The Saturn Green Line is no longer. In its stead, the planetary brand's hybrid models will simply be known as hybrids. We think this is a good idea considering that the word 'hybrid' is much more readily associated with saving gas than the Green Line moniker. According to Mike Morrissey, a Saturn spokesman, "It was simply a practical matter. As we expand our hybrid lineup, the names were getting a bit long. It's hard to write a short sentence about the Saturn Vue Green Line 2-Mode Hybrid." Amen to that. Though the Green Line name will disappear, the performance version of Saturn's models will retain their Red Line badges.
Saturn's current green line of hybrids includes two models, the Aura and the Vue, both equipped with the so-called "mild hybrid" system that is not capable of moving the vehicle under electric power alone. Next year, a version of the Vue utility vehicle will be offered with a system derived from what is currently available in the Tahoe and Yukon full-sizers known as the 2-Mode. That model will be a full hybrid and should return much better mileage than the current Vue hybrid, which is rated at 25 mpg in the city and 32 on the highway.
Shortly after reports of leaky batteries coming from Cobasys, which greatly slowed the production of GM's mild hybrid vehicles, such as the Saturn Vue and Aura hybrids and Chevy Malibu hybrid, comes a report from Automotive News which suggests that General Motors may just purchase the troubled battery maker outright. That's one way to manage the problem, wouldn't you say? Though GM would own 100-percent of Cobasys, some sort of partnership is said to be in the works, though that other entity remains unknown. Before this announcement, Chevron and Energy Conversion Devices, co-owners of the battery supplier, had been fighting over ownership of the company.
What effect this news may have on GM's future hybrid plans remains unknown. Currently, Cobasys supplies nickel metal hydride batteries to the General. The upcoming Chevy Volt will use the newer lithium ion batteries. Still, General Motors recently showed off a new version of its mild hybrid technology, and therefore may have extended plans for future batteries from Cobasys.
As much as General Motors would like to sell more hybrids, we'd imagine it would be pretty tough to do so without having the batteries on hand. It turns out that since December of last year, GM has had to recall some nine-thousand battery packs produced by its supplier, Cobasys, which were due for installation in mild hybrid versions of the Chevrolet Malibu, Saturn Vue and Saturn Aura. The culprit was reportedly an internal leak in the pack which caused the entire unit to be inoperable. This setback hurts even more in the face of record gasoline prices and the resultant record sales of hybrid vehicles.
Chevrolet plans to begin production of the 2009 Malibu hybrid on June 23. Cobasys says that it has resolved the leaky battery problem and that current units are shipping without defects. Unfortunately, some damage has already been done, especially for the Saturn brand, as sales of the hybrid version of the Vue have gone down from 2,683 units by this time last year to just 326 units thus far this year to go along with just 69 retail sales of the Aura hybrid.
