Self-driving car company Waymo and Fiat Chrysler Automobiles are expanding their autonomous vehicle partnership to commercial vehicles and Fiat Chrysler will develop fully self-driving vehicles exclusively with Waymo going forward, the companies said on Wednesday. Waymo, a unit of Google parent Alphabet, and Fiat Chrysler said they will work together to develop autonomous light commercial vehicles for moving goods, starting by integrating Waymo's self-driving technology into Ram ProMaster vans, which Fiat Chrysler sells globally. Waymo's autonomous goods delivery unit will use vehicles co-developed with Fiat Chrysler, the companies said. Self-driving vehicle companies and automakers have been shifting investment and engineering to delivery and other commercial uses of autonomous vehicles, betting that moving goods will offer a faster route to profits than overcoming the technical, social and regulatory obstacles to moving people. Fiat Chrysler is ending work on autonomous commercial vehicles it began in 2019 with start-up Aurora. Aurora is continuing to use Chrysler minivans in its test fleets, and said in a statement that it "looks forward to deploying our self-driving solution on FCA's passenger and commercial vehicles". In a blog post, Waymo and Fiat Chrysler said they will collaborate on "level 4" autonomous driving, a reference to a Society of Automotive Engineers classification that defines such vehicles as capable of driving themselves and taking action on their own if a dangerous situation occurs or the system fails. Waymo has been working with Fiat Chrysler since 2016 to integrate its self-driving vehicle system, the Waymo Driver, into vehicles such as the Chrysler Pacifica minivan. The expanded partnership with Fiat Chrysler will cover "ride-hailing, commercial delivery, and personal-use vehicles around the world," Waymo chief executive John Krafcik said in a statement. Fiat Chrysler's chief executive, Mike Manley, said in a statement the automaker intends to deploy Waymo's technology "across our entire product portfolio". The companies didn't say when new, autonomous vehicles will launch. Fiat Chrysler also has a partnership with BMW and Intel to develop automated driving technology.
