2015 Mercedes-Benz S 600 has debuted in Detroit and it showed what it hides under its hood: the V12 biturbo engine. The top model in the S-Class range will be offered with long wheelbase and with a luxurious package of equipment.

At the Show was also announced that not only the S 600 but al models in the current range will be upgraded with the addition of a head-up display, touchpad and Collision Prevention Assist Plus.

Precisely, the V12 engine has an output of 530 hp (390 kW), and the displacement of the engine has increased from 5,513 to 5,980 cc. The maximum torque is 830 Nm (613 lb-ft) and is available from 1,900 rpm. Mercedes-Benz S 600 will also feature for the first time the ECO start/stop function as standard. The combined fuel consumption of the car is estimated at 25.4 mpg.

What have to be highlighted are the features of the engine: all-aluminium crankcase, one-piece chain drive, forged crankshaft in high-grade quenched and tempered steel, modified forged pistons, new engine control unit, new dedicated ignition coil with twin-spark ignition, cam follower, two intake and one outlet valves (three-valve technology), hollow-stem outlet valves, filled with sodium, low-temperature cooling-water circulation with separate expansion reservoir.

As a standard the S 600 will be equipped with variety of technologies such as the LED Intelligent Light System, the Magic Body Control suspension with Road Surface Scan and the Driving Assistance package Plus. The latter comprises Active Lane Keeping Assist, Active Blind Spot Assist, BAS PLUS with Cross-Traffic Assist, Distronic Plus with Steer Control and Stop&Go Pilot, Pre-Safe Brake and Pre-Safe Plus.

To go further into details, all of the functions of the head unit will be controlled by fingertip gesture, thanks to the optional touchpad. The latter offers an additional, full-function input option over and above the existing COMAND Controller and LINGUATRONIC.

The head-up display displays important information directly in the driver's field of view on the front windscreen. It provides important data on speed, speed limits and navigation instructions.

Collision Prevention Assist Plus also comes as a standard here. Next to the Brake Assist system, which helps to protect against collisions at speeds of over 4 mph, this system adds another function: if the danger of collision persists and the driver fails to respond, the system is able to carry out autonomous braking at speeds of up to 124 mph, thereby reducing the severity of collisions with slower or stopping vehicles.

2015 Mercedes-Benz S 600 will be available on the market in March.
