Upcoming fuel economy
regulations in the U.S. and carbon dioxide emissions limits in Europe appear set to take a bite out of the next generation Saab 9-3
. The current 9-3
is derived from GM's
Epsilon platform and the new 9-3 was due to come off the Epsilon II that underpins the new Opel
Insignia, but a change may be in the works. GM has reportedly canceled the Epsilon II-based 9-3 in favor of a model built off the Global Compact Car platform that will be the basis of the next Astra
and, of course, the Volt. If the new plan, proceeds that would give Saab
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.
