The Volvo S60 combines excellent performance and a great shape with outstanding safety features. It feels like a tight European sedan and does a good job of smoothing out rough roads. The S60 fills the middle range in Volvo’s lineup: It’s larger than the S40, but not quite as large as the premium-luxury S80. Its interior is handsome and the available leather has a high-quality look and feel. Notable improvements for ’06 include a revised all-wheel-drive system for better performance, newly designed wheels and simplification of the options and packages.
