regarding the bucket vs sport seats this is just choosing between stunning look, great body roll control and weight saving vs full electric, confortable but sporty as well and more weight.
Do you guys recall the weight saving between both seats ? Maybe 15kg less per seat ? More ? If you add buckets and ceramic you should be close to 50kg saved right ? or am I a bit too optimistic
Regarding the car overall feel (engine and chassis) I am shure I pretty much get how the ride will be/is knowing how the RS4 B7 is/was and te improvement made on the RS5.
The biggest surprise will indeed come from the chassis and all the electronic goodies eventhough overall weight is a bit too much... When it comes to the engine it will be pretty much RS4 B7 like IMO. The double clutch geabox will of course add some confort/speed but I expect the engine to be pretty much the same animal then B7 RS4. So no big surprise for RS4 B7 (past) owners.
