Back in September, BMW CEO Norbert Reithofer announced an ambitious plan to increase production to 1.8 million vehicles by 2012 and to 2 million units by 2020. To reach those goals, BMW is planning several new niche models, including what it referred to as a "Progressive Activity Sedan". But while little in the way of details for the PAS were revealed at the time, a video has surfaced revealing a test mule for the car, which will be based on the next 5-Series with a fastback body-style.

The PAS is anticipated to slot between the 5-Series sedan and 5-Series wagon, with five seats and a hatchback rear end. Currently undergoing testing, the PAS is expected to go into production in 2009 or 2010 after an unveiling as a concept either at the Paris show later this year or in Detroit a year from now. Check out the video after the jump.
