Paris - The possible sharing of General Motors' OnStar technology is part of the broader collaboration talks between the US automaker and PSA/Peugeot-Citroen, a senior PSA executive said Friday.

"Of course it's part of the discussion," said Marc Duval Destin, PSA's vice president, automotive research and advanced engineering.  Duval Destin, in an interview with automotiveIT, declined to go into more detail, but noted that GM's emergency calling system, which is available across North America and in China, has been "a big success."

OnStar has more than 6 million subscribers and is available on more than 45 GM models. The carmaker also offers an aftermarket mirror solution that is available to non-GM vehicles as well.

PSA and GM earlier this year announced a major alliance aimed at saving the two companies 2 billion dlrs a year. The two companies are discussing a range of projects, including the sharing of car platforms and engines. As part of the agreement, GM acquired a 7 pc stake in PSA.

OnStar is also of interest to GM's German Opel brand, which, like PSA is facing a likely 2015 deadline to implement eCall, a mandatory Europe-wide emergency calling system.

To help meet this deadline, GM officials said Opel may get a version of OnStar in Europe in 2015 or 2016, but no final decision has been made.
