Background
The Mercedes W108/W109 series was launched in 1965 and remained in production for the next seven years.
An update of the much-loved W111 and W112 ‘Fintail’ saloons, almost 400,000 rolled off the production lines by the time it expired.
The W108 series was the one that first introduced the ‘S’ Class to the world and, in so doing, helped establish the marque as being the undisputed benchmark for engineering integrity, technical innovation and unrivalled build quality.
The W108 had a standard wheelbase, while the W109 had the longer version. The suspension was different too, with the short-wheelbase cars having conventional steel springs, while the long-wheelbase had self-levelling air suspension.
Offered with a range of engines from the 2.5-litre to the thumping 6.3-litre V8 with 247bhp and a top speed of 137mph, both manual and automatic gearbox options were offered.
First shown at Frankfurt in 1965, the 'S' Class Mercedes-Benz range was outwardly distinguishable from preceding models by a new, sleeker bodyshell with a lower roof and waistline and an increased glass area.
All models featured similar all-independent suspension as well as four-wheel disc brakes and power-assisted steering.
Although developed from the preceding 220 model's 2.2-litre unit, the new 2.5-litre engine of the 250S incorporated numerous improvements, including a seven-bearing crankshaft, and produced 130bhp at 5,400rpm, good enough for a top speed of 112mph.
