The 2010 S80 provides what many Volvo buyers are looking for: safety. With exceptional safety scores, the S80 is a secure choice in the class. Optional safety features when the S80 was new provide additional peace of mind. These include adaptive cruise control, as well as lane-departure, collision and driver fatigue warning systems. With up to 18/27 mpg city/highway, the Volvo S80 earns good fuel economy for the class and also has a good reliability rating. However, top rivals have even higher reliability ratings.
