Adaptive Cruse Control Reduces MPG
So, I have been using the adaptive cruse control on my Nero Touring with Tech package and have found in most cases it reduces your MPG due to bad logic. Issue is that the car dose not smoothly accelerate or decelerate when objects enter into your patch, dispute changing the distance settings.
What happens is if you have your cruse set at 65 mph and there is a car in front of you traveling at 55 mph and that car then pulls out of hour path, rather than steadily increasing the speed to 65, the car just punches the accelerator, downshifts and gets to 65 as quickly as possible. Likewise if a call enters your path even with a safe distance, the cruse will apply braking to decrease your speed as quickly as possible to match that cars speed and distance. This being the case, the car operates almost erratically in anything other than limited traffic.
When you observe this effect over and extended time you can notice that the MPG is dramatically decreased and in some cases the driver efficiency rating will even show aggressive behavior.
I have used the Subaru adaptive cruse with their EyeSight and this is not the case. It leads me to think that there is a programming correction that is needed to remedy this issue.
All this being said, I have stopped using cruse except in very light traffic and can better manage the fuel economy by contorting speed manually.
Hope they release an update for this soom
