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 (422 hp) and maximum torque of 540 Nm, this engine exclusively powers the SLK 55 AMG.
The world's most fuel-efficient V8 engine combines the lowest consumption figures with the superior power delivery and the typical sound experience which only a large-displacement eight-cylinder engine can provide.
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.
