Germany's Adam Opel will in future develop all of parent General Motors' mid-sized vehicles, Opel's chief executive was quoted as saying.

As part of a restructuring of GM's European activities, Opel will assume a central role in the mid-sized class, Welt am Sonntag said, citing Opel chief Carl-Peter Forster, according to Reuters.

"In the past we developed vehicles of the same class in several areas of the world. We do not want to continue to do so; this will be more strongly consolidated," the paper reportedly quoted Forster as saying.

According to Reuters, Forster said Opel should turn a profit this year.
