CONFIRMED:
VUE: The Vue will add a second Green Line hybrid model for 2009; this one will get a 3.6 liter V6 with GM's Two Mode hybrid system, the first such use of the Two Mode system in a front-wheel-drive vehicle.
RUMORED:
ASTRA: Though the current Astra was just introduced in the US for 2008, the Opel Astra on which it is based dates from 2004, and a new version of the Astra should be joining the Opel lineup within the next year or two. Once that happens, we expect a Saturn version to follow soon after.
Next: Subaru
