2018 Q4 with Fiamenghi Ti exhaust, Race Mod, and Tecnico wheels.
Then it sounds like your original statement "I don't know how do you get such mileage " is not really true, since you drive very aggressively in a Stelvio and most drivers would rather avoid the safety issues and penalties associated with such behavior. In most of the USA getting caught driving 160kph will earn you a stay in jail. Your high speed limits and even higher driving speed is why the vehicle death rate is so high.In town I get everywhere between 10 and 15l/100km , depending on traffic.
My record worst is maybe around 15-16l/100km.
I drive aggressive sometimes with pedal to the metal , but not all the time.
With my style of driving, I think driving in A will give more consumption every time, as I push the pedal more to have more response. Around here is not very healthy to overtake vehicles slowly and stay longer in the opposite lane.
I am not complaining. It is normal consumption.
I only use 100 octane fuel from Shell. 98 is not recommended in Europe. 95 is, but higher , the better for the engine .
There is nothing wrong with the car. If I want to get all of the A mode, I must drive with the trucks and busses and not overtaking them, which is very dangerous here.We have one of the highest death rates here, from auto crashes and accidents in the world. It is a war, man. If I have to monitor all the time the gas pedal and terrain, to use coasting I will be most possibly be involved sooner in accident , than driving little faster and concentrate on..... just the driving.
I don't have V6. It is Q4 280hp 2.0T engine, Veloce.
Highway speed here is 140km/h , but driving with 160km/h will not have serious consequences. ....Especially if you use Waze and radar detector. 😆
With 160-170km/h average consumption is about the same like in town - around 12 -13 l/100km. With 180- 190km/h - consumption around 14-15 l/100km. But I don't drive that fast,...usually.
Other roads, between the cities are mostly 90km/h , which means most people drive with 100-110km/h . With that speed and driving normal/not too aggressive, but not slow/ , consumption, around 10 l/100km. If not overtaking very often and using the coasting in N mode I can get about the same as with manual paddles n D mode - 8 l/100km.
Maybe if I drive with 80-90km/h, not more, not overtaking of any kind and using coasting when possible, without any load in the vehicle, without AC and using the wind in my direction , in A mode ,....I will get 7 l/100km consumption.
After all I prefer to be safer and drive as best as possible depending on traffic conditions, which includes often fast overtaking. That is why, more powerful engines and good handling cars can save you, not only the good brakes.
I am totally fine with consumption and really enjoy the car very, very much !!!
If I wanted boring, ugly and unresponsive, low consumption car, I should have bought some Toyota .
And yes, I ignore the speed limit when overtaking while driving in the opposing traffic lane. I agree that it is dangerous to do otherwise. Even then I can pass 4 or 5 cars without achieving 160kph and with the pedal to the metal the whole time. However when overtaking while driving on a multi-lane road, the only reason to accelerate to a high speed is that someone else is behaving in a dangerous fashion or the rules of the road are insane (Germany?).
