First introduced in 2003, Volvo's S60 R boasted Haldex AWD mated to a 300 PS (221 kW; 296 hp) / 400 N·m (300 ft·lbf) inline-5. The 2004–2005 models came with a 6-speed manual transmission, or an available 5-speed automatic which allowed only 258 lb·ft (350 N·m) torque in 1st and 2nd gears. The 2006–2007 models came with a 6-speed manual or 6-speed automatic transmission. The new 6-speed automatic transmission allowed the full torque of 295 lb·ft (400 N·m) in all gears. Other aspects which set the R apart from standard S60s were the large Brembo front and rear four-piston brakes, standard 18" 5 spoke "Pegasus" wheels with 17" as a no cost option, blue faced "R" gauges, standard HID headlights, as well as the Four-C suspension system. Four-C (a short name for "Continuously Controlled Chassis Concept") allows the user to select from three modes: Comfort, Sport, and Advanced. "Comfort" attempts to soften the car over bumps, while "Advanced" firms the suspension considerably and gives more aggressive throttle response - a setting Volvo implies is for use on the race track. This is accomplished through a drive by wire throttle, allowing the same pedal travel to result in different performance when the appropriate mode is selected,[9] electronically-controlled shock absorbers that can adjust themselves 500 times a second, and a complex series of sensors throughout the body of the vehicle. Volvo collaborated with high-tech system developer Ohlins Racing AB and shock absorber manufacturer Monroe for the self-adjusting shock absorbers.[10] The S60 R continued the tradition of "R" cars for Volvo beginning in 1995 with the introduction of the 850 T-5 R. Top Gear reviewed the car in episode 9[11] of series 2. They panned the overly complicated and intrusive traction control system, and it set a slow lap time of 1:35.0. But they also found it to be very comfortable and civilized, and especially recommended the estate version. Jeremy Clarkson noted "More like a miniature version of the Rolls-Royce Phantom than a serious competitor to the BMW M3."
