History of Mercedes-Benz

Headquartered in Stuttgart, Baden-Wurttemberg, Germany, Mercedes-Benz is one of the most prestigious luxury brands in the world. It is one of the five business units operated by Daimler AG including Mercedes-Benz Cars, Mercedes-Benz Vans, Daimler Trucks, Daimler Buses, and Daimler Financial Services. Daimler AG, a German automotive corporation is one of the largest manufacturers of commercial vehicles and behind the highly successful Mercedes-Benz brand today. The company has a proud history of excellence across its commercial and private vehicle production.

Daimler-Benz AG now known as Mercedes-Benz was founded in 1926 by automobile pioneers Gottlieb Daimler and Carl Benz. Daimler develops an internal combustion engine, known today as ‘Grandfather Clock’, patented the first motorcycle, and built his automobile, while Benz built the first gasoline-powered automobile. Daimler designed and developed his products with the help of Wilhelm Maybach, a German engine designer, and industrialist. He has several automotive technology breakthroughs to his name and is known as the ‘King of Designers’

Since its inception, Mercedes-Benz has carried forward the legacy of its pioneering founders, continually working at the forefront of innovation across performance, styling, and safety. The renowned brand has lived up to its mission statement ‘Das Beste oder Nichts’ meaning ‘the best or nothing’. The company is consistently delivering groundbreaking innovation, superior automotive design, and diesel engines.

Today, Mercedes-Benz has offices in 93 locations around the globe, which continues to grow. However, it all started from humble beginnings like various other successful businesses that have stood the test of time.

How It All Began

1834: Gottlieb Daimler is born on 17 March in Schorndorf, Germany. He undergoes gunsmith training and attends the Stuttgart Polytechnic School. After completing various technical activities, he goes on to work as a draftsman. He is appointed workshop inspector in a machine tool factory, where he meets Wilhelm Maybach and enters the world of gas engine manufacturing.

1844: Carl Benz is born on 25 November in Karlsruhe, Germany as the son of an engine driver. His father died when he was just two years old and faced financial crises. Despite that, his mother sends him to grammar school and then mechanical engineering school. The young engineer progresses quickly from a locksmith to a designer, and workshop foreman.

1846: Wilhelm Maybach is born on 9 February in Heilbronn as the son of a master joiner. Orphaned at ten years of age, he is adopted in Reutlinger Bruderhaus. During his school time and working in the machine shop, Wilhelm meets Gottlieb Daimler. Their close relationship endures throughout their lives.

1871: Benz joins hands with August Ritter to found his first company, ‘Carl Benz and August Ritter, Engineering Workshop’ in Mannheim. However, the partnership does not work out and they parted ways. He continues his work on a gas-powered two-stroke engine and in the year 1897, he gets the engine running successfully. Carl starts a new company ‘Gasmotorenfabrik Mannheim’ (Mannheim Gas Engine Factory) in 1882.

1872: Gottlieb Daimler becomes Technical Director of ‘Deutz Gasmotorenfabrik’, a gas engine manufacturer where he becomes familiar with four-stroke technology. He is followed to the company by Wilhelm Maybach. He works at Deutz for ten years before leaving to set up a workshop to focus on designing four-stroke engines. Wilhelm goes with him.

1883: Benz founds the company ‘Benz & Cie. Rheinische Gasmotoren-Fabrik Mannheim’ (Benz & Co. Rhine Gas Engine Factory Mannheim) with partners Friedrich Wilhelm Esslinger and Max Rose. The company launches two-stroke ‘System Benz’ engine.

1885: Daimler and Maybach develop a single cylinder engine Daimler Reitwagen (Riding Car).

1886: Benz Motorwagen is introduced to the world. Powered by an internal combustion engine, it is the world’s first automobile.

1890: Daimler founds ‘Daimler-Motoren-Gesellschaft’ (DMG) with business partners Max Duttenhofer and Wilhelm Lorenz. Daimler becomes the Technical Board member and later the Inspector General of the Supervisory Board while Maybach becomes Technical Director.

1894: Carl Benz introduces the Velocipede, known as the Velo. It was the breakthrough that saw Benz & Cie become the second-largest engine manufacturer in Germany.

1896: The world’s first truck for the British Motor Syndicate, Ltd. is built by Daimler-Motoren-Gesellschaft. It is fitted with a 2-cylinder Phoenix engine delivering 4 horsepower and a cargo capacity of 1500 kg.

1901: The first Mercedes is released by DMG. However, Daimler does not witness it due to his premature death. Wilhelm Maybach and Emil Jellinek designed this pioneering 35 hp vehicle. Also, it is the first vehicle featuring the Honeycomb Radiator.

1909: The DMG Board registers two logos as trademarks of the Mercedes brand: a three-pointed star logo and a four-pointed star logo. An engineering genius, Prosper L’Orange, employee of Benz & Cie. had a passion for the diesel engine. He devotes all his skills and energy to create fast running and compact diesel engines. He invents the prechamber injection process and patents the prechamber diesel engine.

1910: Prosper L’Orange achieves three breakthroughs, the funnel prechamber, needle injector nozzle, and the adjustable fuel-injection pump. These advances form the basis for the first diesel engines for use in Benz & Cie motor vehicles.

1923: Benz builds the world’s first diesel-powered truck, 5K3. The truck is equipped with a four-cylinder, 8.8-liter-displacement prechamber delivering 45 to 50 horse power at 1,000 rpm.

1926: DMG and Benz & Cie merge to form Daimler-Benz AG. Carl Benz joins the supervisory board. The prechamber principle developed at Benz & Cie. was the basis for the production of truck diesel engines by the new Daimler-Benz Corporation. The company also began designing a six-cylinder diesel engine for trucks. This was to have higher power output and a higher engine speed, the 1300 revolutions.

1927: The company got a breakthrough with their six-cylinder OM 5 engine. The engine has an output of 55 kW (75 hp) out of a displacement of 8.6 liters. The OM prefix means Olmotor or oil engine.

1929: Carl Benz and Wilhelm Maybach die.

1932: Diesel engines were offered along with petrol engines. The breakthrough for diesel came with the engine in Mercedes-Benz Lo 2000. This was the first truck to feature a diesel engine as standard. The OM 59 six-cylinder engine has an output of 40 kW (55 hp) displacing 3.8 liters of oil.

1936: The Company unveils Mercedes-Benz 260 D at the Berlin Motor Show, the first diesel car. With the four-cylinder engine delivering 45 hp at 3,200 rpm and equipped with a Bosch injection pump, it was an absolute sensation.

1949: 300 series become a legend among diesel engines. The OM 312 six-cylinder diesel engine is developed offering an output of 66 kW (90 hp) with 4.6 .0 displacement.

1954: Mercedes-Benz launched its first turbocharged engine, the OM 312 A. It had an output of 85 kW (115 hp). However, the turbo engine did not achieve popularity. The company further developed OM 321, with a 95 mm bore giving it a displacement of 5.1 liters and an output of 81 kW (110 hp).

1956: OM 321 AM was developed (mild turbocharger), the next generation of turbo engines with 93 kW (126 hp) later 97 kW (132 hp).

1964: Four- and six-cylinder engines OM 314 and OM 352/OM 352 A converted to direct injections. The output increased to 124 kW (168 hp).

1970: A new series of heavy-duty truck diesel engines came out. The 400 series Mercedes-Benz diesel engines made the debut with the new LP 1632 as a V10 engine with a displacement of 16 liters and output of 235 kW (320 hp) at 2500 rpm. The OM 403 with diesel direct injection was introduced.

1980s: The 300 series engines were comprehensively revised. The displacement of four-and-six-cylinder rose to 3.97 and 5.97 liters respectively and output to 147 kW (200 hp) and later to 177 kW (240 hp). The OM 422 A V8 diesel was developed with an output of 243 kW (330 hp) and 14.6 L displacement. The OM 422 LA engine was the first diesel engine to have an intercooler.

1996: 300 series diesel engines came to an end and the Euro III emissions engines production started. The 900 and 500 series diesel truck engines made the debut. With this and the 400 series, Mercedes-Benz covered the entire commercial vehicle spectrum with different ultramodern diesel power units.

2007: BlueTec diesel technology was used in the engines to ensure that the stringent limits of forthcoming emission norms are safely undercut and to achieve clear advantages in terms of fuel economy. SCR (Selective Catalytic Reduction) technology was also used to reduce by up to 80% and lower fuel consumption significantly.

2010: The continued improvement in the technology guaranteed the success of BlueTec and bagged the company the Green Commercial of the Year award by Fleet Transport Magazine. The engine satisfies the EEV (Enhanced Environmentally Friendly Vehicle) standards.
