China's lidar sensor makers Hesai, RoboSense stand to gain after fatal Xiaomi SU7 EV crash
China's leading lidar sensor makers Hesai Group and RoboSense Technology stand to benefit in the aftermath of a
fatal accident involving autonomous driving as safety-conscious consumers become more aware of their technologies, analysts said.

Autonomous-driving systems in high-end electric vehicles (EVs) tend to use lidar (light detection and ranging) sensors, which employ laser beams to measure distances to objects. The car that crashed in China's central Anhui province on Saturday, killing three people, a basic edition of Xiaomi's SU7, uses cameras, which are seen as more likely to be fooled by shadows, rain, fog and other factors.
'The accident will definitely boost adoption of lidars in cars, particularly EVs fitted with driver-assistant systems,' said Chen Jinzhu, CEO of Shanghai Mingliang Auto Service, a consultancy. 'Hesai and Robosense can expect a business increase in the next few years.'
The cause of the accident has not been revealed.
Xiaomi , a smartphone maker that launched the
hit SU7 , its first car, last year, said on Tuesday that it was assisting the police investigation.
The car was travelling at 116km/h with the driver-assistance system engaged, and the self-driving system alerted the driver to take over two seconds before the car hit a concrete barrier, Xiaomi said in a statement.

A driver-assistance system analyses real-time conditions around the car based on sensor data to navigate and make decisions such as whether to accelerate past a slower vehicle. The existing systems in mainland China all require a human driver to be at the car's controls and alert at all times.

China's BYD expands car-carrier fleet to bolster EV exports amid furious domestic competition
BYD , the world's largest electric vehicle (EV) maker, has taken delivery of two new car-carrying ships – the largest yet in a growing fleet – as it bets on export growth to counter brutal competition at home. The Shenzhen-based company took delivery of its sixth carrier, the BYD Changsha, which can transport 9,200 vehicles, on Tuesday, just three days after it received the Xi'an, another vessel with the same capacity. The company's six roll on/roll off vessels had a combined capacity of 45,600 vehicles, and another two ships with a combined capacity of 16,200 cars were due for delivery in coming months, BYD said. The Xi'an was put to work immediately; laden with 7,000 EVs, it set sail on Tuesday from Taicang, in eastern China's Jiangsu province, bound for European countries including Italy, the UK, Spain and Belgium, BYD said. 'The ships reflect BYD's resolve to achieve higher sales in markets outside mainland China, since it can enjoy a higher profit margin abroad,' said Chen Jinzhu, CEO of consultancy Shanghai Mingliang Auto Service. 'With car carriers owned and operated by the company, it can quicken its export pace and save ocean transport costs.' BYD exported 374,200 vehicles in the first five months of 2025, up 112 per cent from a year earlier. Exports accounted for 21.5 per cent of its total deliveries, compared with just 10 per cent in 2024. As its EVs are subject to a 27 per cent tariff in the European Union, BYD's most affordable model, the Dolphin Surf, starts at €22,990 (US$26,679) on the continent. In mainland China, the same model, known as the Seagull, starts at 69,800 yuan (US$9,726), or about 63 per cent less.

Slick advertising, sports sponsorships help boost Chinese brands' fortunes in Europe
Parisian Alexandre Martins still remembers Chinese electronics brand Xiaomi's old stores in the French capital, where his parents and sister used to shop. Advertisement 'They were at good locations, like Chatelet [a commercial area in central Paris] … I used to go scout for stuff and then buy them online,' Martins said. The Chinese tech brand opened its first boutique in France in 2018, but had shut all of its stores in the country by 2022, opting instead to maintain a presence online and with partnered retailers and operators. 'I don't think they were making a lot of money … back then its image was not that good; there was always this sense that 'Ah it's Xiaomi, it's a Chinese brand, the quality is not good',' Martins said on Monday. Xiaomi is now preparing for a comeback, announcing plans this month to open 500 new retail stores outside China this year, especially in 'developed markets'. It said it aims to open 10,000 stores overseas in the next five years. Advertisement The decision to close all its stores in France in 2022 'corresponded to an adjustment in Xiaomi's retail strategy, which aimed to respond to the purchasing behaviour of the French', the company said on Thursday.

Chinese EVs: Xiaomi accelerates launch of Tesla Model Y rival YU7, citing strong demand
Chinese smartphone and car maker Xiaomi has moved up the launch of its latest electric vehicle (EV) model amid strong consumer interest in the SUV, which is seen as a potential challenger to the dominance of Tesla 's Model Y. Sales of the YU7 , the Beijing-based company's second production model, would start at the end of this month instead of in July as previously planned, founder and CEO Lei Jun said in a post on Chinese social media platform Weibo on Monday.

Deliveries of the premium SUV were expected to begin in July. Xiaomi would not comment on pricing or delivery dates. On May 27, Xiaomi president Lu Weibing said that the number of inquiries about the YU7's presale greatly exceeded those for the company's first model, the SU7, ahead of its debut in March 2024. The SU7 sedan, which competes with Tesla's Model 3, was an immediate hit, securing more than 70,000 orders in the month after its official launch. On June 1, Lu said on his Weibo account that Xiaomi was revving up mass production of the YU7.
