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 is ramping up hiring for positions related to the Roadster program, the company’s ultra-fast supercar that has been teased to potentially hover by CEO Elon Musk.

The company seems to be crossing off its last handful of things before it plans to unveil the vehicle on April Fool’s Day, just about four months away.

Tesla published three new positions for the Roadster this week, relating to Battery Manufacturing, General Manufacturing, and Vision Engineering. All three are located in Northern California, with two being at the Fremont Factory and the other at the company’s Engineering HQ in Palo Alto.

Technical Program Manager, Battery Manufacturing

Located in Fremont, this role specifically caters to the design of the Roadster to factory operations. It appears this role will mostly have to do with developing and engineering the Roadster’s battery pack and establishing the production processes for it:

“You will foster collaboration across design engineering, manufacturing, quality, facilities, and production to align with company priorities. Additionally, you will understand project opportunities, challenges, and dependencies; translate scattered information into concise, complete messages; and communicate them to every team member. As the business process development lead, you will develop, maintain, and implement tools and processes to accelerate battery manufacturing execution, achieve cross-functional alignment, and deliver highly efficient systems.”

Manufacturing Engineer, Roadster

Also located in Fremont, this role also has to deal with the concept development and launch of battery manufacturing equipment. Tesla says:

“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams.”

Manufacturing Vision Engineer, Battery Vision

This position is in Palo Alto at Tesla’s Engineering Headquarters, and requires the design and scale of advanced inspection and control systems to next-generation battery products:

“You’ll work on automation processes that directly improve battery performance, quality, and cost, collaborating with world-class engineers in a fast-paced, hands-on environment.”

Developing and deploying 2D and 3D vision and measurement systems from proof-of-concept to deployment on high-volume battery manufacturing lines is part of the job description.

Roadster Unveiling

Tesla plans to unveil the Roadster on April 1, and although it was planned for late this year, it is nice to see the company put out a definitive date.

Musk said on the Joe Rogan Experience Podcast in late October:

“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever.”

Production should begin between 12 to 18 months after unveiling, so we could see it sometime in 2027.

Tesla Full Self-Driving statistic impresses Wall Street firm: ‘Very close to unsupervised’

The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.

Tesla Full Self-Driving performance and statistics continue to impress everyone, from retail investors to Wall Street firms. However, one analyst believes Tesla’s driving suite is “very close” to achieving unsupervised self-driving.

On Tuesday, Piper Sandler analyst Alexander Potter said that Tesla’s recent launch of Full Self-Driving version 14 increased the number of miles traveled between interventions by a drastic margin, based on data compiled by a Full Self-Driving Community Tracker.

The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.

Interestingly, there was a slight dip in the miles traveled between interventions with the release of v14.2. Piper Sandler said investor interest in FSD has increased.

Full Self-Driving has displayed several improvements with v14, including the introduction of Arrival Options that allow specific parking situations to be chosen by the driver prior to arriving at the destination. Owners can choose from Street Parking, Parking Garages, Parking Lots, Chargers, and Driveways.

Additionally, the overall improvements in performance from v13 have been evident through smoother operation, fewer mistakes during routine operation, and a more refined decision-making process.

Early versions of v14 exhibited stuttering and brake stabbing, but Tesla did a great job of confronting the issue and eliminating it altogether with the release of v14.2.

Tesla CEO Elon Musk also recently stated that the current v14.2 FSD suite is also less restrictive with drivers looking at their phones, which has caused some controversy within the community.

Although we tested it and found there were fewer nudges by the driver monitoring system to push eyes back to the road, we still would not recommend it due to laws and regulations.

With that being said, FSD is improving significantly with each larger rollout, and Musk believes the final piece of the puzzle will be unveiled with FSD v14.3, which could come later this year or early in 2026.

Piper Sandler reaffirmed its $500 price target on Tesla shares, as well as its ‘Overweight’ rating.

Tesla has excluded FSD-purchased and subscribed vehicles that are utilizing Hardware 3, so it seems there is a strategy to this limited rollout.

Two Surprise Additions

Tesla has added two additional features with the Holiday Update, which include a new Storage Space for Dashcam feature that shows how much space you have used and remaining on your USB drive.

Additionally, Tesla gamified Supercharging with a new “Charging Passport” feature, which we reported on earlier today.
