The Tesla Semi Is Finally Being Built at Scale
This article is based on reporting originally published by Yahoo Autos and The Autopian.
The Tesla Semi has been talked about for so long that it was easy to wonder when we'd actually start seeing more of them on the road. The truck was first unveiled in 2017 and was originally expected to enter production in 2019. A small number eventually made it into fleet operations, but mass production remained years away.
Now, that wait appears to be over.
Tesla has opened its first factory dedicated to the Semi in Sparks, Nevada. The facility is designed to eventually produce up to 50,000 trucks a year, although Tesla hasn't said how quickly it expects to reach that number. The first Semi came off the new production line in April and trucks are now going to customers including PepsiCo, DHL and US Foods.
The production truck also gives us a better idea of what Tesla is actually bringing to the Class 8 market. There are two versions: a Standard Range model rated for 325 miles and a Long Range model rated for 500 miles. Tesla says the truck uses about 1.7 kWh per mile and the Long Range version can travel even farther with a lighter load.
Charging is another big piece of the story. The Semi can use a 1.2-megawatt charging system that Tesla says can add about 60% of its range in 30 minutes. That's an enormous amount of power, but for a commercial truck, charging speed isn't just an impressive number. A truck that's sitting isn't moving freight, so how quickly fleets can get a Semi charged and back on the road will play a big role in where these trucks make sense.
There are already signs that the range claims can hold up in real operations. DHL previously tested a Semi loaded to about 75,000 pounds and drove it 388 miles on a single charge. Other fleets have also been testing the truck over the past few years, giving Tesla millions of miles of real-world data before moving into larger-scale production.
For drivers, the Semi is also very different from a conventional Class 8 truck. The driver sits in the center of the cab rather than on the left and regenerative braking handles much of the deceleration. The production version also includes electric power steering and an updated cabin. Early driving impressions have pointed to strong acceleration, a tight turning radius and a smooth ride while loaded.
Still, putting more trucks on the production line doesn't answer every question.
Charging infrastructure remains one of the biggest. Diesel trucks can fuel almost anywhere and long-haul operations routinely cover distances well beyond the Semi's current range. Tesla is building out its Megacharger network, but until that network becomes much larger, the Semi may be easier to fit into local and regional operations where trucks return to the same terminal or charging location.
Service will be another thing fleets watch closely. Tesla says it is developing a Semi-specific service and repair network, but operators will need to know how quickly a truck can get repaired when something goes wrong and how much maintenance can be handled outside Tesla's own network. In trucking, uptime can matter just as much as range.
Then there's cost. Electric Class 8 trucks generally require a much larger upfront investment than comparable diesel trucks, although fleets may recover some of that difference through lower fuel and maintenance expenses. With diesel prices currently high, those operating-cost calculations are getting even more attention.
The Tesla Semi isn't going to replace diesel trucks overnight. Long-haul range, charging infrastructure, service and cost are still real considerations for fleets deciding whether an electric Class 8 makes sense for their operation.
But after years of waiting, the Semi is finally moving beyond limited testing and into larger-scale production. That means truckers and fleets will soon have something much more useful than promises and specifications: more real trucks doing real work.
The real question now is—
if the range, charging and operating costs worked for your routes, would you consider putting an electric Semi to work in your operation?
