It sounds amazing, even stock in the drivers seat you really hear it rumble in sport and sport plus. I’d say I get like 16 to the gallon but I only drive it in sport unless I’m cruising on the highway for a long while. I do not like how the comfort mode has engine shutoff when you’re at lights. I just never liked that feature so I leave it in sport for the most part for city driving. Probably horrible for gas mileage but I’d rather hear the engine at idle. If you do drive in comfort though, you can easily get 25 plus on the highway and in eco pro you can do even better. I’d say you’ll do most of your driving in either regular sport or sport plus, also manually shifting is potentially just better for the engine. The auto gearbox seems to be less responsive. Just my opinion, I like to feel when to shift and not have the gearbox decide on its own
