As Tesla spreads its reach, it is becoming more and more evident that the next generation of vehicles in the market will be more like computers on wheels. GM, for its part, seems intent on ensuring that its Hummer EV will be one of these vehicles, with the veteran automaker recently revealing that the all-electric “super truck” will be using Unreal Engine to provide its “digital cockpit” with top-notch graphics.

The Hummer EV is expected to be unveiled this October 20 at 8 p.m. Eastern Time, and reports are abounding that the vehicle will be presented during the first game of baseball’s 2020 World Series. Interestingly enough, a press release from Epic Games, the company behind popular titles such as Fortnite, announced that the Hummer EV will be using Unreal Engine for its infotainment system.

Epic Games recently announced a new Human-Machine Interface (HMI) program that would enable the creation of automotive infotainment and digital cockpit systems. The Hummer EV will be the first vehicle in GM’s lineup that will be using this system for its “digital cockpit,” allowing the vehicle to feature graphics that are industry-leading and smooth. A short demonstration of the system in action was posted by Unreal Games on YouTube, and needless to say, the system is indeed very pleasing to the eye.

François Antoine, the Director of HMI and Embedded Systems at Epic Games, expressed his excitement about the system’s rollout to GM’s all-electric truck. “We have a dedicated team of artists and engineers who have been working to support new features for HMI. We’re thrilled that the GMC HUMMER EV will be the first vehicle to use Unreal Engine in its digital cockpit, marking an exciting partnership in building next-generation experiences on embedded systems,” Antoine said.

Scott Martin, the Creative Director of User Interface Design at GM, remarked that the automaker is excited to have the Hummer EV be the first vehicle to use Unreal Engine. “The use of Unreal Engine in the GMC HUMMER EV will provide richer graphics than ever before, celebrating the vehicle and its customers. We’re ecstatic to be the first vehicle to use Unreal Engine in our cockpit and look forward to sharing more details upon the vehicle’s reveal on October 20,” he said.

Needless to say, the Hummer EV’s digital cockpit will most definitely feature one of the best graphics in the market thanks to Unreal Engine. It would now be up to GM to ensure that its hardware is powerful enough so that the graphics platform does not go to waste. After all, it would be quite a shame if the Hummer EV ends up with a beautiful digital cockpit that does not perform at least as quickly or smoothly as Tesla’s infotainment system.

Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.

Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.

For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.

As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.

This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:

  • Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
  • Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
  • Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
  • Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
  • Santa Mode – New graphics, trees, and a lock chime
  • Light Show Update – Addition of Jingle Rush light show
  • Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
  • Navigation Improvements – Easier layout and setup
  • Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
  • Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
  • Phone Left Behind Chime – Your car will now tell you if you left a phone inside
  • Charge Limit Per Location – Set a charge limit for each location
  • ISS Docking Simulator –  New game
  • Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition

Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.

Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.

Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.

However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.

Powerwall discharge would be prioritized before tapping into the truck’s larger pack.

However, Tesla is still working on getting the feature out to owners, an email said:

“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. 

This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”

Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.

Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.

Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”

It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.

Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.

There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.

Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.

Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.

Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.

Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.

Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.
