Volvo Car Group says that it plans to launch a model with the capability of piloting itself down highways by 2021.

The Swedish automaker aims to begin conducting on-road tests in Gothenburg, London and China in 2017, with up to 100 test vehicles in each location.

Unlike other manufacturers that have announced that they will be developing self-driving technology in-house or in collaboration with third parties, Volvo maintains that it is still considering “various partnerships right now.”

Volvo Chief Executive Officer Hakan Samuelsson says “this technology is something as a carmaker you cannot develop by yourself” and that meeting its 2021 mandate will require Volvo to work with solution providers with expertise in software and cloud services.

Samuelsson also acknowledged that the company will need to contend with ever-changing laws that will adjust to remain in sync with advancements in technology.
