M 157: New high-performance engine from AMG

Mercedes-AMG’s all-new high-performance engine M 157 is presented to the press in Affalterbach. The 5.5-litre V8 has a maximum output of 420 kW / 571 hp, peak torque of 900 Nm and features several technological highlights, including biturbo and direct petrol injection with spray-guided combustion. Together with the M 157, AMG also presents an S 63 AMG show car, which is equipped with the new biturbo V8. Visually this is reminiscent of the spectacular 300 SEL 6.8 AMG racing touring car, which in 1971 was affectionately dubbed the "rote Sau” ("red pig”).
