Why is the Boxster growing? To create room at the bottom of the Porsche lineup for a new two-seater based on the Volkswagen BlueSport concept shown at the Detroit auto show in 2009, the report says.

VW needs Porsche and Audi to sell versions of the BlueSport, along with a VW version, to make the project financially viable.

Porsche's incoming boss, Matthias Müller, comes from Volkswagen. We're pretty sure that will take care of any opposition from inside Porsche to the plan to grow the Boxster.
