2014 Mercedes-Benz S65 AMG showcased at the LA Motor Show 2013

The Mercedes-Benz S65 AMG debuted at the LA Motor Show, and powered by an AMG 6.0-litre Biturbo V12 engine, it is the German automaker's most powerful sedan yet.

The vehicle has staggering power figures of 630PS and 1000Nm of stomach-churning torque, mated to a 7-speed AMG SPEEDSHIFT PLUS transmission that has three selectable modes, namely Controlled Efficiency (C), Sport (S) and Manual (M). With an electronically limited top-speed of 250kmph, the car goes from naught to 100kmph in 4.3 seconds. Efficiency and emission numbers stand at 8.4kmpl and 279g/km respectively. A start/stop system, reduced-friction bearings, transmission oil heat management, aluminium crankcase, alternator management, Lithium-ion battery, forged crankshaft, carbonfibre engine cover and multispark ignition are other mechanical highlights.

It also gets Mercedes 'Magic Body Control'. As the 'Road Surface Scan' detects undulations with the help of the stereo camera, Magic Body Control adjusts the suspension in advance to suit the situation. At the same time, AMG-specific tweaks on the 4-link front and multi-link independent rear offer more feedback. The car also has an electromechanical AMG speed-sensitive sports steering with variable ratio, AMG forged lightweight alloys and AMG high-performance braking system.
