The twin-turbocharged V12 engine develops 516bhp and a massive 612lb ft of torque from just 1900rpm.
It goes on sale in spring in long wheelbase form as standard and will be fitted with Mercedes' full panoply of new technology including Magic Body Control (which is controlled by sensors which scan the surface of the road ahead and sending information to the suspension control system) as well as the all driver support technology including pedestrian recognition.
US market models get a Nappa leather interior, Night View Assist, Executive Rear Seat package (individual airline style seats) and rear seat entertainment. Up front, the big control screen can be controlled via a fingertip, smartphone style.
The S600 will not be the ultimate S-Class model, however. The company is said to be planning a longer, even more luxurious model which will be sold under the 'Pullman' badge. This model effectively replaces the Maybach brand and is expected to be popular in the Middle and Far East.
