Vibrations in the steering wheel is not good. So far I've noticed two types of noises:
1. Direct injector clacking that is audible at all speeds. You can hear the injectors shut off when the engine revs down, especially noticeable when engine is rev matching in sport mode as you brake into a corner.
2. That gawd awful buzz that comes on at around 2k-2.5k RPM that others have said is due to turbos. I hope they find a solution to tighten this down.
Other than that, the car should be smooth and quiet, except for exhaust noise of course.
