The number of S80 trims was cut in half for 2006 with the questionable discontinuation of the more exciting T6 trims. For this year the line was streamlined to two trims powered by the T5 engine, with All-Wheel Drive the difference between them.
This was the final year of this S80's generation before a total redesign for 2007. Still there were some changes, mostly concerning standard equipment and options. A new color, Willow Green, was also introduced.
Once again proving Volvo's commitment to safety, the 2006 S80 earned 5 stars in each NHTSA crash test: the Frontal Crash Test (driver front and passenger front), the Side Crash Test (front side and rear side), and the Rollover Test. User reviews praised the car's comfort, safety, and roominess.
