Waymo has its sights set on its next robotaxi: the Hyundai Ioniq 5.

The Alphabet company announced that it was entering a “multi-year, strategic” partnership with the Hyundai Motor Group that will result in the Ioniq 5 eventually joining its robotaxi fleet.

But first, the Ioniq 5 will need to undergo on-road testing with Waymo’s self-driving technology, which the company says will begin in late 2025. Waymo wouldn’t specify when the Ioniq 5 will be used for passenger trips, except to say it would be “years” later.

Vehicles intended for Waymo’s fleet will be manufactured at Hyundai’s $7.6 billion Metaplant factory in Georgia, which is nearing the end of its construction. The companies have agreed to produce a number of Waymo-equipped electric Hyundais there “in significant volume over multiple years,” Waymo said in its press release.

With robotaxis, one of the most important metrics is uptime, or the amount of time it’s on the road ferrying passengers. Time spent plugged into a charger is time not making money. The Ioniq 5 is an electric crossover SUV with a little over 300 miles of range and an 800-volt architecture that enhances its charging speed. When plugged into a 350kW fast charger, Hyundai says the Ioniq 5 can charge from 10–80 percent in just 18 minutes, depending on the conditions. Waymo certainly saw those charging speeds as a benefit to its still unprofitable business.

The Ioniq 5 has received favorable reviews since it was released in late 2021, in addition to raking in numerous awards. Today, it’s one of the bestselling EVs on the market, with 30,000 sold in the US this year alone. Its popularity has helped Hyundai, along with its sister company Kia, overtake Ford and GM as the No. 2 seller of EVs in the US behind Tesla.

Currently, Waymo operates a fleet of hundreds of Jaguar I-Pace vehicles, which has been its primary robotaxi vehicle since the company’s first one, the Chrysler Pacifica minivan, was retired in 2013. The company has plans to add a new vehicle made by Geely’s Zeekr — though the Biden administration’s recent move to quadruple tariffs for electric vehicles imported from China could complicate that.

Recent reporting from South Korea previewed today’s partnership news, with sources telling Electronic Times that the two companies met numerous times at Waymo’s headquarters in California to discuss “contract manufacturing of robotaxis.” Sources also told the publication that Waymo was looking for a “replacement” for its Zeekr vehicles because of costly new tariffs.

But Waymo pushed back against this report and reiterated its intention to eventually deploy Zeekr. “The IONIQ 5 will not directly replace any of our vehicle platforms, but it will help us prepare for additional scale and growth opportunities,” Waymo spokesperson Christopher Bonelli said in an email. Waymo is “hard at work” validating the sixth version of its self-driving technology in the Zeekr vehicle, he added.

Tellingly, Waymo isn’t saying how many Ioniq 5s it plans to buy from Hyundai, in contrast to its approach to previous vehicle announcements. Some of this could be attributable to the fact that Waymo has grown more cautious about overly optimistic predictions after critics panned the AV industry for setting unrealistic deadlines.

This won’t be the Ioniq 5’s first self-driving rodeo. The vehicle also serves as a platform for Motional, which is Hyundai’s robotaxi subsidiary, as well as Avride, which used to be Yandex’s self-driving group.

But Waymo’s business is significantly, well, busier than those firms. The company recently celebrated a significant milestone: 100,000 paid trips a week.
