Mercedes W108 Service Repair Manuals

The Mercedes-Benz W108 and W109 series vehicles were luxury cars produced by Mercedes-Benz from 1965 through to 1972 and 1973 in North America only. The W108 compared to the W111 but had a lower body waist line that increased the window area. The cars had a lower ride, by 60mm, and wider doors +15mm. The result was a visibly more sleek appearance and an open and spacious interior. Jump to Manuals

The W108 suspension system featured a reinforced rear axle with hydropneumatic compensating springs. It sat on larger wheels (14”) and had disc brakes on the front and rear. The W108 vehicles carried over many of the basic engineering principles from previous models, but had many refinements to make them some of the most well equipped cars of the era. The 300SEb was especially well-appointed, featuring burled walnut dashboards, automatic transmission and power windows.

Mercedes Benz W108 Production Specs Sheet

The W108 series was premièred at the Frankfurt Auto Show in 1965. The initial model lineup consisted of three W108s: 250S, 250SE, and 300SE.

The 250S was the entry-level vehicle fitted with a 2496 cm³ Straight-six M108 engine, with two dual downdraft carburetors, delivering 130 bhp (97 kW) at 5400 rpm which accelerated the car to 100 km/h (62 mph) in 13 seconds (14 on automatic transmission) and gave a top speed of 182 km/h (177 on auto).

The 250SE featured an identical straight-six, but with a six-plunger fuel injection (designated M129) with performance improved to 150 bhp (112 kW) at 5500 rpm, which decreased 0-100 acceleration by one second and increased top speed by 11 km/h (7 mph) for both manual and automatic versions.

Approximately 130,000 of the less powerful 250 S/SE models were built during the first two years of the W108 existence.

The 300SE came with the M189 2996 cm³ engine. It had a modern six-plunger pump that adjusted automatically to accelerator pedal pressure, engine speed, atmospheric pressure, and cooling water temperature, to deliver the proper mixture depending on driving conditions.

In November 1967 the W108 added production for the 280S and 280SE. These replaced the 250S, 250SE and 300SE, however production of export-designated 250S would continue until March 1969. In January 1968, the model line was joined by yet another car, the 280SEL. The car had the longer wheelbase of the W109, but lacked the pneumatic suspension and other features of the 300SEL. Hence the chassis code remained W108.

During summer of 1970, the M116 was added to the W108 lineup on both regular and LWB, the 280SE 3.5 and the 280SEL 3.5 respectively.

Arrival of the big-block 4520 cc 225 hp (168 kW) M117 engine allowed for a final set of W108 vehicles to be launched in the spring of 1971: the W108 280SE 4.5 and 280SEL 4.5. The 280SE 3.5 and 280SEL W108s were then retired as production ended in the summer of 1972.
