The S60 R is fitted with Volvo’s most powerful five-cylinder engine. Volvo’s
2.5-liter in-line turbocharged power plant produces 300 horsepower and 295 ft-lb
of torque between 1,950 and 5,250 rpm. Power output per liter of cylinder
displacement places it among market leaders for performance efficiency. The
engine reaches maximum torque at 1,950 rpm, thanks to a larger cylinder bore and
a turbo from KKK, with a maximum charging pressure of about 1 bar. The high
charging pressure significantly raises the temperature of the intake air, so the
S60 R is fitted with twin intercoolers. The engine is equipped with Dual Wide
Range CVVT continuously variable valve timing, on both the intake and exhaust
camshafts. CVVT adjusts the valve opening times to suit the engine speed and
load, lowering fuel consumption and reducing emissions, while increasing
performance. The emission standards of the R engine satisfy American LEV
requirements. To withstand the increased stress, pistons and connecting rods are
heavily reinforced and cylinder head cooling is enhanced. The oil sump is
designed to safeguard oil supply to the engine under extreme G-forces.
Performance by Volvo also means the safety of handling and control that comes
from the unique Volvo Four C (Continuously Control Chassis Concept). With this
active chassis system, which compensates for road variances using a
sophisticated network of sensors, All-Wheel Drive with Instant Traction, DSTC
(Dynamic Stability and Traction Control), and “performance on demand”
versatility, the S60R retains its status as Volvo’s state-of-the-art flagship
sport sedan.
