MDS at Idle?

[machz]

My e-torque is I believe, set at 2 seconds for all shutdowns while the Transmission is in drive. I am seeing the MPG keep moving up and the average is now about 17.1 MPG. The only thing I have found annoying with this so far is when traffic comes to a stop for 2 seconds using the Adaptive Cruise. When the car in front of me starts moving away the engine restarts but it doesn't start the vehicle moving until you hit the resume or the gas pedal.

Yeah, my Audi and my wife's Subaru does this. I wouldn't be surprised if it was some sort of federal regulation.

Chevy thought of this concept already and took it a step further so that you could be in 4-cylinder mode all the time. Yes, thats right, all the time. They achieved this feat not by updating the cylinder deactivation software for the 5.3 or 6.2, but just went ahead and put a 2.7L 4 banger in the Silverado. Never have to worry about running on all 8 cylinders if half of them aren't there!

I realize that this is sarcasm, but Chevy actually did update their cylinder deactivation using Delphi's Dynamic Skip Fire tech. (Chevy calls it Dynamic Fuel Management.) It's an intriguing idea. Instead of running in either four- or eight-cylinder mode, it adjusts firing such that the engine can effectively run on any number of cylinders (and even a fractional number of cylinders). On the V8 it's supposed to improve efficiency by 5 – 10%.

Yes and actually the turbo 4 banger drops to 2 cylinders as well.

According to my Scangauge, my 5.7L uses 0.3 gallons per hour while idling, once engine and transmission are at operating temperature.
That's 42.6 fl oz or just about 2.5 pints of gas.

Sounds too good to be true. MPG meter falls off a cliff in my truck when idling for 5+ minutes.

Don't think so. Tesla's adaptive cruise will automatically resume. I think my wife's Kia might as well - would have to double check though. I think some OEMs are just more cautious than others with implementing these driver assist systems.

I can tell you the Kia Telluride does not. Most vehicles have level 1 that is basic driver assistance. The tesla is between 2 and 3 and that's why it can restart. Even my 18 S5 is only between 1-2. It all has to do with the equipment installed on the vehicle.
