Musk’s 81,000-pound total weight comment, it would suggest that the Tesla Semi weighs about 27,000 pounds on its own.
What is the max weight for Tesla Semi?
Per Tesla’s website, the Semi is capable of moving under its own power while clocking in at 82,000 pounds gross combination weight.
Above is information about How much does the Tesla Semi weigh? that we have compiled. Hopefully, through the above content, you have a more detailed understanding of Tesla Semi Battery, Drive, and Range. Thank you for reading our post.
