Is there any difference between EFFICIENCY MODE AND DYNAMIC MODE on fuel CONSUMPTION?

[@bridoboy143]

I have a a6 c7 sline cvt and after using efficiency I can definitely feel the car is slower with the reves and when in cruise control it takes a very long time to build up speed also in efficiency I have noticed a big difference in diesel on long drives saves me a lot of money on re fueling I was getting around 25 to 30 mpg now I get around 40 ish not so great but an improvement

The real difference between efficiency and dynamic (in terms of fuel consumption) is when you accelerate and decelerate

Feel weaker when in eco modo

I have the 35 TFSI S-Tronic Mild Hybrid and the difference is huge on my 2021 A3 Sedan! Depending on the roads and my driving Efficiency averages 3.7-5.4L/100KM while Dynamic averages 5.5-7.0L/100KM It's mostly noticeable when driving in heavy traffic or slow mountain roads, in efficiency my engine uses 2 instead of 4 cylinders during 50% of my accelerations then regenerates the battery, shuts down the engine and just rolls forwards, when I accelerate gently only the electric smoothly pushes forward without even engaging the clutch. When in dynamic all 4 cylinders are always on, the clutch is always engaged and the engine only shuts down when stopped, electric is drained instantly for a noticeable acceleration boost. On the TDI models the difference is barely noticeable if at all. Also when driving at constant speeds like highways with ACC there's no difference at all between different drive modes.

Newer car, mine was a 2012 A7 v6 3.0TFSI. There was absolutely no change for me

IC engines are simple, during idling the engine needs a rich mixture and a while accelerating phase and full throttle operations the same (rich mixture), but however while cursing the engines are the most efficient as they need a lean mixture. Targeting to drive a car by cruising at particular speed (with gear in overdrive, but that’s handled by the gear box), will always yield you maximum efficiency. Different modes are provided in the car in terms of engine response. While in eco mode, the ECU sends fuel to the engine in a manner that it accelerates to the desired speed but by drinking minimal fuel, therefore making it less response, dynamic on the other hand always aims to keep the engine more lively, or more responsive (mostly at turbo region

Apparently you are not in efficiency mode, even when you have clicked efficiency mode! I haven’t coded mine yet but I have managed to get it to efficiency mode by driving very smoothly at about 65mph, when that happens the bar at your dash indicating fuel economy becomes green! Yours isn’t green which shows that cylinder deactivation hasn’t happened!

Well, always been like this. Maybe this function is jot available in my country

Did you have sport mode engaged?

Joder el mío es un A4 b8 177 , 2.0Tdi año 2013 , tiene 3 modos , confort , dynamic, e efficient, lo llevo en confort , hago percusrsos pequeños, que opinas ??? , gracias por tu atención,saludos de España

You takking bollocks here . How can you compare 2 different modes on motorway on cruise control . Okg
