BYD and Mogox debut factory-built Level 4 autonomous bus in Singapore

BYD and Mogox have unveiled the B90, an 8.5-metre Level 4 autonomous bus, at Singapore Urban Mobility Week 2026. The electric model made its global debut in right-hand drive. It pairs BYD's bus platform with Mogox's Mogo AutoPilot software, and it's aimed squarely at international markets.

The division of labour is clean. BYD handles vehicle engineering and manufacturing. Mogox — the trading name of Beijing-based Zhidao Network Technology — supplies software, system integration and operating know-how. The partners fit autonomy hardware and software during production, not after. That's intended to improve compatibility and allow deployment at scale.

The sensing stack runs on cameras and solid-state LiDAR (laser-based ranging), localised for left-hand traffic. The system handles mixed traffic, junctions and bus stop approaches. A low floor and very short rear overhang help on narrow streets and ease boarding for elderly passengers and people with reduced mobility.

How does Mogox speed up new markets?

Mogox splits market adaptation into seven reusable modules, from regulations and vehicle platforms through fleet management to local support networks. The idea: shorten each new rollout. Singapore serves as the launchpad. The company holds the contract for the city-state's first official Level 4 bus project and has passed the Land Transport Authority's first milestone test.

Its partner network is already multinational:

• ComfortDelGro Bus in Singapore
• LG Electronics in South Korea
• Sales-Lentz Group and Clément Bayard in Luxembourg

Mogox's own Mogobus vehicles run in over 20 Chinese cities. For BYD, the tie-up delivers a factory-built autonomous option for export markets — something the world's largest e-bus maker previously lacked.

What does this change for European rivals?

Potentially plenty. BYD now bundles the bus and the autonomy in one factory-integrated package, pairing Chinese hardware with Chinese driving software. That could undercut European players such as MAN, which relies on an outside partner for its own autonomous bus programs.

The right-hand-drive layout opens familiar doors. It offers a route into markets like the UK, where BYD already supplies thousands of electric buses, letting autonomy follow an established customer base rather than start from zero.

Will transit agencies trust it?

That's the friction point. Norway's Ruter found in 2025 that Chinese-built buses could potentially be stopped remotely by their manufacturer. Adding driverless control to that picture is likely to sharpen scrutiny of Chinese software in public transport procurement across Europe.

What to watch next: the B90's first export contract, further Land Transport Authority milestone tests in Singapore, and whether any European or UK operator signs on despite the remote-control concerns Ruter raised.
