Vauxhall models will be fitted with GM’s OnStar communications system from next year, according to the firm's European boss, Karl-Thomas Neumann.
The OnStar system, elements of which have been available in North American GM models since 1996, uses 4G technology integrated into the car to deliver a range of communication, navigation and safety services. The technology also offers in-car internet connectivity.
Vauxhall and Opel models equipped with the technology will have an SOS service which will connect the occupants to a live operator in the event of a crash. Similar emergency systems already exist in models from other manufacturers, including Peugeot, Citroën and Toyota.
A remote link function also allows the driver to communicate with the car to lock it or sound the horn in order to locate the vehicle in a car park.
Speaking at the Geneva motor show, Neumann confirmed the technology will be available on "nearly all trim levels".
