40 years 6.9

The 450 SEL 6.9 played a special role in the long line of the most powerful models from Mercedes-Benz from 1975 onwards. What Daimler today as the S 600, Mercedes-Maybach (Lang Lang-Mercedes 🙂 and AMG S 65 are each presented separately, that was available 40 years ago as a special universal motor device 🙂 for road use - all in. The “six-ner”, as one of its designations is disrespectful for

scolded - as if they were ever with you with Gottlieb Daimler!

Anyway, one does not say "sixCOMMAneun". Officially: "SixPointsNew" (it's also called properly 240 D Three Point Zero or 300 SEL Six Point Three!). After all, one does not say "Emily" to the Rolls-Royce radiator figurine. Nobless oblige. And besides - where we are already there: who today one Mercedes G as "G-Class" designated, did not understand anything. It remains forever the "G-model"!

The Helmut Schmidt under the limousines

The 6.9: “He” was far more than a testosterone-charged S-class. Its upper-class base was the long version of the W 116. This S-Class still had bumpers. In the version W 116 as double guardrails (the StVZO forbade locomotive buffers even then 🙂 in the Chancellor Helmut Schmidt design. Under the paint of this special “special class” (Mercedes-speaking) everything was different.

6,9 liter large-bore engine - Picture: FactoryAbove the front axle, the 6.9 wore a heavy heritage, the Cast iron V8 of the Mercedes 600, the large piston engine of the state limousine presented in 1963: 6,3 liter V8 and 250 hp. After just 10 ticks of the fastest hand on the clock, the car was no problem at a speed of one hundred, double continuous speed. At the long pull man. The “short” 600 “managed” - we are in Swabia - 5 km / h more. With the two-and-a-half-tonne 600 you could saw a sports car at the traffic lights like “on the train”. Even a real saw like the Porsche 911 could leave the (short) 5,54 meter long one-room apartment standing. Udo Jürgens and Herbert Karajan drove such cars. The people drove Opel Caravans.

Race with Rolls-Royce

Rolls-Royce forced Daimler-Benz in the early 1970s to more displacement. Just had its V8 a pint (or as the short half liter in English means) has been refilled: 6,8 liter. So German-Daimler countered with 4 millimeters more bore and hollowed out the 6,3 liter to exactly 6.834 cubic centimeter inhalation volume. This was the result of multiplying 8 pots times 95 mm stroke with 107 mm bore. Almost 6,9 liters. Marketing just.

Mercedes 600 (W100) - Picture WikipediaWith this, Daimler won the new - after 1918 and this time peaceful - competition with the British for the most powerful cruiser. The large ships were still the Mercedes 600 Pullmann (6,24 meters) and the Rolls-Royce Phantom (at that time No. VI) - both also available armored, but unarmed. If the 600 was the flagship - aged and gorgeous - then the fast 6.9 was the Rear Admiral's choice of ship (but we're not trying to use classic naval tactics here).

With the 6.9, Mercedes wanted even more: power and speed. Less weight and less time to 100. Above all, the 6.9 did not suffer from severe performance losses like the 600: The “Big Mercedes” would have been able to do a lot more if its comfort hydraulics had not drawn off so much machine power. The 6.9 did not have this hydraulic system (too complicated, too maintenance-intensive, too expensive). Instead, he used conventional electric motors for windows, sunroofs, etc.

Long axle makes drive

As a result, the 6.9 offered tight 286 PS at relaxed 4.000 / min and longitudinal dynamics that can be described in numerical terms: When the machine operator demanded full force, 8,2 seconds passed standard 100. 234 units cruising speed were possible with an average 23,2 liters of bunker reserve requirement per 100 kilometer ride - these are the Measurements of "car, engine and sport”In 1975. Almost forgotten: The“ oil crisis ”at the beginning of the 1970s with its (ultimately only four) car-free Sundays almost thwarted the 6.9. So it came with a little delay. Initially, the price tag said 69.990 DM - how appropriate.

The driving values ​​of the 6.9, another 30 years ago, were only offered by the famous 300 SL. Its driver had to make a decision and employ a car mechanic: V / max or Acceleration. "Short"or Install “long” axle. The 6.9 could do both. It covered its eight seconds to one hundred and the range up to a speed of 234 with just three speed levels of the automatic converter. 549 Nm enabled a relaxed “long axis” with a 2.65: 1 ratio. For comparison: a current S 250 CDI / Bluetec,… vulgo diesel with 4-cylinder (OM 651) creates 500 Nm; But it “distributes” these over seven to (soon) nine speed levels. So much for the sporting potential of the six point nine.


The principle of hydropneumatic suspension. Picture WikipediaHardly any Mercedes driver from the 1970s would have swapped for a Citroën CX. It was the other way around. Surprise: What both of them had in common was the hydropneumatic chassis. The 6.9 was the only S-Class to have the same oil / gas-regulated bellows between the wheel and body - invented by the heirs of the inventor of the angular gearing: André Citroën. From 1975 onwards, the driver of the Top S-Class level compensation on both axles also benefited from the hydropneumatics padded for “La DS” in the 40s. It took XNUMX years before a floating S-Class was created again with the current S-Class!

Only the 6.9 could be hydraulically / pneumatically lifted by up to four centimeters. For example, when old mansions or hotels and their (bääh!) Underground garages were not yet set up for flat ramp angles for modern automobiles. OK, only the old 600er was more exclusive with its standard lashing eyes on the underside for air transport. A bit of Bugatti flair, one would say today if the Bugatti had that - but he does not have :-). Mr. Piëch: please have it retrofitted. Noblesse oblige. Incidentally, right-wing 6.9ers have NO leather, but the velor upholstery, which was then considered more noble. But you certainly knew that.

Quiz resolution

Thus, the 6.9 had unique selling propositions that were not available on other S-Classes for either money or good words. In addition to the large-piston engine, these were the hydropneumatics (with pull lever next to the light switch - priceless) and the speedometer up to 260 km / h. And if you see a W 116er with "6.9" sticker: He should then have the only standard on the 6.9 headlight wiper. The latter are also retrofitted only with massive effort, such as the series air conditioning. Rear headrests could be ordered for each S-Class. Series - you guessed it - only the 6.9, as well as the 215 tires: 6.9 exclusive. Anachronistic in the year 2015: The right mirror cost 1975 extra charge.

Late models shortly before the end of production in May 1980 had one of the first ABS systems. Some, including earlier models, already had a B-Netz car phone: 20.000 DM. Funny: If you didn't know where the car was, you had to try up to 19 (!) Area codes 🙂

The number code 540K-770-300SE-600-6.3-Rote Sau-6.9-500E-S600-S65 is the new quiz. The reader may like to write the resolution here in the comments.
