After seeing plenty of shots of Opel's new Insignia mid-sizer, we're anxiously awaiting General Motor's official announcement of its statewide debut as the next-gen Saturn Aura. Unfortunately, current rumors indicate that we'll be waiting a bit longer than initially planned, as the project has reportedly been put on hold for an undetermined amount of time. We're fuzzy on what prompted the hold-up, though some conjecture has been heard regarding the fuel economy of the impending vehicle. In Europe, there are four gasoline engines and three diesels available, though we have serious doubts that many if any of those powerplants will make it Stateside. It's certainly possible that today's high fuel prices are causing GM to rethink getting one of its smaller gas engines certified for sale in the U.S. We can be sure, though, that this expected new vehicle launch will be an important one for the future of the Saturn brand, so perhaps GM is wise to get everything sorted out before its official debut
