#134 of 163 That would be nice

Actually, since the new Vue two-mode uses the 3.6l (if I remember what I read?), it doesn't seem like too much of a stretch to see this making its way into the passenger cars in the not-to-distant future. The Vue uses a transverse mounted engine, and I think the new two-mode is front-drive only. So the transmission and engine layout are there. The only question is whether the package would fit under the Aura / 'bu hood, and possibly where to put the batteries..
And for all the griping about 'only 2 mpg'- 10% better without changing your driving habits and locale isn't anything to sneeze at. Sure, I can (and routinely do) get 10-15% better than most people in similar vehicles on the same route I drive, but that's driving the speed limit, anticipating slowdowns / speedups (egg-under the accelerator method), etc. Add another 2 mpg for the mild-hybrid at very little up front cost, and things look pretty good. All without the relatively large compromises being made for the competition's full hybrids (lost trunk space- Camry, lurching- Camry, weird packaging- Prius, heavy dependence on the batteries for overall results- both Camry and Prius).
Don't get me wrong here, those compromises are fine if the end result of the maximum fuel savings is your goal, but most of us out here would like to not pay an arm and a leg for the car, or give up space (it's a PASSENGER car for a reason), or be able to carry 4 folks and their luggage on a trip, or even deal with strange drivetrain feel daily. To each his own. The mild hybrid is a good way to maximize existing powertrain efficiency without extreme expense or any real sacrifice in the capability of the platform in question.

Regarding the 2008 Malibu mild hybrid, there's a bit more to the "why bother?" question than the EPA estimated 2 mpg increase.
Caveat: I've never owned a GM product nor work for any car industry concern.
+ Mild hybrids like the design in the Malibu and Aura are relatively simple when compared to dual-mode hybrids. The reduced system complexity and small size of mild-hybrid components (its electric motor-generator (MG) fits in the ICE-only Malibu's alternator position) means that many car models could add the mild-hybrid feature.
+ The main fuel-saving strategy is to cut fuel supply when the engine is not powering motion, i.e. at rest (auto-stop) and deceleration (regenerative braking).
+ A minor benefit to regenerative braking is decreased use of brakes, thereby promising a maintenance savings for those components.
+ The MG is used for power assist during acceleration. While it is nothing like a performance hybrid Lexus or Accord, the mild hybrid should have equivalent pick-up to its ICE-only cousin despite a bit more weight. If the stars align, it could have marginally better acceleration or improved fuel economy during acceleration, or both.
Here's a link to an SAE article about the GM mild hybrid system as included in the 2007 VUE. From what I've read about the Aura and Malibu mild hybrids, they are very similar.

Anyone know the count of Malibu Hybrids sold?
I'll bet not much.
meanwhile the Toyot Prius and Camry Hybrid are selling pretty well.

Can't buy them if the dealers don't have them.I have not seen a single Aura or Malibu hybrid at a local dealer.

actually there is one guy reporting on his new MH who loves the car.
he's impressed with his gas milege of 30 mpg on his 2.4 litre 4 cyl. hybrid

I haven't looked on the fueleconomy.gov website to verify this, but the mild hybrids should have an advantage that appeals to most 'greenie' eco-friendly types, in that it shuts the engine down at a stop. This should greatly reduce emissions for the average driver over other four cylinder cars, and is painless, since the car is taking car of all the work itself. (I do the same in my vehicles manually, any time I'm stopped for any extended period of time- as at train crossings, long slow lights, in line at fast food places, etc.)

"actually there is one guy reporting on his new MH who loves the car.

FWIW, I'm getting 31 MPG in my AWD FEH hybrid, which is an SUV rather than a passenger car... thus not super impressed by that MH number. The FWD version is rated at 34 city.

"mild hybrids should have an advantage"
as opposed to non hybrids?

Yes. As opposed to non hybrids. Sorry if that was unclear.

Very impressive I was getting between 32 and 37 mpg on straight highway driving
on my old 2004 V6 200 hp Malibu, anyone who is looking for a great used car with great highway mileage get your hands on the V6 200 hp Malibu you will not be disapointed whats so ever. Just dont get it for city driving it averaged 15 to 16 mpg.
My car had the trip computer take one for test ride on a highyway and set the computer within 10 miles you will be in the 30's I also use to check the gas mileage manually and it was the same
