Epsilon platform and the new 9-3 was due to come off the Epsilon II that underpins the new

and, of course, the Volt. If the new plan, proceeds that would give
two cars off the new chassis with the smaller 9-1 being the other. New structural construction technology in the new architecture will apparently help maximize interior space in the smaller car.
