The Mercedes 24/100/140 PS was a large luxury car introduced by Daimler of Untertürkheim in 1924. Production continued until 1929 by which time Daimler had merged with Benz & Cie (effective 1926) and the car's name changed to Mercedes-Benz Typ 630.[1] The car was conceptually and structurally similar to the contemporary Mercedes 15/70/100 PS, but the 24/100/140 PS was longer, heavier, more powerful, faster and more expensive.
A still more powerful Mercedes-Benz Modell K sports car version, sometimes known as the Mercedes-Benz 24/110/160 PS, was offered between 1926 and 1929.
A defining feature of the cars was the switchable supercharger (”Kompressor”) fitted to the engine.
Origins
Plans for the car were drawn up by the company's Technical Director, Paul Daimler, son of the company's founder. Following an acrimonious disagreement about new model policy, Daimler left in 1922, transferring to rival manufacturer Horch. It was left to Daimler's successor, Technical Director Ferdinand Porsche, arriving at the plant from Austria in April 1923, to complete the development and handle the launch of the 24/100/140 PS. The strategy for the model's development, which used knowledge gained on the race track from the company's successful racing cars to develop a large, fast, and very expensive road car, appears to have been similar under both men.
