W111 The symbol identifies a family of luxury cars produced by German automaker Mercedes-Benz between 1959 and 1971. The versions with 3-liter engine are identified by the initials W112. The Mercedes-Benz W111 and W112 owe their nickname (Heckflosse) the characteristics small rear side fins.
History and Profile
The history of the W111 range begins in 1956 when the then technical director Fritz Nallinger begins to present the project for the replacement of 220 Ponton. Upon several aspects, Nallinger gave carte blanche to the people, but was adamant about three things: the new car had to ensure safety for the occupants had to be spacious and should not be launched later in the fall of 1959.
Mercedes-Benz, in designing the most exclusive W112 and W111, he stuck to modern (for the time) the principles of passive safety: the cell density formed by a solid cage reinforced with steel tubes, large parts of the body deformation planned and collapsible steering column. In addition, the same coat of arms of the House position on the radiator was deformed and sold in case of impact. This was the first Mercedes-Benz to take these design criteria. The idea was conceived and materialized by the engineer Hungarian Béla Barényi.
Spectacular crash tests: a car, driven by a small rocket engine, was thrown against a concrete barrier at a speed of 50 km / h. To test the resistance to rollover, however, the car was launched (always by the same rocket engine) at a speed of 80 km / h along a runway slope gradually increasing.
The meccnica was largely taken from the W180 series, starting from 2.2 liters to manifold (M180) and injection (M127), which was slightly revised to improve delivery. Even the mechanical chassis was from W180. The most changed was the rear deck with a central articulation, which in the case of W111 'saw the addition of a central clearing Mollon. As the front, however, the pattern was almost identical and diferir only for the auxiliary frame, to simplest form.
The refinement of the steering ball, contrasted with a little '4-drum brakes, while the availability of automatic transmission 3-speed, as an alternative to manual 4, gave prestige to the model.
Everything was then covered with an elegant American-style body, characterized by Charming rear fins that earned him the nickname Heckflosse (in German means "rear fins). The vertical headlamps to the front made it impressive.
The first prototypes were tested in January 1958 and in February the following year, one of the earliest examples is conducted from Stuttgart to Naples and back to test the reliability of the car as a whole.
Debut commercial production
The W111 was launched officially in August 1959: At the time of onset, the range includes versions 220B (with engine 95cv), the 220Sb (with diesel 110cv) and 220SEb (with injection engine from 120hp). The three models were going to replace, respectively, 219 W105, the 220S and 220SE, all three belonging to the W180 family (the 219 bore the initials of the project W105, but it was strictly a project resulting from W180). The sedan was part of the smallest 190 and opulent Ponton 300 Adenauer. This is actually one of the forerunners of today's Mercedes-Benz S-Class
Everything inside the W111 was voted the best comfort possible time. This was a heating system in which they were made independent of the area right and left side of the passenger, a kind of very first dual-zone configuration. Furthermore, the large cockpit was also made luminous by the large glass surfaces also contributes to optimum visibility at various angles. In 1961, enriched the range of coupe and cabriolet versions of 220Sb and 220SEb. Another new feature of that period was the W110, the basic version equipped with the 1.9 M121, and in fact was, however, to replace the 190 W121.
That same year, with the imminent departure from the scene of the dated 300 Adenauer, was presented with the W112, in the variants, and 300 SEL 300 SE. Both versions were moved from the sophisticated (but fragile) 3-liter DOHC aluminum M189 injection 160 bhp.
Since 1962 the engine of the 300 SE was also mounted on the W111 coupe and convertible (with automatic transmission and disc brakes). That same year, the basic versions, with a 2.2 liter engine, may have to request the automatic transmission and the year after receiving the standard front disc brakes.
In 1965 there was a revolution in the range: sedans 220SE, 300 SE 300 SEL were replaced by the corresponding versions of the new W108/W109. Versions 220B and 220S were instead replaced by 230S W111 and W110 model 230, equipped with the new 2.3 M180 VI and VIII. In 1968, all W111 sedans were finally lifted production, while the coupes and convertibles continued their existence until 1971, as updated with the new engines of W108 and W109 sedans.

Mercedes-Benz W112
But the official versions of garden W111 are made between 1966 and 1967 by the Belgian IMA, based in Mechelen. These versions were known as Universal and to build upon the 230S W111, as well as the various versions of the W110 series. The production lasted very little, because in a short time the body Belgian closed its doors.
Other body-builders across Europe will be challenged in the creation of the garden, commercial versions, ambulances and hearses vehicles derived from the W111 and W110. They relate to the Austrian Jauernig, the Swiss and the Portuguese Movauto Marbach.

Launched in April 1961, the W112, better known as 300SE and 300SEL if a longer wheelbase of 10 cm, is the flagship version of the sedan Heckflosse. Created to provide a replacement to the 300d, now near the exit of production, 300SE/SEL inherits the 3-liter M189 injection 160 bhp, that this new model, however, is made entirely of light alloy. The 300SE and SEL propose innovations at the level of suspension, provided with independent wheels, but not using traditional coil springs, but of the innovative pneumatic cushions, whose pressure is controlled by a compressor. A unlteriore device automatically adjusts the ride height of the car.
The braking system has four disks and Dunlop servoassisitito and dual circuit brake system.
The 300SE and 300SEL were originally envisaged only with automatic transmission, but the pressing demand by customers, convinced the top Daimler-Benz to offer the possibility of having the traditional manual transmission, available starting in 1963.
In 1965 the 300SE and SEL are removed after production complex have been produced in 6748 copies.
In 1965 were launched the 250 SE coupe and cabriolet (W111 III), moved from 6 cylinder M129 2.5-liter Capable of 150CV. These versions mounted disc brakes even on the back and were then replaced in 1967 by 280 SE (coupe and cabriolet), equipped by 2.8 M130 injection, capable of delivering up to 160 hp. In 1969, the 300 versions (coupe and cabriolet) gave way to the 280 SE 3.5 (always coupe and cabriolet), driven by the new M116 engine, a V8 3498cc from 200cv, matched only automatic transmissions. In July 1971 the coupe W111 and W112 were replaced by Mercedes-Benz SLC. Regarding a convertible, there would never be a direct heir. The only ones that could give even the pleasure of an open car big engine would be the tip of the versions of SL R107.

Universal and other versions
Esisitite are also special variants of bodywork on a W111. The best known is the one with wagon body. This variant does fall in the official programs of the German House, but were never produced in factories Mercedes-Benz, but by outside contractors. In 1964 the coach builder Jacques Coun realizes some family-based 220B, 220Sb and 220SE.The braking system has four disks and Dunlop servoassisitito and dual circuit brake system.

Mercedes-Benz W111 Coupe and Cabriolet
In February 1962, introduces a 300SE coupe and cabriolet (W112 / 3), which fits the same 3-liter M189 of 300SE and SEL. With a maximum power of 160 hp, these cars were capable of reaching the 180 km / h despite their mass, equal to 1600 and 1700 kg respectively for coupe and cabriolet. In 1964, the 300SE W112 / 3 see their power rise to 170 hp.The W111 coupe built on the platform were presented to the press in February 1961, while the presentation to the general public took place at the Geneva Motor Show of that year. A few months later at the Frankfurt Motor Show, were also presented cabriolet W111.

Compared to the sedan from which it derived, the W111 coupes and convertibles were lower and broad. The impression was to be confronted with more cars planted on the ground, which gave the idea of owning an impressive road holding. Without doubt, the look was more sporty and aggressive than the more austere sedan and limousine. Major was also the overall mass, which was increased an average of one hundred kilograms.
The interior was more luxurious than those of the sedan and also included the floor carpeted. The upholstery leather and could be required in each case was combined with door panels coordinated. The place was more sporty driving, as you could see from the same gear lever, the wheel moved to the floor for a more exciting.
Technically, there were initially uneventfully, except for the braking system, which in these models was of mixed type, with discs front and drums on the rear axle. Motor sport there is the same 2.2-liter injection of 220SEb. For the record, there have been no coupe or cabriolet W111 and W112 Feed carbs: they have been by injection.
