More details of Maserati's new flagship Quattroporte luxury saloon have been released. The latest generation of a model first unveiled back in 1963 is the fifth to carry the Quattroporte name. The 400 bhp, 4.2-litre, 32-valve V8 is positioned behind the front axle and connected to a rear-mounted transaxle gearbox in unit with the differential for ideal weight distribution.
