Replying to: logic1 (Apr 05, 2006 1:16 pm) What kind of MPG did you get from that $38,000 CTS, as compared to the MPG from the $25,000 VUE? I don't think these two vehicles can be compared.

Replying to: scottnewvue (Apr 05, 2006 1:16 pm) Here is a partial repost of #16 of this forum. The bottom line is that this system does not provide propulsion at all. It does releive the engine from powering an alternator, which provides a small boost in torque. It is my understanding that the GMC Sierra uses large batteries, not this system. I haven't heard of it's use before the Green Line Vue. http://tinyurl.com/btnu2 "How Does It Work? The BAS concept is to replace the belt driven alternator with an electric motor that serve as a generator and a motor. Thus when the engine is running the motor, and acting as a generator, the system will charge a separate 36 volt battery. When the engine needs to be started, the motor then applies its torque via the accessory belt, and cranks the engine instead of using the starter motor. In this scheme, the motor/generator can be made larger than a standard starter motor so more torque can be generated when in the motoring mode. This allows for quicker starts of the engine, and makes the start/stop operation possible. Stopping the engine while vehicle is at idle is a means to conserve fuel. The disadvantage to this type of system is that you notice the engine starting and stopping. The control system for this technology so far has been somewhat crude in comparison to the full hybrid engine startups and for some people it could be annoying.

Replying to: stevedebi (Apr 05, 2006 2:10 pm) MPGs were around the same. I was more agressive but doing more open road driving with the CTS. The 3.6 in a slightly modified form will be available in the Aura. I expect it will go on to become the V6 option for the next VUE. The hybrid, on the other hand, will have the 2.4 litre 4 used in the Solstice and Sky, an engine not available when you bought. |

Replying to: stevedebi (Apr 05, 2006 2:15 pm) We went over this earlier. According to GM, the electric engine in the Green line will provide acceleration boost and take over when one brakes to decelerate. The disadvantage to this type of system is that you notice the engine starting and stopping. I have read several reviews from people who have actually driven the Green Line. They say stop and start up is barely noticeable.

Replying to: logic1 (Apr 05, 2006 2:56 pm) Do you happen to have a NON GM source for this statement? I'm wondering if it was GM engineering or GM marketing that made this statement. RE: Acceleration boost. Since there are no electric motors connected to the transmission, I don't see how this is supposed to occur. Unless they are referring to the fact that the engine doesn't have to turn the alternator. At the moment my trust of GM is rather sparse, considering their current business situation. RE: Braking. This one makes sense, the system is connected to the engine via a belt, so it could provide some drag as it charges the battery.

Replying to: stevedebi (Apr 05, 2006 4:19 pm) Oh that makes a lot of sense, I should have a third party source for a vehicle not already on the market. I don't see how this is supposed to occur. Unless they are referring to the fact that the engine doesn't have to turn the alternator. So then you do have a hybrid Vue. At the moment my trust of GM is rather sparse, considering their current business situation. Another real sensible statement. GM has to pay a lot of retirement money so we cannot trust their product statements. By the way, I can read all words, whether bold, all caps or not. |

Replying to: logic1 (Apr 05, 2006 1:16 pm) Buy a Honda or Toyota and you get basically the same engine that's in a Lexus or Acura. If GM put their best technology in all their vehicles, their sales wouldn't be nose diving. I understand the issues GM has with legacy expense added on to the cost of each vehicle. That is a problem the government should have addressed with universal health care, etc. The consumer does not want to subsidize a manufacturer for poor management or government policies. They just want the best product. I don't see the Saturn GreenLine as a groundbreaking product. It's technology is at least 3 years behind the curve. If the GreenLine had the new 6 speed transmission, I'd consider buying one. We will see in a few months when the road tests and consumer reports come out, who's right about this. It looks like GM is on the right Track with the Saturn Outlook and Aura. They will have the 3.6 engine with a 6 speed transmission.

Replying to: ems1 (Apr 06, 2006 6:32 am) But GM is not promoting the VUE Greenline as ground breaking. It is promoting it as a hybrid option that will not add extensively to the base price of the product, but will nevertheless get gas mileage equal to best in its class. If the GreenLine had the new 6 speed transmission, I'd consider buying one. So what you are saying is the cost of the Greenline, and its mpgs compared to the competition mean nothing. But being able to say it has six speeds, well that is a world of joy. I went through this myself. When I bought my second (NB) Miata, I opted up for the six speed manual. It was a waste. I almost never used the sixth gear, I did not get better mileage than those who bought the base with the 5 speed, and it did not shift any better. If technology improves consumer experience, I am all for it. But unless you can show the lack of a six speed automatic is hindering the Greenline's stated purpose, I do not see the point of your objection. It looks like GM is on the right Track with the Saturn Outlook and Aura. They will have the 3.6 engine with a 6 speed transmission. And they will cost a lot more as well.

Replying to: logic1 (Apr 06, 2006 7:40 am) The jury is still out on whether the GreenLine will be cost effective. We will have to see what the real world mileage is. You have to drive most hybrids over 100,000 miles to, at least, break even. If the Vue has a payback at less than 50,000 miles, I guess that would be a success. I think most people want leading edge technology, whether it makes their life better or not. I guess that is just human nature. Would I rather have a 5 or 6 speed transmission over a 4 speed? YES. I don't want old technology in my cell phone, TV, car or even a refrigerator.
