New maglev world record achieved by China

 China achieved new world record with its magnetic levitation train by exceeding 650 km/h 

China achieves a new world milestone with its magnetic levitation train and seven seconds is all it took. Prototype reaches speed of 650km/h in 07 seconds. During trials at the Donghu Laboratory High-Speed Magnetic Levitation Electromagnetic Propulsion Technology Innovation Centre in Hubei province in central China, 650km/h was achieved by a 1.1 tonne vehicle running on a 1km test track on 17 June 2025. On a June morning in Hubei Province, engineers at Donghu Laboratory slid a sleek one-ton test vehicle onto a magnetic guide way, counted down, and fired 30,000 newton's of electromagnetic force. By the time observers blinked, the car blazed through a speed gun at 650 km/h (404 mph) then braked to a crawl before smashing into the end wall of the 1-km tube. Chinese state media promptly declared a fresh rail speed record, edging past Japan’s storied 603 km/h run in 2015.

Li Weichao, director of the centre, says that the trial used advanced short-distance boost technology, with positioning accuracy achieved within a margin of 4mm. The trial vehicle showed that it could safely brake within 220m, using electromagnetic boost brakes combined with a precise speed measurement and positioning system. The prototype’s party trick lies in brute acceleration. Linear motors embedded along the guide way push and pull powerful magnets on the vehicle’s underbelly, replacing wheels with a friction-free cushion of repulsion. According to project chief Li Weichao, the sled hit top speed after just 600 meters and safely stopped within the remaining 400. Engineers liken the motion to a pinball: all juice up front, gravity-free glide in the middle, opposite current to arrest the surge.

Back in 2008, when Beijing still painted fresh lanes for its first Olympics, China’s high-speed rail network amounted to a 120-km shuttle between the capital and Tianjin. Seventeen years and 45,000 tracked km's later, the country hosts two-thirds of the world’s bullet-train mileage and sells the technology everywhere from Serbia to Indonesia. The new maglev experiment signals that Beijing has no interest in tapping the brakes. Until now, bragging rights belonged to Japan’s superconducting maglev, which clocked 603 km/h on a 42-km mountain track near Mount Fuji. China’s sprint beat that by 47 km/h, but it did so with a much smaller vehicle and without a human driver aboard. Still, speed is speed, and the gap restarts a friendly but fierce technological rivalry spanning three decades.

Researchers say their current magnets can handle 800 km/h, though they must lengthen the test track. A 30-km segment outside Wuhan is scheduled for 2027, at which point the team hopes to flirt with four-digit speeds, around 1,000 km/h, once power electronics, cooling and passenger safety hurdles fall. Levitation removes wheel drag, yet air resistance balloons exponentially past 500 km/h. Donghu’s test tube isn’t evacuated, but its ends seal quickly, letting fans lower air density slightly, just think 3,000 m elevation. Future 800 km/h versions may need partial vacuum tunnels or deep-underground routes, concepts similar to the US hyper loop proposals shelved in 2023. Every extra 100 km/h demands disproportionate capital. Tracks must stay arrow-straight, tunnels must be wide enough to bleed off pressure waves, and stations need aircraft-grade security buffers. China’s answer is scale: it already built the 164-km Danyang-Kunshan Viaduct, the world’s longest bridge, just to keep its Beijing–Shanghai high-speed line flat. If any nation can pour enough concrete to domesticate 1,000 km/h rail, critics admit it is probably China. Several commercial maglev lines are currently operating in China, including in Beijing, Shanghai and Changsha in Hunan province. Last year, construction started on the first phase of a 48.7km maglev line between Changsha and Liuyang in Hunan province, described as China’s first inter-city maglev line, which will have a top speed of 160km/h. A seven-second experiment does not guarantee 1,000-km/h commuter runs next decade, but it shifts the Overton window of rail speed.

Airlines still own long-haul routes above 1,500 km, but maglev’s sweet spot, city pairs 500-1,000 km apart, throws shade on jets. The existing 431 km/h Shanghai maglev covers its 30-km airport hop in 7 minutes, yet tickets cost only $8. If 650 km/h prototypes mature into 50-car passenger sets, they could link Shanghai and Wuhan (810 km) in 90 minutes at business-class pricing, all on grid electricity instead of jet fuel. American rail watchers view the sprint as both sobering and inspiring. While California’s high-speed project inches along at 350 km/h, China leapfrogs toward airliner speeds. Baltimore’s shelved maglev proposal might revive if Chinese suppliers promise turnkey systems. Europe, wary of fresh competition, is already lobbying for stricter international safety rules. For now, we can only sit and envy China’s new revolution in train systems and break previous records.

Huawei launches HiCar 6.0

New connectivity features introduced by Huawei with HiCar6.0             

     

HiCar6.0 is Huawei's vehicle connectivity solution, designed to link smartphones and other devices directly with car systems, offering enhanced navigation, communication and entertainment features. Newly introduced HiCar 6.0 smart car solution, which comes with new intelligence and connectivity features. It not only improves the link between vehicles and humans but also contributes to boosting vehicle supply chains in the industry. Speaking of the features, the Huawei HiCar 6.0 solution brings an all-new multi-integration feature which helps to connect multiple devices. It supports First-Sight Aesthetics, which focuses more on visual innovation and users’ emotional resonance. Huawei HiCar connectivity offers a different main technologies which includes following:-

One-click navigation: like a smartphone toolbar, the interface is simpler and faster to use than with previous navigation systems.

Home control:- users can remotely control their home from the car’s screen, syncing several smart devices in one application.

Instant connectivity:- when entering the car, a smartphone connects automatically without requiring activation.

Video calls:- manage video calls using the vehicle’s screen, microphone and speakers along with a smartphone’s 5G network connection.

Gesture recognition:- specific hand gestures can be used to adjust volume, change songs or manage phone calls.

Application sharing:- share a smartphone’s feature-rich Android application ecosystem with the vehicle’s infotainment system, creating seamless user experience and connectivity inside and outside the car.

Fatigue monitoring:- using artificial intelligence, abnormal driver behaviour can be detected with the help of an instrument panel-mounted camera and a heart rate sensor on a watch or wrist band.

It further has a Shake to Transfer feature that simplifies the operation process. Just shake your phone to quickly project related information to the car computer and achieve efficient collaboration in seconds. The solution brings a multi-window layout which easily identifies various driving scenarios like navigation and helps in controlling the vehicle accordingly. The navigation info not only shows up on the central control screen but also syncs with the instrument panel to increase the driver’s focus. The cross-device split-screen feature is another benefit that allows car apps to run on phones. It lets you operate both the phone and the car systems together. Huawei has really made useful changes, and the HiCar 6.0 will debut for consumers with the upcoming electric vehicles in the near future. 

BMW Group has announced plans to integrate Huawei's HiCar system into its locally produced models in China starting in 2026. The move is part of BMW's strategy to enhance smart connectivity in its vehicles. The collaboration will see BMW team up with Huawei to develop smart applications for its vehicles based on Huawei's Harmony operating system. This integration aims to improve the user experience for drivers using Huawei devices in China. BMW stated that the partnership aligns with its broader strategy to promote deeper cooperation with Chinese partners and integrate them into its global innovation system. The German automaker is working with suppliers to foster ‘cross-cycle’ collaboration, indicating a long-term commitment to advancing technology in partnership with local Chinese firms.

HiCar6.0 is Huawei's vehicle connectivity solution, designed to link smartphones and other devices directly with car systems, offering enhanced navigation, communication and entertainment features. By adopting this platform, manufacturers aims to meet the growing demand for seamless digital experiences in vehicles within the Chinese market.
