Germany's Spiegel magazine and Frankfurter Allgemeine Zeitung business daily reported that GM has decided to move development of the next Opel Zafira minivan from Germany to France. Opel's CEO Karl Friedrich Stracke denied the reports.

"As part of the initial announcement earlier this year, GM/Opel and PSA stated their intent to cooperate in several areas including product development. Whatever the final split will be among the agreed common projects, no jobs will be lost in the engineering center in Ruesselsheim due to the alliance – in fact, the nature of the alliance is that it is a balanced one," Stracke said in the statement.

"Opel is leaving no stone unturned to enhance the efficiency and future viability in order to achieve sustainable profitability as quickly as possible in a difficult market environment," he added.

GM and PSA Peugeot-Citroën are said to have sealed several deals over the past month, including expanding the number of cars they will build on shared platforms.

"Work teams are in place, meeting regularly and hopefully soon we will be able to share the first update on alliance progress," GM stated.

"We will launch a D-segment car, a crossover, a compact minivan, and two models in the B and C segments," he told the Italian daily. "After that, we will launch a shared-platform eco-friendly car."
