These Twenties Mercedes supermodels with a ‘Okay’ suffix had superchargers, and easily attractive strains. , , and this yr we have fun three very particular automobiles on the MBCCR.
The supercharger was really born earlier than the automobile. In reality, its journey really began with blast furnaces. Then in 1885, Gottlieb Daimler acquired a patent for a supercharged engine. Sure, a yr earlier than the patent for the primary automobile. So Merc was into supercharging from the get-go. The supercharger is a tool that blows extra air right into a combustion chamber so you possibly can burn extra gas. Superchargers turned well-liked within the mid-Twenties when firms like Mercedes, who may deal with all of the precision and tech, took the assistance of those ‘blowers’ to make their engines produce extra energy.
The primary Mercedes supercharged engines, nevertheless, weren’t utilized in automobiles – they have been utilized in World Warfare I plane, round 1917. It began with the Daimler D IVa. Displacing 21.7 litres, the supercharger helped this engine make the identical quantity of energy at sea degree and at excessive altitudes the place the air stress was a lot decrease. This was extraordinary on the time and meant that any fight plane that used this engine, just like the German Albatros, had an enormous benefit over rivals at excessive altitudes. Rivals operating naturally aspirated engines typically misplaced as much as 40 % of their energy at greater altitudes.

It was additionally Daimler who launched the primary supercharged manufacturing automobile in 1923. These have been the 1.6 liter 6/25 hp and the two.6 liter 10/40 hp, each of which have been referred to as Kompressor fashions. Over the subsequent few years, Mercedes would go on to supply a string of very profitable and engaging supercharged fashions, all suffixed with a Okay, and we’ll have fun these automobiles at this yr’s MBCCR.
What makes these automobiles so fascinating is that Kompressors have been among the many most superior automobiles of their age. Utilizing a mix of aero tech and tech from the Grand Prix automobiles of the time, that additionally used each straight-eights and supercharging, the icons of the vary have been the 500K and the larger-engined 540K (lead picture); each of which it is possible for you to to see and listen to at this yr’s rally.
Powered by a 5.0-litre supercharged straight-eight, the 500k was among the many quickest automobiles of its time.
Each went on sale within the mid 30’s, the 540 following the five hundred. The 500K displaces 5,000cc, the 540K 5,400cc. In contrast to automobiles immediately, the supercharger lower in on these automobiles solely whenever you went to full throttle; which made it comparatively easy to meter the gas and air and decide the right spark timing. As soon as the supercharger was engaged, energy was elevated to 160hp, permitting for speeds in extra of 150kph on the 500K. This made it among the many quickest automobiles on the planet on the time.
The 540K was much more highly effective and made 180hp. Ensure that to listen to these straight-eights rev if the engines are began; they sound very totally different with their lengthy crankshafts and lengthy drawn out, clean engine notice. And be sure to examine and distinction them with the extra pulsating sound of engines with a decrease cylinder depend. When you are unlikely to listen to the whine of the supercharger, do maintain an ear open for the howl because the automobile passes by.
540K’s straight-eight engine with the supercharger mounted on the opposite aspect.
What’s attention-grabbing is that these automobiles aren’t nearly engine efficiency, the 500Ks and 540Ks are merely attractive, with large flowing fenders, recessed and pointy Mercedes radiators, raked windscreens, and impartial suspension. Each automobiles even have very attention-grabbing origins; whereas the 540K that belongs to the Pranlal Bhogilal assortment got here from the state of Jawhar (that is not too removed from Mumbai), Hormusji Cama’s 500K is claimed to have come from the Kingdom of Nepal.
In accordance with Mercedes, a complete of 760 500K and 540K fashions of the W 29 collection have been made between 1934 and 1939. Of those, 354 had the 5.0-litre engine and 406 the 5.4-litre engine, the latter from 1936 onwards. Round 60 items of the variants with roadster bodywork have been produced. So these automobiles are fairly uncommon and worthy of being displayed in a museum.
The 1929 630K used a six-cylinder supercharged engine.
The third automobile, Harshvardhan Ruia’s 1929 630K – previously of the state of Tikari – is much more of an eyeopener. This explicit automobile was bought after the merger of Daimler and Benz (in 1926), however what’s fascinating is that earlier Daimlers have been bought underneath 24/100/140 nomenclature – the identify primarily based on the varied horsepower figures based on tax legal guidelines and actual and nominal. horsepower. And whereas the 500K and 540K use eight-cylinder engines, this automobile used a six cylinder. The extra stately 4 door was initially imported by way of Kolkata and showcased the breadth of automobiles from Daimler and Benz that ultimately used supercharged engines.
