The race to electrify heavy-duty freight transport in Europe is heating up. While international attention has heavily focused on futuristic designs like the Tesla Semi, Chinese manufacturing giant BYD used the IAA Transportation 2026 trade fair in Hannover to showcase a heavy-duty contender that prioritizes raw performance and practical logistics: the BYD ETT 44.
Featuring a more traditional exterior aesthetic masking an advanced, purpose-built electric architecture, the new ETT 44 is engineered to challenge established European diesel giants and upcoming American imports alike.
Heavy-Duty Performance and Technical Specifications
Underneath its conventional commercial workhorse exterior, the ETT 44 4×2 utilizes BYD’s proprietary Ultra-safe Blade Battery technology. Powered by a massive 651 kWh lithium-iron-phosphate (LFP) battery pack sitting on an 851-volt architecture, the vehicle delivers an impressive 742 hp (743 PS), with a peak output scaling up to 1,000 hp (1,000 PS).
Gross Combination Weight: Up to 44 tonnes (four tonnes higher than competing models like the Tesla Semi).
Unladen Weight: 10,950 kg.
Claimed Range: Up to 599 km (approx. 600 km) on a full charge.
Axle Options: Available in 4×2 configurations, with a 6×2 model also rolling out to broaden fleet versatility.
One of the most persistent hurdles for long-haul electric trucking has been long charging windows. BYD addresses this directly by integrating high-power charging compatibility designed for commercial viability.
While conventional CCS2 chargers allow the truck to pull up to 420 kW (recharging from 20% to 80% in roughly an hour), hooking the vehicle up to a dedicated Megawatt Charging System (MCS) unlocks its true potential.
Recharge Time: Boosts state of charge (SOC) from 20% to 80% in under 20 minutes.
Range Replenished: A quick 20-to-80% top-up adds an extra 399 km (approx. 400 km) of operational range.
Industry-Leading Warranty and Ecosystem Integration
To ease fleet operators’ anxieties regarding long-term asset depreciation, BYD has introduced an exceptionally strong warranty package. The Blade Battery is backed by a 10-year or 1.2-million-kilometer warranty, comfortably eclipsing the standard six-to-eight-year coverage windows common across the European commercial sector.
Beyond long-haul transport, the underlying platform is designed for scalable versatility. BYD plans to roll out the technology across rigid trucks and terminal tractors tailored for logistics hub maneuvering.
Inside the high-roof cab, long-haul drivers are catered to with a sleeping berth, a large 12.8-inch infotainment display, and seamless integration for Apple CarPlay and Android Auto.
Market Outlook: A Crowded European Landscape
BYD is entering a dense marketplace. Europe’s heavy transport sector already features heavyweights from Mercedes-Benz, Volvo, MAN, and Scania, while independent logistics disruptors like Sweden’s Einride have already committed to massive pre-orders of rival vehicles.
However, by offering an integrated ecosystem comprising vehicle manufacturing, proprietary battery tech, and high-power charging infrastructure, the BYD ETT 44 arrives with the specifications and backing necessary to fundamentally disrupt Europe’s freight corridors.
BYD is no longer content to control the production of its electric vehicles, plug-in hybrids and batteries. The Chinese automotive giant is also investing heavily in the logistics required to deliver those vehicles to customers around the world. And if the latest reports from China are accurate, its maritime ambitions are about to become considerably larger.
According to reports published by maritime outlets including New Ships and Robin Assasfina, BYD has reportedly ordered ten additional car-carrying vessels to supplement its existing fleet of eight. If the plan proceeds as expected, the company could operate 18 Ro-Ro ships within the next three years, creating one of the most substantial manufacturer-owned vehicle transport fleets in the industry.
The timing is hardly accidental. BYD’s domestic market is becoming increasingly difficult, while its international business is expanding at a much faster rate. Owning the ships that carry its vehicles could give the company greater control over delivery schedules, reduce its reliance on external logistics providers and help it push further into Europe and other key markets.
Ten New Ships Could Add Capacity for 92,000 Vehicles
The reported new vessels are expected to have a capacity of approximately 9,200 vehicles each. In shipping terminology, that is measured in CEU, or Car Equivalent Units—a standard used to describe vehicle-carrying capacity.
Ten ships of that size would add approximately 92,000 CEU to BYD’s fleet. Combined with the eight existing vessels, which reportedly carry between 7,200 and 9,000 vehicles each, the manufacturer’s total single-voyage capacity could reach roughly 150,000 vehicles.
That figure alone is impressive, but the more important number is annual throughput.
BYD’s existing fleet is reported to support exports of around one million vehicles per year. With ten additional ships arriving between 2027 and 2029, the company could potentially increase its global transport capacity to more than 2.2 million vehicles annually, with some estimates placing the eventual figure closer to 2.5 million.
The precise annual capacity will depend on routes, turnaround times, port operations and other logistical factors. Nevertheless, the direction is clear: BYD is building the infrastructure required to export vehicles on a much larger scale.
BYD’s Eight Existing Ships
BYD’s maritime expansion began in January 2024, when the company started adding dedicated vehicle carriers to its fleet. The eight vessels currently associated with the manufacturer are:
Explorer No.1
Hefei
Changzhou
Shenzhen
Xi’an
Changsha
Zhengzhou
Jinan
These are Ro-Ro, or roll-on/roll-off, ships. Unlike conventional container shipping, Ro-Ro vessels allow cars to be driven directly onto the ship and secured across multiple decks. That makes them particularly suited to transporting large volumes of finished vehicles.
For BYD, the strategy is about more than simply owning ships. It is about controlling another critical part of the automotive supply chain.
Domestic Sales Are Falling, but Exports Are Rising
BYD’s shipping investment comes at a time of significant change in its business.
According to the figures supplied, the company’s domestic sales in China fell by 43 percent year over year, to approximately 1.15 million vehicles. At the same time, exports surged by 88 percent, reaching around 1.12 million vehicles.
Those figures put domestic sales and overseas deliveries surprisingly close together. They also highlight how important international markets have become to BYD’s growth strategy.
The reported export total represents approximately 35.4 percent of all Chinese vehicle exports, including both battery-electric and plug-in hybrid models. Deutsche Bank estimates cited in the supplied material suggest BYD could export between 1.9 million and 2.2 million vehicles in 2026, nearly double the previous year’s figure.
Other industry analysts reportedly believe BYD could exceed 2.5 million exports by 2027.
If those projections are accurate, the company’s shipping fleet is not merely a logistical convenience. It is a strategic necessity.
Why BYD Wants Its Own Ships
The global automotive industry has experienced significant logistics disruption in recent years. Vehicle manufacturers have faced shortages of transport capacity, higher shipping costs and delays caused by geopolitical tensions.
The supplied reports also point to maritime constraints linked to the conflict involving Iran, which have complicated international shipping routes.
By owning its own car carriers, BYD can potentially reduce exposure to those disruptions. It can plan vessel deployment around its production schedules, prioritize strategic markets and reduce dependence on third-party shipping companies.
There is also a commercial advantage. Exporting vehicles can offer higher profit margins than selling them in China, where intense competition and an ongoing price war continue to pressure manufacturers.
That makes the shipping fleet part of a broader strategy: produce the vehicles, build the batteries, develop the charging technology and increasingly control the process of getting the finished cars to customers.
Europe Is the Next Major Battleground
Europe remains one of BYD’s most important international targets. The company has expanded its model range across the continent, offering electric and plug-in hybrid vehicles in a growing number of markets.
However, importing vehicles from China comes with additional costs. The supplied text states that BYD-made vehicles imported into Europe currently face an additional 17 percent tariff, although the exact applicable rate can vary by model, production origin and trade classification.
That is why BYD’s planned European production is so significant.
The company is reportedly approaching mass production at its factory in Hungary, which would allow it to manufacture vehicles within the European market and avoid the additional tariff applied to China-made imports.
Local production could also shorten supply chains, improve delivery times and make BYD more competitive against established European, Japanese and Korean manufacturers.
BYD’s Expansion Goes Beyond Electric Cars
Although BYD is best known internationally for its electric vehicles, its business is considerably broader.
The company develops and manufactures its own batteries, including technologies used in its Blade Battery platform. It is also investing in ultra-fast charging infrastructure, an area that could become increasingly important as charging speeds improve and electric vehicle adoption expands.
The addition of a large vehicle-carrier fleet completes another part of that vertically integrated strategy.
BYD is attempting to control more of the journey from raw materials and battery production to vehicle assembly, charging technology and international delivery. Few automakers have pursued that level of integration with such speed.
A New Kind of Automotive Power
The reported order for ten additional Ro-Ro ships illustrates how dramatically BYD’s ambitions have changed.
The company is no longer operating solely as a Chinese automaker exporting vehicles when shipping capacity is available. It is building a dedicated global distribution network designed to support millions of vehicles per year.
If the reported expansion goes ahead, BYD could have 18 car-carrying ships in service by the end of the decade’s early years, with a transport capacity approaching 2.5 million vehicles annually.
That would give the company greater control over its international growth at precisely the moment when its domestic market is becoming more challenging.
For European automakers, the message is straightforward: BYD is not simply bringing more cars to the market. It is building the industrial and logistical infrastructure to keep doing so at a much larger scale.
BYD has put its electric-vehicle battery technology through an extraordinary real-world stress test, with the Yangwang U7 covering 30,000 kilometers in less than nine days while traveling at an average speed of around 240 km/h for most of the test.
The extreme endurance run was designed to push the electric sedan’s battery, thermal-management system, charging technology and drivetrain to their limits. Even more impressive, the test was conducted in hot and humid conditions rather than inside a controlled laboratory environment.
At the conclusion of the test, BYD reported that the Yangwang U7’s 150-kWh battery had suffered just 1.3 percent degradation.
That means the battery reportedly retained 98.7 percent of its original capacity after 30,000 kilometers of high-speed driving, 350 ultra-fast charging sessions and repeated exposure to substantial thermal loads.
BYD Yangwang U7 Drove for Nearly Nine Days Without Stopping
The endurance test took place at BYD‘s 400-hectare testing facility in Nanning, China. The site includes a high-speed circuit and dedicated Flash charging infrastructure designed to deliver extremely high charging power.
The Yangwang U7 remained in continuous operation for 8 days, 19 hours and 58 minutes.
For virtually the entire test, the electric sedan traveled at approximately 240 km/h. The objective was straightforward: put an enormous amount of stress on the battery by rapidly consuming energy, returning to the charger, replenishing the battery and repeating the process.
This cycle continued around the clock.
The result was a remarkable 30,000 kilometers of accumulated distance in less than nine days.
For comparison, that distance is equivalent to driving from London to Sydney and back several times, although the Yangwang U7 completed the equivalent distance on a test track at speeds that would be extreme even for a high-performance gasoline-powered car.
The Yangwang U7 Used More Than 1 MW of Charging Power
The charging portion of the test may be even more significant than the high-speed driving itself.
The Yangwang U7 is equipped with a 150-kWh battery, and during the endurance test it was repeatedly charged from approximately 40 percent to 80 percent.
According to Chinese media reports, charging power exceeded 1 megawatt, or 1,000 kW.
One charging session reportedly took around 10 minutes.
That is an extraordinary charging rate for a passenger vehicle and illustrates the direction in which China’s most advanced EV manufacturers are pushing charging technology.
Instead of attempting to fill the entire battery every time, BYD repeatedly restored a relatively small portion of the pack before sending the Yangwang U7 back onto the track.
The vehicle completed approximately 350 Flash charging sessions during the test.
350 Charges Does Not Mean 350 Full Battery Cycles
The headline figure of 350 charging sessions needs some context.
The Yangwang U7 was not repeatedly charged from zero to 100 percent. Each charging event replenished the battery from approximately 40 percent to 80 percent, meaning that each session represented roughly 40 percent of a complete battery cycle.
As a result, 350 charging events correspond to approximately 140 equivalent full charge cycles.
That distinction is important when evaluating battery degradation.
Even so, subjecting an electric-car battery to approximately 140 equivalent full cycles while simultaneously driving at around 240 km/h, operating in hot weather and repeatedly charging at more than 1 MW represents an unusually demanding test.
Battery Degradation Was Reportedly Just 1.3 Percent
After completing the 30,000-kilometer endurance run, BYD inspected the battery and reported degradation of only 1.3 percent.
In other words, the 150-kWh battery reportedly retained 98.7 percent of its original capacity.
Battery degradation is influenced by numerous factors, including temperature, charging speed, depth of discharge, charging frequency and driving conditions. High-power DC charging combined with sustained high-speed operation can generate significant heat, making thermal management particularly important.
The Yangwang U7 test therefore provides an interesting demonstration of how BYD’s battery and thermal-management systems perform when several demanding conditions occur simultaneously.
The result is especially notable because the battery was not subjected to a gentle laboratory test designed to maximize longevity.
It was repeatedly charged at an extraordinary rate after being heavily discharged during sustained high-speed driving.
The Test Was Conducted in Extreme Heat and Humidity
The environmental conditions made the test even more challenging.
Temperatures at the Nanning facility reached approximately 36 degrees Celsius, while relative humidity climbed as high as 80 percent.
Despite those conditions, the Yangwang U7’s air conditioning system operated continuously, maintaining an interior temperature of approximately 24 degrees Celsius.
That detail matters because the vehicle’s energy consumption was not limited to propulsion.
The battery was simultaneously supplying power for the electric motors, climate control and other vehicle systems while the car was traveling at very high speed.
According to calculations based on the reported figures, the Yangwang U7 consumed approximately 70 kWh/100 km during the endurance test.
That figure might appear extremely high compared with the official energy consumption figures of many electric cars, but the circumstances are anything but typical.
Driving an enormous electric sedan at approximately 240 km/h for days on end creates vastly greater aerodynamic drag than normal highway driving. Vehicle mass, tire resistance, drivetrain load and continuous air-conditioning use also contributed to the energy consumption.
Why Driving at 240 km/h Matters
Speed is one of the biggest factors affecting an electric vehicle’s energy consumption.
Aerodynamic drag increases dramatically as speed rises, meaning that maintaining 240 km/h requires exponentially more energy than cruising at normal highway speeds.
For that reason, the Yangwang U7 endurance test should not be interpreted as an indication of the car’s normal road-going range.
Instead, it is better understood as a stress test.
BYD deliberately created conditions that would rapidly drain the battery and generate substantial heat before immediately subjecting the pack to extremely high charging power.
That combination makes the test interesting from a battery-engineering perspective.
BYD’s Blade LFP Battery Takes the Heat
The Yangwang U7 uses BYD’s Blade battery technology based on lithium iron phosphate, or LFP, chemistry.
LFP batteries have become increasingly important in the electric-vehicle industry because of their combination of durability, thermal stability and resistance to degradation.
The chemistry generally offers lower energy density than some nickel-based battery technologies, but it can provide advantages in cost, longevity and thermal stability.
BYD has heavily invested in its Blade battery architecture, and the Yangwang U7 endurance test appears intended to demonstrate how the technology performs under unusually severe conditions.
The reported 1.3-percent degradation figure is therefore potentially significant.
However, one endurance test should not be treated as definitive proof of how every Blade battery will perform over the entire lifetime of an electric vehicle. Real-world degradation depends on many variables, including climate, charging behavior, driving style, battery temperature and vehicle use.
30,000 Kilometers in Nine Days Is More Than a Range Test
This was not a conventional electric-car range test.
The purpose was not to determine how far the Yangwang U7 could travel on a single charge. Instead, BYD subjected the vehicle to a repeated cycle of high-speed driving, rapid energy consumption and ultra-fast charging.
The test effectively compressed a huge amount of battery usage into less than nine days.
Covering 30,000 kilometers in 8 days, 19 hours and 58 minutes means the vehicle averaged roughly 142 km/h across the entire test period when charging stops are included.
Considering that the car spent a significant amount of time charging, its average speed while actually moving had to be substantially higher.
The test therefore represents an extreme workload for the battery and vehicle.
What the BYD Yangwang U7 Test Could Mean for EV Owners
For consumers, the most interesting part of the test may not be the 240-km/h driving or the 1-MW charging figure.
It is the reported battery durability.
One of the biggest questions surrounding electric vehicles is how quickly their batteries lose usable capacity over time. Faster charging has traditionally raised concerns about heat generation and accelerated degradation, particularly when combined with repeated high-power charging.
BYD’s results suggest that modern battery-management and thermal-management technology can potentially mitigate some of those concerns.
If the reported figures are independently validated and prove representative of production vehicles, they would strengthen the case for high-power charging without necessarily requiring a dramatic sacrifice in battery longevity.
That is increasingly important as automakers move toward charging systems capable of delivering hundreds of kilowatts and, in some cases, more than 1 MW.
BYD Is Pushing EV Charging Technology Into New Territory
The Yangwang U7 test also highlights the broader technological race taking place among Chinese EV manufacturers.
Charging speed has become one of the industry’s major battlegrounds. While early electric vehicles often required lengthy charging stops, newer architectures are increasingly capable of adding hundreds of kilometers of range in a matter of minutes.
BYD’s Flash charging technology is part of that push.
A charging system exceeding 1 MW requires far more than simply installing a larger charger. The vehicle’s battery cells, electrical architecture, cooling system, charging hardware and battery-management software all have to work together to safely handle the enormous power flow.
The Yangwang U7 endurance test was therefore as much a demonstration of the company’s charging ecosystem as it was a test of the battery itself.
