When in auto mode, the setting that impacts gas mileage the most is the drive mode (D1, D2, D3) and of course how fast you drive and accelerate. In sequential mode, it's all about how you drive.
Am I wrong?

Are you sure it’s literally just the gas pedal sensitivity? At least in older M cars, my understanding was that the actual fuel mapping (and other things) changed with a press of the sport button. I may be wrong.
My G80 is a manual. And I can tell you that changing the engine mode in my car, even just on the highway cruising, changes the rate of fuel consumption. And it appears to do so materially. I also found this in my 2020 M2C. |
That's my understanding. Per the owner's manual:
"The M Engine Dynamics Control affects the response of the vehicle to accelerator pedal movement."
In highway cruising, what would be the purpose of changing the rate of fuel consumption, as you say? You're cruising, why on earth wouldn't you want the best fuel economy possible?
My F80 was the same. What older M cars are you referring to?
