The General Motors Europe design center's main task is creating Opel, Vauxhall and Saab products based on architectures for which GM Europe is the global leader.
These are the upper-medium and lower-medium architectures formerly known as Epsilon and Delta.
"We will drop the Greek names for architectures," said GM Europe spokesman Stephen Janisse. GM Europe has global r&d responsibility for the two architectures, known inside GM as medium (Opel/Vauxhall Vectra and Saab 9-3) and compact (Opel/Vauxhall Astra).
Korean affiliate GM Daewoo is responsible for lower-medium SUVs, and may get small cars as well.
Within the global network, GM Europe also will design for GM brands in other regions, such as Saturn in the US. GM says that won't lead to badge engineering.
"While Astra has a typical European hatchback body style, a Saturn version could be a typical sedan," said Bryan Nesbitt, executive director of GM Europe design.
"That's just like Volkswagen differentiates the Golf and Jetta for the European and US markets."
