S-Class spruced up

Mercedes has used the mid-life update of its luxury sedan flagship, the S-Class, to debut a family of all-new six-cylinder engines, a more advanced suite of semi-autonomous tech and some minor styling tweaks. The return to straight-six propulsion includes both a 3.0-litre diesel donk in two power outputs and a 3.0- litre petrol, dubbed M256, that uses an electric compressor to help eliminate lag. Tech wise, the suite of driver-assist systems now integrates with the sat-nav and will alter braking, acceleration and steering for upcoming curves and junctions.
