Toyota bZ7: the biggest carmaker said yes, and bought the whole thing in
In America the cheapest Toyota EV costs $34,980 and will not let go of the wheel. In China, the bZ7 costs about €18,400, carries a roof lidar and twenty-seven sensors, and drives itself through city traffic. Toyota built none of it — not the software, not the motor, not the battery, not the cockpit.
This site already carries a review of the Toyota bZ. It is called “the biggest carmaker says no”, and the argument was that Toyota can build a car that drives itself and chooses not to sell one, because the moment it does, the liability moves from the driver to Toyota. The American bZ costs $34,980 to $46,750, runs Toyota Safety Sense 3.0, offers no hands-free mode at any price, and Toyota's answer to the question of when that changes is a “Level 2++” system promised for 2028.
That review needs its other half. On 29 March 2026, GAC Toyota launched the bZ7 in China: a 5,130 mm electric saloon from ¥147,800 with introductory incentives, about €18,400. It carries a roof lidar on the top variants, twenty-seven sensors in total, and Momenta's R6 system doing navigation-assisted driving on urban roads as well as motorways, plus full-scene parking, with no subscription. It took over 3,100 orders in the first hour and more than 10,000 in pre-sale.
So the biggest carmaker in the world does say yes. It says yes in the market where saying no costs it customers. And the interesting part is not that the answer changes at the border — this site has documented that pattern all year. It is what Toyota actually contributed to the car.
The introductory price, with limited-time incentives, of a Toyota that does urban navigation-assisted driving. About $21,400. The cheapest Toyota EV in the United States is $34,980 and does not.
The bill of materials is the story
Read the bZ7's supplier list as a document about who can build what in 2026.
- Drive unit: Huawei DriveONE, 207 kW / 278 hp, which Huawei rates at 97.5 per cent efficiency.
- Battery: CALB lithium iron phosphate, 71.35 or 88.13 kWh, 600 to 710 km CLTC, 3C charging for 300 km in ten minutes.
- Cockpit: Huawei HarmonyOS 5.0, with Huawei's MoLA large-language-model voice assistant and four-zone speaker recognition.
- Driver assistance: Momenta R6.
- Ecosystem: Xiaomi — the car appears in the Mi Home app, and Xiaomi magnetic Bluetooth buttons are promised.
Toyota supplied the body, the chassis engineering, the factory, the dealer network and the badge. Every system a buyer would name as the reason to choose this car over a Xiaomi SU7 came from somewhere else — and two of those somewhere-elses are Huawei and Xiaomi, who also sell cars.
This is not an accident of procurement. It is a structure. Toyota runs a dedicated Intelligent Electric Vehicle R&D Center in China under Yoshiki Konishi, and the bZ7 is the second car developed there end to end, after the bZ3X. The unit exists precisely so that Toyota-in-China can move at a speed Toyota-globally cannot, by buying what it would otherwise spend a decade building.
What Momenta R6 actually is
Momenta is the most consequential company in this review and most readers outside China will not have heard of it. It is a Chinese assisted-driving supplier, backed by General Motors, and it raised $752m in an IPO in July 2026.
Its architecture is a one-stage end-to-end model — perception, planning and decision-making in a single network rather than the modular pipeline most Western systems still use — trained in simulation built from large-scale fleet data. Momenta markets this as the “Flywheel Big Model”, the flywheel being the loop from deployed cars to data to a better model to more deployed cars. R6 is the reinforcement-learning generation of it.
On the bZ7 the lidar variant carries 1 lidar, 5 millimetre-wave radars, 11 high-definition cameras and 10 ultrasonic sensors. What it does: navigation-assisted driving on motorways, navigation-assisted driving in cities, and parking across scenarios. What it does not do is let go of the wheel — and that is not a Toyota decision. Since the April 2025 MIIT crackdown that followed the Xiaomi SU7 crash, hands-off Level 2 is not approved for Chinese consumers, the words “autonomous” and “automatic driving” are banned from marketing, and over-the-air updates to driving functions must follow the recall procedure. Every car in this class, from the Xiaomi YU7 down, is hands-on by law.
Toyota's answer to autonomy in the West is a system promised for 2028. Its answer in China shipped in March 2026, and someone else wrote it.
The cheaper one matters more
The bZ7 is the flagship, but the car that makes the argument is the one beneath it.
The bZ3X is a GAC Toyota electric SUV that starts around ¥109,800, roughly $15,000, with promotional pricing near $14,500. It runs Momenta 5.0, offers a roof lidar on two of its seven trims, and it has delivered more than 80,000 units in its first year. From September 2025 to April 2026 it was the best-selling joint-venture electric car in China for seven consecutive months, with a record 10,027 in April alone.
A Toyota with an optional roof lidar for fifteen thousand dollars is not a concept, a pilot or a regional experiment. It is the volume product. Meanwhile Toyota's American electric line-up opens at $34,900.
This is not simply “China gets more”
It would be easy, and wrong, to file this next to our export-gap findings as another case of the good version staying home. The bZ7's good version is not being withheld from Europe. Export to Europe is considered unlikely because the car itself is not exportable: built in Guangzhou, powered by Huawei, tuned for Chinese roads by a Chinese supplier, and priced against Chinese competition.
The cleaner comparison is BMW, because BMW ships in both markets and the difference is instructive. The European iX3 runs BMW's own stack, approved under UN R171, and will drive hands-off at 130 km/h in nine countries — motorways only. The Chinese iX3, built in Shenyang, runs a system co-developed with Momenta, validated against more than 100 million simulated kilometres and tuned for Beijing, Shanghai, Shenyang and Nanjing. It is far more capable in a city. It is also hands-on.
Two regulators, two different kinds of permission. Europe licenses a narrow competence and makes it legally hands-off. China licenses a broad competence and keeps a hand on the wheel. Neither market has the better car; they have differently shaped ones, and the shape is drawn by the regulator, not the engineer. We argued something close to this in the motorway paradox, and the two iX3s are the cleanest single illustration of it on sale.
Toyota's position is different again, and weaker. BMW has a stack of its own and chooses a local partner for a local market. Toyota, in its largest market, has no comparable system to choose between.
What this does to the 2028 promise
Our bZ review took Toyota's caution seriously, and it deserves to be taken seriously: a company selling 11.3 million vehicles a year has more to lose from a bad automated-driving launch than a startup has to gain from a good one. Liability is a real argument, not a cowardly one.
But caution and capability are different claims, and the bZ7 separates them. Toyota is not declining to ship urban navigation-assisted driving because it judges the technology unready — it is shipping exactly that, today, in the market where its competitors would otherwise eat it alive. What it is declining to do is ship it in a car it engineered, in a market where it would carry the reputational weight alone.
So the question for 2028 is no longer whether Toyota believes in the technology. It is whether the “Level 2++” system it promises for the West will be Toyota's own, or whether the company will do in Nagoya what it has already done in Guangzhou, and buy it.
What we cannot tell you
Four things, stated plainly, because this review is built from a launch and not from a year of data.
- The price is introductory. ¥147,800 is with limited-time incentives; the range runs to ¥199,800. Chinese launch pricing moves, usually downwards.
- Orders are not deliveries. 3,100 in an hour is a marketing figure from GAC Toyota's sales vice-president, Peng Baolin. The bZ3X's 80,000 deliveries are the number that has actually been tested by time.
- The lidar is a variant, not the standard fit — unlike the Xiaomi YU7, which fits its sensor set to every trim.
- Momenta publishes no independent safety record. There is no equivalent of an NHTSA filing, no third-party conformity assessment of the kind Gatik commissioned, and the disengagement data that would let anyone compare R6 with a Western system does not exist in public.
Fact sheet — Toyota bZ7 (China, 2026)
The ai.cars verdict
- Toyota sells, in China, a five-metre saloon with a roof lidar and urban navigation-assisted driving from about €18,400. Its cheapest American EV is $34,980 and offers no hands-free driving at any price.
- Toyota built the body, the chassis and the factory. Huawei supplied the motor and the cockpit, CALB the battery, Momenta the autonomy, Xiaomi the ecosystem. Two of those suppliers sell cars of their own.
- Momenta R6 is a one-stage end-to-end model — urban and highway NOA plus parking, no subscription — and it is hands-on because MIIT's April 2025 rules require it, not because Toyota chose caution.
- The bZ3X beneath it matters more: roughly $15,000, optional roof lidar, 80,000+ delivered in a year, and the best-selling joint-venture EV in China for seven months straight.
- This is not the export gap. The car is not exportable — it is a Chinese car with a Toyota badge, and Europe was never going to get it.
- The BMW comparison is the sharp one: Europe's iX3 does hands-off 130 km/h on motorways under UN R171; China's iX3 runs Momenta, is better in a city, and keeps your hands on the wheel. Two regulators, two shapes of permission.
- Verdict: the strongest evidence yet that Toyota's caution in the West is about liability and brand rather than belief — and an open question about whether the “Level 2++” system promised for 2028 will be Toyota's at all.
How does it stack up? Put the Chinese Toyota next to the American one, or set it against the Xiaomi YU7 and the BMW iX3.
