Unfortunately, when the asphalt writhes and your right foot goes down hard, the Stinger does sometimes float like a butterfly-and not in a good way. We experienced several unnerving sideways twitches while traversing nasty heaves in the middle of fast corners that convinced us that firmer rear damper tuning was needed. Despite the car?s adjustable shocks and multiple driving modes, we couldn?t find a setting that endowed the Stinger?s chassis with the poise and feedback that cements the driver/car connection. What?s more, the throttle was too jumpy in Sport mode for smooth midcorner power applications, the transmission was slow to respond to calls for downshifts from the steering-wheel paddles, and the engine sounds merely ordinary in its upper rev range.
