Tesla Will Not Build Electric Buses

Not a Tesla App

Over the weekend, Elon Musk commented on a post about electric buses in Norway – and confirmed that Tesla doesn’t intend to build electric buses.

Let’s examine the context of the comment and then see what we know about Tesla’s future plans.

Norwegian Electric Buses

Norway launched a set of electric buses last year, which struggled to perform their routes in the cold winters. As many know, EVs tend to lose range at colder temperatures as some energy is used to keep the battery warm. Some of this energy use can be offset by preconditioning the battery and the cabin and using bigger batteries in colder regions.

These Norwegian buses, the Urbino series built by Solaris, have batteries that are too small to operate on the routes planned by Norway’s transport services in the winter. Heating the massive cabins takes too much energy, which isn’t too big of a surprise.

What’s most interesting is that these Solaris buses are heated with a heat pump—which is still hyper-efficient. Sadly, the battery is just too small, and Norway’s transport services didn’t account for the loss in efficiency in the winter months. Depending on ambient temperatures and the exact route, that could be anywhere from a 5% to a 30% reduction in range.

Instead, Norway intends to install mini diesel generators to power the cabin heating – thereby making these buses into hybrids rather than pure EVs. This is an interesting move – especially as Norway is a leader in the EV transition, with a 92% pure EV market share for new vehicles.

Tesla and Electric Buses

Elon’s confirmation that EV buses aren’t needed comes on the heels of some other super-important statements. He confirms that Teslas – in particular – can handle operating well even above the Arctic Circle. This is especially true after the Cybertruck Arctic Expedition where two Cybertrucks traveled all the way to the Arctic Ocean.

What’s key here is that Elon is implying that when Tesla rolls out Unsupervised FSD, there won’t be a need for buses. Instead, people needing a transportation option in urban areas can look forward to using a Robotaxi to get around in warmth. He has previously mentioned that we can expect the price of a Robotaxi fare to rival the cost of a bus ticket.

While traditional taxis are less efficient pound-for-pound in transporting people and reducing traffic, Robotaxis on the other hand have the option to reduce traffic by intelligently speaking to the fleet, analyzing traffic patterns, and autonomously adjusting their routes to best fit the destination.

Tesla also didn’t have anything nearly bus-shaped in their investor decks, so this seems to be in-line with their long-term goals. We can likely expect a commercial van though, so there’s plenty to look forward to.

All in all, Tesla won’t need an EV bus – instead, they’ll just produce a few more Robotaxis to make sure one is available to pick up passengers. Speaking of Robotaxi – the event is coming up very soon! We just saw a camouflaged prototype, and sign-ups for the Robotaxi Event draw just ended.

Tesla Update 2025.20 Tear Down Reveals Grok Personalities and Icons

@greentheonly on X

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.

The new line in the Energy App

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.

NHTSA to Streamline Approvals for Control-Free Vehicles Like Tesla’s Cybercab

Not a Tesla App

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.
