Handling is responsive with quick, solid turn-in. The chassis, thanks to the wide track and rigid body construction, is wonderfully flat and steady when pushed through smooth curves. The P225/60R16 Goodyear Eagle tires squeal under aggressive cornering, but the GTP handles rapid changes of direction with confident, road-hugging equanimity.
The suspension dampens quick little chatter-inducing bumps well, although it clearly announces its softness when the twisties get uneven. But that's a reasonable compromise for the comfortable ride, which is firm but not harsh, with very little vibration transmitted through the seat of your pants. The four-wheel independent suspension uses MacPherson struts and anti-roll bars (30 mm front, 18 mm rear); the suspension tuning allows a significant amount of jounce at the corners, which you feel in your shoulders. Sometimes it feels as if the suspension wants to keep on working, after the bumps are crossed. But overall, the Grand Prix is well sprung.
The Grand Prix's strong brakes are one of its best features, with a very solid pedal feel. The 11-inch four-wheel discs are vented in front, and don't get hot when being overused down steep hills. The brakes inspire confidence when slowing dramatically from high speeds, and the ABS is noisy but dead true under panic stops from 65 mph. Next Page
