I have the F-sport and the ride is fine, if anything, its the tyres that add a degree of firmness, and that can be changed with better tyres, as I have always found bridgestones to be firmer than most.
Performance is more than adequate for me, its not a car for petrol heads because it wasn’t designed for them, as Michael said, so I don’t know what they expect from it, its for economy really, and it does it in a calm, sophisticated and refined way, and better than a diesel, thats for sure.
