Re: VW and Audi will split -BBC news report (turboglow)
Perhaps Passat suspension tuning will move even closer to Lincoln/Lexus/Buick. I doubt that major component sharing will change much, but spring rates, damping, tire choices, seat bolstering, glass thickness, amount of sound insulation, etc will probably move towards more comfort and silence.
If Passat handling remains at the present level (very probable) , the result should be pleasing.
