Okay, I'll eat my words!! This was true a few years ago with the previous GTS. However most of the Portugal press-launch cars seem to have 21" wheels. However these do of course all have air suspension. As I keep saying, it's imperative to specify air suspension with 21" wheels.
I note the following from the AutoCar review. Not clear whether this is down to the larger wheels or the lowered suspension as implied. I suspect it's the larger wheels:
I suspect this wouldn't be an issue with 20" wheels.AutoCar wrote: If there’s a criticism it’s that the ride isn’t as cosseting as you’d expect. Sport and Sport+ deliver absolute body control, but mid-corner bumps can have the car hopping and skipping a little. Normal gives a little more compliance, the GTS breathing more easily with the surface, but there’s some lumpiness at low speeds as the shorter travel suspension struggles with sharper and more ragged imperfections.
