Waymo Will Have Toyota Fit Its Driver at the Takaoka Plant, but Gives No Volume, Cost or Sensor Count
The bZ4X robotaxi is a supply answer for a fleet still built on a Jaguar that is out of production; Waymo's two posts six weeks apart also put its safety multiple at 15 and 20 times.
Waymo said on October 30 that the Toyota bZ4X will be its next robotaxi, built with Waymo's autonomous hardware installed on Toyota's own line at the Takaoka plant in Toyota City, Aichi Prefecture. Operations start in Japan in 2027 "to test and validate" the fleet, and the post gives no vehicle count, no price and no sensor specification.
The Waymo post describes the whole process happening in one location, from base-vehicle assembly to integrating the Waymo Driver, which Waymo rates as Level 4. Riders get extra rear legroom, automatic doors, a power liftgate and ambient lighting. The United Kingdom and other Waymo markets follow in later years, with no dates.
Why the factory is the point
The number that matters here is not the vehicle but where it is fitted. Electrek notes that Waymo's US fleet is mostly Jaguar I-Pace SUVs, a model Jaguar no longer produces, and that Waymo is adding the Zeekr-built Ojai van and the Hyundai Ioniq 5. Waymo reports more than half a million trips a week across 15 US cities. A fleet serving that volume, on a donor vehicle with no production line behind it, can grow only by retrofit or by switching platforms.
Factory integration removes the retrofit step. If the driver hardware goes in at Takaoka, the unit that leaves the plant is the unit that drives, and Toyota's line rate rather than a third-party upfitter becomes the ceiling. None of the sources gives that rate.
| Platform | Status per Electrek and Waymo | Volume stated |
|---|---|---|
| Jaguar I-Pace | Most of the US fleet; Jaguar no longer produces it | none |
| Zeekr Ojai van | Being added | none |
| Hyundai Ioniq 5 | Being added | up to 50,000 by 2028, reportedly in talks |
| Toyota bZ4X | Japan 2027, test and validation | none |
What Japan actually means in 2027
Waymo's September 14 post with taxi operator Nihon Kotsu and the GO app targets a commercial, driverless Tokyo service in 2027 that grows to around 100 vehicles. The launch depends on regulatory approval and on finishing validation. Read against that, the October announcement is a vehicle choice for a fleet that is small at first.

- Hyundai Ioniq 5, reported by Electrek50K vehicles
Source: Waymo Tokyo post, Sept. 14, 2026 (about 100); Electrek, Oct. 30, 2026 (up to 50,000, reported talks)
The two figures are not comparable: one is a Waymo service target, the other a reported supply discussion the posts we read do not confirm.
Two safety multiples, six weeks apart
The October post says Waymo is "up to 20 times safer than human drivers" for serious crash injuries where it operates. The September post puts it at over 15 times safer than human drivers. Both are Waymo's own claims. The posts we read do not say whether they use the same dataset, the same period or the same injury threshold, so the move from 15 to 20 cannot be read as improvement.
What Toyota gets, and what is still open
Waymo co-chief executive Dmitri Dolgov said in the post, "We chose Toyota because of our respect for the legendary safety, reliability, and quality of their vehicles." Hiroki Nakajima, a member of Toyota's board and executive vice president, said, "Safety technology makes the biggest difference when it reaches as many people as possible." The companies will also explore autonomy for personally owned Toyota vehicles; Electrek notes nothing concrete has been announced there.
The agreement builds on a preliminary April 2025 deal. Toyota and Pony.ai began mass-producing bZ4X-based robotaxis in China earlier in 2026, per Electrek, so the bZ4X is also the platform of a Waymo competitor. In the US the refreshed model sells as the Toyota bZ from $34,900; no source says what the Waymo version costs.
What would change this read is a stated Takaoka build rate or a sensor count per vehicle, either of which would turn a partnership into a capacity number. Until then, the next dated event is the 2027 Japan validation run.
For how another vehicle-adjacent maker is describing its output, see our report on Tesla's Optimus line, which also lacks a rate, and the robotics Section 232 proclamation, which covers a different product class from robotaxis.
