With so much buzz surrounding the new Mercedes-Benz S-class flagship, we take a look back at the history of its pioneering luxury saloon
16 November 2013

Mercedes-Benz has one aim when it comes to its range-topping S-class – to make the best car in the world.

That’s no mean feat, but as the automotive industry has witnessed time and again over the years, with each new Mercedes S-class variant comes innovative technology never before seen on a car. The S-class has always been a game-changer. So where did it all begin?

History of the Mercedes S-class

The Mercedes S-class DNA can be traced back to 1951, when at that year’s Frankfurt motor show the German car maker introduced the svelte W187 220 and the W186 300 models. Available in saloon, coupé and cabriolet styles, the 220 was powered by a 2.2-litre six-cylinder overhead cam unit producing 80bhp. 

In grander 300 guise, an 113bhp 3.0-litre inline-six propelled the car onto a top speed of 100mph – cementing the 300 as the fastest German production car at that time. Technical highlights included a safety door lock to prevent doors from bursting open and electronically operated torsion bar suspension to compensate the height of the rear wheels under heavy loads.

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.

Fast-forward seven years and the W220 replaced the now-ageing W140 with a completely new design, resulting in a body that was slightly shorter and lighter than its predecessor. The W220 continued the S-class’s pursuit towards ever-improving safety with eight airbags, ‘Pre-safe’ occupant protection system and an automatic childseat recognition system. Automatic cylinder shut-off, ventilated seats and a ‘Keyless-Go’ access system also debuted. Mercedes-Benz also launched the first official AMG-badged S-class in the form of the S55 AMG – armed with a 493bhp supercharged 5.4-litre V8.

In 2005, the W221 S-class was unveiled at that year’s Frankfurt motor show, with evidence of a bulking diet - proportions being slightly larger all-round than the preceding W220. Technological bragging rights included lots of ‘assisting’, with infrared Night View Assist, Blind Spot Assist, Park Assist, Lane-Keeping Assist and a proximity control including an automatic braking system.

With Mercedes-Benz’s new W222 model pioneering rear seatbelt airbags and tweaks to its Airmatic Active Body Control and Distronic Plus systems, can the S-class continue to be the technological tour de force not only in the luxury saloon car segment, but in the automotive world?

Best one in the whole range.

Bullet-proof engineering and technical excellence maybe, but you could never accuse the S-class of elegance. To these eyes the latest model is the pick of the bunch in that respect and the first one I've actually liked the look of (the preceding 20 years' efforts were particularly ungainly), although being of a certain vintage I have a soft spot for the 108 - love those old interiors, and the all-round visibility is something we can only dream of nowadays,

Wide cars in a world of narrow.

[quote=Herald] but you could never accuse the S-class of elegance. To these eyes the latest model is the pick of the bunch[/quote] Hardly any Mercedes could ever be regarded as elegant - the pagoda roof SL and the exceptionally neat 190E of the 1980s being the notable exceptions. I'd also list the W126 and W220 S Classes as being pretty good too. All modern Mercedes are ill-proportioned with strangely truncated rear ends and far too many fussy swage lines going in all directions down the sides.

Was the W126 the last of the old-school 'bank vault' S-Class Mercs? Probably not, its successor - the W140 - would win that accolade. Nevertheless, looking at pictures of the W126 now it's not hard to see where Lexus drew inspiration for their LS400 model from - separated at birth.

I remember when the W126 was launched and the press were drooling over every word Mercedes said about it. Final sentence in one influential mag was from a Merc exec saying 'if you think the W126 is good ,wait until the next generation model!'. When the W140 arrived it was a big disappointment and it took them sometime to get back on track.

Since the W180 the Mercedes S Class has been the epitomy of the German Wirtschaftswunder ( = economic miracle ). But there is no getting away from the fact that these cars lack the timeless elegance and beauty of the Jaguar XJ.

The first application of ABS in a production car was the 1966 Jensen FF. In 1971 the Chrysler Imperial and Nissan President got 4 wheel ABS, and Lincoln, Cadillac and Oldsmobile got rear wheel ABS. The first luxury hybrid was the 2006 Lexus LS600H, four years before the S400. Airmatic and Active Body Control are two completely different suspension systems. ABC uses coil springs.
