The S 65 AMG is powered by the Mercedes-Benz M275 V12 engine rated at and of torque. It includes restyled front and rear bumpers and rocker panels, larger wheels, brakes, and tires, four exhaust pipes, modified and reprogrammed suspension for sport biased handling, and various interior changes. Apart from the higher output engine, many of the AMG modifications give the S 65 AMG a distinctly different character than the S 600 base V12 model. The S65 continues to use the 5 speed transmission, because it can handle the higher torque of the engine, as opposed to the 7-speed transmission.
