The MAN SD202 is the direct successor of the SD200. 468 buses were delivered to the Berlin transport authority (BVG) between 1982 and 1992. Based on the operation experience with the three prototypes built in 1982 and 1983, the first batch of 70 production buses was introduced in 1986.
On technical terms, these buses are very similar to the predecessor SD85 which already used the same drivetrain components. Due to the modified exhaust, the sound of the 150kW S2566UH engine is much more bass-like.
The 70 buses of the D87 stock were put into service in 1987. They differ only in minor details from the previous stock. The most noticeable differences are the black MAN lettering, the round shaped wheel cases, and the smaller engine hood.
From this series on, these buses have much bulkier window rubbing linings.
The 65 buses of the D88 stock are the first SD202 to be suitable for wheelchair access, shown by the blue icon on the front. To achieve this, the former buggy stand was enlarged at the cost of two seats. Furthermore, the grab pole in the middle of the rear door was removed.
The interior grab handles are now painted red and the MAN sign at the front has its dots. The D88 also featured electrically operated doors and an improved gearbox control reducing fuel consumption by a very early up-shift.
The 68 buses of the D89 stock differ only in minor details from the preceding series. The upper deck heating is now fitted underneath the rear bench resulting in a slight forward shift of this now.
The alignment of the side grill has changed for the same reason. At the driver's seat, the blinker and wiper levers are now combined in one multifunctional lever on the left.
The 71 D90 buses delivered in 1991 were the first to use an electronically controlled "intelligent" door mechanism offering smooth closing of the doors and even a sorting of the overlapping door rubber strips.
The edge of the aisle and the pedestals are now lined with yellow strips in contrast to the black ones on previous series. The buses no. 3807-3846 have been fitted with infrared sensors above the front door to control traffic lights ahead - a system that has been tested on route 92 in the early 90s.
The largest batch of SD202 with a total of 81 vehicles entered service in 1991. These new buses were fitted with halogen spots in the front area of the lower deck and with a larger strop indicator light on the dashboard. New vehicle licensing rules also demanded a rear fog light.
From the beginning, these buses were prepared for a later installation of interior destination displays, thus the mountings on the ceiling. The actual displays were fitted later in the 90s.
To offer a larger swing range for the driver's back rest, the divider between the driver's seat and the front staircase has been fitted with a tray extending to the rear.
The 40 buses of D92 stcck are the last SD202 ever produced. These buses were already factory fitted with ABS and traction control. For better passenger information, the D92 features interior displays controlled by an advanced IBIS-2 board computer.
There is a new window alignment in the upper deck with an additional sliding window for cleaning purposes and an even hub cover on the rear axle and the halogen spotlights in the lwer deck. The driver's panel also features new funtions, such as the so-called 20h-switch and the simplified gear selectors.
