Tesla revealed some new Semi fleet data, as well as a new feature the truck will have, and expanded on plans for infrastructure at the ACT Expo today in Los Angeles.

The Tesla Semi is one of the company’s most anticipated releases, and although it has already made its way into several company fleets, other companies are waiting for the automaker to fulfill their orders.

Tesla recently reaffirmed its mass production date of late 2025, hoping to build 50,000 Semi units annually at a new factory in Reno, Nevada.

At the ACT Expo, Tesla revealed some new details about the truck, including current fleet data, a new feature that will be a big selling point for many companies interested in the vehicle, and future infrastructure plans.

Fleet Data

Tesla has already accumulated over 7.9 million miles across its test fleet, the company said at the event. This includes 26 vehicles with over 100,000 miles on them, an impressive feat considering they are only taking regional runs, as of now.

The most notable companies with the vehicle are PepsiCo. and Frito Lay, both of which have spoken highly of the Semi’s ability to handle longer days. Drivers have reported that the Semi has helped them complete 1,000-mile travel days.

The first phase of production units will be integrated into Tesla’s logistics operations for real-world testing, which is something that has already been done.

Customer deliveries are expected to begin next year, something that was reiterated during the company’s most recent earnings call.

Tesla Semi’s New Feature

The semi will equip a 25-kilowatt electric Power Take-Off system that will help companies power auxiliary features like refrigeration, hydraulic systems, compressors, and more.

This is a massive feature, especially for companies that will be transporting perishable goods using the Semi. This will become especially important as it starts making cross-country runs and more companies begin taking delivery of the vehicle as production ramps up.

Expansion to Public and Private Charging Infrastructure

The Semi utilizes the Megacharger for its charging needs, and many sites have been installed already. Frito-Lay is expanding its Megacharger infrastructure by building eight new piles at its Bakersfield, California, factory.

We reported on that earlier this month:

However, Tesla has many more megawatt-level sites that are under construction for public Semi charging: 46, to be exact.

It also said it has more fleet sites that are underway, one of them being the Bakersfield factory’s infrastructure.

Tesla has officially released its Vehicle Safety Report, which shows data on the number of miles traveled between crashes for vehicles using and not using its Autopilot.

Tesla releases this data every quarter, and this quarter, it continued a somewhat consistent trend, revealing vehicles using Autopilot are 10 times less likely to be involved in crashes compared to the national average.

Even Teslas that are not using Autopilot are more than twice as safe as the U.S. average, which is tracked by the National Highway Traffic Safety Administration (NHTSA).

The company started releasing this data on a quarterly basis back in late 2018. Since its first release, in Q3 2018, the number of miles traveled between crashes has more than doubled.

Q1 2025 Safety Results

Tesla reported one crash for every 7.44 million miles driven in which drivers were using Autopilot technology. This is a far cry from the 3.35 million miles it first reported back in late 2018.

It is also a big improvement from the 5.94 million miles it recorded between accidents in Q4, but it is important to note that the last quarter of each year has shown to have lower numbers than others. This can mostly be attributed to weather conditions.

Tesla backtracked slightly compared to Q1 2024, when it recorded a crash once for every 7.63 million miles.

This past quarter, the company also saw one crash every 1.51 million miles for cars not using Autopilot technology. Even drivers that do not utilize Autopilot are seeing tremendous safety improvements compared to the national average, which was one crash every 702,000 miles.

This data was accumulated by both the NHTSA and the Federal Highway Administration (FHWA).

Tesla has emphasized safety since it started producing vehicles. Its Model S, Model 3, Model X, and Model Y have all achieved the lowest overall probability of injury of any cars tested by the New Car Assessment Program.

The company has used engineering improvements to push the probability of injury down.

Even the new Tesla Model Y, which started deliveries in the U.S. in March, has several new engineering features aimed at making the car safer for occupants and easier to repair in the event of a crash.

It’s interesting to see that even after Tesla successfully changed over Gigafactory Shanghai to the new Model Y, reports still emerged earlier this month suggesting that the demand for the revamped, all-electric crossover may already be over.

Videos from China, as well as the trend in Tesla’s new vehicle registrations, suggest that the demand for the new Model Y in the country is alive and well. 

Why Did Registrations Drop In April?

Arguments that the new Model Y was already running out of steam in China are partly based on the vehicle’s sudden drop in registrations in April. This, as well as the fact that Tesla China still estimates just 2-5 weeks of waiting time for new Model Y orders, was interpreted as a demand issue by Tesla skeptics.

What is quite surprising is that skeptics still seem to be intentionally ignoring the idea that Giga Shanghai allocates a lot of its vehicle output to foreign territories early on in the quarter. Thus, when Q1 ended and Q2 began, it only made sense that domestic vehicle registrations for the new Model Y dropped. One should not forget, after all, that Giga Shanghai supplies vehicles to numerous territories outside China.

Model Y Registrations and Delivery Centers

The new Model Y’s registrations are picking up once more in China, with numbers rising 77.5% in the week ending April 27. This suggests that Tesla China may be allocating more of Gigafactory Shanghai’s output to the domestic market once more. This also suggests that the new Model Y is seeing quite a bit of interest among Chinese consumers. The new Model Y, at least based on the trend of Tesla China’s registrations, definitely does not seem to be losing steam anytime soon.

A video that highlights this argument was shared recently on social media by Tesla China watcher @GeekLaii, who paid a visit to the company’s delivery center at Crab Island in Beijing. As could be seen in the video, the delivery center is packed with new Model Ys waiting for delivery. Consumers seem to be opting for the vehicle’s mid-tier variant as well, as the majority of the cars at the delivery center were comprised of new Model Y Long Range All Wheel Drive (AWD) variants.

Q1 Model Y Sales

In the first quarter, the Tesla Model Y was China’s best-selling SUV. That’s pretty impressive considering that the vehicle was limited to inventory units in the first months of the quarter. Despite this, the Model Y still sold 81,889 units in Q1 2025, putting it at the top of China’s SUV rankings. The new Model Y’s sales this Q2 might even be better.

Longtime Tesla investors have always argued that it is never wise to underestimate or bet against Elon Musk. At the same time, it is becoming evident that it is also not wise to underestimate or bet against Tesla’s best-selling car to date.
