On our prescribed sighting-lap line, the Optima's chassis proved compliant while the standard high performance dampers (fundamental design shared with the Sorento's dual flow dampers) and suspension tuning found a good compromise between a relaxed ride and more aggressive roadholding. Off the driving line, the stock Nexen touring tires didn't enjoy steering corrections at speed, and predictably squealed in protest.
Pros: compliant chassis, relaxed ride
Cons: tires squealed in protest
