Re: Share what you know
Can't think of any reason that it would be limited to braking regen. If the alternator/starter is driven right off the crank then it will be spinning any time the engine is spinning. The pack should be fed whenever the SOC gets low, just like any other hybrid.

Re: Share what you know
i assume with the charge/assit meters, with the needle pointing in the middle is the coasting ability (since when one lets the foot off the gas, fuel injection ceases and it starts to regen... so the needle would sway to the left.... point being... hopefully one can add some gas pressure and the needle would swing towards the "assist" but a smart one would try to keep it between the two.)
also the ECO LIGHT is calibrated for the city mpg at lower speeds (27 mpg), and then calibrated for higher speeds on the highway. (32 mpg)
as for the A/C GM added a ECO button to limit A/C use if fuel efficency is a concern. (although not sure if the AC is electric or belt driven, i have a feeling that button limits the ability to stop/start if A/C is desired...)
from a test drive report one guy stopped, and the engine was killed, but as he shifted back to P the engine came back on alive and then he keyed off
from what I can tell, shifting into N does not kill the engine at all (B00!)
the engine will only be killed when the car is at absolute stopped. unlike the honda hybrids which start shutting down as you reach a lower speed. (then again as GM stated... fuel injection is ceased when throttle is not pressed)
that's it for now.

I remember seeing this featur about 10 years ago on a BMW 3 series thinking... who needs that gadget?

Re: Share what you know
Consumer Reports just gave the Vue a reliability rating of "Black Filled Circle", denoting "Much worse than average" reliability.
But then, this *is* a GM product. Did anyone expect QUALITY?

Why does the dashboard look so conventional?
It would not cost GM that much to display the instant mpg (and trip mpg, lifetime mpg...) - that inexpensive enhancement would sell and addict a lot more buyers. Besides, you want to know whats going on...

It sounds as if BAS torque would have to pass through the crankshaft to reach the wheels. This would limit torque or require a much stronger crankshaft and bearings, not a happy approach. But this also defines a distinct hybrid architecture, through the crankshaft. The IMA at least does not put any additional stress on this critical engine part.

Re: Share what you know
Martin can you give details on the VUE green line cold start operations? When starting on the car for the first time, does the car uses the 48 volt system or 12 volt system to start the engine? What are the limitations of the start/stop function of the car (like a minimum speed to enable the function)?
And finally can the car coast ?
