An unanswered question from last week's General Motors and PSA Peugeot Citroen deal is how the alliance will affect GM's product-development centers around the world.
Take, for example, GM's center in Korea, which develops platforms for the company's minicars, such as the Chevrolet Spark, and subcompacts, such as the Chevrolet Sonic.
For much of the past decade GM relied on multiple subcompact platforms engineered and sold in different markets. By 2010 that development work had shifted largely to GM Korea, formerly known as GM Daewoo Auto Technology Co.
But PSA specializes in subcompact cars. How will the alliance divvy up engineering and development work between the two companies for subcompacts? For now, the automakers are mum on the question.
A GM spokesman said: "No decisions have been made on any specific vehicles."
