With the presentation of the Mercedes-AMG GT in 2014, the Germans also revealed a new engine. The 4.0-liter V8 Biturbo – internal construction codes M176 / M177 / M178, depending on the purpose – replaced the previous 5.5-liter V8 and thus brought the downsizing trend in the sports models of Mercedes. Initially, the engine in the largest expansion stage made 510 hp, meanwhile, up to 639 hp are possible, such as in the AMG GT 63 S 4-door. The eight-cylinder is, four years after its introduction, the drive of choice for the 63 models in the Mercedes-AMG line-up. In detuned form, the unit even powers models which are not branded Mercedes-AMG. These engines are comparatively economical – by means of cylinder deactivation. #m177 #V8engine #amg #oldbenz
