In base trim, the S80 has only adequate power, whereas the turbocharged T6 is downright stirring--quick by nearly any standard. Fuel economy is reasonably good, too. A base S80 averaged 19.2 mpg, while a T6 turned in a 20.7-mpg average. Shift action is smooth. Both versions offer sure-footed handling. Steering seems firm and precise, but some drivers might consider it numb or overassisted. Stable on the road, base sedans easily absorb bumps that register sharply in the stiffer-suspended T6. Best to try the T6 on a variety of surfaces, to make sure ride comfort is acceptable. Stopping power is strong, but a test base model suffered numb pedal feel. Doors open wide for easy entry/exit and the S80 provides generous room, front and rear. The dashboard layout is clean and modern, but the radio's station-memory function uses a dial instead of buttons and is a chore to preset. When activated, the optional navigation system's map screen rises from the middle of the upper dashboard. It's near eye level, and controls are on the steering wheel rather than on the dashboard. But like many such systems, this one demands study and patience to program and operate. In addition, the screen can be hard to see, especially in bright sunlight. Rearward visibility isn't the greatest, for a full-size automobile. In addition, the S80's large trunk is tempered by its small opening. On the plus side, the plush T6 Executive pampers its rear-seat occupants like a more costly Lexus LS 430.

Value for the Money
A serious contender among luxury-class sedans, the well-built S80 earns high marks for refinement, ergonomics, and trunk space. Volvo managed to pack a lot of safety and convenience features into its stylish, functional sedan. Fun to drive, the S80 is roomier than the rival BMW 5-Series, but handling and performance in the base 2.9 model are underwhelming. That tends to make the T6 a better value, despite its higher price.
