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.

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 got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 192,000 km to date.

Doubtful, I'm afraid. HCH-II pilots can "deadband" by taking their foot off the accelerator and then barely tapping it to kill regen, which results in a low-resistance and zero-fuel coast. However, at the root of that coasting ability is the fact that the HCH-II can shut all valves, which effictively allows the engine to freewheel since it is no longer trying to pump air. The Saturn would need that or a similar technology to do the same, and I have seen no evidence of it. Coasting in the Greenline should be just like taking your foot off the accelerator of any conventional automatic transmission vehicle.

This feature alone could change America's fuel consumption habits overnight....

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

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?

I agree. I agree. Iagree.

Crankshaft strength is not an issue. Ability of the electric machine to turn the crank could be an issue.

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 ?
