THE S60 uses a power-assisted rack and pinion steering system. The steering wheel adjusts steplessly, both vertically and horizontally. The turning circle diameter ranges from 10.8m to 11.8m, depending on tyres. Likewise, turns lock-to-lock range from 2.8 to 3.0 depending on the standard wheel and tyre combination. Volvo claims the power steering rack was tuned to provide good steering feel while reducing unwanted kickback while driving over rough road surfaces common to Australia.
