1937 Mercedes-Benz 540 K
Released at the Paris Motor Show in 1936, the 540K became Mercedes-Benz’s flagship model and was built by special order only. It followed the eight cylinder 500K and helped maintain the company’s prestige by being one of the fastest production cars in the world.
At the Paris Motor Show, Mercedes-Benz said the 540K name ”conjures up visions of breath-taking exploits of racing cars and drivers of international fame, but also of superlative comfort and coachwork of exquisite beauty, fine paintwork, brightly polished metal, the finest hardwoods and leather – massive and yet outstandingly attractive bodies – in short: the car for the connoisseur.”
Each car was individually built to the customer’s needs and Mercedes-Benz prepared a range of available bodies. Among these, were the spectacular Spezial Roadsters built Mercedes-Benz’s own Karrosserie Sindelfingen. These flowing two-seaters were one of the most striking prewar designs, distinguished by their prominent hood, sweeping fenders, external exhaust pipes, raked windscreen and extreme length. The are still, arguably, the most beautiful German supercars and have a commanding presence.
Engineer Gustav Rohr was responsible for designing the 540K cruisers and upgraded them while he also worked on the incredible Mercedes-Benz Grand Prix cars. He fitted an enlarged 5.4 litre inline-8 which was good for 180hp and 170 kph. The main highlight of the engine was its gear driven, Rootes-type supercharger (or Kompressor) which would spool up on demand to increase the avilable power from 115bhp to 180bhp when engaged. This setup was a similar to the supercharged S, SS and SSK racecars which were designed by Ferdinand Porsche to help Mercedes-Benz dominate racing in the twenties.
When built, the 540K featured an updated chassis with a longer wheelbase that extended the hood and allowed for a new vee-shaped radiator. Rohr also included better suspension and braking. Like the earlier cars, the suspension was also fully independent.
Factory records show that 419 of these cars were built and featured a wide array of coachwork. Surprisingly, most were built by the factory’s own Karrosserie Sindelfingen which was managed by Wilhelm Haspel. They offered a variety of Cabriolet bodies that were designated ‘A’ through ‘D’. These were joined several coupes designs and the very coveted Special Roadsters.

1937 Mercedes-Benz 540 K Cabriolet C 169312 – sold for €506,000 Launched at the Paris Salon in October 1936, the 540K had an engine that developed 115bhp un-supercharged or 180bhp with the compressor engaged. The gearbox was a four-speeder, but with a direct top gear rather than the overdrive ratio used on the earlier 500K. With the supercharger engaged, the 540K’s blown straight-eight gave it a top speed approaching 110mph (177km/h) matched by servo-assisted hydraulic braking. Its performance potential was such that Mercedes-Benz in the UK retained racing driver Goffredo ‘Freddy’ Zehender as technical adviser and demonstration driver, since the super

1937 Mercedes-Benz 540K Sport Cabriolet A 154084 – sold for $2,145,000
As imposing as ever, this spectacular 540K remains in show-quality condition throughout and is poised to be a star of any concours. Eligible for the finest events worldwide, this beautifully prepared Mercedes-Benz is, without question, one of the most attractive open luxury cars of the era and is an outstanding example of German engineering at its finest. Possessing a rarely matched combination of quality, overall performance and comfort, the 540K walks the fine line between sports and luxury cars and sets the standard for the competition. In the late 1930s, there were only a handful of vehicles that could claim the same stature as an open, two-door supercharged Mercedes-Benz.
The extraordinary attention to detail found in every facet of this car reflects both the passion of its original creator as well as the precise, accurate work of the restorers who have tended to this magnificent motorcar. From the pristine engine bay with its gleaming chrome pipes and engine-turned finishes, to the spectacular interior trim with its highly-polished woodwork, mother of pearl instrument panel and bakelite fittings, to the even glow of its imposing Bosch headlamps, this Mercedes-Benz is the automotive embodiment of classical elegance.
No great collection can do without an attractive, open 540K. The late production Sport Cabriolet is considered to be the most beautifully proportioned of the line and is certainly the most desirable of the entire Sindelfingen cabriolet series. Their long rear coachwork with rear-mounted spares, deeply backset radiator and elegantly sweeping lines put them on a visual par with the Special Roadster. The cresting high-door design and voluptuous clamshell fenders place this Roadster amongst the most desirable of all Mercedes-Benz motorcars.
The Sport Cabriolet A presented here is an example of great distinction, a proud representative of the marque, tour proven and a serious concours contender. Truly a Mercedes-Benz that sets the bar, it needs only a new caretaker to continue in its dignified manner and unsurpassed style.
