Range Energy’s electric trailer, which allows fleets to effectively hybridize by adding a battery and motor to the trailer, has been put into service by Petaluma Egg Farm to improve efficiency of its diesel shipping fleet by 50-70%.

The concept behind Range Energy’s trailer is relatively simple. Instead of the diesel-engine tractor having to do all the work to pull the trailer, Range adds a battery and motor to the trailer to help it push its own weight forward, effectively cutting the amount of weight the diesel engine has to pull and therefore increasing efficiency.

It sounds like a bit of a hack, but the purpose behind it is that electric tractors are quite expensive and are still ramping up in production. Meanwhile, trucking companies already have working diesel tractors that could be expected to have many years of life left, and aren’t necessarily excited to scrap their expensive tractors for an expensive new electric one.

While the swap works out for many companies, especially if it fits into the fleet buying timeline and a company is ready to replace its diesel trucks, there are other fleets that might benefit from an easier, more short-term drop-in solution.

And that’s what Range Energy’s trailer provides, because it doesn’t require any sort of retrofitting of the diesel engine, it’s just a pick-up-and-go solution.

It works with what Range calls the “smart kingpin,” which is packed with sensors to tell the trailer how hard the tractor is pulling. It then adds its own torque proportional to the amount the tractor is asking for, making loads feel lighter.

We got a chance to see a demo of it in action at ACT Expo last year, and let me say, it was one of the coolest demos I’ve experienced.

Since then, Range has had its trailer validated through independent testing, which said it can improve efficiency by 36% in average use cases. Given that fuel costs are a large part of any trucking company’s outlays, and that diesel fuel burned in heavy duty vehicles creates an outsized portion of smog-forming pollutants, this is a quick way to get some real improvements.

The trailer can also be used on electric trucks as an impromptu “range extender,” essentially just adding a larger battery carried by the trailer, in addition to whatever amount of energy storage the tractor has onboard.

There are some other companies with a similar solution, including a company called Trailer Dynamics in Germany. But the US and European markets are different, so there’s room for both in this realm.

Petaluma Egg Farm improves mpg by “50-70%” with electrified trailers

The news today is that Range Energy’s trailer has been put into service in a real-world test, including taking advantage of its large battery for refrigeration. Refrigerated or “reefer” trucks are used widely throughout the industry, but this is the first order Range has gotten for its electrified reefer solution.

The company in question is Petaluma Egg Farm, a family-owned business that serves Northern California grocery stores. It ordered and will deploy 10 of Range’s trailers over the next 12-18 months.

The order follows a successful pilot by the farm which it ran in July, testing the trailer on routes between 100 and 440 miles, and also on city distribution routes consisting of more than 15 delivery stops.

During the trial, the trailer had 100% uptime, and did not need any additional time for charging beyond typical downtime. Range says it delivered “up to 70%” mpg improvements. We followed up on that (since it sure seems like “up to” is doing a lot of heavy lifting there), and were told that “average” improvements tallied between 50-70% – but this is highly dependent on a number of factors, so take it with a grain of salt, especially given that the third-party test above showed 36% improvements on a standardized route.

Nevertheless, it shows that in this real-world circumstance, the trailer has worked well to reduce fuel costs for the company in question. And on routes that are perhaps easier-than-average, improvements better than 36% are possibly.

Electrek’s Take

We’ve been quite interested in Range Energy ever since demoing their system at ACT Expo and talking to their leadership.

While the system isn’t fully electric – the Range trailer is electric, but is still driven by a diesel tractor – it’s still a great way to drop in to a fleet and get an improvement right away.

We’d rather have everyone go all electric, which they will in the longer term. But in the short and medium term, this will still reduce pollution quickly.

The one thing we’re worried about is what Range will do once every truck already is electric. There’s still some use for these trailers in those circumstances, as they might fit into an ecosystem where tractors can be sold with a relatively smaller amount of energy storage for shorter routes that don’t need much energy, and then Range trailers can be added to those tractors for longer routes.

But this does feel like a more niche application. However, Range’s leadership seems to have good heads on their shoulders, and they’re a quickly moving company, so we think they’ll be able to figure something out.

Regardless, in the short term, this is quite a boon and we’d love to see more of these out there in the wild. Good on Petaluma Egg Farm for taking the initiative here.

Tesla announces 2025 holiday update with a few cool features

Tesla has officially announced its 2025 Holiday Update, and this year, the automaker is not using the usually bigger update for any groundbreaking stuff, but there are a few interesting new smaller features.

You will find the release notes in this article.

It’s that time of year again. Every December, Tesla bundles a bunch of features it has been working on into a “Holiday Update” to give owners something to play with over the break.

While previous years have focused on adding major apps like Apple Podcasts or Steam integration, the holiday updates have become gradually weaker over the last few years, and they now concentrate mainly on playful features with smaller tweaks and add-ons.

Tesla announced the rollout in a post on X today:

Here is a breakdown of the main features in the 2025 Holiday Update. They are in order that Tesla announced them, which is generally from most to least important new feature.

Grok with Navigation Commands (Beta)

Many automakers are intergrating LLMs into their vehicles and unsuprisingly, Tesla went with Grok, which is developed by xAI, a company owned by Tesla CEO Elon Musk.

Tesla started the integration with an update last summer, but it only consisted of running the chat bot on Tesla’s in-car computer. It was the equivalent of using Grok on your phone as it couldn’t interact with the car.

Now, the automaker is starting to give Grok access to some vehicle functions, starting with navigation. Tesla announced:

Grok can now add & edit navigation destinations, becoming your personal guide.

Tesla says that to use Grok for navigation command, you have to set Grok’s personality to ‘Assistant’.

Tesla Photobooth

The second feature Tesla announced in the holiday update is the “photobooth”:

Turn your car into a photobooth! Take selfies from inside your Tesla & give yourself a makeover with fun filters, stickers, and emojis. Share with others right from the Tesla app

It sounds like a Temu Snapchat. To activate it: Go to Toybox > Photobooth

Dog Mode Live Activity

Now, to a more useful feature, Tesla has updated Dog Mode with a live activity feed:

When Dog Mode is active, you’ll see a Live Activity on your iPhone featuring periodic snapshots of your vehicle’s cabin along with live updates on temperature, battery & climate conditions

Dashcam Viewer Update

Tesla also added a bunch of information to the Dashcam viewer:

Dashcam clips now include additional details such as speed, steering wheel angle & self-driving state

Santa Mode

You can update the car visualization to this image. Tesla writes in the notes:

Santa Mode now adds festive snowmen, trees, a lock chime & snow effects for a 3D visual treat

You have select ‘Santa’ in the Toybox to activate it.

Light Show Update

Tesla has a dded a new light to the song “Jingle Rush”:

Play instantly or schedule it up to 10 minutes in advance, either on a single vehicle or synced with friends. You can also control interior lighting, add display color effects & create longer custom shows

Custom Wraps and License Plates

Back to slightly more useful features, Tesla has added custom wraps visualizations:

Personalize your Tesla avatar with window tints, custom wraps & license plates. Use one of many preloaded designs or create and upload your own using a USB flash drive to make your vehicle unique

You can select ‘Paint Shot’ in the Toybox to access it.

Navigation Improvements

A slight change to the nav UI:

Reorder your navigation favorites & set Home or Work by dropping a pin anywhere on the map

You can also view suggested destinations based on your recent trips and habits while parked

Supercharger Site Map

In line with the navigation update, you get a cool 3D view at some Supercharger stations straight in the navigation:

You can now see a 3D view of select Tesla Superchargers by tapping “View Site Map”. When navigating to a pilot location, the site layout and live occupancy (Available / Occupied / Down) will be displayed upon arrival

This could be useful to plan exactly where you’ll park and could open the door to a reservation system, which could be specifically useful for pull-in stalls.

Automatic HOV Lanes Routing

Navigation now includes an option to use high-occupancy vehicle (HOV) carpool lanes. Your route will automatically select the carpool lane when eligible, based on time, location, passenger count & road restrictions

Controls > Navigation > Use HOV Lanes

Phone Left Behind Chime

Your vehicle will chime a few seconds after the doors close if a phone key is inside the cabin or a phone is left on the wireless charger and no occupants are detected. Phone key detection requires UWB-supported devices.

Controls > Locks > Phone Left Behind Chime

Charge Limit per Location

You can now save a charge limit for your current location while parked & it will be applied automatically next time you charge there

Controls > Charging

SpaceX ISS Docking Simulator

Become an astronaut and prove your skills by docking with the International Space Station. Control & guide the rocket in this 3D docking simulator game using a set of controls based on actual interfaces used by NASA astronauts.

Arcade > SpaceX ISS Docking Simulator

Other improvements

  • Enable or disable wireless phone charging pads in Controls > Charging (S3XY) or Controls > Outlets & Mods (Cybertruck)
  • Add Spotify tracks to your queue right from the search screen & scroll through large Spotify playlists, albums, podcasts, audiobooks & your library seamlessly, without paging
  • Take the vibes up another level with rainbow colors during Rave Cave. Accent lights color will change along with the beats of your music. App Launcher > Toybox > Light Sync
  • Lock Sound now includes Light Cycle from Tron Mode. Toybox > Boombox > Lock Sound

Feature availability subject to vehicle hardware & region

Electrek’s Take

This is a bit of a mixed bag, which is typical for Tesla’s Holiday Updates.

On one hand, many useless features that will be probably be used once or twice and never again, like the photobooth.

But on the other hand, you have some decent new features, specifically to the navigation system, which put together make for a more than decent upgrade.

Kia is still offering over ,000 off its entire EV lineup

Kia is extending one of its biggest promotions yet, knocking over $10,000 off every EV in its lineup.

Kia knocks $10,000 off EV models

Who said electric vehicles would get more expensive after the $7,500 federal tax credit ended? Kia must not have gotten the memo.

Last month, Kia launched a new promotion, offering a $10,000 customer cash discount for all EVs, including the EV6, EV9, and Niro EV. The discount knocks nearly 25% off MSRP on Kia’s cheapest model, the Niro EV. On the entry-level EV6, it’s 23% off MSRP, while $10,000 off the EV9 is about an 18% discount.

The discounts ended on December 1, but Kia has extended them for at least another month. During its Season of New Tradition sales event, Kia is now offering even more savings.

New Holland C314 mini track loader gets the full electric treatment

New Holland C314 mini track loader gets the full electric treatment

New Holland’s already excellent C314 mini track loader is even better for 2026 thanks to the debut of a new, all electric version that offers quiet, low maintenance, and emission-free running for round-the-clock operation.

State and federal governments may still be hashing out emissions laws and ZEV requirements, but it’s the municipal governments that write quiet our laws and noise ordinances, and it’s those laws that construction crews are struggling to work around as they bid for lucrative urban jobs. New Holland understands those construction customers’ needs, and its new C314X Electric mini track loader (announced at last month’s Agritechnica) is designed specifically for them.

“We launched the C314 two years ago, and it has become known for its excellent features,” says Francesca Asteggiano, Europe Construction Brands. “Today, we’re developing an electric version to meet growing demand for quieter, more compact machines — reinforcing our commitment to sustainability and innovation.”

C314X Electric


New Holland’s C314X Electric is designed and built in-house as the zero-emission evolution of the diesel-powered C314, and is powered by a 23.5 kWh li-ion battery that sends power to three electric motors — two drive motors and a single hydraulic motor for the boom.

The company says the new C314X has a rated operating capacity that matches the diesel unit at 460 kg (~1014 lbs.) and a hinge pin height of 2.2 m (~7.2 ft.).

Though still “just a prototype” at this point, CASE and New Holland products have a history of making it to production. If when it does, company reps say it will be available in two undercarriage configurations, a “narrow track” version 890 mm wide that can fit through garden gates and man doors, and wide track version 1026 mm wide for heavier duty outdoor and agricultural work.

The stand-on machine uses controls that will be familiar to any mini loader operator — especially those with experience behind the controls of the diesel C314 — and all the implements and attachments that work on the diesel version bolt up to the C314X Electric, making it ideal (the company says) for livestock and horticultural farmers, landscape contractors and residential construction operations, thanks to multiple compatible attachments to ensure full versatility to dig, load, drill, and more.

Stay tuned for pricing and availability, likely set to be announced during ConExpo 2026.
