M156

The M156 displaces and shares very little with other Mercedes-Benz engine families like the M155. The bore spacing, block design, and other features are unique to the AMG engine. Although this engine displaces 6.2 litres, it is marketed as the "6.3" to commemorate Mercedes' famed 6.3 L M100 engine, its first production V8. The engine uses a bore and

M156 lawsuit

s contributed to the premature wear, but the defendants had known about the defect since 2007. The lawsuit lasted approximately 14-months. In November, 2012, litigation came to a halt when the New Jersey District Court dismissed the plaintiffs’ first amended complaint for lack of standing. The plaintiffs were given the opportunity to further amend their complaint to show that they had standing to sue, but plaintiffs made no further filings with the Court. On January 7, 2013, the Court signed an order closing the case.
