It's due in part to our tester's 18-inch performance tires and a sport suspension with Sport, Comfort, or Advanced Modes, but we were surprised at the S80's jarring ride, even in Comfort mode. It didn't really pay dividends with a tight, aggressive handling character either. Good, but a little vague in the corners and not very tossable what with all-wheel drive and stability control keeping things straight. Then there's Adaptive Cruise Control with Collision Avoidance (ACC): You drive down the road, and the car in front slows to a stop. As you brake, you get closer and the ACC makes a sudden, loud noise and flashes a red light. At the same time, it primes the brakes for maximum stopping power. Yikes.
