Have just about 4,000 miles on it now since May and I have yet to have a chance to drive it in heavy rain, it's just been mostly drizzle and light showers. But today, got a good wind driven soaking. Hit the back roads and the highway for a while, drove like I normally would in the rain, the car handled well, I noticed no difference from my '10 GS.

Did you use the "Weather" mode for your driving in the rain Norm?

Did you use the "Weather" mode for your driving in the rain Norm?

Duhhh, dummy me did not even think about using any of the modes, I leave it in the sport mode and just forget about it. I did some mild goosing a few times, straight as an arrow. Will change modes next time to see if any difference.

I found on those rare occasions when we have gotten rain or when I drove through Texas heavy duty rain storms on the way back from NCM, the Weather Mode made it a bit easier to concentrate on driving. My perceptions included slowed throttle response and smoother braking with it on.

After my first trip through the rain, I took it to the car wash and said "Be gentle it's her first time"! LOL

 

[53Vette]

Is it just me or does anyone else think Weather and Eco should be the same mode? V4, slow throttle, wouldn't that work for both modes?

Funny you mention that, since the only time I got caught in the rain was on the highway (while in ECO) and I never even thought of putting the C7 in the Weather mode.

Weather mode is always V8 with the 7 speed...

Weather mode interacts with the Traction Control/ABS as well, while ECO does not. ECO does not impact Throttle progression as does Weather. On the other hand Weather does not impact Active Fuel Management differently than other setting except ECO, which puts it in ECO mode. So they are designed for different outcomes.

In Eco mode does the engine always use the same four cylinders or does it rotate the cylinders periodically so all receive the same amount of wear?

Thanks for clarifying.

Always shuts down the same 4: From GM "Active Fuel Management (AFM), which shuts down the LT1′s firing cylinders from eight to four by disabling the valves to the cylinders, also brings the efficiency of the 6.2L pushrod motor to never-before-seen heights. When AFM commences, the engine turns the 6.2L V8 into a 3.1L V4, shutting down cylinders 1, 4, 6 and 7, and firing only cylinders 8, 2, 5 and 3 in that order. Otherwise, the complete firing order is 1, 8, 7, 2, 6, 5, 4, 3."

When you drive in heavy rain does a lot of water, grit, mud, etc come up from the road and wheels and enter the engine compartment? I am thinking of those folks that show their StingRay and who have the chrome/carbon fiber/custom painted accessories under the hood. What does it look like after driving in water? Just curious.

I was in light rain for about an hour on the highway. The engine compartment remained clean.

Did you happen to be North of Philadelphia today near Montgomeryville?

I might have seen your car today at lunch.

 

[Tom0021]

I too drove in the rain today. Put the car in Weather mode. Started out on the highway for the first half of my hour drive into the office. I did hydroplane at one point in very heavy downpour. Car was great as the controls kicked in faster than I could respond. Speed was 53 mph just hit a low spot on the highway. Tire pressure was at 28 psi on all four.

At the exit from the highway was stopped, I was on the inner lane turning left as it was two lanes wide. When the light turned green started the turn when person on the outside cut the turn short and drifted into my lane, I just made a tighter turn, back end made a slight movement and the nannies kicked in. I was very impressed at how the controls worked, the speed that they activated.

I drive an hour each way to the office today, heavy, medium and light rain for the commute both in the morning and return in the evening.
Looks nice and clean to me.

No not me, Lower, Slower DE. I'm seeing a few more AW C7's in the area, getting quite popular.

 

[c7pilot]

I may never get a chance to use the weather mode here in California since we only got 5" all last season here on the Central Coast. Still waiting for my 2015 CRT Coupe , A8, 2LT. NPP, CHROME wheels.

Nice and clean indeed! Thanks for the picture--it says it all.

 

[thrilled]

I doubt I will ever take it out of Sport.I don't drive it in the rain.I bought 8 cylinders,I'm going to use 8 cylinders

Thanks for clarifying.

Jeff pretty well gave you the details, but it is worth noting that there is no "less" wear in this mode. All cylinders still move on the crankshaft even though those cylinders are not producing power.

On the rain topic; There is rain, and then there is RAIN like some cities / areas got yesterday. Here in parts of central Va. we got 3"-4" of rain in less than 1 hour. People were loading up animals 2 x 2!
