The M156 is the first V8 automobile engine designed autonomously by Mercedes-Benz subsidiary Mercedes-AMG, as previous AMG engines have always been based on original Mercedes engines. The engine was designed to be a naturally aspirated racing unit, and will also be used in a number of high-performance "AMG"-badged Mercedes-Benz models. 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 6.208 liters, it is marketed as the "6.3" to commemorate Mercedes' famed 6.3L M100 engine, its first production V8. The engine uses a bore and stroke. Output is at 6800 rpm with of torque at 5200 rpm. The engine, however, has been uprated to produce (and of torque) in the late 2007 S 63, E 63, SL 63, CLS 63 & CL 63 models(). Applications: * 2006 E 63 AMG * 2006 ML 63 AMG * 2006 R 63 AMG * 2006 S 63 AMG * 2006 CL 63 AMG * 2007 CLK 63 AMG * 2007 CLS 63 AMG * 2008 C 63 AMG * 2008 SL 63 AMG ==M156 lawsuit== In 2011, a class action lawsuit was filed in United States District Court in New Jersey against Daimler AG, Mercedes-Benz, Mercedes-AMG for alleged defects in the M156 engine contained in AMG vehicles built in 2007-2011 model years leading to premature wear. The plaintiff claimed the combination of cast nodular iron camshafts and 9310 grade steel valve lifters contributed to the premature wear, but the defendants had known about the defect since 2007.〔(Class action lawsuit to be filed against Mercedes alleges AMG V8 defects )〕 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mercedes-Benz M156 engine」の詳細全文を読む スポンサード リンク
