BYD Launches Autonomous Chip and Ultra-Long-Range Hybrid Amid Profit Crunch

BYD launches Xuanji A3 4nm chip for L3/L4 autonomy and Song Ultra DM-i hybrid with 310km EV range, as Q1 profit plunges 55.4% and sales decline for eight months.

BYD is pulling out all the technological stops – a homegrown autonomous-driving chip and a hybrid SUV with a claimed range of 1,845 kilometres – as it tries to reverse an eight-month slide in domestic sales and a sharp earnings contraction. The Shenzhen-based automaker unveiled the Xuanji A3 chip on May 28, billing it as China’s first 4-nanometre processor purpose-built for intelligent driving, while separately rolling out the Song Ultra DM-i plug-in hybrid that targets combustion-engine holdouts with an electric-only range of up to 310 kilometres.

The timing is anything but relaxed. BYD’s first-quarter net profit plunged 55.4% to 4.1 billion yuan, revenue fell 11.8% to 150.2 billion yuan, and the company has been wrestling with declining sales volumes for the past eight months. The market’s response to the chip announcement was measured: shares in Hong Kong climbed as much as 3% in early trading before paring those gains, a classic pattern for technology reveals that carry no immediate revenue impact.

Chip ambitions meet real-world pressure

The Xuanji A3 supports L3 and L4 autonomy functions and is already in mass production, BYD says. In a three-chip configuration the system can deliver more than 2,100 TOPS of computing power, while the company claims usage efficiency has doubled versus earlier generations. The strategy is clear: as China’s EV market pivots from raw price competition to software-defined features, controlling the semiconductor layer gives BYD a long-term differentiator. Rivals Nio, Xpeng and Li Auto are also developing their own chips, making this a race for vertical integration.

But analysts caution that hardware alone does not guarantee software leadership. BYD boasts more than 3.15 million vehicles on the road equipped with driver-assistance hardware, generating roughly 200 million kilometres of driving data each day. That fleet-scale data flow could accelerate development of autonomous functions, yet the company still needs to prove it can translate sheer volume into superior software – an area where competitors currently hold an edge.

Hybrid that stretches the tank

On the showroom floor, the Song Ultra DM-i offers a more immediate sales weapon. Prices start at 129,900 yuan (around $19,100) and top out at 159,900 yuan for the range-topping variant, with five trim levels in total. The powertrain pairs a 1.5-litre naturally aspirated engine producing 74 kW with a 175 kW electric motor. Buyers can choose a 26.6 kWh Blade battery that delivers 205 km of electric range, or a 38 kWh version stretching that to 310 km. Fully fuelled and charged, BYD quotes a combined range of 1,845 km and a fuel consumption of just 3.3 litres per 100 km when the battery is depleted.

Standard equipment includes the DiSus-C adaptive damping system and a tyre-burst stability control system, along with a 15.6-inch rotating central display and a 10.25-inch digital instrument cluster. The vehicle also comes with BYD’s “God’s Eye C” highway navigation assistant as standard, while higher trims can be optioned with “God’s Eye B”, which adds a LiDAR sensor for fully automated parking and urban navigation without driver input.

Two fronts, one bottom line

The Song Ultra DM-i follows several sedans launched earlier in the quarter with the same fifth-generation DM hybrid technology. BYD’s calculus is blunt: persuade combustion-engine owners to switch with compelling electric range for daily commutes while retaining the flexibility for long trips. Whether that pitch resonates in China’s brutally contested SUV segment will show up in sales numbers over the coming months.

The Xuanji A3, meanwhile, gives BYD a technology narrative it badly needs during a prolonged price war. Proprietary chips could eventually reduce system costs, improve functional integration and strengthen the company’s position in software-defined vehicles. But the proof will come in concrete metrics – higher order rates for models equipped with the new system, additional revenue from driver-assistance packages, and stabilising margins after a grim start to the year. The next quarterly report is the real verdict.
