The head of BMW has suggested he would like to “strengthen” the Munich-based firm’s alliance with Toyota, pushing it beyond 2025.

According to Automotive News Europe, BMW CEO Oliver Zipse told the Automobilwoche congress he sees the alliance stretching years into the future.

"In the next decades, we would do well to strengthen bonds," Zipse said.

The BMW Group and Toyota first agreed to form a “medium-to-long-term collaborative relationship” back in December 2011. The tie-up between the German and Japanese automakers is currently centred on the co-development of sportscars (in this case, the Z4 roadster and GR Supra) and fuel cells. 

In addition, Automotive News Europe reports Zipse revealed BMW was considering cutting back its product portfolio in a bid to reduce costs.

"Coupés, convertibles and roadsters; we will see what will be left," Zipse said.
