It was a distinction to be able to drive a car: in the 1920s and 1930s, the cars from Mercedes-Benz and the brand Mercedes eclipsed all the and refined cars that had until then. They a new era in automotive engineering. Captains of and politicians, artists and sports men and – the people driving supercharged cars in those days for an image of savoir vivre and for the most advanced engineering and the refined design. In short, for the cars in the world.

Daimler-Motoren-Gesellschaft used the valuable experience with the supercharging of aircraft for boosting the power of vehicle for the first time after War I – and a new performance category was The first supercharged Mercedes were displayed at the Berlin Show in 1921 and caused a stir among automotive Racing cars were equipped with superchargers, and in 1922, Max Sailer won the production car of the Targa Florio at the wheel of a 28/95 hp Mercedes.

The first were followed, for instance, by the Mercedes (1921 — later renamed model the 24/100/140 hp Mercedes (1924 1929, later renamed and the 630 K (1926 — They dwarfed the competition their sheer size as exemplified by the legendary supercharged

sports cars from the S with six-cylinder engines, models S (Sport), SS (Super – SSK (Super – Sport – Kurz) and (Super – Sport – Kurz – “Kurz” standing for short and for light. The S models came the market from 1927, one after the merger of DMG and Benz into Daimler-Benz AG, and they the benchmark in the category of super cars. They dominated the sport scene until – creating a legend in acoustic as well. This was because the enormous power development was by the distinctive sound of the supercharger, a screeching of the air compressed in the chargers. compared the howling with a of the “Trumpets of Jericho”. The more inclined felt reminded of the battle cry” or suspected a goddess of vengeance” under the engine hood. The character of the sports cars with engines was best summarized by the “Thunder and lightning” with the British classic-car magazine and Sportscar once described the of a Mercedes-Benz SSK in the classic Shelsley-Walsh race.

Expression of performance, and maximum exclusiveness

From the supercharger was also used, in damped form, in the brand’s eight-cylinder cars, the Mercedes-Benz the 500 K and 540 K. These from the previous cars in character in that they had designed for fast and comfortable rather than racing. At the time, these and other were expressions of performance, and maximum exclusiveness. Each car was manufactured by hand, often to the wishes and ideas of customers.

The to perfection which prevailed in the and manufacture of the supercharged Mercedes-Benz was the foundation for the fascination these have been exuding to very day. Whether in the leading Concours d’Elegance, in racing events or in reliability – a supercharged car from Mercedes or moves into the limelight it appears.

Supercharged models the 1920s and 1930s all have one in common: they represent the in automotive engineering in their era. To drive them, to the shriek of the mechanical charger, to the power of its engine, to enjoy the of the refined ambience or to compete in at the wheel of an S model – that was the crowning glory of motoring.

The small production volume the supercharged cars from into exclusive collectors’ for just a few privileged enthusiasts. cars are therefore hard-fought-for at classic-car auctions. In the auctioneers’ they are usually depicted the recommended prices which are customary. Someone who really such a car does not have to it valued.

The supercharged cars exemplify the enormous range in the of Mercedes-Benz in those days, everyday models at the one end, sound and technically perfect through to the supercharged cars at the end, which met the highest on outstanding engine power and the refined equipment. This of Mercedes-Benz, namely to meet the needs perfectly in every is today as strong as ever, as by products ranging from the through to the AMG versions of the luxury-class

Incidentally, present-day supercharged models share nothing but the with the first and second of supercharged cars from the years. In today’s models, the boosts output and torque and permanently while at the same ensuring excellent fuel it contributes to a reduction in weight in combination with other to improved emission control as

The supercharger conquers the automobile

brothers Francis and Philander filed a patent application for blower in1860, they had no that their charger once become the stuff of legends. The two manufacturers from in the American Middle West had only intended to boost the of the water turbine in their company.

Their rotary-piston is the prototype of all Roots blowers as are still being used in production today. On principle, the blower works like a pump. However, instead of two gear wheels, two counter-rotating with octagonal cross-sections are to deliver the gases. The rollers with small clearances in a whose interior basically of two hemispherical parts which are at a certain distance. The gases are by the delivery pressure. The supercharger is by the crankshaft – in the Mercedes-Benz 500 K, for it rotates at four times the speed.

When such a blower is installed as a pressure ahead of the carburetor, it presses air into the carburetor where it is with fuel. The advantage a carburetor without upstream is that the Roots blower the cylinder charge through – and a higher charge produces power.

A suction-type supercharger behind the carburetor operates to the same principle in that it is a wet charger which compresses the mixture. The effect is the same as in the of the pressure carburetor. Its advantages to the fore in racing where the supercharger copes with loads thanks to the better cooling of the fuel/air mixture.

The cars of Mercedes and Mercedes-Benz featured pressure-type superchargers were easier to service. In the 500 K, for instance, they an excess pressure of 0.3 bar and boosted from 100 naturally-aspirated hp (74 kW) to 160 supercharged hp kW).

From testing to production

Shortly before the end of World Paul Daimler, son of automobile Gottlieb Daimler and Chief at DMG, equipped the Knight engine of a 16/50 hp Mercedes a Roots blower. He drew on the gained with superchargers in and submarine engine production World War I, where the air compressor had been used to for power losses at high However, the sleeve-valve engine to be unsuitable for combination with a

A large number of tests then made with the large six-cylinder 28/95 hp engine with a displacement of which generated 140 hp (103 kW) a supercharger. The results of these were promising. In 1922 a with the supercharged 28/95 hp was entered in racing for the first in the Targa Florio, and Max Sailer the car to victory in the category of production upward of 4.5 liters and thus to place in the overall rankings.

before that, Paul had experimented with the small four-cylinder 10/30 hp Mercedes caused quite a stir at the Berlin Motor Show it was displayed as a supercharged 10/35 hp alongside the 1.6-liter four-cylinder Another two years would before production maturity was At any rate, in the cars renamed and 6/25/40 hp in 1924, the supercharger output by a good 50 percent.

the technology was extremely complex at the and therefore came at a high The first supercharged Mercedes were highly expensive in their day and age, and only numbers were sold. And yet laid the foundations for ongoing

Matured high-performance cars

Paul Daimler left the founded by his father in 1922, Porsche took over as Engineer and continued Daimler’s He, too, swore by supercharger knowing that the sophisticated system was primarily suitable for and luxury cars. Consequently, first designs for DMG were cars – the 15/70/100 hp Mercedes and the Mercedes (the latter available in six different bodywork for instance). The engines featured crankcases as well as cylinder and cylinder heads made of cast iron.

As was customary at the the first figure indicated the tax rating which depended on the second the engine output in aspirated operation and the third the with the supercharger engaged. the two Porsche designs with and 6.3-liter six-cylinder engines introduced at the Berlin Motor they ranked among the powerful road-going cars of day and age, courtesy of their blowers.

They were by a car from their own ranks, the Mercedes-Benz K built from its two predecessors – renamed Mercedes-Benz 400 and 630 – in the range for the time being the merger of DMG and Benz Cie. in In contrast to the supercharged eight-cylinder cars launched at a later from 1934, however, the “K” did not for ‘supercharger’ (Kompressor in German) but for ‘short’ (kurz in German) to to the car’s 35 centimeter shorter Other versions available the 620 K and 630 K, both 24/110/160 hp; the 630 K had a top speed of 145 km/h and was thus the fastest car of its time. The 680 K was made with 26/120/180 hp engine and as a car only with 26/145/270 hp Incidentally, the special feature of the was the arrangement of three silver-colored pipes on the outside of the engine on the right-hand side and serving as a hallmark of the supercharged Mercedes-Benz in addition to their acoustic namely the supercharger’s distinctive

Despite all these superlatives, the Mercedes models of the early were merely tentative for what Daimler-Benz would from 1927: the Mercedes-Benz S, SS, SSK and

Sheer power

First first victory. The Mercedes-Benz S, had been developed in Untertürkheim February 1927, made its public appearance in the opening on the Nürburgring on June 19, 1927 – and its debut with a superior victory. It thus underpinned its to replacing the 630 K as the fastest car in its day and age.

With model Mercedes-Benz S, SS, SSK and SSKL, the supercharged built from 1927 down in history. There are any other passenger car series in history which have as many superlatives as the S models Stuttgart. No other contemporary vehicle was capable of such speeds while at the same being as robust, reliable and And no other car exudes as much fascination as the large supercharged models from Mercedes-Benz – after they went out of With these cars, Porsche set himself an impressive monument.

Based on the 630 K and the developed version, with a six-cylinder, displacement enlarged to 6.8 and lowered chassis, the S surpassed its in every respect. Without the engaged, an early version of its with overhead valves as much as 120 hp (88 kW) to the rear wheels. And the accelerator was pressed down the full-throttle point, the Roots driven by bevel gears was causing the multi-plate clutch to a mighty 180 hp (132 kW).

Mercedes-Benz built 146 units of intriguing S sports cars the designation 26/120/180 hp – as two-seater cars, open tourers and convertibles. However, as early as the 27/140/200 hp SS, internally known as was launched. With a compression raised from 1:4.7 to the engine, equally fitted double (magneto and battery) generated 20 hp (15 kW) more the first version. Between and 1930, 111 buyers raised the Reichsmark charged for an SS model.

the single S stood for ‘Sport’, the SS denoted ‘Super – Sport’. with the S model, which was blessed with a host of the SS caused the degree of fascination to A displacement enlarged to 7.1 liters, pistons, a larger valve and output ratings of 200, 225 and 250 hp 165 and 184 kW) fully justified the epithet

This was the absolute dream car in its day and However, contemporary sports car would have quoted an more attractive proposition, the SSK with a chassis that was 45 shorter than that of the SS. the supercharger engaged, the 7.1-liter generated up to 250 hp (184 kW).

power-pack was surpassed only by the SSKL (W 06 RS) – a thoroughbred car with a mighty 300 hp (221 Thanks to numerous weight-shedding the car was some 200 kilograms lighter the SSK which weighed in at 1.7 tons.

Contemporaries may have seen car as an infernal machine. Its drivers, enjoyed a whole string of in the Mille Miglia (Rudolf 1931) and many other races in the 1920s and 1930s.

In his book The Mighty Mercedes in 1971, technical author Frostick describes the appearance of the Mercedes-Benz models with precision. This applies to the cars from the S series as as to the other models which the supercharger legend into the Mechanical engineering at its best, bodybuilding and hitherto unknown of luxury – these were the of the Mercedes-Benz 380 (W 22, 1933 1934), the 500 K (W 29, — 1936) and the 540 K and W 24, 1936 — The Grand Mercedes, model was optionally available with a and hardly a customer failed to it. All of these cars represented the in German motor manufacturing World War II.

Cars refined grandeur

While the S, SS, SSK and had impressed people with aggressive appearance and sheer the mighty luxury cars people with refined The supercharged new-generation cars by Chief Engineer Hans were less suitable for achievements – instead, their lay in extremely comfortable and relaxed at high average speeds.

The 380 was in February 1933. It was available different engine versions – of these with supercharging. The 380 was the to feature a four-speed transmission the top gear designed as overdrive. different bodies were ex factory: sedan, tourer, roadster and three different This was also the first that independent wheel all round ensured excellent and ride characteristics in a car of this

The 380 was replaced by the more powerful in 1934. In engine design, set particularly great store by smooth running characteristics and power which nonetheless gently – and the engine proved to be majestic indeed. The eight-cylinder engine of the 500 K – and of the 540 K at a stage – was over one meter and consisted of a special sound-absorbing cast iron. The gray iron cylinder head with parallel overhead actuated via rocker arms and rods from the lateral demonstrated the very best in However, this high of mechanical refinement came at a in the form of weight: the complete engine of a 500 K weighed than 600 kilograms.

Both the and the 540 K available from were offered with two lengths. The short chassis a wheelbase of 2.98 meters as the backbone for the sporty roadster and versions as well as for the short A version of the 540 K.

The Sindelfingen sets standards

The long with a wheelbase of 3.29 was available in combination with all versions. In their design the bodybuilders in Sindelfingen pulled out all stops. Their creations of unsurpassed elegance, the highest accuracy, impressive durability and workmanship. In addition, they even the most eccentric wishes with respect to and design. Snake-skin seat mother-of-pearl inlays in the dashboard, sweeping fenders – everything was Even the standard range more than ten bodywork – from the streamlined coupe via and open tourer to convertibles A, B and C and the and special roadsters – left anything to be desired. Over and this, the 540 K was also as motorway courier with bodywork.

The demanding clientele appreciated generous choice and the outstanding of the plant’s own bodybuilders. Contrary to was customary at the time, namely to the chassis from a manufacturer and a body of one’s own choice by an independent bodybuilder, the majority of and 540 K buyers ordered from the Daimler-Benz plant in

At 160 hp (118 kW) with the supercharger the output of the 500 K was already than lavish by contemporary but the 540 K built between and June 1943 capped it all off displacement enlarged by 0.4 liters, with the supercharged engaged by 20 hp (15 kW) and, most importantly, a major boost in torque.

The Mercedes

The 770 Grand Mercedes was the car in the company’s model line-up at the It would hardly have possible to travel in a more and more luxurious style. The W 07 series (1930 1938) was available with or supercharger. With supercharger, the engine generated 200 hp (147 kW) a displacement of 7.7 liters. In this the supercharger was not meant to give the car a performance but served as a highly acceleration aid – the car did after all weigh 2.7 tons, depending on equipment. The version (W 150) with eight-cylinder engine was launched the market in 1938 and continued to be until 1943. The engine 155 hp (114 kW) from a displacement of 7.7 liters – and 230 hp (169 kW) with the engaged.

Race victories the supercharger

Targa Florio the very first time the 28/95 hp Mercedes with Max at the wheel was entered in a major it won the category of production touring upwards of 4.5-liter displacement. victory marked the start of a string of successes of supercharged and Mercedes-Benz racing cars.

In the the nimble 1.5- and two-liter cars with superchargers success after success for And when the first outing of the S in the opening race on the Nürburgring in ended with a one-two this was the beginning of a period of uninterrupted dominance by the supercharged from Untertürkheim – right to the outbreak of World War II.

The supercharged six-cylinder engines of the S, SS, SSK and SSKL topped the winners’ with dogged regularity. in the German Grand Prix in 1928 and 1931, first in the Argentinean Grand Prix in and 1931 and the only overall of a German driver in the legendary Miglia to date, scored in by Rudolf Caracciola at the wheel of an

SSKL – all these were of the supercharger’s superiority.


When Mercedes-Benz entered the for the new 750-kilogram formula in the Eifel in 1934, the supercharged eight-cylinder car launched the Silver Arrow first start, first – thereby setting the standard for to come. The Mercedes-Benz W 25, W 154 and W 165 dominated the Prix races – with the of those in 1936 – at will. works drivers clinched the Champion’s titles in 1935, 1938 and 1939.

Not only the were impressive, however. The supercharger sound of the W 25 and engines with up to 700 hp (515 of the small 1.5-liter V8 with 254 hp kW) in the W 165, and the infernal howling of the W 154 V12 with up to 483 hp (355 kW) from 1937 … the of all other racing cars until then.

Celebrities and supercharged cars

Birds of a flock together – relating to than 120 years of automotive this saying illustrates the that international celebrities always had a soft spot for of the Mercedes and Mercedes-Benz brands – at the wheel of cars with the star. With the launch of the era, this predilection a passion: aristocrats, top managers, and actors, singers, politicians and of industry did not want to be without Mercedes cars.

Wilhelm for instance, owner of a Darmstadt-based company, even competed in races with his SSK. His Ernes Merck equally up at the start of races in her Mercedes-Benz S, them the Klausen Pass race in 1927.

Alfred owner of a brewery in Stuttgart, had his S into an SS – it is not known whether was done for racing or not. By and only a minority of the celebrities supercharged cars with the aim of sporting laurels. First and they wanted their for image-enhancing or representative purposes.

his period of office as Foreign former Chancellor Gustav had himself chauffeured in a 24/100/140 hp Star tenor Richard posed highly adorably to his 15/70/100 hp Mercedes in photos for the yellow press. British Lilian Harvey (who among others, in the German “Die Drei von der Tankstelle”) on her Mercedes-Benz SS. Crime fiction Sir Arthur Conan Doyle part of his Sherlock Holmes in an SSK.

The list of celebrities the Mercedes-Benz 500 K and 540 K be continued ad infinitum: Marika and Gustav Gründgens drove the as did singers Jan Kiepura and James However, few contemporaries were enough to be able to combine profession with their as much as Rudolf Caracciola, for The Number One among the Daimler-Benz Prix works drivers had the latest supercharged model at his from S via SS and SSK through to the 540 K coupe – all of them made to him as company cars.
