How do you make a long-haul diesel truck emit 50% less CO2 without changing a single thing about it? Sounds like a riddle, right? A new pilot solution embraced by BMW Group Logistik and supplied by partner firm Trailer Dynamics here in Germany, though, can do just that. I spoke with Mo Koellner from BMW and Michael Nimtsch from Trailer Dynamics about this tech on a call earlier in the week.

As to the answer to the above riddle: This is a semi-truck trailer that has a massive battery pack (up to 600 kWh) installed in its floor, and that battery powers an electrically driven axle underneath the trailer. The solution isn’t conceptually novel; e-trailers, or electrified trailers, have been on the market in various forms for a number of years now (though the technology is still in a relative stage of infancy). The basic principle is simple, too. By adding a battery-electric driven power source to a diesel tractor-trailer, you reduce the fuel consumption of the diesel portion of the system. In other words, you’ve created a plug-in hybrid-electric big rig. Pretty straightforward, yeah?

What makes Trailer Dynamics’ solution cool is just how “plug and play” it is. In fact, the company says that its electric trailers can work with any truck they are physically capable of hitching to. No trailer-to-truck connection is utilized; the e-trailer operates totally independently. Trailer Dynamics says this makes its product unique* in the space, as most other e-trailer solutions require active communication with the connected truck to enable the electric-assisted drive. BMW is currently testing TD’s solution on its BMW Group Logistik fleet. (*US-based Range Energy also claims to work with basically any truck, and their solution seems quite similar to Trailer Dynamics. We covered them back in May. The biggest distinction I’ve seen is that Trailer Dynamics offers far larger batteries and is designed for use with European tractor-trailer configurations. BMW’s fuel consumption figures also seem to indicate TD’s solution may be more efficient, but it’s hard to know how apples-to-apples these numbers are given the pack size differences.)

The way TD achieves this is down to a proprietary sensor pack that lives in the kingpin of the trailer. There, a computer control model takes input from the sensors (used to monitor various forces on the kingpin) and converts that data into a decision about when and how much power to apply to the electric motors in the axle. The logic of the system takes into account the sort of things you’d expect. For example, if the trailer knows the truck is currently stopped and is beginning a start — when large trucks tend to make use of their fuel most inefficiently — it will apply very substantial power to get the truck rolling. The result is a huge reduction in the amount of diesel used. Similarly, if the system detects the truck is going uphill, electric assist will be applied generously to minimize the effects of an otherwise high fuel consumption situation. According to TD’s website, factors like weather conditions, route topography, and traffic can also be considered, though it was less clear to me how these play in to when the trailer applies power. The system can also be configured to disable itself if the battery capacity reaches a predefined cutoff point (important, as fleet operators ideally want a minimum level of charge guaranteed at any moment).

The system itself is, by the standards of passenger electric vehicles, some very heavy-duty stuff. Battery packs of either 400 kWh or 600 kWh are employed (a 200 kWh unit is coming later), with the 600 kWh configuration being the most desirable among TD’s prospective customers. That’s because the economics of efficiency apparently pay off best for longer routes, where a larger battery is going to be necessary. The electric motor unit outputs up to 580 kW (777 hp), which is impressive, but it’s the insane 13,000 nm of torque that’s doing the heavy lifting (literally). Charging is also pretty damn quick, with the 800V architecture supporting 44 kW AC and up to 350 kW DC fast charging. The supersized figures here make sense when you consider the weights at play — BMW is testing TD’s trailers with a payload of 16 metric tonnes, or over 35,000 pounds. (Specifically, BMW has been using them to haul electric drive units for its passenger cars.)

As for the end efficiency, BMW is seeing fuel consumption lowered by nearly 50% on some of the long-haul routes it’s testing, meaning emissions on those routes are cut in half. Even on shorter routes, the figure is in excess of 45% fuel savings. Because BMW is using 100% carbon-neutral sources to recharge the trailer batteries, it estimates that each e-trailer could cut up to 120 tonnes of CO2 emissions from its fleet each year. For comparison, assuming a “typical” ICE car emits around 5 tonnes of CO2 annually, each trailer optimally utilized is like taking 60 cars off the road. All that is to say: It’s hard to overstate how much fuel a real big truck uses.

BMW has also been testing TD’s trailers with electric trucks, where the system effectively acts as a range extender. Depending on the specific truck, payload, and route, BMW says the range of an electric truck could be extended by a factor of 2-3x, opening up entirely new scenarios for the use of BEV tractor units. In one test, BMW used an unspecified Volvo e-truck in combination with a TD mega trailer to go over 600 km (373 miles) without recharging.

In a perfect world, diesel trucks would be replaced with electric ones wholesale. But in reality, the design principle of trucks as long-life assets means that ICE trucking will stick around a fair bit longer than combustion passenger cars. If we can reach a point where e-trailer systems like Trailer Dynamics’ are minimizing trucking fuel consumption at scale, though, we can still have a real net-positive impact on emissions while that transition occurs. And because this kind of system benefits both ICE and EV tractors (arguably, the latter even more so), this is a scenario where the hybrid step-transition makes much more sense. There’s nothing redundant being engineered here for the sake of ICE trucks; these trailers will retain their usefulness in the age of BEV trucking.

For BMW, the EV trucking side of the equation has an added bonus — the low-liner “mega trailer” configuration it uses for a large amount of its transport fleet greatly limits the range of available EV truck options. Using TD’s mega trailer solution as a range extender is thus an excellent way to work around that challenge. (Mega trailers are a high-capacity trailer class specifically developed for use in the EU, where they remain extremely popular. These space-maximized trailers require a particular class of truck chassis with a very low deck floor for towing, and that leaves very little room for a battery.)

As for the challenges of stuffing a massive battery in the bottom of an already super-heavy-laden trailer? They’re not nonexistent. According to BMW, TD’s solutions are best for shipping in “cubed out” configurations — that is, utilizing the maximum volume of a container, not its maximum weight. And sure, the battery cannibalizes some of the available space for cargo. But, over time and with the evolution and refinement of the system (weight reduction is one of TD’s immediate goals), greater and greater payloads will become feasible. Human behavior is another big factor to consider. Suppose a tractor operator is still driving like a leadfoot. In that case, it’s possible to mitigate a fair bit of the system’s fuel savings (BMW saw fuel consumption variability of up to 20% during testing based on driver). On the economics, BMW believes that e-trailers will significantly lower fleet operating costs, offsetting initially higher acquisition costs for the equipment.

Down the road, TD suggests it could also start using its tech to assist in the on-road safety of tractor-trailers, applying power or engine braking force for stability management (for example, if a truck is in danger of jackknifing). Right now, the company is just getting started, and currently has seven trailers in operation (an eighth was just delivered).

While cleaning up our passenger cars will have a real effect on global CO2 emissions, the impact of trucking transport is something we should all be considering, too. According to data from the IEA, road freight accounts for 30% of all global transportation emissions, making it the second-largest contributor behind passenger vehicles — and by a wide margin. (For comparison, all air and sea transit contribute just above 10% of global emissions each. Rail sits at a measly 1%.)

Hyundai's EV plant raided by ICE, 'hundreds' taken into custody [Live Updates]

Hyundai-EV-plant-raided-ICE

The massive new Hyundai EV plant outside of Savannah, Georgia, was raided by ICE last week. Federal agents took hundreds of people into custody at the site, including executives from LG Energy Solution, Hyundai’s battery partner and co-owner of the plant.

Update 09/10/2025: A charter plane was shown taking off from the Incheon International Airport in South Korea on Wednesday, headed for the US.

According to reports (via The Associated Press), the plane landed in Atlanta, but cannot depart the US just yet due to unknown reasons on the US side.

The detainees are currently being held at an immigration detention center in Georgia. They are expected to be released and transferred to the Hartsfield-Jackson Atlanta International Airport, where the charter plane is waiting to bring them home.

The battery plant site that was raided is one of over 20 that South Korean companies are currently building in the US.

As the largest workplace raid by the US Homeland Security, the event is quickly spreading backlash among South Koreans.

Charles Kuck, an immigration attorney from Atlanta who represents several of the detained citizens, told The Associated Press that no other company in the US makes the machines used at Hyundai’s plant. So, they had to come from overseas to install or repair equipment at the plant. He added that many were doing so under various visa programs legally.

Why was the Hyundai EV plant raided by ICE?

After celebrating the grand opening of its new Hyundai Motor Group Metaplant America (HMGMA) in Georgia earlier this year, the Korean automaker said it’s “building the future of mobility with America, in America.”

On September 4, a construction site for a new battery plant was raided by US immigration authorities. Up to 475 people were arrested as part of an investigation into undocumented individuals. It was the US Department of Homeland Security’s largest single-site enforcement operation to date.

The South Korean Foreign Ministry issued a statement on Friday, September 5 (via Yonhap News), claiming that the individuals were mistreated.

“The economic activities of our companies investing in the US and the rights and interests of our nationals must not be unfairly violated,” South Korean ministry spokesperson Lee Jae-woong said.

The ministry’s spokesperson added that “We conveyed our concern and regret through the US Embassy in Seoul today.” Korea sent officials to Washington and to the Hyundai plant to establish an on-site task force to deal with the matter.

Update 09/08/25: South Korea reached a “broad agreement” on September 7 to release the roughly 300 Korean citizens detained in the US.

A foreign ministry official confirmed on Monday (via Yonhap News) that “We have agreed on a plan to bring all our citizens back home safely via a chartered flight.” The official added that the citizens will head home voluntarily rather than facing deportation.

Backlash is erupting in Korea after video footage circulated on social media showing the detained workers shackled before being loaded onto buses and DEA agents armed with guns outside the facility.

South Korean Foreign Minister Cho Hyun is in talks with Washington to discuss ways to prevent similar incidents from happening again, including increasing the visa quota for South Korean workers.

Meanwhile, President Donald Trump still believes the US and South Korea have “a great relationship.” Trump told reporters after a visit to the US Open tennis final on September 8 that “we have a great relationship with South Korea, really good relationship.”

Trump later posted on Truth Social that the US will “make it quickly and legally possible” to bring foreign battery experts to the US, adding, “What we ask in return is that you hire and train American Workers.”

Hyundai’s site in Georgia spans nearly 3,000 acres total and includes an assembly facility, two battery plants, a weld shop, and several others for training, logistics, and more.

As the largest economic project in Georgia, the plant, including Hyundai’s suppliers, is expected to create nearly 40,000 jobs while drawing $12.6 billion into the state.

Hyundai currently builds the new 2025 IONIQ 5 and 2026 IONIQ 9, its first three-row electric SUV, at the Georgia facility.

The ICE raid came just days after US President Trump hosted South Korean President Lee Jae Myung at the White House. It’s part of the administration’s aggressive crackdown on immigration. Lee has committed to investing another $150 billion in the US, including a new EV battery plant, as it seeks to ease trade tensions.

Joby Aviation and Uber to add Blade flights to Uber App, paving way for electric air taxis

Uber air taxi

Less than two weeks after completing its acquisition of aerial mobility business Blade, eVTOL air taxi developer Joby Aviation has expanded an ongoing partnership with Uber, Inc. to bring those flights to the popular rideshare app.

Regarding eVTOL development news, Joby Aviation ($JOBY) is a regular on the Electrek homepage. Joby is one of dozens of aerial mobility developers seeking certification to begin commercial air taxi operations worldwide with passengers on board.

However, Joby only began eVTOL test flights in the US with a pilot on board two years ago, followed by test flights in Japan in front of long-standing partner Toyota last November, and most recently, piloted flights in the United Arab Emirates this past June.

On Sunday, November 12, 2023, Joby Aviation’s bespoke eVTOL took off from the Downtown Manhattan Heliport and performed an exhibition flight across New York City ahead of plans for full commercial air taxi operations led by Joby in 2025.

That has yet to happen, but it moved closer than ever to reality last month, when Joby successfully acquired Blade, an established network of terminals and existing customers in markets like New York and Southern Europe.

Blade will continue its aerial and heliport operations as a subsidiary of Joby. However, the eVTOL developer is immediately implementing those air taxi services into the Uber App through a global partnership with the rideshare behemoth.

Joby to expedite eVTOL air taxi rides with Blade and Uber

Per Joby Aviation, it is expanding its global partnership with Uber Technologies to integrate the recently acquired Blade passenger business into the Uber App as early as next year. Joby and Uber have been working together since 2019, and in 2021, the former even acquired Uber’s Elevate division, which was focused on developing on-demand urban air transportation and eVTOL air taxi systems.

The eVTOL developer explained that the growing partnership with Uber “lays the foundation” for introducing its zero-emissions air taxis in key markets. Joby founder CEO JoeBen Bevirt elaborated:

We’re excited to introduce Uber customers to the magic of seamless urban air travel. Integrating Blade into the Uber app is the natural next step in our global partnership with Uber and will lay the foundation for the introduction of our quiet, zero-emissions aircraft in the years ahead. Together with Uber’s global platform and Blade’s proven network, we’re setting the stage for a new era of air travel worldwide.

Joby’s new air travel business from Blade flew over 50,000 passengers in 2024, operating from heliports in Manhattan to JFK airport and Newark Airport, or the Hamptons. In Europe, Blade offers flights from Nice to Monaco and Cannes and operations in St. Tropez and the French Riviera.

Through the acquisition, Joby intends to utilize Blade’s existing infrastructure and experience to accelerate its own launch of electric air taxi services. Currently, those planned markets include Dubai, New York, Los Angeles, the United Kingdom, and Japan.

Following its latest deal, Joby’s pending air taxi flights will be accessible through the Uber app. Uber president and COO Andrew Macdonald also spoke:

Since Uber’s earliest days, we’ve believed in the power of advanced air mobility to deliver safe, quiet, and sustainable transportation to cities around the world. By harnessing the scale of the Uber platform and partnering with Joby, the industry leader in advanced air mobility, we’re excited to bring our customers the next generation of travel.

So next year, you may be able to open the Uber app, order a robotaxi to a Manhattan heliport, then take an eVTOL air taxi to the airport for your flight. That’s pretty cool.
