Volkswagen has announced it will deepen its self-driving partnership with Horizon Robotics through their Chinese joint venture Carizon, setting as its first target the delivery of SAE Level 3 driver-assist systems in China from H2 2027 onwards. The deal gives Carizon access to Horizon’s AI foundation model and will enable the collaboration’s extension into Level 4 commercial robotaxi development.

Carizon’s existing advanced driver-assistance system—which comes in around Level 2—has already entered mass production and will roll out across seven new electrified models from Volkswagen’s three Chinese joint ventures starting in Q3 2026. Next year, it will be expanded across vehicles using the automaker’s newly developed China Electronic Architecture. In a statement regarding the announcement, Chief Executive Oliver Blume said “China has become one of Volkswagen Group’s key innovation and technology hubs, particularly in software, artificial intelligence and automated driving.”

Horizon’s AI foundation model will pair with Carizon’s own C7H chip, which remains under development, and its proprietary GAIA world-model data platform. It should be noted this is not the same GAIA generative world model first introduced by UK firm Wayve in 2023.

The model gives Volkswagen a real-time scenario simulation capability intended to shorten testing cycles and support continuous over-the-air updates. Carizon Chairman Peter Bosch called the expanded tie-up “a powerful example of how we combine advanced AI technologies with strong in-house software and systems engineering.”

Carizon itself, a joint venture between Volkswagen’s software unit Cariad and Horizon established in Beijing in December 2023, represents one of the largest technology investments a foreign automaker has made in China: Volkswagen has committed roughly €2.4bn in total, split between a direct stake in Horizon and funding for the venture, in which Cariad holds 60% against Horizon’s 40%. 

The ID Unyx is co-developed by Volkswagen and Xpeng

Concurrently, Cariad proper has been reorganised by Volkswagen to become a coordinator of externally-developed software, rather than a software developer in its own right. The switch came after years of development issues—sometimes attributed to internal fighting between brands within the group—which in turn led to substantial delays for multiple vehicle launches.

For Volkswagen, the arrangement is squarely about closing a software gap that has let domestic rivals such as BYD, Li Auto and Xpeng dominate smart cockpit and driving-assistance features. Indeed, more than 30% of new cars sold in China in the first half of the year already came equipped with advanced navigation-assisted driving, according to the Ministry of Industry and Information Technology. For Horizon, locking in one of China’s largest vehicle producers as an anchor customer secures high-volume silicon demand and validation against rivals including Nvidia and Qualcomm.

Of course, Volkswagen is far from alone among legacy automakers in seeking out smart driving partnerships, particularly with Chinese firms. Stellantis has partnered with self-driving firm Pony.ai to trial robotaxis in Europe, and Mercedes-Benz continues working closely with Momenta on both driver-assist and robotaxi deployment. Meanwhile, Volkswagen itself has tied up with electric vehicle maker Xpeng to co-develop the ID. Unyx 08.

The push into smart-driving technology comes as Volkswagen looks to redirect its surplus Chinese manufacturing capacity elsewhere rather than scale it back entirely. Instead of conceding to lower domestic sales, it has instead added export routes to Kazakhstan and Uzbekistan, and signalled plans to reach the Middle East, Central Asia and Southeast Asia. 

Still, there is an expectation that the “in China, for China” approach to software will have some meaningful impact on its local sales. Blume explicitly stated that the deepened Horizon partnership would “reinforce our competitiveness in China, and open up new opportunities in selected international markets.”

However, that framing only holds up if Volkswagen can convert a licensing arrangement into genuinely differentiated technology, rather than parity with the domestic rivals already selling it as standard. Volkswagen is simultaneously weighing up to 100,000 job cuts and multiple plant closures at home, which makes this deal less a hedge against China’s software gap and more an admission that the group’s real competitive future now emanates from Chinese partners rather than Wolfsburg.
