2004 Mercedes-Benz E55 AMG isn’t fast. In fact it’s the most powerful E- Class sedan that Mercedes has ever built! In the E55, AMG’s 5.4-liter Kompressor V8 engine roars out 469 horsepower and 516 pound-feet of torque. Torque which is available at only 2,650 rpm. In addition to the 13.1-pounds of boost from the screw-type supercharger and intercooler, everything from cylinder heads to crankcase has been reinforced or reshaped to produce maximum thrust. Thrust which thunders to the rear wheels through a 5-speed multi-mode automatic using AMG’s SPEEDSHIFT software.
