During a “Uni Wheel Tech Day” event held in Seoul earlier today, Hyundai Motor and Kia Corporation presented a potentially game-changing approach to the design of an EV’s drivetrain. The Universal Wheel Drive system, or “Uni Wheel” for short, moves main components to the wheel hub, creating additional space in a given vehicle’s interior. Learn more in the video below.
While the global mobility market slowly but surely transitions into the bright, all-electric future, many of the design techniques and necessary mechanical components have changed and in many cases, been minimized. One key component in ICE vehicles however, has remained relatively the same in the leap to EVs – the drivetrain.
Power created in internal combustion engine vehicles is transmitted from the engine through the transmission, then out toward the wheels via drive shafts and constant velocity (CV) joints. In EVs, the engine and transmission are replaced by a motor and reduction gear, but the method of power transmission to the wheels is still the same.
Electric motors are more compact and when combined with flat EV platforms, have created a lot more interior space within the same vehicle footprint compared to ICE cars. However, those motor(s) still take up space in the front and/or rear of an EV.
Today, Hyundai and Kia have introduced a new drive system solution that can create even more platform space, while maintaining the efficiency necessary for effective EV range. We’ll explain it as best we can, but Hyundai Motor’s images and video below are an excellent guide as well. Meet Hyundai and Kia’s new Uni Wheel system.
Hyundai’s Uni Wheel system frees up more interior space
Kia and Hyundai shared details of the new Uni Wheel technology in a press release following its Tech Day event held in South Korea earlier today. Described by its makers as a “paradigm-shifting vehicle drive system,” the Uni Wheel uniques moves the main drive system components to the vacant space within an EVs wheel hubs.
We’ve seen other passenger EV developers like Lordstown Motors try in-hub motors and fail (and go bankrupt), but have also seen startups specializing in commercial EV technologies like REE Automotive develop a similar approach with its proprietary REEcorners.
Hyundai has taken a similar yet unique approach with the Uni Wheel system that utilizes a special planetary gear configuration consisting of a sun gear in the center, four pinion gears on each side, and a ring gear surrounding everything (see second image above).
Traditional ICE vehicles utilize CV joints, but by moving them closer to the wheels requires a short drive train length and as a result, a decrease in efficiency and durability – especially over bumpy terrain. Hyundai and Kia’s Uni Wheel system on the other hand, can transmit power with almost zero changes to efficiency, regardless of wheel movement. Per Kia:
Power generated by the motor is transmitted to the sun gear, which in turn engages the pinion gears to rotate the ring gear. This is connected to the wheel to drive the vehicle. Uni Wheel’s pinion gears are connected to each other to form two linkages, and this multi-link mechanism enables Uni Wheel’s multi-axis movement to allow a wide range of suspension articulation.
The result is more platform space and in return, more room within an EV’s interior, including cargo space plus roomier trunks and frunks. The technology also opens the door to a wider design opportunity for non-conventional seating configurations within the cabin, which could prove fruitful as we continue to develop and integrate more autonomous driving technologies into our vehicles.
Still following? I truthfully didn’t quite grasp exactly how the Uni Wheel technology works until I watched the full video posted by Hyundai Motor Group you can view below. Sometimes it’s best to leave it to the experts, especially when visuals are involved.
Looking ahead, Hyundai and Kia say they plan to continue to perfect the Uni Wheel system so that future customers can experience mobility in a “completely different and new way.” When we may see this system integrated into an actual EV remains uncertain at this point, but Kia and Hyundai Motor state they have already applied for and registered eight patents related to the technology in South Korea, the US, and Europe.

After Donald Trump’s US election win, French energy giant TotalEnergies has hit the pause button on Attentive Energy, its planned offshore wind farm off the New York coast.
“Offshore wind, I have decided to put the [Attentive Energy] project on pause” with Trump’s return, said Total CEO Patrick Pouyanne on Tuesday at an energy conference in London. “I said to my team, the project in New York, we’ll see that in four years. But the advantage is it’s only for four years.”
Total’s offshore wind project is Attentive Energy, which is an 84,332-acre area around 54 miles from its nearest point to New York and 42 miles from its nearest point to New Jersey. Attentive Energy has the potential to generate 3,000 MW of clean energy to power nearly 1 million homes.
The company won the rights to develop Attentive Energy in a record-setting auction in 2022 and planned to bring it online in the early 2030s. But the project is currently in a very early phase, and it’s not permitted. It hasn’t filed a construction and operations plan with the US Department of the Interior, and that review process can take at least three years, which would be particularly challenging, if not impossible, under an administration that openly opposes the offshore wind industry.
Trump is a vocal critic of offshore wind and has repeatedly vowed on the campaign trail to target the industry with an executive order on his first day in office. His plans are vague but probably relate to lease sales and permitting. He’s also chosen pro-fossil fuel fracking executive Chris Wright as secretary of energy.
However, Trump won’t be able to cancel offshore wind farms that are fully permitted and are at more advanced construction stages.
Total is retaining Attentive Energy’s lease so it can resume work on the offshore wind project after Trump’s term ends under a more environmentally friendly administration.

With US President-Elect Trump reportedly planning to cut federal incentives, EV sales are expected to surge in November and December. Right now, major discounts are slashing upwards of $10,000 to $20,000 off some of the most popular EV models, but that could change in 2025.
EV sales are expected to surge with discounts on the line
According to Cox Automotive, “EV sales are expected to surge in November and December” ahead of Trump taking office.
“We may see an increase in electric vehicle (EV) and plug-in hybrid (PHEV) sales over the next few months as buyers move to take advantage of discounts that may disappear in 2025,” Charlie Chesbrough, senior economist at Cox Automotive, said.
A Reuters report earlier this month claimed Trump’s transition team was planning to kill off the $7,500 federal tax credit for clean car buyers.
Chesbrough explained that with fewer discounts on the line, buyers are expected to take advantage of them while they are still being offered, leading to “robust activity through the end of the year.”
In October, EV sales in the US reached a milestone. With another 106,155 units sold last month, over 1 million EVs have now been handed over to buyers.
EV lease deals are adding up
Higher incentives and discounts have helped fuel the growth. In Q3, EV incentives were over 12% of the vehicle’s average transaction price, much higher than the industry average of about 7%.
The $7,500 federal tax credit is the biggest factor behind the discounts. Although the credit is for EV purchases, a loophole enables automakers to pass it on through leasing.
Combined with other offers like loyalty and conquest, lease discounts, and bonus cash, some EV discounts are reaching upwards of $10,000 to even $20,000.
For example, you can score up to $21,150 off the 2024 Acura ZDX luxury SUV with combined discount offers. Ford is also offering up to $17,500 off its F-150 Lightning pickup through an end-of-year promo. A few EVs are even available to lease for under $300 this month.

EVs for lease under $300 per month in November 2024
With the $7,500 credit, the 2025 Chevrolet Equinox EV can be bought for as little as $26,100. GM calls the new electric SUV “America’s most affordable 315+ mile range EV.”
Honda just extended its ultra-low $229 per month lease offer to 17 additional US states after introducing it in California last month. For a nearly $50,000 electric SUV, $229 per month (36 months, 10,000 miles per year) is a pretty good deal.

Several owners in cold weather regions were experiencing difficulties entering their vehicles because the door handles wouldn’t open, the windows, which need to go down about an inch to open the doors, would jam, and even the charge port would freeze shut.
While charge port heaters have been in vehicles for years, Tesla never really gave the option to owners to specifically defrost their charge ports. Instead, it would activate when turning on the overall or rear defrosting functions of the vehicles.
This is now changing.
Not A Tesla App, which tracks Tesla software updates, is nothing that some Tesla vehicles are now getting the specific option to activate the charge port heater with the latest software update:
Tesla has finally added a solution to this problem. You can now manually turn on the charge port heater by going to Controls > Service > Charge Port Heater. However, the feature is not available on all vehicles. It’s only appearing in the release notes for a very small segment of vehicles. We’ve confirmed that it is showing up on a 2024 Model X and some 2023 Model Ys on Tesla software update 2024.44.3.1.
The change is coming right in time for the cold weather, and it should enable owners to target the charge port when needed – increasing efficiency.
Electrek’s Take
To be honest, I haven’t heard many issues about frozen charge ports since the first winter with the Model 3. I had this issue myself during the first winter.
There were a few reports about it the next two winters, but Tesla did help a lot simply with a software update to better manage the airflow toward the charge port area. Then, when the heater was introduced, it seemed to have basically eliminated the issue.
I still like to have a direct option to activate the specific charge port heater. It makes sense.
