Tesla's next-gen vehicle may drastically reduce manufacturing costs
Not a Tesla App
A century ago, Henry Ford revolutionized automobile production by introducing the moving assembly line, a concept that changed manufacturing forever and made cars accessible to the masses. Today, we stand at the brink of another manufacturing revolution, this time led by Tesla. The company is reinventing the assembly line for the electric age with its forthcoming $25,000 car, also referred to as Redwood.
Unboxing the Future: Tesla's Modular Manufacturing
At the heart of Tesla's innovative production approach is the "unboxed" manufacturing system. This new method breaks from the century-old linear assembly process by adopting a modular, more flexible framework. Unlike traditional manufacturing lines where vehicles inch forward on a conveyor belt to have parts added sequentially, Tesla's unboxed system assembles cars in a manner reminiscent of assembling Lego blocks. Components are pieced together in dedicated subassembly areas, only coming together in the final stages.

This modular approach is not just about breaking away from tradition; it's a strategic move to outmaneuver stiff competition from Chinese EV startups, which benefit from robust government support and an efficient local supply chain. By adopting a method that echoes the assembly techniques of the consumer electronics industry, Tesla aims to reduce its manufacturing footprint by over 40%, promising faster and more cost-effective factory construction.
Robotic Precision and Reducing Costs
The unboxed system is set to dramatically lower vehicle production costs. Estimates suggest that manufacturing costs could be slashed by as much as 50%, enabling the construction of vehicles in significantly smaller factories. This efficiency is partly attributed to advanced robotics, like the Optimus Bot, which enhances operational efficiency and safety while providing unprecedented flexibility in manufacturing.
Tesla's introduction of the unboxed manufacturing system is not merely a technical evolution; it's a strategic adaptation designed to cement Tesla's position in a rapidly evolving automotive landscape. By drastically reducing costs and enhancing production efficiency, Tesla is not just aiming to compete with Chinese EV manufacturers but is also setting a new standard for vehicle production worldwide.
Embracing Manufacturing's Electric Future
Tesla's approach could serve as a blueprint for the future of manufacturing, challenging established norms and encouraging other industries to reconsider their own production methods. Just as Ford's assembly line became a hallmark of industrial manufacturing, Tesla's unboxed system may become synonymous with the next production era, characterized by flexibility, efficiency, and sustainability.
In essence, Tesla is doing for the electric vehicle what Henry Ford did for the gasoline car: making it accessible, affordable, and adaptable to the needs of the modern world. As we witness this new chapter in manufacturing history unfold, it's clear that Tesla's innovative spirit is not just about creating cutting-edge vehicles; it's also about reshaping automotive production for the 21st century.

While most automakers are adding basic and un-integrated AI assistants to their vehicles, Tesla appears to be working hand-in-hand with xAI to build out an entire cast of characters for in-vehicle Grok. In the latest dive into Tesla’s firmware, Tesla hacker @greentheonly uncovered a few new details about the upcoming Grok feature.
This discovery, part of a larger batch of changes found in Tesla update 2025.20, also offers a hint at the hardware required for the Grok.
A Dozen Groks
While we knew from previous firmware teardowns that Tesla was adding various Grok personalities to the vehicle UI, this update introduces a new one called Language Tutor, which may allow users to learn and practice a new language.
These are the different personas that will be included in Grok:
Argumentative
Assistant
Conspiracy
Doctor
Kids’ Stories
Kids’ Trivia Games
Meditation
Motivation
Romantic
Sexy
Storyteller
Therapist
Language Tutor
and the Grok Classic - Unhinged Mode
Release Date
Icons for these personalities have been added to the firmware for the first time, leading us to think Tesla is getting close to releasing the feature. However, even after the feature is developed and included in vehicle software, Tesla may only enable it selectively — such as for select employees for testing.
Grok is expected to be one of the largest vehicle features added via a software update, so it’ll be a big deal when it’s finally released. While we know more or less what to expect from Grok, what we don’t know is about vehicle requirements or whether it’ll require a subscription beyond Premium Connectivity.
Grok Requirements
While subscriptions required are anyone’s guess, vehicle requirements may be a little clearer now, thanks to Green’s discovery that Grok is only being added to AMD-based vehicle software builds.
Unfortunately, this likely means that older, Intel-based vehicles will not receive Grok support, at least for the time being. When Tesla introduced a voice assistant in China, they also started off with AMD-only support but later added Intel support, so it’s possible that the same could happen with Grok.
Energy Saving
Green also found a new undocumented navigation feature in 2025.20.3. This one focuses on leveraging Tesla’s vast amounts of data in an interesting way and offers drivers proactive advice to save energy on a well-traveled route.
In the Energy App, your vehicle will display, “This route is typically driven at X mph. Slow down by Y mph to save Z% for the rest of this trip.’
As you can see in the photo below, Tesla recognizes that vehicles typically drive at 66 mph on the route being driven and offers the driver the option to go five mph slower to save 1% of range. While this example doesn’t provide much incentive to slow down, it could be useful for someone with a low state of charge or if the savings are more significant.

Not a Tesla App
In the future, Tesla could even use this, alongside the road surface data they’re gathering, to help plan routes for Robotaxi and Unsupervised FSD.
In a letter to industry, the National Highway Traffic Safety Administration (NHTSA) has announced that it is overhauling its approvals process for vehicles designed without human controls.
The change addresses a regulatory bottleneck that has slowed down American companies like Tesla from deploying purpose-built Robotaxis, rather than relying on using traditional vehicles with steering wheels and pedals. The policy shift is outlined in a letter posted to the NHTSA’s website, which you can find here.
Reducing Approvals From Years to Months
Under the existing rules today, any vehicle that is built without a steering wheel or brake pedals must receive a special exemption from federal safety standards.
Obtaining exemptions for a particular vehicle was a time-consuming process for both the companies requesting exemptions and the NHTSA. The process was often a black box—nobody knew when an exemption might be granted, and approvals could take years.
The NHTSA, under the new administration’s guidelines for autonomous vehicle development, is now committed to streamlining this process. The agency will be implementing a new, faster approach immediately for receiving exemptions for autonomous vehicles without standard controls. The NHTSA expects decisions on exemption requests to be determined within months rather than years.
Accelerating the Cybercab
This change has massive implications for Tesla, which is banking on the production of the simplified and easy-to-maintain purpose-built Cybercab. The Cybercab is developed from the ground up as an autonomous Robotaxi and will be one of the key beneficiaries of this move by the NHTSA.
Knowing that a final design won't be caught in a multi-year regulatory limbo provides a level of certainty that has been missing. It allows Tesla to confidently plan the manufacturing, development, and deployment processes without worrying whether the project will get stuck in regulatory approvals.
According to the letter, the agency will publish its improved instructions for the streamlined process "shortly." With Tesla already having begun Cybercab pre-production and the goals for its deployment as soon as late 2026, there’s still a lot to be done to make autonomy a part of Tesla’s new sustainable abundance mission statement.
