Return of the ultimate limousine?

Watch out Rolls-Royce and Bentley, there’s a new uber limo wafting your way with a proud pedigree – the Mercedes-Maybach Pullman S 600.

Mercedes-Benz is marking the 50th birthday of the iconic Pullman saloon with a new version.

The second model to bear the Mercedes-Maybach name, it’s 6.5 metres of luxury and exclusivity.

The best-known Pullman of them all, the Mercedes 600 was launched in 1965 and the new car is a worthy successor.

As before, four passengers can sit facing each other in the compartment with an electrically-operated partition window.

The prices for unarmoured models start at around £370,000 and the first customers will take delivery of their vehicles at the beginning of 2016.

“Quite apart from providing stately and stylish seating for high-ranking passengers in the comfort and spaciousness for which it is famed, the new Mercedes-Maybach Pullman is of course the embodiment of exclusivity at its highest level,” said spokesman Ola Källenius.

Powered by a 6-litre V12 biturbo engine, the top-of-the-range Mercedes-Maybach Pullman S 600 is 1053mm longer than the recently announced Mercedes-Maybach S-Class.

The wheelbase is 4418mm, and at 1598mm in height, it’s more than 100mm higher than a Mercedes S-Class, for extra headroom.

The name Pullman was originally applied to railway carriages with luxurious open-plan compartments manufactured by the American Pullman Palace Car Company.

Pullman was soon also applied to the motor cars from Mercedes-Benz which were based on an extremely long wheelbase and offered a generously-sized passenger compartment.
