Race for Dominance: Chinese Automakers Compete to Conquer European Roads | Automotive Industry

With the aim of attracting British consumers, Tesla displayed its vehicles and vibrant signage at its dealership located at the iconic Hogarth Rotary in West London. Engaging with 500,000 drivers daily, the American automaker has established itself as the top seller of electric cars in the UK. However, passersby are now met with a new sight: the twin Chinese brands Omoda and Jaecoo, both under the umbrella of the state-owned Chery Automobile.

Chinese automotive brands are gaining traction across Europe, surpassing Korean competitors in sales for the first time in Western Europe as of September. The UK plays a crucial role in this success, with 30% of the 500,000 Chinese cars sold in Western Europe from January to September being purchased by British consumers, as reported by Berlin-based auto analyst Matthias Schmidt.

“Their success has been impressive,” remarks Steve Young, managing director of Hogarth dealerships, part of the Turkish group Setash Otmotiv. “This location makes a bold statement — it’s like waving a flag for us. Every minute the lights shift, and drivers find themselves captivated outside.”

Chinese automotive firms, bolstered by support from both national and local governments, are seizing the opportunity presented by the transition to electric vehicles to take a leading role in the global car market.

Challenges such as elevated trade barriers in the EU and U.S. and global supply chain disruptions are currently impacting the industry. Following the Netherlands’ move to regulate the Chinese-owned semiconductor firm Nexperia, export restrictions on critical semiconductors have begun to surface. Additionally, China’s limitations on rare earth metals crucial for various automotive components are unsettling for executives in the industry, leading Brussels to expedite negotiations for a moratorium similar to last month’s U.S.-China trade agreement.

Despite these hurdles, the UK continues to maintain an open stance and has emerged as a key playing field.

Leading the charge is China’s BYD, expected to surpass Tesla this year to become the largest battery electric vehicle manufacturer globally. Sales in the UK have soared tenfold in September compared to the previous year, establishing BYD as its largest market outside of China.

Other participants are also joining the fray, with Chery Automobile recognized as Britain’s top-selling Chinese manufacturer in October. The Jaecoo, Omoda, and Chery brands are targeting the UK market with electric and hybrid offerings that merge small batteries with traditional petrol engines. While MG represents a historic British name, its monthly sales, manufactured by state-owned SAIC, have surpassed those of the proud British nameplate Vauxhall (despite much of its production occurring in Germany).

Meanwhile, Swedish brands Volvo and Polestar, both owned by China’s Geely Automobile, alongside Great Wall Motors, Volkswagen-backed Expen, and Stellantis-backed Leap Motor, have each sold over 1,000 vehicles in the UK this year, preparatory to extensive product launches.

In the U.S., Chinese electric and hybrid vehicles are subject to a 100% tariff, while EU tariffs vary by manufacturer, falling between 17% to 38%. Although these rates are not excessive, they do not encompass hybrid cars, inadvertently encouraging Chinese manufacturers to market vehicles with higher emissions. Countries such as Italy and Spain are also emerging as targets for Chinese sellers.

Conversely, the UK—a significant car importer—is confronted with new tariffs but is keen on introducing electric models to fulfill carbon reduction goals.

Mike Hawes, chief executive of the Motor Vehicle Manufacturers’ Trade Association, stated that Britain desires both a thriving domestic market and a robust manufacturing base, grounded in “free and fair trade.”

“British car buyers benefit from having over 50 global brands at their disposal, and the market remains receptive to new entrants,” he asserts. Chinese brands are “stimulating competition as established market players adapt, enhance model development, and lower costs.”

While diplomatic issues may affect relations, recent tensions surrounding accusations of Chinese espionage have underscored the UK’s inconsistent attitude towards the world’s second-largest economy.

“The primary factor is [the lack of tariffs in the UK] — there are no domestic manufacturers to safeguard,” noted Tu Le, a former auto worker in Detroit and Shanghai who established the consultancy Sino Auto Insights.

According to Mr. Schmidt, British consumers are increasingly receptive to earlier waves of international brands. In the 1980s, Prime Minister Margaret Thatcher attracted Japanese manufacturers such as Nissan, Honda, and Toyota to establish operations in Britain, promoting the country as a portal to Europe (a distinction complicated decades later by Brexit-imposed rules of origin). The next wave consisted of imported Korean cars.

“We are witnessing history repeat itself,” Schmidt remarked. The UK has emerged as the initial European entry point for Chinese brands, despite the absence of a local manufacturing base.

Historically, low-quality Chinese cars were often dismissed as jokes by Western executives, a perception that has long subsided. Forecasts predict China will surpass Japan in 2023 to become the largest global exporter. Similar to Europe, Chinese brands are still selling in Russia, whereas their European counterparts have faced blockades following the full-scale invasion of Ukraine in 2022. Meanwhile, interest in Latin America is steadily increasing.

“There have been two waves of Chinese entry into Europe,” Young states. “Some of the initial products did not align with UK market demands. However, the brands have generally improved.”

The push for expansion, driven by regional competition in urban centers, has led to significant overcapacity within Chinese automotive factories. While the potential output could reach 55.5 million vehicles annually, actual production is just under half that figure, according to Bloomberg, citing data from the Shanghai-based Gasgoo Automotive Research Institute.

This has sparked fierce price competition within the Chinese market. The Chinese Communist Party has urged manufacturers to avoid excessive competitive behaviors, fearing “entrainment,” which could lead to destructive competition that stifles advancement.

Domestic pricing pressures contribute to more rational export strategies. Nevertheless, according to Andrew Bergbaum, global leader for automotive and industrial at consulting firm AlixPartners, the Chinese brands successfully breaking into European markets typically retail their vehicles at higher prices than in China—a sign of strength rather than desperation.

“The exporting brands are often well-established,” Bergbaum explained. “This represents a strategic move rather than a fire sale. The ability to command higher prices is highly attractive.”

China’s market influx coincides with Europe grappling with excess factory capacities. AlixPartners estimates that European automakers could be carrying two excess factories, potentially risking up to 2 million sales to Chinese brands in the forthcoming years.

This surplus capacity, combined with tariff incentives for local construction, suggests Chinese automakers might acquire properties from older rivals. This is already occurring in Barcelona, where Chery Automobile has taken over a factory previously owned by Japan’s Nissan.

European lawmakers and manufacturers argue that substantial subsidies have diluted the profits of Chinese automakers (though Western companies rarely lack support from their governments). Yet, the primary driver behind the surge in sales in China remains straightforward: consumer preference.

“British drivers are benefitting,” stated Tanya Sinclair, chief executive of British Electric Vehicle, a group funded by the industry advocating for increased battery sales.

“Regardless of the name change, the appeal is evident: high standards, competitive pricing, and innovation that enhances standards universally,” she affirms. “As long as the UK vehicle market is integral to the battery electric future, British cars will maintain a strong presence. However, competition and variety are paramount to a robust market.”

Exploring the features available in vehicles reveals their allure for customers. Special offerings from some Chinese brands range from novelty features like built-in karaoke apps to advanced technologies such as driver assistance systems—importantly, made available at far lower prices than European luxury brands.

“Ultimately, it’s about value,” Lee states. “These cars are exceptional. If I create a superior product that offers greater value to the customer, I’ve succeeded.”

Self-Driving Cars Hit UK Roads: The Challenging Journey Ahead

The timeless inquiry from the backseat remains relevant as we approach a new age of driverless vehicles. “Are we close?” For those in the UK, the promise of fully autonomous cars has been long-awaited, and the answer is “yes, almost”—but not quite there yet.

A pivotal advancement in the journey toward autonomous driving is on the cusp of realization. Waymo, known for its successful robotaxi operations in San Francisco and several other U.S. cities, announced recently that it plans to introduce its vehicles to London.

Specifics are limited, yet the potential is intriguing. The groundbreaking California-based firm stated that its self-driving service “will be providing driverless vehicles on this side of the Atlantic in 2026… We’re excited to cater to Londoners and the millions visiting London next year.”

These visitors may want to grab a London Underground Oyster card just in case. This past summer, the UK government announced initiatives aimed at enticing major tech companies, aiming to hasten the rollout of self-driving vehicles, with robotaxis potentially entering regulated public trials as early as spring 2026. However, regulations are still being finalized, which may mean that safety drivers remain in the mix for a while longer.

The British company Wave, in collaboration with Uber, has unveiled plans to develop a more modest Level 4 fully autonomous vehicle and to commence public road tests in London.

While Americans are leisurely experiencing self-driving vehicles, the UK’s winding road to this technology has been met with commitments that vanish like pedestrians in the rain. Back in 2018, Addison Lee, in conjunction with researchers from the University of Oxford, promised robotaxis by 2021.

A year ago, Nissan nearly achieved having one of its Leaf models drive itself without incident near Becton, east London. The then-transport secretary, Chris Grayling, forecasted self-driving cars arriving within four years, with small pods autonomously navigating around the O2 in Greenwich. The offspring of a British innovation, the Union Jack-patterned Sinclair C5 Tardis, was showcased in a Milton Keynes car park back in 2015. Vince Cable, the business secretary at the time, confidently stated that 100 of these would soon ferry passengers across town for just £2 each.

Meanwhile, in regions like the U.S. and parts of China, self-driving taxi services are nearing routine functionality, rendering Waymo’s impending arrival more significant compared to earlier aspirations and predictions.

In San Francisco, Waymo’s home base, self-driving cars have integrated seamlessly into daily life, traversing the city’s challenging hilly streets at a deliberate pace.

Since its full implementation in June 2024, it has established its place alongside electric scooters and city buses within the urban landscape. Riding a Waymo has become a must-try attraction for visitors, akin to experiencing the city’s historic trolley cars.

Democratic Mayor Daniel Lurie has advocated for expansion to rejuvenate the downtown district, but the streets still host many people experiencing homelessness, creating a stark contrast as high-tech AI-driven vehicles pass by individuals living in extreme poverty.

The modified white Jaguar iPace resembles surveillance equipment, featuring rapidly rotating cameras on each side and roof akin to a police siren. Advertised similarly to Uber or Lyft rides via an app, the absence of a human driver and the steering wheel twirling under its digital command serve as a poignant reminder of the economic upheaval these vehicles may precipitate.

Uber, which debuted in San Francisco in 2010, disrupted traditional taxi practices and created precarious gig jobs for drivers. Now, they are facing another wave of technological change.

In 2024, data referenced by The Economist indicated that the number of people employed by taxi firms in San Francisco increased by 7%, alongside a 14% rise in salaries. The newspaper noted that Lyft’s CEO David Risher predicted that self-driving taxis “will actually grow the market.”

Yet, those on the front lines may not share this optimism. An Uber driver from Venezuela expressed doubts when asked about Waymo while in San Francisco’s Mission District: “I think I have about a year left in this job.”

For passengers, riding a Waymo evokes a sense of entrusting their journey to artificial intelligence. Upon hailing the vehicle via the app, a warm welcome greets them, initially displaying their initials on the digital screen atop the car. Tapping the app unlocks the doors, while a friendly voice reminds riders to buckle their seatbelts. A broad selection of music is readily available, creating a truly intimate atmosphere behind the tinted rear windows.

Pressing the ‘Start Ride’ button on the touchscreen allows the car to smoothly merge into traffic. The gear shift, adorned with a message that reads “Keep your hands out of it,” spins like a ghostly fairground attraction.

Soon enough, riders cultivate a sense of comfort while remaining cautious enough to avert dangers. A scrolling map on the screen displays their route and updates the estimated time of arrival. The ‘Stop Now’ button will only engage once it’s safe to do so, but the option to change the original destination is appreciated.

Waymo has sparked diverse social reactions. Recently, three individuals stalled at a busy intersection in the Marina District, visibly disoriented with blinking lights, attracting cheers from onlookers, while one man executed multiple backflips off a nearby vehicle.

In July, a prankster gathered a crowd at a dead-end street, leading everyone to summon a Waymo simultaneously, creating a spectacle featuring 50 robocars. Earlier in 2024, one such vehicle was vandalized, covered in graffiti, and set ablaze during the Lunar New Year celebrations in Chinatown.

If the black taxi driver does not react directly, it’s possible a similar reception will greet the driverless taxis. Steve McNamara, executive director of the Licensed Taxi Drivers Association, remarked: “We observe kids hacking Lime bikes, but how long until surfing atop a Waymo becomes the latest TikTok sensation?”

McNamara maintains a calm demeanor: “This proposes a solution to a problem we don’t currently have. These vehicles may be performing excellently in San Francisco and Los Angeles, but London is unlike anywhere else. I’d like someone to elucidate how this self-driving car intends to navigate streets like Charing Cross Road at 11 p.m., where pedestrians are continually crossing.” [sensor] “When you’re on top of a Waymo, you know it will stop, so you just get out or disembark.”

Christian Wolmer, author of *Driverless Cars: On a Road to Nowhere*, echoes this skepticism, stating: “There are no pedestrian crossing rules in this environment. If Google expects adherence to pedestrian crossing norms for cars…”

Despite the experiences in the U.S., he staunchly doubts that fully autonomous taxis will hit the streets here next year, asserting: “Unless a human operator is present, the likelihood of that happening is zero.”

‘London is like nowhere else’: Can driverless cars adapt to transportation systems outside the US by 2026? Photo: Paolo Paradiso/Alamy

Waymo revealed its London plans partly to mitigate any surprise over test vehicles on the roads, initiating a lengthier mapping initiative. They feel emboldened after a self-driving trial spanning approximately 100 meters in San Francisco, which is a far from orderly or flat city, in addition to over a dozen other trials.

Carriers have long argued that regulation trumps technological hurdles. Even swift progress has limitations. The consultation’s outcome, which wrapped up last month, should pave the way for the pilot program, though confirmation is still pending.

While this may have spurred Waymo’s plans, transforming the testing program to operational vehicles still involves numerous challenges with the Department for Transport and Transport for London, indicating that broader legislation may take at least another two years to enact. Insurers have particularly raised concerns regarding liability in these scenarios.

Previous pre-legislative testing frameworks stalling other innovative transport modalities, such as electric scooters, are currently set to persist for eight years. Tony Travers, a professor at the London School of Economics, posits that self-driving cars may be more favorably received: “They will have to abide by regulations. Sure, they might contribute to congestion, but they’re not likely to induce chaos like electric scooters have.”

However, even with the arrival of driverless taxis, one might wonder, “So what?” suggests Walmer.

According to Waymo co-CEO Tekedra Mawakana, the answer lies in the fact that their vehicles are “reliable, safe, and magical,” with an emphasis on safety. Up to now, Waymo cars have been involved in a fewer number of accidents compared to human-driven vehicles over equivalent distances.

They also aim to provide a new form of autonomy to those previously lacking it. The Royal Institute for Blind People praised the Waymo announcement as the inception of “technology that allows for safe, spontaneous, autonomous movement.”

Waymo stated that its entrance into the UK market would entail investments in warehouses, infrastructure for charging, cleaning services, support teams, and would temporarily employ “human experts” in the driver’s position.

Transport Secretary Heidi Alexander has mentioned that the upcoming self-driving car revolution could generate 38,000 job opportunities within the UK.

However, it is professional drivers who face the greatest threat. Approximately 300,000 individuals hold private hire licenses, with an additional million expected to be in roles related to HGV and delivery services moving forward. Many of the UK’s 82,000 bus drivers have recently secured significant pay rises, while its 27,000 train operators are well-regarded for their labor efforts.

Consequently, surveys indicate that public sentiment in Britain is cautiously optimistic regarding self-driving vehicles, primarily stemming from fears surrounding job displacement due to artificial intelligence, even if human jobs haven’t been entirely eradicated yet.

Licensing and legal clarifications are still pending. McNamara expressed hope: “Who will grant approval? If I aimed to become a successful politician, I wouldn’t add my signature to that document.”

Solar cells that generate electricity could go the same way as razor blades.

Layering razor blades, rather than a single blade, gives people with hairy legs and hairy faces a more efficient way to get sunlight on those legs and faces. (which benefited them, as their skin was more clearly visible to the admiring audience). A big change occurred a few decades ago when two-blade, then three-blade razors were introduced and rapidly gained market share, not just hair. Single-edged razors are starting to seem a little outdated.

Plans are currently underway to create solar cells with multiple layers. In some schemes, each layer is made of a different semiconductor material that absorbs its own distinctive range of solar frequencies. Most modern solar cells are basically just one layer of silicon.

Already, some solar cell designers are using various perovskites (a type of mineral) instead of silicon.

Is the weight of electric cars causing strain on UK roads, bridges and car parks?

Cars have weight issues. The example of the Mini, designed to save fuel during rationing, highlights this trend. The size of cars is increasing, especially with the surge in popularity of SUVs.

Electric cars may look similar to traditional cars for now, but the key difference is the heavy battery they carry.

In our series debunking electric vehicle myths, we address common misconceptions about EVs, including range anxiety, carbon emissions, mining, and air pollution. In this final episode, we investigate whether electric cars will be too heavy for our roads and infrastructure.

Claim

As roads have evolved over time, concerns have arisen about whether electric cars will strain infrastructure like roads, bridges, and parking lots due to the weight of their batteries.

Matthew Lin, a columnist for the Daily Telegraph, recently questioned the readiness of charging infrastructure and the capacity of roads and bridges to handle heavier vehicles.

Conservative MP Greg Knight urged the UK government to test the structural integrity of multi-storey car parks and bridges against the added weight of electric vehicles.

The Asphalt Industry Alliance warned that small roads could suffer more potholes, while the Daily Mail suggested that multi-storey car parks might be at risk of collapse due to the weight of electric vehicles.

Science

Electric cars can be quite heavy. For example, General Motors’ Hummer weighs over four tons, with a significant portion of that weight attributed to its battery pack. On the other hand, the Tesla Model Y, a more affordable electric car, weighs 2 tons, still lighter than some traditional vehicles like the Range Rover or Ford F-150.

According to a transport and environment advocacy group, EVs are on average 300-400kg heavier than traditional vehicles. The weight of the battery increases by approximately 100kg for every 150km of range.

The increased weight of electric cars leads to more road wear and faster deterioration of roads. However, a study found that the wear is primarily caused by heavy vehicles like buses and trucks, rather than cars and motorcycles.

Regarding bridges, most in the UK can support vehicles weighing up to 7.5 tonnes, with a safety margin built into the design. There are no concerns about national highways, which are built to accommodate heavy goods vehicles.

Are there any precautions?

There are limitations to the weight of electric vehicles, especially in older car parks. While newer facilities can accommodate heavier vehicles, older structures may require reinforcement to handle the increased weight.

Options for multi-storey car park owners include strengthening the building or reducing the number of cars on each floor, which can impact profits.

Regular inspections are essential for car park owners to ensure the structural integrity of their buildings amid the transition to heavier electric vehicles.

Governments could encourage smaller cars through policies such as taxes and parking fees. Photo: Christopher Thomond/The Guardian

It’s worth noting that advancements in battery technology may address the weight concerns of electric vehicles in the future. Continued progress in battery energy density could lead to lighter EVs in the long run.

Encouraging smaller cars through policy measures like taxes and fees can have additional benefits beyond reducing road wear, such as resource conservation, carbon emission reductions, and improved parking lot management.

While EVs are heavier than traditional vehicles, it’s unlikely that their weight will significantly impact road infrastructure. Concerns about weight should not overshadow the importance of transitioning to zero-emission vehicles.

The process of using lasers to transform moon dust into roads

ESA’s PAVER project aimed to create paved surfaces on the lunar surface using melted lunar regolith. They conducted ground-based tests using a carbon dioxide laser and are planning to use a Fresnel lens on the Moon to focus sunlight. The successful use of lasers to melt simulated lunar dust is a significant development in addressing the challenges posed by lunar dust in future missions.

The construction of roads on the lunar surface is essential for astronauts who will likely be driving rather than walking during their missions. Lunar dust is fine, abrasive, and sticky, leading to equipment damage and spacesuit corrosion. For example, the Apollo 17 lunar rover overheated when its rear fender was lost and replaced with a lunar map, covered in kicked-up dust. The Soviet Lunokod 2 rover experienced a similar fate, dying from overheating after its radiator became covered in dust.

To prevent the accumulation of lunar dust, it is necessary to pave active areas on the Moon, including roads and landing pads. The idea of melting sand to create roads was originally proposed in 1933. ESA’s PAVER project, led by Germany’s BAM Institute for Materials Testing in collaboration with Aalen University, LIQUIFER Systems Group, and the University of Claustal in Austria and Germany, investigated the feasibility of building lunar roads using a similar approach. The project received support from the Institute for Space Materials Physics of the German Aerospace Center (DLR).

The PAVER consortium utilized a 12-kilowatt carbon dioxide laser to melt simulated lunar dust and create a glassy solid surface that can serve as a paved surface on the Moon. They achieved spot sizes of 5 to 10 cm in their trials. By utilizing a 4.5 cm diameter laser beam, they developed a strategy to produce a triangular hollow-centered geometry of about 20 cm in diameter. This approach allowed them to create solid surfaces over large areas of lunar soil suitable for roads or landing pads.

The project’s materials engineer, Advenit Makaya, explained that the current laser used in their experiment functions as a light source instead of lunar sunlight. To achieve equivalent melting on the lunar surface, the laser light would be focused using a Fresnel lens with a diameter of several meters.

The PAVER consortium’s methodology involved trial and error to determine the optimal laser beam size and geometry. They found that larger spot sizes were easier to work with, as heating on a millimeter scale produced challenging agglomeration due to surface tension. With their approach, they were able to create a stable layer of molten regolith, which could be better controlled. The resulting material is glassy and brittle but can withstand primarily downward compressive forces, potentially being repaired if needed.

The research team discovered that reheating a cooled track could cause cracks, leading them to minimize crossover in the geometry. The depth of a single melt layer achieved was approximately 1.8 cm. Depending on the required loads, the constructed structures and roads could consist of multiple layers.

The PAVER consortium estimated that a 100 square meter landing pad with a 2 cm thick high-density material could be constructed in 115 days using their approach.

The PAVER project originated from a call for ideas conducted by ESA’s Basic Activities Discovery Division through the Open Space Innovation Platform (OSIP). Out of 69 submissions, 23 ideas were implemented, including the PAVER project. The project has opened up promising avenues for future research in extraterrestrial manufacturing and construction.

Overall, the successful use of lasers to melt lunar dust represents a significant advancement towards the construction of roads and landing pads on the lunar surface, addressing the challenges posed by lunar dust in future lunar missions.
