In 1954 the W180 220 series debuted. Nicknamed “Ponton” for its markedly round, slab-sided design, the 220 showcased an innovative single-joint swing axle for improved safety and comfort, an automated clutch, manually controlled fuel injection and even separate heaters for driver and passenger.
Five years later and the ‘Fintail’ Mercedes-Benz W111/112 arrived in five versions, from 220b to leading 300SE long-wheelbase form. The W111/112 took safety to a whole new level; boasting the world premiere of front and rear crumple zones, the first Mercedes-Benz car to feature disk brakes all-round, while an injury-reducing interior brought to the forefront three-point seat belts, a padded steering wheel and wedge-pin door locks.
In 1963 Mercedes-Benz unveiled the colossal W100 600 limousine, available in short-wheelbase and long-wheelbase ‘Pullman’ versions. Embellishments such as air suspension, hydraulic appointments all-round and a 247bhp 6.3-litre V8 shifting the hefty 2600kg body gave the 600 an air of supremacy, proving immensely popular with political figures and celebrities during its time. Production ceased in 1981 with 2677 examples built.
Two years after the debut of the 600, Mercedes-Benz launched the W108/109 saloons to replace the previous generation ‘fintail’ version. The W108 line, which included the 250S, 250SE, 280S, 280SE and 280SEL were larger than its fintail predecessor it replaced. The W109 was identical to the W108, but featured an extended wheelbase of 115mm and self-levelling air suspension. Its success as a “premium flagship” car convinced Daimler to add a long-wheelbase car to the model range and from that point on, all future S-class models would feature a long-wheelbase variant.
In 1966, company engineer Erich Waxenberger had a brainwave: extract the 247bhp 6.3-litre V8 unit from the 600 limousine and shoehorn the lump into the W109 body – thus creating the Mercedes-Benz 300SEL 6.3. The result was a nigh-on two-tonne saloon with enough performance that left Porsche 911S owners on an autobahn looking flat-footed. The 0-62mph sprint dispatched in an eye-popping 5.7 sec and onto a top speed of 143mph. Even Mercedes-Benz’s tuning subsidiary – AMG – got in on the act, producing a fettled 6.8-litre V8 420bhp version nicknamed the “Rote Sau" or Red Pig, which went on to finish 2nd at the Spa 24 Hours in 1971.
After years of subtly dropping the ‘S’ into its luxury flagship cars, in 1972 Mercedes-Benz eventually gave in, naming their W116 variant the S-class. Stamping its authority as the halo model in the German carmaker’s line-up, the W116 S-class was the first production car to get ABS – when it showcased the hugely advanced system in 1978. Other innovations included the first production saloon with a turbodiesel engine – the 300SD (launched that same year), cruise control and a collision-proof fuel tank.
In 1979, the W126 S-class was launched. Featuring improved aerodynamics and sleeker lines, the W126 continued the S-class technical trend, including such revolutions as the world premiere of the driver’s airbag in 1981 and front passenger airbag in 1985, passenger seat belt tensioners, a bodyshell with a ‘forked’ longitudinal member to meet the offset of crash requirements and lighter all-alloy V8 engines. The W126 S-class’s production run of 12 years was longer than any S-class before or since, with over 890,000 models sold worldwide.
Mercedes-Benz unleashed the bulkier W140 S-class in 1991 in the form of two wheelbase versions and a W140 coupé. In addition to boasting such electronic wizardry as Electronic Stability Programme (ESP) – another world first – adaptive damping, brake-assist and self-closing boot and doors, the W140 also featured double glazing on the side windows and was the first Mercedes-Benz passenger car to come with a production 12-cylinder engine. At the time, it was the brand’s most powerful passenger car - the 6.0-litre unit pumped out 408bhp.
