Google and Fiat Chrysler have agreed to work together to build a fleet of 100 self-driving minivans in the most advanced collaboration to date between Silicon Valley and a traditional carmaker.

The deal marks the first time Google has worked directly with an automaker to integrate its self-driving system, including its sensors and software, into a passenger vehicle, the companies said in a statement.
Google's self-driving car engineers had previously purchased Lexus sport utility vehicles made by Toyota Motor and retrofitted sensors and other hardware into the cars on their own.
Fiat Chrysler and Google engineers will work together to fit Google's autonomous driving technology into the Pacifica minivan from the vehicle's conception.
Google said it is not sharing proprietary self-driving vehicle technology with Fiat Chrysler, however, and the vehicles will not be offered for sale to the public.
The Fiat Chrysler vehicles will more than double Google's testing fleet, which currently includes about 70 Lexus SUVs and small prototype cars designed by Google. Google is now testing self-driving vehicles in four US cities.
Google has said it does not want to build self-driving vehicles on its own and has explored alliances with auto companies, but none have been finalised. Working more closely with Fiat Chrysler could help Google refine its systems as a step toward offering them in regular production cars.
The agreement between Google and Fiat Chrysler comes as rival technology and auto companies are accelerating efforts to master the complex hardware and artificial intelligence systems required to allow vehicles to pilot themselves.
General Motors in March agreed to acquire San Francisco self-driving car startup Cruise Automation . German automakers Daimler, BMW and Volkswagen last year bought digital mapping company Here to accelerate their autonomous driving development.
Some features already available on mass market cars like SUVs and trucks take steps in the direction of replacing a human driver, such as automatic emergency braking, adaptive cruise control and automatic lane-keeping.
Some analysts said a self-driving minivan would make sense for testing the technology in a fleet of mass transit vehicles deployed in a controlled environment, such as a Google or Fiat Chrysler campus or a city centre.
“Minivans fit into the transportation fleets easily,” said Karl Brauer, a senior analyst at Kelley Blue Book. “They can be a box-on-wheels and can move more humans around.”
The deal does not preclude either FCA or Google from cooperating with others, the companies said in their statement.
“The opportunity to work closely with FCA engineers will accelerate our efforts to develop a fully self-driving car that will make our roads safer and bring everyday destinations within reach for those who cannot drive,” John Krafcik, chief executive of the Google self-driving car project, said in a statement.
Executives at other automakers, including GM, Ford and Daimler, have expressed wariness about alliances with Alphabet or other technology companies that could relegate them to the role of hardware suppliers.
John Elkann, Fiat Chrysler's chairman, in April dismissed the idea that automakers must shoulder alone the burdens of heavy investments in automated driving or ride sharing. By 2030, Elkann said, fully self-driving cars will likely account for just 15 percent of global sales.
"Boring old car makers need to figure out how to make this profitable and guard against falling into the ... trap of ignoring that business while chasing profits in other parts of the value chain," Elkann said.
