Perhaps that was a mistake, but if that's true, it's just about impossible--in ANY car of this size, hybrid or not. That's a full 14.5 mpg LOWER than the EPA estimate. You truly have to try VERY hard to achieve that kind of dismal result.
This is again why I try to point out that your particular car, or some combination of your commute and driving style is leading to this result. It is NOT the norm for the GL, and if Saturn was able to produce decent MPG when it was in their hands, there is little left to blame when it comes to the car.

You're right - my fault on the typo - it was 90 city 10 highway so too quick on the fingers, now corrected. It's true - we can get high 20's on highway cruising as you can see so no real issue there except it's really not the BAS doing that.
My point is that, if it's possible to regularly achieve under 20 on mostly suburban commute, that's appalling. If a complete driver retraining is required to get anywhere close to Saturn's city, then shame on them, as I bet the same would apply to any regular gas car. If that's the case, it can only be concluded that the BAS is worthless for the majority of users from a fuel economy perspective.
By the way, I did have Saturn do some extensive city testing under similar circumstances as us and they got 20/21. They kept poor records so I couldn't document that here, so apparently they have a driving style that yields much the same.
The thing about technology is that if it takes so much retraining to use it, it won't stick around as people want to go about their everyday lives without having to worry about whether they're optimizing the technology they're using. Under real world condidtion, I think the BAS is falling into that category - not worth bothering with
