Tesla Cybertruck will equip an 800-volt architecture when it begins deliveries on November 30, an announcement that is still fresh from the company’s Earnings Call earlier this week.

For EV newbies, the 800-volt architecture may not be much of a head-turner. However, to those who have been following the industry at all, 800v architectures are the way of the future for the EV industry, especially as more electric cars are on the road, charging times continue to be a concern to some, and heavier all-electric cars are becoming more available throughout the various automakers.

On Wednesday, Tesla confirmed what many believed for a long time: the Cybertruck would equip an 800-volt architecture.

What are the strengths of an 800-volt architecture? It comes down to charging times, efficiency, margins, and weight, all things that are important to the company and its products, as well as its financial status.

From a macro standpoint, Tesla’s financials are still strong. But Musk and Co. were not shy about warning investors and analysts about the upcoming economic headwinds it would encounter.

It’s a market-wide issue and not just a Tesla issue. As Tesla plans to launch the Cybertruck, interest rates are high, discouraging consumers from wanting to finance anything. Additionally, Musk confirmed it may take 18 months for the Cybertruck to be a positive cash flow contributor to Tesla’s financials.

The 800-volt architecture will improve margins on the vehicle instead of other EV architectures that may have been considered. It said explicitly in its Q3 Shareholder Deck:

“For very heavy vehicles, a high voltage powertrain architecture brings notable cost savings, which is why Cybertruck will adopt an 800-volt architecture.”

From a cost perspective, 800-volt architectures are void of as much copper throughout the vehicle, which reduces weight. Weight reductions improve performance and range.

Earlier today, we reported on the Cybertruck VIN Decoder, which was released by the NHTSA. It revealed the Cybertruck has two weight classifications:

“…the vehicle’s gross weight has two classes: G, which would be between 8,001 and 9,000 pounds, and H, which is between 9,001 and 10,000 pounds.”

800-volt architectures have greater efficiency because they allow electricity to move from the battery to the wheels with a lower current. This ultimately reduces the amount of power that is lost to heat, and higher voltage – lower current architectures can move the same amount of power with thinner wires, which relates to the reduction in copper that was mentioned previously.

800-volt architectures are big for the future of EVs, even outside of Teslas. Tesla EVs are far from the first cars on the market to equip an 800-volt architecture, as the Porsche Taycan had an 800v build back in 2018 when the German company unveiled the specs for its introductory EV.

Faster charging is the biggest advantage, as they can handle greater outputs from Superchargers. The V4 Supercharger from Tesla, for example, has a 350 kW output, enabled by increased amperage and current ratings.

This will keep EV owners at the Superchargers for less time, making charging more efficient and allowing more people to access chargers by decreasing congestion.

Tesla’s biggest rival in China reported a big profit decline once again

Published

Tesla’s biggest rival in China reported a big decline in its profitability for the second straight quarter, and a loss of one-third compared to the same quarter last year.

BYD overtook Tesla as the best-selling EV maker in China in the fourth quarter of 2023, finally surpassing the company in terms of sales in the region.

Is Tesla really losing to BYD, or just playing a different game?

The Chinese market is one of the most competitive in the world, especially for EVs, as the industry is healthy with young and scrappy companies looking to sell the best possible tech in their vehicles.

BYD reported its earnings on Thursday and said that its profit had slumped by 33 percent compared to the same quarter last year. For this year’s third quarter, BYD reported a net profit of 7.8 billion yuan ($1.1 billion), a 32.6 percent decrease compared to the same period in 2024.

Its revenue was 195 billion yuan ($27.4 billion), which was only a 3 percent decrease compared to Q3 2024.

The drop in profits and revenue can mostly be attributed to the ongoing growth of competition in the Chinese market. The increased competition in China has pushed companies to turn to overseas markets in response, according to CnEVPost.

BYD is one of those companies, and it is attempting to push sales upward by entering new markets, especially in Europe, where the company sold more than 13,000 units in EU countries in September alone.

This was a 272 percent increase year over year, a major piece of evidence that it has a lot of potential in foreign markets.

The drop in financial figures is likely a short-term issue for BYD, as it has already established itself as a formidable competitor to many companies in many markets. In Q1, it reported an increase in profit by 100 percent compared to the same time span the year prior.

As it works to expand to even more markets in the world, it will continue to build upon its already-solid reputation.

GM takes latest step to avoid disaster as EV efforts get derailed

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

General Motors has taken its latest step to avoid financial disaster as its electric vehicle efforts have been widely derailed.

GM’s electric vehicle manufacturing efforts started off hot, and CEO Mary Barra seemed to have a real hold on how the industry and consumers were starting to evolve toward sustainable powertrains. Even former President Joe Biden commended her as being a major force in the global transition to EVs.

However, the company’s plans have not gone as they’ve drawn them up. GM has reported some underwhelming delivery figures in recent quarters, and with the loss of the $7,500 tax credit, the company is planning for what is likely a substantial setback in its entire EV division.

Earlier this month, the company reported it would include a $1.6 billion charge in its quarterly earnings results from EV investments. It was the first true sign that things with GM’s EV projects were going to slow down.

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

This is in addition to the 280 employees it has already laid off after production cuts that happened earlier this year at the Detroit-Hamtramck plant.

After November 24, GM will bring back 3,200 people to work until January 5 to operate both shifts. On January 5, GM is expected to keep 1,200 workers on indefinite layoff.

GM is not the only legacy automaker to make a move like this, as Ford has also started to make a move that reflects a cautious tone regarding how far and how committed it can be to its EV efforts.

After the tax credit was lost, it seemed to be a game of who would be able to float their efforts longest without the government’s help. Tesla CEO Elon Musk long said that the loss of these subsidies would help the company and hurt its competitors, and so far, that is what we are seeing.

However, Tesla still has some things to figure out, including how its delivery numbers will be without the tax credit. Its best quarter came in Q3 as the credit was expiring, but Tesla did roll out some more affordable models after the turn of the quarter.

Tesla expands Robotaxi geofence, but not the garage

This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.

Tesla has expanded its Robotaxi geofence four times, once as recently as this week.

However, the company has seemingly kept its fleet size relatively small compared to the size of the service area, making some people — even pro-Tesla influencers — ask for more transparency and an expansion of the number of vehicles it has operating.

Over the past four months, Tesla has done an excellent job of maintaining growth with its service area in Austin as it continues to roll out the early stages of what is the Robotaxi platform.

The most recent expansion brought its size from 170 square miles (440.298 sq. km) to 243 square miles (629.367 sq. km).

This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.

Tesla has never revealed exactly how many Model Y vehicles it is using in Austin for its partially driverless ride-hailing service (We say partial because the Safety Monitor moves to the driver’s seat for freeway routes).

When it first launched Robotaxi, Tesla said it would be a small fleet size, between 10 and 20 vehicles. In late August, after its second expansion of the service area, it then said it “also increased the number of cars available by 50 percent.”

The problem is, nobody knows how many cars were in the fleet to begin with, so there’s no real concrete figure on how many Robotaxis were available.

This has caused some frustration for users, who have talked about the inability to get rides smoothly. As the geofence has gotten larger, there has only been one mentioned increase in the fleet.

Tesla did not reveal any new figures or expansion plans in terms of fleet size in the recent Q3 Earnings Call, but there is still a true frustration among many because the company will not reveal an exact figure.
