It was supposed to be a German powerhouse alliance. In 2022, Volkswagen and Bosch joined forces to create the Automated Driving Alliance (ADA) — a joint initiative aimed at developing scalable advanced driver-assistance systems (ADAS) covering SAE Level 2 and Level 3 autonomy. More than 1,000 specialists were brought on board. Over 1,500 test and data collection vehicles were deployed around the clock across Europe, the United States and Japan. The ambition was real, the investment substantial.
Four years later, VW is pulling the plug. According to reporting by Electrive, the partnership is coming to an end — and the breakdown is being framed internally not as a commercial dispute, but as a technological verdict.
The verdict: not competitive enough
VW's internal teams reportedly concluded that the ADA platform could not keep pace with rival systems, particularly in the Level 2++ category — a colloquial term for hands-free urban driving that goes beyond basic highway assist. The gap to competitors was deemed too wide, and the development pace too slow.
The context here matters. While the ADA partnership was still developing its platform, the competitive landscape shifted dramatically. Tesla's Full Self-Driving (Supervised) received regulatory approval in Europe. Mercedes-Benz launched its MB.Drive Assist Pro, and BMW introduced its Motorway & City Assistant across new model lines, including the recently released iX3. In China — now the fastest-moving ADAS market in the world — brands like BYD and Xpeng have deployed hands-free systems at mass-market price points, raising the bar globally.
VW Group CEO Oliver Blume is said to have raised concerns internally about the speed of ADA development. The result: a strategic review, and then a decision to exit.
€1.5 billion and four years
The financial dimension of this decision is significant. Volkswagen invested approximately €1.5 billion in the ADA project over the course of the partnership. That figure doesn't include the broader investment in Cariad, VW's embattled software subsidiary, which has already cost the group billions and undergone repeated restructuring.
Cariad issued a carefully worded statement acknowledging the review: "We regularly review our development partnerships and align them with strategic goals and market developments." The language is measured, but the implications are not — walking away from a flagship €1.5 billion programme after four years represents one of the most significant course corrections yet in VW's long-troubled software journey.
Bosch, for its part, had signalled confidence in the programme as recently as August 2025, when both companies announced continued development efforts. The speed of the about-turn suggests the internal evaluation at Cariad reached its conclusions quickly once the competitive benchmarking was completed.
Who comes next? Mobileye is the frontrunner
VW is not stepping back from automated driving — it is changing horses. According to sources cited by Electrive, the group intends to source new hardware and software for Level 2++ and above from a different partner, with Mobileye identified as the leading candidate.
This would represent a significant pivot. Mobileye — the Intel-spun-off Israeli company that dominates the global ADAS chip and software market — already supplies systems to dozens of automakers worldwide. Its SuperVision and Chauffeur platforms are among the most capable in series production today. For VW, partnering with Mobileye would mean abandoning the idea of proprietary in-house ADAS software in favour of a faster, proven route to competitive functionality.
That logic is increasingly common in the industry. General Motors has scaled back its Cruise ambitions. Ford shuttered its Argo AI programme years ago. The lesson from the past decade: building full-stack autonomous driving software from scratch, even with billions in investment, is extraordinarily hard to do faster than specialised suppliers and technology-native competitors.
What this means for Cariad — and VW's electric future
The ADA dissolution is the latest chapter in Cariad's turbulent history. The subsidiary, formed to give VW full control over its software destiny, has repeatedly missed development milestones and seen leadership turnover. The botched rollout of software for the ID.3 and ID.4 in their early years cost VW significant reputational ground versus Tesla.
Yet the stakes here go beyond embarrassment. ADAS capability is becoming a primary purchase driver, particularly in China where consumers now routinely compare hands-free driving systems across brands the same way they compare range or charging speed. In Europe, regulatory frameworks for Level 3 highway automation are now in force, and BMW and Mercedes are already deploying approved systems. VW needs a competitive answer, and it needs one in the near term — not in three more years of platform development.
The move toward Mobileye, if confirmed, would accelerate that timeline significantly. Mobileye's EyeQ system-on-chips power vehicles from BMW, Ford, Nissan, Volkswagen (previously, for lower ADAS tiers) and dozens of other manufacturers. Its higher-tier platforms — SuperVision and Chauffeur — are already in production with Zeekr and SAIC, with others queued behind them.
For VW's upcoming models, including the long-awaited affordable EV lineup based on the MEB+ and SSP platforms, having a credible hands-free driving system from launch will be critical. The departure from Bosch, painful as it is commercially, may ultimately prove to be the faster route to that goal.
Bosch faces its own reckoning
The end of the ADA is not trivial for Bosch either. The German supplier has staked significant resources on ADAS as a growth pillar in the transition away from combustion-engine components. Losing the VW partnership — one of the largest ADAS programmes in Europe — will require reassessment of its own roadmap and resource allocation.
Bosch has not issued detailed comment on the dissolution. Whether the more than 1,000 specialists who worked on the ADA platform will be redeployed within Bosch, or whether this triggers job cuts, remains to be seen.
What was the Volkswagen-Bosch Automated Driving Alliance (ADA)?
The ADA was a joint development partnership launched in 2022 between VW's software subsidiary Cariad and Bosch, aimed at creating a scalable platform for advanced driver-assistance systems covering SAE Level 2 and Level 3 automation. VW invested approximately €1.5 billion in the initiative, which employed over 1,000 specialists and ran more than 1,500 test vehicles globally.
Why is VW ending the Bosch partnership?
VW's internal teams concluded that the ADA technology was not competitive enough, particularly in Level 2++ hands-free driving systems. Rivals including Tesla, Mercedes-Benz, BMW, and several Chinese brands had deployed more advanced systems while the ADA platform was still in development, prompting the strategic reversal.
Who is likely to replace Bosch as VW's ADAS partner?
Mobileye, the Israeli chip and software company spun off from Intel, is reported to be the frontrunner to supply VW with new hardware and software for Level 2++ and above systems. Mobileye already supplies ADAS technology to dozens of global automakers and has more advanced production-ready systems than the ADA platform had reached.
