Heckflosse (pronounced hek-flos or hek-floss-ah (German))
A nickname for the Mercedes-Benz W111 & W112 sedans produced between 1959 and 1968 (1961-1971 for the coupés and cabriolets with the abbreviated fin) and usually translated in English as “fintail”.
1959: A compound word in modern German, Heck (rear; back) + Flosse (fin). As a surname, Heck (most common in southern Germany and the Rhineland) came from the Middle High German hecke or hegge (hedge), the origin probably as a topographic name for someone who lived near a hedge. The link with hedges as a means of dividing properties led in the Middle Low German to heck meaning “wooden fencing” under the influence of the Old Saxon hekki, from the Proto-West Germanic hakkju. In nautical slang heck came to refer to the “back of a ship” because the position of the helmsman in the stern was enclosed by such a fence and from here it evolved in modern German generally to refer to "back or rear". Flosse is obscure but was probably related to the Middle English and Old English finn, the Dutch vin, the Low German finne and the Swedish fena. Because all German nouns are capitalized, Heckflosse is correct but in English, where it's treated as a nickname, heckflosse is common.
The (low) rise and (gradual) fall of the Mercedes-Benz tail-fin
Chrysler in 1957 really did claim their tail-fins were not mere decorations but "stabilizers" designed to move the centre of pressure rearward. Although designed during Detroit’s tail-fin craze during the mid-late 1950s, Mercedes-Benz always claimed the Heckflosse (tail-fins), introduced in 1959, weren’t mere stylistic flourishes but rather Peilstege (parking aids or sight-lines (literally "bearing bars")), the construct being peil-, from peilen (take a bearing; find the direction) + Steg (bar) which marked the extent of the bodywork, this to assist while reversing. It's never been clear if this interpretation existed during the design process or was applied retrospectively in response to criticism after the debut but by 1960, even in the US where fins has assumed absurd proportions, the fad was fast fading. As a cultural artefact, the distinctiveness of the Heckflosse made them a staple for film-makers crafting the verisimilitude of the 1960s high cold war, just as the big 600s from the same era are used still when wealth or evil needs to be conveyed.

On the sedans, the uncharacteristic exuberances were left undisturbed until production ended in 1968 although the line was restricted to a line of lower cost utilitarian models after 1965. The coupé and cabriolet were introduced in 1961 and lasted a decade; truncating the Heckflosse, they achieved an elegance of line Mercedes-Benz has never since matched but then, few have.

By 1965, on the W108 and W109 (1995-1972 and which replaced the more expensive W111 models & all the W112 sedans), the fins, those barely discernible, still existed, the factory noting the contribution to structural rigidity, adding strength without the increase in weight the use of other techniques would have imposed.

Advances in metallurgy and engineering meant achieving the required strength became possible even without additional curvature in the metal and in 1971 the R107 (roadster 1971-1989) and C107 (coupé 1971-1981) debuted with the rear surface an uninterrupted flat plane.

Despite that, a year later, the W116 sedans (1972-1980) were released with the most vestigial of fins. The retention of styling elements between generations is not unusual, the second generation Range Rover reprising the earlier model’s distinctive hood creases, even though no longer a structural necessity. Because there was uncertainty around whether US regulators would outlaw convertibles, no coupé or cabriolet version of the W116 was developed which is why a LWB coupé version of the R107 SL was released (as the C107 SLC) and the R107 lasted an impressive 18 years, not replaced until 1989.
The Heckflosse as rally and race car
To those accustomed to how things are done in the modern WRC (World Rally Championship) or have memories of the marvellous Group B cars of the 1980s (a category which enthralled everybody except the clipboard crew at the FIA (Fédération Internationale de l'Automobile (the International Automobile Federation)) which, being international sport’s dopiest regulatory body, of course outlawed the things) it will seem improbable the Heckflosse would have been a successful rally car but the record was illustrious. It’s best remembered for the 220 SE which won the 1960 Monte Carlo Rally but there were many other successes including the 1961 Algiers-Cape Town Central Africa Rally, an arduous event of some 13,500 kilometres (8400 miles) conducted over several weeks on a route from Cape Town to Algiers (a 190 D (a diesel-engined W121 “pontoon” rather than a Heckflosse) had won in 1959 which proved it was a rally which didn’t rely solely on speed). First run in 1951 and based on an event staged in 1930, in 1956 a Fiat 1100 and a Ford Ranch Wagon V8 (two vehicles most unalike) had tied for first place, the latter driven by Elon Musk's (b 1971) maternal grandfather, chiropractor Joshua Norman Haldeman (1902–1974), who was an interesting character.
The most prestigious African rally was the East African Safari and a Heckflosse 220 SE won in 1961, following victories by 219s the previous two years. The 219 (W105, 1956-1959) was a curious anomaly among the post-war Mercedes-Benz saloons in terms of both nomenclature and engineering. Using a “mix & match” approach which had been part of the transportation business even before things became motorized, the 219 used the 2.2 litre six-cylinder engine familiar in the various 220s (W128 & W180) but mounted it on the shorter “pontoon” platform used by the 4-cylinder 180 & 190 (W120 & W121) variants, the sacrificed length all accounted for by the shorter rear-doors (and thus wheelbase). It was one of the more elaborate “de-frilling” exercises seen around the world, the variations including a lower cost version of an existing model (Citroën ID vs DS or Chevrolet’s Biscayne vs the Bel Air & Impala) or an existing body with a smaller engine substituted (Humber Hawk vs Super Snipe). The 219’s designation was unusual in that it was the only occasion the familiar three numerals featured something other than a “0” as the last digit and it’s notable also because the factory, in a blatant attempt to evade the taxes levied on cars with 2.2 litre engines, slightly reduced the displacement. The FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany) 1949-1990) government must have decided this was “un-German” trickery (dieselgate was decades away) because eventually they informed Daimler-Benz the 219 would be taxed as a 2.2 litre vehicle, This brought production to an end because the effect of the tax increase would have negated the advantage the 219 had enjoyed.
Although not obviously a machine built for the circuits, the Heckflosse did win enjoy success on the tack, a 220 SE in 1961 winning the second Armstrong 500 in Australia, the event which became the annual Bathurst 1000. It was even less obviously a rally car but the 220 SE enjoyed a remarkable record in the Poland Rally, winning four successive titles between 1960-1964 and the car also won the 1962 Liège-Sofia-Liège, the factory taking the title in the same event in 1963 with the new 230 SL (the W113 “Pagoda”, 1963-1971). The Heckflosse also won the Acropolis Rally in two successive years, a 220 SE taking the chequered flag in 1962 and a 300 SE (W112) the following year. The 300 SE was very much a luxury model which used the then still novel engineering of air suspension which provided a smooth ride but added to weight and complexity, neither quality sought by teams using cars in competition although the system did have the advantage of permitting ground clearance easily to be adjusted; to compensate for the added mass, the 300 SE used a variant of the 3.0 litre straight-6 from the 300 SL (W198; 1954-1963) Gullwing and roadster, a powerful, robust unit. However, by 1963 it was obvious the days of the big sedans being effective rally cars was drawing to a close; the greater power of the 300 SE had permitted the Heckflosse quite an Indian summer but the immediate future clearly belonged to lighter, more nimble machines such as the Alfa Romeo Giulia, Mini Cooper, Saab 96 and Volvo 122.
However, whether on the circuits or the rally course, there was in the early 1960s nothing unusual about men winning trophies. What was special came on 4 November 1962 when two Swedish women (driver Ewy Rosqvist (1929–2024) & co-driver Ursula Wirth (1934–2019)), in a 220 SE Heckflosse, won the sixth Argentine Turismo Standard Grand Prix, conducted over five days and a distance of 4,625 km, (2,874 miles) on some of the country’s most gruelling and mountainous roads. Not only did the women win the long-distance event, the dominated it, for the first time, a single vehicle won in succession all six stages of the Grand Prix and in doing so they set a new race record. To rub it in, all other competitors were men.
Working as a veterinary assistant travelling between remote farms, Ewy Rosqvist was brought up on a diet of twisty, often icy roads of dubious quality and it was on those she learned the finer points of rally-style driving, travelling sometimes up to 200 km (125 miles) in a day. With animals to care for, speed was required (in her bag was often some “time-critical” bull semen) and she took to keeping a log-book in which she recorded how long it took to go from one farm to the next; these entries she regarded as her “lap times”. Later, she would recall the “unpaved roads, gravel paths and farm roads” with some gratitude because they honed techniques which proved good enough for her to win several European rally championships; she called her memoir Fahrt durch die Hölle (Driving through Hell (1963)).
Although Daimler-Benz were not unaware of the publicity which would be generated by having a women driving for their competition department, when in 1962 the factory offered her a seat in the Mercedes-Benz works team, genuinely she was appointed on merit and in South America she justified her place. The team had appeared in Argentina with a four-car entry for the Turismo Standard Grand Prix (two 220 SEs (W111) and two 300 SEs (W112)) and the operation was run with the sort of thoroughness which had characterized their Grand Prix campaigns in the 1930s & 1950s and, given the conditions encountered, it was just as well: of the 286 vehicles which started only 43 finished. Immediately the women made an impression by winning the first stage and they repeated the feat on the subsequent five, eventually finishing three hours ahead of the second-placed Volvo and setting a new record average speed of 126.87 km/h (78.84 mph). Undeniably, the women were the most glamorous and photogenic in the field and they captured the country’s imagination, German language newspaper Freie Presse (published in Buenos Aires) reporting: “It was not the Cuban missile crisis, but rather the two blondes from Scandinavia who dominated the headlines in the country’s daily newspapers.”
