The head of General Motors' German unit Opel plans to achieve a 5% return on sales by 2016.

Germany's manager magazin, citing sources in the group, said chief executive Karl-Friedrich Stracke is already expecting the brand will break even in 2011, one year earlier than planned.

According to Reuters, manager magazin added that he expected Opel to increase sales volumes by 100,000 next year to around 1.4m vehicles.
