BYD Bets Big on Trust: Full Self-Driving Liability Cover and a 1,845-km Hybrid Hit the Market

BYD unveils world's first double liability guarantee for autonomous driving mishaps and a plug-in hybrid SUV with 1,845 km range, shifting from price wars to tech differentiation.

BYD is rewriting the rules of China’s cutthroat auto market. Rather than just slashing prices, the Shenzhen-based giant is putting its money where its technology is. In a single week, it has unveiled two distinct offensive lines: a sweeping financial guarantee for autonomous driving mishaps and a plug-in hybrid SUV that jams nearly two full days of driving into a single tank and charge.

The company will assume full liability for accidents caused by its “God’s Eye” A and B urban navigation and intelligent parking systems from 28 May 2026. BYD calls it the world’s first double guarantee of its kind. New buyers are covered from the moment they take delivery; existing customers get the same protection after an over-the-air update to God’s Eye 5.0. The coverage runs for one year and applies only when the system is used correctly. If it fails, BYD foots the bill for repairs to the own vehicle, damage to third-party property and personal injury to others.

“Our long-term goal is zero traffic accidents,” chairman Wang Chuanfu told the Intelligent Strategy Event in Shenzhen. The ADAS package costs 12,000 yuan (around $1,770), a price point that ties the liability promise to BYD’s proven mass-market playbook.

The bet rests on an enormous data moat. At end of May, 3.15 million BYD vehicles equipped with driving-assistance systems were already on the road, generating up to 200 million kilometres of driving data each day. That real-world feedback lets BYD sharpen its algorithms faster than smaller rivals. “The company appears to be shifting its focus from price competition to technological differentiation,” an independent Shanghai analyst noted.

That technological push extends beyond software. BYD also unveiled the Xuanji A3, which it calls China’s first automotive-grade 4-nanometre chip for self-driving. A single chip delivers 700 TOPS; three combined hit 2,100 TOPS, enough to support Level 3 and Level 4 autonomous functions. The chip sits inside a new central computing platform that merges the cockpit, driver-assistance and electric-drive domains into a laptop-sized unit. Wang said more than 7,000 employees work in BYD’s chip research team alone.

Rivals Li Auto, Xpeng and Nio are all developing their own ADAS chips, but BYD is adding a commercial dimension they have yet to match. By absorbing financial risk, the company transforms a technical arms race into a question of trust.

On the product side, BYD launched the Song Ultra DM-i, a mid-size SUV that pushes the boundaries of plug-in hybrid range. Priced from 129,900 yuan to 159,900 yuan ($19,100–$23,500) across five trim levels, it pairs a 1.5-litre Atkinson-cycle engine (74 kW) with a 175 kW electric motor. Two battery choices are offered: a 26.6 kWh blade battery delivering 205 km of electric range, or a 38 kWh unit good for 310 km. Combined with a full tank, BYD claims a total range of 1,845 km. Fuel consumption when the battery is depleted drops to 3.3 litres per 100 km.

The Song Ultra DM-i comes standard with DiSus-C adaptive damping, a tyre-blowout stabilisation system, a 15.6-inch rotating display and a 10.25-inch digital instrument cluster. On the driver-assistance front, every version includes God’s Eye C for highway navigation; higher trims can upgrade to God’s Eye B with LiDAR, unlocking fully automated parking and urban navigation. The strategy is aimed directly at hold-outs still driving combustion-engine cars, offering them an electric commute without range anxiety.

BYD is also upgrading God’s Eye C to version 4.0, an end-to-end architecture that dispenses with high-definition maps, rolling out from September 2026. A separate Level 3/4 platform will feature a tenfold-redundant safety system covering sensors and brakes.

With these moves, BYD is leveraging its scale and vertical integration to offer something its competitors cannot easily copy: a comprehensive package of record-breaking efficiency, proprietary autonomy hardware and a willingness to stand behind it financially. In a market where margins are already squeezed, that might just be the decisive advantage.
