Does the car coast down slowly from speed or does it seem like there's drag from the brakes or driveline?

I do live in a hilly area but I mostly drive normal, sometimes ill gas it. I'd say my commute is 50% city 50% highway. When I fill my gas tank it says something around 220 mile range on a full tank. As far as the car goes it drives normal, very stiff but I assume thats normal. And I drove a f30 328i before this car and that car coasted and maintained speed with my foot off the gas but with the 128i there seems to be more drag, not sure if thats normal? I also use 91 octane bc thats whats available here in Cali
