      AMG 5.5 Liter V8

      • The Ultimate in Performance with the Lowest Possible Fuel Consumption

        The newly developed AMG 5.5-Liter V8 engine featuring cylinder shut-off combines the ultimate in performance with the lowest possible fuel consumption. With a peak output of 310 kW (421 hp) and maximum torque of 540 Nm, this engine exclusively powers the SLK 55 AMG.

        The new M152 is based on the AMG M157 5.5-Liter V8 Biturbo Engine, which powers the E 63 AMG, CLS 63 AMG, S 63 AMG and CL 63 AMG. Numerous design features are identical, such as the displacement, bore/stroke, distance between cylinders, start/stop system and direct petrol injection technology. Distinguishing features versus the M157 include the new intake air ducting, new cylinder heads, the modified valve drive, an adapted oil supply system and an optimized crankcase.
