I can tell a difference between regular and power mode in the transmission shift points and mileage. Power mode is good for a 1.5 to 2 MPG drop over regular mode. Most likely, this is caused by power mode raising the shift points in the lower gears. I drive in regular mode most of the time.

 

 

I only use the Power mode when I'm in moderate traffic to make quick lane changes or if I have to haul a**. Gas is just too much to be driving in Power mode all the time.

 

Any CL members drive with snow mode that can give us some verdict? :P

 

It works great for the snow. It seems to get a little better gas mileage, however I just don't like the power loss to drive full time in snow. Imagine no power and shifting in final drive at 40mph.

 

normally in normal mode but switch to power and snow depending on the conditions. hopefully i wont have to switch to snow till next winter.

 

i keep it on power unless im goin on a long trip then switch to normal. i switch the VSC off when i wanna do alittle burnout teehee

 

I forgot about the power mode. Need to try it out.

 

Just like the rest, I normally keep it in Normal Mode when cruising and trying to save gas. Power Mode when up for spirited driving or trying to pass or launch from a dig.

I hardly ever use snow mode.

 

Does SNOW MODE save gas ? I would like to know

Used power mode once, If I wanna drive fast or race i'll jump in my brothers e46 m3

 

The GS is actually a very heavy car, I don't know if the power mode helps at all.

I am jealous of the GS4 with V8s....

 

Do you think that will make a difference. Will the car run too slow.

If it does make a difference I would consider it for commute driving

 

I DEFINITELY think it makes a difference...
Try it, you'll feel it..your car wont pickup as quick..it will feel bulky...

Uusually when I drive..I am heavy on the gas pedal...So when it is in snow mode..the pickup isn't as responsive...So I am sure there is less fuel being used...

I haven't kept it on for a full tank to actually realize how much difference it makes...but I know for sure if I were to keep it on snow mode and not floor it like I usually do It would be a lot more economical! Not safe for changing lanes in traffic though!

 

Recently I started using Power mode more often and the gas mileage improved. But that's also I change the way I drive. Since GS is such a heavy car, so I opt for Power mode to quickly pick up the speed, and then cruise by easing on the gas paddle. This works some what in regular city/hwy driving. In heavy traffic, snow mode helps a bit, but the car also becomes a whale. Anyway, I am talking about 1 mpg difference here so it could be the weather.

 

I mostly use the power mode
