The 1906 Mercedes 120HP Rennwagen holds a significant place in automotive history as one of the pioneering racing cars of its time. Here's a breakdown of its key features and historical context:
Engine: It was powered by the first six-cylinder car engine designed by Maybach, featuring an inline-6 configuration. This engine, designated M 14126, had a displacement of 11080 cc (676.1 cubic inches), with a bore of 140 mm (5.51 inches) and a stroke of 120 mm (4.72 inches). It produced 125 horsepower at 1500 rpm, setting it apart as a high-performance machine of its era.
Racing Success: The 1906 Mercedes 120HP Rennwagen achieved notable success on the racetrack, with Otto Salzer winning the 5th Ardennes race in this car on August 13, 1906. However, due to insufficient testing, the car's intended use in the 1906 Grand Prix was abandoned, and it was replaced by four-cylinder engines.
Technical Details: The car featured different versions of the engine, with some equipped with a double plug ignition and others with a make-and-break ignition. These technical variations led to a dispute between Maybach and Emil Jellinek, the individual who ordered the engine, ultimately resulting in Maybach's departure from the company.
Specifications: The car boasted impressive performance figures for its time, with a specific output of 11.28 horsepower per liter and a top speed of around 150 kph (93.2 mph). It had rear-wheel drive (RWD) and was equipped with a 4-speed manual transmission. The chassis was constructed with a steel body over a pressed-steel frame, contributing to its durability and performance on the track.
Dimensions: With a curb weight of 1000 kg (2205 lbs), a wheelbase of 2690 mm (105.9 inches), and overall dimensions of 3720 mm (146.5 inches) in length, 1630 mm (64.2 inches) in width, and 1470 mm (57.9 inches) in height, the car had a commanding presence on the road and the racetrack.
Overall, the 1906 Mercedes 120HP Rennwagen represents a remarkable engineering achievement and a significant milestone in the evolution of racing cars, showcasing the innovative spirit and technical prowess of its era.
