Volvo's S80 is luxurious, roomy and safe. Its styling is representative of the new direction Volvo has taken away from the boxy designs of the past. Silky-smooth power is available from a pair of highly evolved six-cylinder engines, along with a choice of sophisticated stability and traction control systems. Ride quality is emphasized over handling to reduce road vibration. The twin-turbocharged engine on the T6 is much more powerful than the standard 2.9. Volvo's interior ergonomics are excellent with handsome switchgear and comfortable leather seats.
