OFFICIAL PRESS RELEASE
Stuttgart, May 28, 2010



Peak of perfection in automobile manufacture
Widely held view: “The best car in the world”
Bedded in the extraordinary tradition of the brand’s luxury-class vehicles

The 140 series S-Class Saloons gave a clear message when they were introduced in 1991: their size and design lent them an imposing appearance, combined with highest comfort and lavish interior spaciousness. Certainly these attributes are appropriate to a Mercedes-Benz S-Class. And yet this model series was anything but undisputed when it came out: critics complained it had turned out too big, which brought disadvantages in everyday use, and on top of that was out of step with the times. Such opinions were voiced mainly in Europe. In the USA or in Asia, for example, many customers took exactly the opposite view. For them, the 140 series was an S-Class in exactly the right format – precisely because of its impressive appearance, which to them was simply befitting of a vehicle in which the world’s successful, wealthy and political leaders could either drive themselves or be driven. This divergence of opinions was to accompany the saloons of the 140 model series from that point on, and the successor series launched in 1998, the 220, turned out rather more discreet. Nevertheless, the 140 series received a great deal of praise from all sides. In 1991, for example, the trade magazine Auto, Motor und Sport, Germany, went as far as to write: “It would not be wrong here to describe this as the world’s finest car – any less would be to do Mercedes an injustice.”

The world’s finest car – that is quite a claim. But it is one Mercedes-Benz and its predecessor brands have been living up to since the beginnings of the automobile. For the 140 series the engineers and designers addressed the task with the greatest dedication. Leaving aside the sheer dimensions of the body, one has to give great credit to the stylists under the supervision of chief designer Bruno Sacco: what they drafted was a luxury-class saloon with clear lines that unmistakably established its connection with brand history, yet at the same time delivered a statement for the 1990s and were almost timeless in character. Almost twenty years on, a 140 series S-Class is still an extremely handsome car.

The high standard applied to the vehicle was reflected in all details. For instance, the interior, so lavishly appointed, simultaneously demonstrated the restraint desired by the majority of S-Class customers. Spaciousness and features made the time spent in a 140 series S-Class an absolute enjoyment. That was also true of the driver’s seating position: perfectly equipped, it made even extremely long journeys exceedingly pleasurable.

The suspension also played a part in this. The engineers used all their resourcefulness and skill to design it: not only was travel in the saloon extremely safe on any road surface, it was also extremely comfortably. In addition to excellent springing, the body was decoupled from audible and otherwise perceptible vibrations. And although the 140 series S-Class was a big car, customers and motor journalists all over the world nevertheless praised it for its road manners – it was fleet-footed and able to negotiate even winding country roads impeccably at speed.

Typical of the great effort invested by Mercedes-Benz in this vehicle, for example, was the double insulated glazing, which benefited safety and comfort in several ways: avoidance of fogging (condensation) and icing, enhanced thermal insulation, enhanced insulation against external sources of noise, better flow of air around the vehicle and prevention of wind noises caused by window seals. Never before had car windows been so meticulously designed.

The high safety standard already attained in the previous series was clearly raised further by numerous measures. For example, the body structure of the 140 series afforded still more protection in all types of accidents. A number of details – solutions designed to take the sharpness out of potential points of contact – served the protection of other road users as well. The braking system was state-of-the-art, delivering optimum deceleration values. From 1995 onwards the Electronic Stability Program ESP® was additionally available, initially for the eight-cylinder S-Class model and later for all models with automatic transmission. In the S 600 it was standard equipment. After December 1996 all models additionally featured the Brake Assist BAS, which optimally increased braking power under emergency braking and shortened the stopping distance.

As was customary in the S-Class, six- and eight-cylinder engines were available to power the car – from 1991 on there was even a twelve-cylinder power plant. This unit epitomised the art of engine making, but the other units too enabled a mobility ideally suited to the Mercedes-Benz S-Class. All were fitted as standard with an emission control system featuring a closed-loop catalytic converter, and consequently satisfied comprehensive environmental standards.

At the same time these engines were symbols of the longevity of the 140 series – they, and, of course, the entire vehicle, were designed for very high mileages and thus for years and years of use. That made the 140 series S-Class well suited for use as a modern classic: anyone who buys one today, acquires a vehicle built to meet the highest requirements. In that sense it is part of the remarkable tradition of the luxury-class saloons of the Mercedes-Benz brand, which together with its predecessor brands goes back to the beginnings of the automobile.

Mercedes-Benz’s excellent spare parts supply has helped maintain a modern classic: almost every part can be procured through a Mercedes-Benz dealer and the company’s own ordering system; delivery is usually made overnight. Some authorised service shops have even been designated Classic Partners, possessing outstanding competence in handling older vehicles. And particularly where young classics are concerned, all Mercedes-Benz company-owned sales and service outlets and partners boast the same high levels of expertise as ever. Not for nothing does the slogan “Service for a lifetime” apply to all vehicles of the brand.

At the time it was by far the best car in the world it was ahead off any car on the road..We still have a 1992 300SEL with 395000km running although the car has been abused motor and gearbox are still perfect only issue was the brakes and electrics but electrics were due to the rats eating the cables at my cousins house...

When i have the car washed properly and look at it it still amzes me at how great a car it was when it was launched also it has a great pressence which i think has lacked on the S Class since then i Know thw W221 is a favorite off mine and has good pressence.The W140 was just immense it was like a tanker my dad still says its his favorite car he says the comfort in that car and the look or pressence is unbelievable..

I hope with the W222 Mercedes can take the S class way ahead like the W140 did to the rest off the industry...:usa7uh:
 
I still can't stand the rear of "ze Tank", surely one of the ugliest MB rears ever. The W126 and W220 are so much better design-wise, they have that classic elegance in their design for which Mercedes is known for.
 
The W140 will never be one of M-B's better designs. It reeks of its era a bit too much, and indeed lacks that grace of classic Benzes. It was part of the 90's M-B era, which is legendary in itself, but kind of took a break from many of M-B's classic and historical design points.

Also, it is the car that Bruno Sacco himself states he was never too happy with.

However, just last night, I was thinking of how bad@ss my older brothers old S500 W140 was, black with chrome 20" Lorinzers, lol. That thing was so EXECUTIVE/MAFIA feeling when you rode in it. Silent but deadly in a way. Felt like granite.

I found these interesting design mock ups of the W140 from the web today.

1) On this mock up check the heavily framed windscreen with unusual flush chrome trim. The side glass has similar design to production version but interesting the front lights have a W202 C-class look to them.

2) This mockup looks much smaller than production version and front lights also have a W202 C-class look to them.

3) This mock up and number 4) rear lights have a W201 190 look to them and I think look better than the production version lights.

5) This mockup has a heavily black tinted green house with blacked out A and C pillars.

6) Even Mercedes were toying with the thought of a W140 T-model.

7) This mock up looks almost production ready

8) Interesting design with similar front end to production version but with enclosed rear wheels:

9) This rear end has styling tones of the W126 but I reckon would have made a better look for the production version than the actual version that came out.

10) This mock up profile view is much sleeker and lower than production version. Possibly the kind of car Bruno Sacco would have preferred to bring out.

11) Similar to the above mock up but even more lower boot and bonnet line with slimmer lights.

12) This for me is one of the best looking mock ups, it was sleek, hightech and highly aerodynamic with its enclosed rear wheels. Would have made a great production car but maybe was too advanced for the time.

13) Another sleek mock up but not as well designed as number 12) in my opinion.

Rolf, thank you! Very nice look behind the scenes of this (almost forgotten) ancestor of the S-Class. There are rumors that in Western Europe there are more W126 than W140 registered as most of the latter ended up being exported into emerging countries, while the former kept a steady fan community!
 
In the late 1980's when developing the W140, Mercedes Benz already had plans to bring out a 6.0ltr 48valve V12 engine in the S-Class as an answer to the 5.0ltr 24valve V12 in the E32 750i/L.

This is snap shot of the first V12's on the test bench in 1988. At that time the V12 was producing about 355PS (261kW) which is considerably less than the production versions 408PS (300kW) when it came out in 1991.

Rumoured BMW V16 engine been tested in an E32 BMW:

But at the same time Mercedes had a V16 on the drawing board as rumours (and later shown) of prototypes of a BMW E32 fitted with a 6.7ltr V16 were circulating in the motoring world. The BMW engine was basically meant as an answer to the Mercedes V12, it was the 5.0ltr V12 with additional 4 cylinders added that produced 6651cm3, power of 414PS (304kW) and 625nm of torque, capable of 0-100km/h in approx. 6.0sec and a delimited top speed of 175mph (282km/h). The BMW engine was so large for its engine bay that the radiators had to be fitted in the boot, so the car effectively had no luggage capacity.

The Mercedes V16 would be the same concept as that of BMW by adding 4 cylinders onto the M120 6.0ltr V12 to produce an engine with 8.0ltr capacity. This would have been used for a super W140 S-class badged 800SE/SEL. Mercedes only built 3 to 5 prototype engines compared to 15 been rumored to be built by BMW. The 8.0ltr V16 would have produced a massive 540PS (397kW), which would have been nearly 100kW more than the 6.0ltr V12 in the W140 600SEL and even more power than the current 6.0ltr Bi-Turbo V12 with 530PS (390kW) in the 2015 W222 S600!!!

But unfortunately for both BMW and Mercedes their V16 engines never made it into production possibly due to the huge size and massive cost.

Interesting, this type of off set frontal crash test into a solid T bar object was only introduced recently by IIHS
 
What?? Where are the Youtube videos? I had planned to watch the rest of them, but now they disappeared shortly after you linked them here. There's numerous W140 artifacts I've come across over the years (some above already), but I never knew this thread existed. Thanks to those that have provided.
 
:mad:I really can't believe those videos are gone for good. Quite stupid that someone instantly removed them on Youtube for no reason. I would never do that to my viewers of course, if no copyright infringement threats were being made.:rolleyes:(n) Would be nice to get a response DJRaze99, as to what happened.
 
Wow that is almost 20years ago already, amazing how time has flown past. Certainly brings back memories, that AAV looked great much better than the production M-Class which came out in 1997. That first generation M-Class wasn't my favourite Mercedes SUV, the 2nd gen model is fantastic much better than the first one.
 
Hahaha, nice!

That IAA pic is awesome too. It's not that long ago, but it looks like a retro Bond movie almost :D
Particularly interesting how much space there is and how few people there are.
