he M5 is, and always has been, the distillation of everything that makes BMW cars special. M division engineers, endowed with a streak of lunacy, take an already great BMW 5-series car and add power, improve its handling, and create a sedan that takes on dedicated sports cars. You get the feeling these guys share a kinship with those fun-loving, society-be-damned types who put a few special ingredients into a still and create moonshine. In this case, it's the new, 500-hp BMW M5, the moonshine of cars.
The differences between a regular-production 5-series BMW and the no-holds-barred M5 have never been greater. First and foremost is the new engine. In today's automotive world of economies of scale, mergers, and collaborations, it is rare for an automaker to design an engine that is entirely new, but the 90-degree, 5.0-liter V-10 is an engine that must have skipped kindergarten because it doesn't share any of its parts. The high-revving V-10 was made for the M5 exclusively, and it makes the car feel as special as anything built outside of Maranello.
