by Brian Byrne When the new-generation Mercedes-Benz S-Class is launched in October it will regain its former attribute of being both the largest and most expensive sedan in its segment.
This follows a period of restraint since the eight-year reign of the W140 version launched in 1990. The next car was significantly downsized in length and power following criticism.
The current S-Class is the best-selling luxury car in the world, but in Europe only holds the third rung of the ladder against BMW's 7 and Audi's A8.
