However, the capacity has grown from 5.5 to 6.0-litres, and power climbs from 510bhp to 523bhp as a result. A huge 830Nm of torque is developed from just 1,900rpm.

The S600 can complete the 0-62mph sprint in just 4.6 seconds, and hits a limited top speed of 155mph.

The new engine features stop-start, which helps improve fuel economy from a claimed 20.0mpg to 25.4mpg. The CO2 emissions also drop from 329g/km to 259g/km.

What equipment do you get on this flagship Mercedes S-Class?

As it’s the flagship model the S600 includes a host of hi-tech standard kit. The list includes Mercedes’ full LED headlights and Magic Body Control dampers that scan the surface of the road ahead of the car and adjust the suspension to suit. Mercedes’ Driving Assistance Package Plus is also thrown in.

This comprises a whole host of electronic driver safety aids, including Active Lane Keeping Assist, Active Blind Spot Assist, Brake Assist with Cross-Traffic Assist and adaptive cruise control that can also steer the car.

The S600 arrives in the UK in May. Prices haven’t yet been set, but it will cost more than the S63 AMG, which starts at £119,565.

Mercedes has also confirmed that, from March, all S-Class models will get the option of a smartphone-style touchpad for inputting information and controlling the infotainment system.

A head-up display will also be on the options list, while Collision Prevention Assist Plus technology will replace Collision Prevention Assist.

In addition to automatically boosting brake response at speeds of over 5mph, the car can also carry out autonomous braking at speeds of up to 124mph. Electric windscreen heating will also be added to the S-Class options list.
