The 5.0-liter power unit M119 E50 became the first in the M119 family and is located in a row between the younger version of the E42 and the sports modifications of the E60 AMG and E63 AMG. In the new engine, a 90-degree aluminum bore was used, plus pistons from light alloys and forged connecting rods were used.
