The alliance between car manufacturers Renault and Nissan will launch more than ten cars with self-driving technology over the next four years in the United States, Europe, China and Japan, the partnership's leader has announced.

Vehicles with self-driving technology will debut this year, said Carlos Ghosn, CEO of Renault and chairman of the Renault-Nissan alliance.

The cars will have a feature called ‘single-lane control’ that allows them to drive autonomously on motorways without switching lanes.

Renault-Nissan will also launch an app for mobile devices this year that allows users to interact remotely with their cars, such as by controlling music or the car's temperature.

By 2018, Mr Ghosn said the alliance will start selling vehicles with "multiple-lane control," meaning they can autonomously change lanes on motorways and navigate heavy traffic.

By 2020, the alliance will have cars that can drive through city junctions and heavy city traffic on their own.

Renault-Nissan is a partnership between Paris-based Renault and Japanese carmaker Nissan that combined the companies' engineering teams.

Both manufacturers still operate as separate companies.
