S-Class W126 AMS Test - 40 year celebration of Mercedes 500SEL W126


The Mercedes-Benz W126 is a series of passenger cars made by Daimler-Benz AG. It was marketed as the second generation of the Mercedes-Benz S-Class, and manufactured in sedan/saloon (1979–1991) as well as coupé (1981–1990) models, succeeding the company's W116 range. Mercedes-Benz introduced the 2-door C126 coupé model, marketed as the SEC, in September 1981. This generation was the first S-Class to have separate chassis codes for standard and long wheelbases (W126 and V126) and for coupé (C126).

Unfortunately I wish I had the scan copy of this test to post, but had to just get this from the AMS website, but it is very interesting and great modern road test of a 1982 Mercedes 500SEL W126, to celebrate the 40year anniversary launch of the W126 in 1979 IAA.

MERCEDES 500 SEL (W 126) IN THE TEST
Still the best car in the world after 40 years?

How time flies when you move the best circles! Just like the most successful of all Mercedes S-Classes, the W 126, whose launch is now 40 years ago. Back then, we chose the 500 SEL in the test as the best car in the world. Let's see if the S is still in a class of its own.

As the star spreads to the horizon and the first rays of the sun turn the dim gray of the sky to red, we are already on our way for a few of the quiet little hours of the early day. Long enough to find peace, as it only arises with the security, which gives the certainty to arrive safely and unconditionally. And that only makes it possible to dare to ask big questions: Should everything have been better in the past, how terrific does it have to be the best of the past? There is only one way to find that out. And that leads to Lahr. In M Mercedes 500 SEL W 126th

Although it does not require the tradition of the "old in the test", there is, in addition to this reason, even a reason that the S class class W 126 occurs here. It celebrated its premiere in 1979 at the IAA, so in a good early, which is actually already 40 years ago. In 1980, in the first test of the W 126, we judged him in critical sobriety as "the best car in the world". Well, we did not have it smaller then.

But rarely was a car ahead of its time as the Mercedes 500 SEL W 126th For the there was off the start of the W 116 introduced ABS, from 1981 driver airbag and front passenger belt tensioners. Yes, at that time, it was the safest car ever, with a body and crash structure that even outweighs the newly emerging danger of offset crashes - with 40 to 50 percent overlap. The technicians optimized the aerodynamics up to the run of the gutter and sunk windscreen wiper to cW = 0.36, reduced the weight compared to the old S by up to 300 kilograms, the style of body and interior.

At that time, it was the safest car in the world, with a body and crash structure that even outweighs the newly emerging danger of offset crashes - with 40 to 50 percent overlap.

The 126 remained in production for twelve years, only a facelift in September 1985 interrupted the steady running of the assembly line in Sindelfingen. With 818,036 copies, it is still not only the most successful model of the S, but the luxury class at all. Therefore, we wanted to plan the anniversary test early. So call bravely at Mercedes-Benz Classic and just do not let it surprise you:

"Hal ..."
"Seb, you again?"
"Um, so I ..."
"You just had the G-model for the 'old man in the test'."
"Yes, but ..."
"Already clear: now the 126er."
"Could we ..."
"I thought so. We have three choices: an early 500 SEL, a medium 300 SE and a late 560 SEL. Which, when? "
" Um, pfff ... 500 SEL? Autumn? "
" You can get it. See you."

S is all gold that shines
So we get the lapis-metallic Mercedes 500 SEL on a summer's Monday, which got lost in an autumn week. It is a 1982er, which cost at that time in basic version 63.845 Mark. All special equipment is listed in the data card - a long, rather continuous series of numbers, ranging from 410 (electric sunroof, DM 1,316.45) to 877 (reading lights in the rear, DM 113). Strangely enough, it does not include the headrests in the rear (that would have been the 430 to 186.45 DM - just with such rousing detail knowledge you bring back buoyancy in frustrating small talk at Christmas parties). In any case, the Mercedes 500 SEL with extras cost 86,625.80 DM - a high, yet reasonable price for a car, which is on the way for 37 years at the top.

The SEL skims through the pylons during the slalom with good lateral inclination and high security.

The SEL 500 costs $ 86,625.80 - a high, yet reasonable price for a car that has been at the top for 37 years.

After 1981, the Mercedes 600 outnumbered, the Mercedes 500 SEL is the elite model, parked in front of Chancellery and Villa Hammerschmidt - the S-Class of President Richard von Weizsäcker with the most casual number plate of the Republic: 0-1. Since you are quite jealous over there in the chancellor bungalow, where you with the extras "front seat reinforced right" (35.03 DM) and "additional longitudinal adjustment front seat right" (107.35 DM) permissibility so rather not keep up.

Alright, the exit Lahr. We just had half way to go. How fast the future becomes a thing of the past when you think about it in the past. Turn, refuel, wash, then over to the airfield, directly to the box and right on the scales. It shows 1,721 kilos for the 5,135-millimeter-long SEL - that's how much an E 200 weighs today.

We wire the electronics. But before we go out, we take the inside dimensions. Since there is a lot to measure inside, finally, the Mercedes 500 SEL extends by 14 inches in the wheelbase to 3.07 meters. Therefore, not only the rear doors are the same length longer, but also the handles in the rear, which gives them prospects for a second career as a shower towel holder.

Mercedes-500-SEL-W126-Interieur-169Inline-1fd0ff73-1650941.webp


On the crumpled back seat, the seat extends to a spacious 83 centimeters.

The driver is also undisturbed, but accommodated in a functional atmosphere. Everything clear and catchy on the big steering wheel. Ignition, selector lever through the zigzagging on D, foot from the brake pedal, the Mercedes 500 SEL rolls on. The V8 humming just above its reduced idle speed of 500 / min. It counts as the increased compression, the power reduction from 240 to 231 hp and the longer rear axle ratio to the measures of the "Mercedes-Benz Energy Concept 1981", which demands the top ten thousand to increase efficiency not just unbearable cuts in performance, speed or comfort.

Because of its lower weight, the five-liter even surpasses the vehemence of the nominally higher 450 SEL 6.9. Even now, as we have gently recorded noise levels, the Mercedes 500 SEL proves the power from the depth of the cubic capacity. At a staggering 405 Newton meters, the four-speed automatic, which is not overstated anyway, normally starts the second gear to start, only to L it starts the first one. So what, what the traction reserves calls for, followed by an acceleration ropes, which could once batter the self-image of sports cars. At the start, the starting torque stabilization supports the rear axle against submersion, then the SEL pounces, reaching 100 km / h in 8.5 seconds, 160 km / h in 20.7. More than the values impressed the casualness in which the Mercedes 500 SEL accelerates.

Mercedes-500-SEL-W126-Exterieur-169Inline-18ae1a-1650933.webp


Sovereign succeeds the Mercedes 500 SEL W 126 also the brakes, he delays the many tempo neatly away.

On the other hand, driving dynamics tests are more demanding - especially for a car that is used to setting a clear course. Thus, the Mercedes 500 SEL curves around the pylons in the slalom with stately side slope and high security. Nevertheless, he still knows to avoid indecent hectic with his rückkeldungskeuschen steering. It's so indirectly translated that you simply can not do it at a faster pace with cranking.

Anyone who expects the handling of the handling to be more dynamic thanks to the optional hydropneumatic suspension can wait for this as well as a real improvement in suspension comfort. Because surprisingly awkward the oil-air suspension responds to short bumps. Long waves swinging away better, but never supersede the impression that one would have better invested the 3,310.90 DM at that time. Outweighed in gold, it would have since been 4,873 euros.

This could already finance part of the expenses for fuel. Because now, after we've packed up and back at the gas station, garnish significant amounts of premium gasoline in the tank. But you can not afford stinginess when it comes to driving a Mercedes 500 SEL.

Above all summits there is peace'
So it starts, a piece only on the highway. Then as always overland. Today with wide open sunroof. Oh, the Oppenauer Steige is currently closed. Well, then we climb the Black Forest just over the highway. The roads do not have much of an incline to counteract the impact of the engine. The tops of the fir trees are strobing over the deep glossy paint of the bonnet, when it rises gently only after bends. Now, the automatic makes the V8 turn higher and more demanding, without ever exploiting its reserves ever significant.

After a short time and virtually incidentally, the Mercedes 500 SEL reaches the summit of the mountain. He never left that power. The good of the past, that's getting better and better.

ADVANTAGES AND DISADVANTAGES
body
  • Very representative and statutorächtiger appearance, which requires no oversized dimensions
  • Extensive space for rear passengers
  • Even drivers travel in a reasonable amount of space
  • Excellent all-round view
  • Furnishing style dispenses with elegance, which could disappear with changing fashions
driving comfort
  • Even at high speed, noisy background noise
  • Almost perfect hydropneumatics
  • Formula 1 champions Lauda, Rosberg and Piquet drove W 126 for comfort
drive
  • Highly cultivated V8, as vehement as once the 6.9
  • Automatics determined to absolute sovereignty
driving characteristics
  • Also through tear-proof steering extremely safe to drive
  • Late oversteer tendency - a drift comes already casual in the presidential parade
  • Lateral inclination symbolically stands for agility / dynamism
  • Tight traction illustrates the power potential of the drive
safety
  • ABS, driver airbag and front passenger belt tensioner optional
  • Armored version? Like, and the bill as always directly to the Chancellery?
environment
  • Were probably despite V8 unloaded, kept all cars like the Mercedes 500 SEL 500,000 kilometers and four decades
costs
  • Are enough for everyone

CONCLUSION
We only have five stars. Two are there for the power to remain undisputed performers, even though others have more horsepower, two for never being fashionable, but over decades modern, one for the V8.

The next AMS issue they will road test the 1986 AMG Hammer 6.0 W126 coupe. I hope that @DeDe or @Laurent T can post the scan of this.
 
Sorry for bumping an old topic @Rolf but I found this road test from Road & Track from March of 1985, which is from an issue of the magazine that's for sale on the Ebay. Not sure if the link is going to work as the forum appears to not direct to links are not within the forum. Anyway, here it is the link just so the seller doesn't get angry with me. Sorry!:sorry:

It's a toss up between the W126 and W124 as to which was the greatest sedan ever built. The design was so pure and lean. What an era it was.

The 300E W124 was the sweet spot of the Mercedes range in the 1980s. The 300E performed better than the 500 SEL and 420 SEL W126, while also having better fuel economy and a cheaper price tag. Thanks to a lower trunk sill, the W124 had better trunk access compared to the W126 with its high trunk sill. In conclusion, I personally think the W124 was likely a better car than the W126, but to each their own.

I thought back in 1992 that the 400E was the most complete car I'd ever driven. Surprisingly enough I felt the same way about the later model 300SE, a SWB I6 model. More agile and playful than the 560SEL, if not as fast. They all were just epic cars.

Right? When we weren’t burdened with immense power and performance.

fun fact. 1985 was closer to 2003 than 2024 is to 2003. Why 2003 you ask? That’s when we saw the E55 and SL55 with 468 and 493 hp and as they say the rest is history

The US spec Mercs in the 80s were so underpowered cause of emissions restrictions. The power output of this test 500SEC was 184HP which is the same power output as the 280 models in Europe (they produced 185PS/182HP), while the 500SEC in Europe produced 231PS/228HP and accelerated from 0-100km/h (62mph) in 8.1sec (so did about 7.8sec to 60mph), much faster than the 9sec of this test car.

I didnt like the front lights of the US spec Mercs in the 70s and 80s they were separated units for the main beams and low beams and not under one glass panel like the Mercs available in other countries worldwide.

Yep, we didn’t get the more powerful engines and better styling until the facelift for 1986.

The 300SE was the Goldilocks W126 imo. It featered a modern I6 cylinder 188 ps and 260Nm torque, had an acceptable fuel economy and it’s drive was rather agile ( for a W126). If I was buying one, I’d take it in stead of one of the V8.

I always went between it and the 420SEL. They were such a joy to drive.

Another fun fact, I learnt how to drive on a 1986 E300.. speaking of does anyone know the power figures? I thought it had 216hp, but maybe not
I recall the 3.2 i6 after 1995 pumped out a maximum of 228hp. That had the 4 valve per cylinder I believe. So 216 sounds like a lot on the 86. I think the 380 se v8 was around 200hp.
 
Another fun fact, I learnt how to drive on a 1986 E300.. speaking of does anyone know the power figures? I thought it had 216hp, but maybe not
The Euro spec 300E had 140kw/190PS initially at launch in 1985 then power was decreased to 138kw/188PS and with the catalytic convertor it was further reduced to 132kw/180PS. The 300E-24 followed in 1988 with a 24valve version of the 3.0 inline 6, that delivered 170kw/231PS without a cat converter (or 162kw/220PS with cat convertor). The 320E replaced both 300E models in 1993 and that used a slightly detuned version of the 3.2 24valve inline 6 from the 300SE W140 delivering the same 162kw/220PS as the 300E-24 with cat convertor as standard but had more torque of 310nm vs 270nm. The name changed to E320 in 1993 also for the change to E-class and big face lift for the W124.

The first 300E from 1985/86 was a benchmark car at the time and made the mid-sized Mercedes a sports saloon for the first time with performance to closely match the much more powerful E28 BMW M535i.
 
Both excellent choices.
PS I liked the SWB W126 better than the LWB. In those days MB catered the SWB fans with the top engine. Alas, they don’t do that anymore nowadays.
1717316209384.jpeg
The last time the US saw an SWB was the W220 S350. Sold new for about $64K about 19 years ago. You can’t even get a new S for twice that money now. Talk about inflation!

The 300SE W126 model is probably one of the best models. It made a sizable leap on the previous 280SE in performance despite only having 2kw more power (138kw vs 136kw).

Auto Motor und Sport tested the Catalytic Convertor Version (132kw/180PS) in 1985 and its acceleration and top speed were very close to the 380SE (150kw/204PS) from 1982.

I think the 560SE must be a very rare model as most other markets including South Africa only got the 560SEL model,
