The 2006 Volvo S60 is a part of the first generation of the luxury sedan lineup. It is available in two trims, the 2.5T and the sportier R variant. Power comes from a choice of two engines – a 2.5-liter turbocharged inline-5 with 208 horsepower in the 2.5T trim, or a vigorous 2.5-liter turbocharged inline-5 with 300 horsepower in the R trim. Both trims drive the front wheels through a five-speed automatic transmission, with optional all-wheel drive. Safety features of the S60 include not just the expected front side airbags, but also full-length curtain-type airbags, anti-lock brakes, stability and traction control. The interior is highlighted by comfortable, supportive seats, and sophisticated options such as a Dolby Pro-Logic surround-sound audio system and a navigation system housed in the rearview mirror are available.
