My 2022 3.3T SP should arrive next week, and I plan to drive it in sport mode all the time, like it's always the case on all my vehicles. The reason is not to drive like a maniac, but because I don't want to lug the engine. In other modes, modern cars run at almost idle, and I feel bad lugging the engine that. I don't think turbo engines are any different than NA ones, but maybe due to their lower compression, they're less prone to lugging? But on the other hand, they run with much higher pressure, due to the turbos. At any rate, I understand sport mode drinks more fuel even sedately driven (like I do most of the time), but you don't lug the engine for sure, and car responds quickly when needed, which is the main reason to use sport mode. It feels lethargic in other modes. At any rate 14 mph sounds really bad, but if you're aggressive with the throttle a little, it's probably normal. But I've read on many reviews that Genesis is at the bottom of the efficiency pile compared to its European competition, so I'm not getting high expectations for great gas mileage. Ha ha. I'm bummed that our 3.3T engine doesn't have dual injection, like the 3.5, which is newer, and more efficient. But it has been proven, so hopefully less likely to have issues. We'll see
