GM's 2008 'mild' Chevy Malibu hybrid?

Another GM 'mild' hybrid?

The 2008 Chevy Malibu hybrid will utilize the same hybrid powertrain as the Saturn Vue hybrid - a mild hybrid vehicle - rather than the dual mode hybrid powertrain which will power the upcoming Yukon hybrid according to battery maker Cobasys (press release).

It's great to see GM expanding its lineup of hybrid vehicles, but why isn't there more emphasis on the dual mode hybrid powertrain?
