The move would mark the most visible agreement since GM and PSA signed an alliance earlier this year and it could help turn around both of the struggling European automakers.
"[PSA] will get production models from General Motors in compensation under the alliance," Perrard said, indicating that the French automaker might wind up building a GM product or two.
An announcement could come as early as next week, the French paper reports, although Perrard indicated that a firm decision could be up to six months away.
PSA plans to invest around 40 million euros in Rennes, a plant that has seen its workforce cut in half over the last few years as PSA sales have tanked.
