Volvo is one of the proponents of autonomous vehicles. On 20 November 2017, Uber announced that it planned to buy up to 24,000 Volvo cars designed to accept autonomous technology between 2019 and 2021. This non-binding intent includes a plan for Uber Advanced Technologies Group to design and build the self-driving system in the XC90 SUV vehicles. In 2016, the two companies had announced that they planned to collaborate on the design and financing of cars with self-driving systems. Such vehicles require a different type of steering and braking mechanism, as well as sensors. The CEO of Volvo Cars, Håkan Samuelsson, made this comment in an interview: "We get support developing this car ... It’s also a big commercial deal."
