Mercedes-Benz S-Class Pullman with stretched wheelbase. The interior of the S-Class Pullman doubles as a mobile office. A wheelbase stretched by 1 m (3.28 ft), slightly raised waistline at center and rear, and changes to the roofline distinguish the S-Class Pullman.

The additional space is dedicated to the rear passenger area. There are two rear-seat units with 700 mm (27.6 in) leg room between them, which is 200 mm (7.9 in) greater than in the Pullman based on the previous S-Class. The standard seat row has electrically adjustable outer seat positions but two electrically adjustable individual seats are available as an option. A powered glass partition is fitted between the front and rear areas of the interior. Power-operated fabric curtains are fitted to the rear windows. The options list is long and includes an intercom system between rear passengers and driver, a bar with refrigerated compartment, multimedia consoles with two monitors, DVD player, TV receiver, work tables, telephone and fax, and additional lighting.

Compared to the standard car, the Pullman has a slightly raised waistline at the center and rear, and a redesigned roofline. The bodyshell is reinforced and side panels designed as hatches provide access to various systems. A redesigned, three-piece propshaft is fitted, and the suspension is "reinforced." Maximum gross vehicle weight is 2800 kg (6160 lb)—about 400 kg (880 lb) more than the long-wheelbase Mercedes-Benz S500. The Pullman is an integrated design, not a retrofit, and is now in limited series production in DaimlerChrysler's custom shop at Sindelfingen, Germany.

The name Pullman harks back to the middle of the 19th century and American industrialist George Mortimer Pullman of Chicago, who built luxury railway cars. Mercedes has been producing Pullman variants of its cars for more than 70 years, defining the concept in 1928 as a "large, comfortable touring and VIP car with a partition between the driver's seat and passenger compartment."
