China EV Tech: Huawei ADS Wins, Toyota Strikes

China’s EV market delivered two revealing storylines on March 21: Huawei’s ADS 4.1-powered cars dominated a real-world urban assisted-driving competition in Jinhua, while GAC Toyota confirmed the bZ7 will launch on March 29 with an unusually China-specific tech stack that combines Huawei, Momenta and even Xiaomi ecosystem integration. Add Xiaomi founder Lei Jun’s public clarification on SU7 crash-test wording, and the day underscored a defining theme in the Chinese EV industry: software credibility, safety communication and ecosystem partnerships now matter almost as much as range and price.

Huawei ADS 4.1 posts a standout win in Jinhua

At the Jinhua preliminary round of D1EV’s intelligent driving competition, two camps went head-to-head under a “closed-book” format, meaning routes were not disclosed in advance. That matters because it better tests how city NOA systems handle unknown roads rather than rehearsed demo routes.

The event used a mature preliminary + final structure and covered complex mixed urban environments including:

• U-turns at signalized intersections
• Community roads with mixed vehicle and non-motor traffic
• Rural road encounters and blind corners
• Station drop-off zones with temporary parking
• Multi-point routing under live traffic-light conditions

The morning session featured the Momenta camp:

• IM LS6 n- Buick Electra L7 / Buick Zhijing L7
• Yangwang U7
• Denza Z9GT

The afternoon session featured the Huawei camp, all running the latest Huawei ADS Max V4.1.0:

• Voyah Dreamer
• Aito M8
• Avatr 11
• Luxeed S7
• Stelato S9

The headline result was clear: Luxeed S7 advanced with a record-setting score of 117.89 points and zero takeovers, setting the best result in the competition’s history to date.

What made the Jinhua test meaningful

Unlike controlled proving-ground demonstrations, the Jinhua route was designed to stress core urban assisted-driving capabilities over 17-18 km, with 19 traffic lights, 5 waypoints, and 6 test points. Expected completion time was around one hour, though the best performers were significantly quicker.

This is important because Chinese consumers are increasingly evaluating smart driving systems on three practical metrics:

1. Coverage: Can the system handle more city scenarios?
2. Safety: Does it avoid risky behavior and minimize interventions?
3. Efficiency: Can it complete routes smoothly without hesitating or getting lost?

That framework was visible in the scoring.

Momenta camp: Buick breaks through

The Momenta group delivered a competitive morning session, but with more penalties and takeovers than the Huawei cars later in the day. Still, Buick Zhijing L7 recovered from an earlier setback in Wenzhou and secured advancement to the final.

Key Momenta results

A few takeaways stand out:

• Buick Zhijing L7 won despite not being the smoothest on raw intervention count, suggesting its overall balance across safety, route completion and efficiency was strong enough to top the group.
• IM LS6 had the fewest takeovers at just one, showing that low intervention count alone does not guarantee the highest total score.
• Yangwang U7 and Denza Z9GT were hurt more by efficiency and route-execution issues than by pure scenario coverage.

D1EV noted all four Momenta-based cars avoided deductions in NOA scene coverage, which suggests the underlying capability envelope is broad. The differentiator was execution quality in edge cases.

Huawei camp: smoother, faster, more mature

The afternoon was where the performance gap became difficult to ignore. According to the event report, the Huawei group looked more fluid, more efficient and more composed in the same broad categories of road environment.

Key Huawei results

The standout details are especially noteworthy:

• Luxeed S7 finished the course in 44 minutes
• Zero takeovers earned it an additional bonus
• Its final 117.89 score was reported as the best in the event’s history
• Voyah Dreamer also completed the route with zero takeovers
• All five Huawei vehicles reportedly avoided deductions in all-scenario capability

In other words, Huawei ADS 4.1 did not just complete difficult urban tasks; it did so with a level of consistency that translated into the competition’s highest recorded scores.

Why Huawei’s result matters beyond one competition

It would be wrong to treat one event as a definitive industry ranking. Vehicle calibration, software versioning, route specifics and scoring methodology all influence outcomes. But this result still matters because it aligns with a broader market perception: Huawei has become one of the strongest names in China’s urban assisted-driving race.

Several details support that conclusion:

• All five Huawei-camp vehicles used the same latest-generation ADS Max 4.1.0
• The route included narrow community roads, mixed traffic and temporary obstructions
• The best cars showed not just safety, but strong decision-making efficiency
• D1EV explicitly highlighted progress on small roads and construction-like segments

For consumers, that translates into a more usable city NOA experience. For rivals such as Momenta, XPeng, NIO and Li Auto, it raises the pressure to improve stack maturity in messy real-world scenarios rather than only headline feature lists.

GAC Toyota bZ7 shows how joint ventures are changing in China

If the Jinhua event showed where software leadership is heading, GAC Toyota’s bZ7 showed how legacy global brands are adapting to survive in China’s EV market.

The flagship electric sedan will officially launch on March 29, with five variants already in pre-sale at RMB 156,800 to RMB 209,800. On pricing alone, that places it directly into one of the most competitive parts of the Chinese pure-EV sedan market.

But the real story is not just the price. It is the supplier map.

According to D1EV/Kuai Technology, the bZ7 combines:

• Huawei DriveONE electric drive
• Huawei HarmonyOS cockpit
• Momenta R6 end-to-end assisted driving model
• Xiaomi ecosystem integration

That is remarkable for a Toyota-badged sedan.

Why the bZ7 could be a turning point for Toyota in China

Toyota has often been criticized for moving too cautiously in China’s battery EV segment. The bZ7 suggests a far more pragmatic strategy: instead of insisting on a fully Toyota-defined software stack, it is embracing the Chinese EV supply chain where it is strongest.

That includes several consumer-friendly selling points:

• Large 5130 mm body and 3020 mm wheelbase for executive-sedan space
• Optional dual-chamber air suspension on Max trim
• Premium comfort features such as:
  • seat ventilation, heating and massage
  • HUD
  • facial recognition
  • Yamaha audio
  • rear wireless phone charging
• A roof-mounted lidar, underscoring serious assisted-driving ambitions

Most striking is its positioning as a car that bridges competing Chinese tech ecosystems. D1EV described it as effectively the first model to combine Huawei and Xiaomi ecosystems in one vehicle. In a market where users often build digital habits around one ecosystem, that interoperability could be a meaningful differentiator.

Comparison: Jinhua smart-driving winners vs Toyota’s new entrant

The competition result and the bZ7 launch are separate stories, but they intersect around one issue: who can deliver convincing real-world assisted driving at scale.

For Toyota, the message is straightforward: it is entering a market where Chinese buyers increasingly expect a smart-driving system that has already proven itself in live traffic, not just in product slides.

Xiaomi SU7 safety discussion shows the importance of technical credibility

The third development of the day was smaller in commercial scale but important in brand communication. Xiaomi founder Lei Jun publicly clarified remarks made during the new SU7 presentation regarding crash-test physics.

He referenced a China Automotive Technology and Research Center test involving:

• 50% offset frontal collision
• 60 km/h vehicle-to-vehicle crash speed for each car
• 120 km/h relative speed
• 1.44x the collision energy of the standard test condition

Lei acknowledged that, during the launch event, he misspoke when describing the test as equivalent to “driving into a wall at 120 km/h.” Critics correctly pointed out that in physical terms, two equal-mass cars colliding head-on at 60 km/h each is not equivalent to one car hitting a rigid wall at 120 km/h; the latter would be far more severe.

Why does this matter? Because as Chinese EV brands become more sophisticated, engineering communication matters almost as much as engineering itself. Consumers are no longer only wowed by big screens and acceleration figures. They scrutinize safety claims, test procedures and technical wording in real time.

For Xiaomi, the quick clarification was the right move. It helps preserve credibility at a moment when safety performance is becoming a major selling point across the EV industry.

Why This Matters

These three developments reveal where China’s EV market is heading in 2025:

1. Assisted driving is becoming the main battleground

Range and charging remain important, but urban NOA performance is increasingly central to product differentiation. The Jinhua results suggest that software execution quality can now meaningfully shape brand perception.

2. The supplier ecosystem is reshaping the market

The bZ7 demonstrates that even a global giant like Toyota may need to rely on Chinese software, cockpit and ecosystem partners to stay competitive locally.

3. Technical literacy among buyers is rising fast

Lei Jun’s clarification shows that EV consumers in China are highly engaged and quick to challenge vague or inaccurate safety claims. That raises the bar for every automaker.

4. Joint ventures are being forced to localize more deeply

For years, many joint-venture EVs struggled because they felt like global products adapted for China. The bZ7 appears to invert that formula: it looks more like a China-developed EV wearing a Toyota badge.

Global Implications

For overseas observers, the bigger takeaway is that China’s EV race is no longer just about low-cost manufacturing or battery scale. It is increasingly about:

• integrated software stacks
• live urban assisted-driving performance
• cross-brand technology partnerships
• ecosystem-led user retention

That has implications well beyond China. If Chinese suppliers such as Huawei and Momenta continue to prove their systems in demanding real-world environments, they could become more influential in global vehicle platforms, whether directly or through joint-venture channels.

Toyota’s bZ7 is especially instructive here. A multinational automaker adopting a deeply localized Chinese tech architecture shows how power in the automotive value chain is shifting from traditional OEM engineering centers toward regional software champions.

What to watch next

The immediate next step is the final round of the Jinhua smart-driving competition, where Buick Zhijing L7 and Luxeed S7 were set to face a wider field including models from NIO, Zeekr, Li Auto, XPeng, Xiaomi and others. That should give a broader benchmark across leading Chinese smart-driving systems.

At the same time, the March 29 launch of the GAC Toyota bZ7 will be an important test of whether a joint-venture brand can turn China-first technology integration into real consumer momentum.

The broader trend is unmistakable: in China’s EV market, the winners will be the brands that can combine solid hardware, mature assisted driving, credible safety messaging and seamless digital ecosystems. On March 21, Huawei looked strongest on software execution, Toyota looked more willing to adapt, and Xiaomi was reminded that in the EV era, every technical claim is instantly audited by the market.
