product description

A masterpiece of architecture model: M-120 CMC Mercedes-Benz 300 SLR Engine, with showcase

Technical data of the CMC-model:
  1. Model: Assembled, handmade precision model
  2. Manufacuter: CMC GmbH, Classic Model Cars, Germany
  3. Scale: 1:18
  4. Art.-No.: M-120
Description of the original vehicle: The basic design of this engine, apart from displacement, is virtually akin to what we see in the engine of the Grand Prix car W196. By comparison, the displacement of the 300 SLR engine is 486 ccm larger than that of its counterpart, while its stroke/bore is increased to 78 x 78 mm. Moreover, the top speed is attained at 7,500 rpm in this engine, as against 8,500 rpm in the W196 engine.
The 300 SLR was so designed that even when the engine was running on low speed, a fast revving-up capacity was available. This feature mattered a lot in sports car races, where good acceleration provided a very positive advantage. In the building of the 300 SLR engine, a cylinder block made of aluminium alloy was adopted for the first time. Likewise, its cylinder liner was made of chromed aluminium instead of steel. Both represented cutting-edge engineering of their time.
The drive line arrangement of the engine was also innovative. Power transfer was virtually initiated through a pinion gear positioned between the two 4-cylinder blocks that were covered with an 8-cylinder crankcase. Inside the casing was an elaborate Hirth crankshaft propelled by the cylindrical rods that were fitted with roller bearings.
Despite its high compression ratio, the SLR engine was able to run on conventional fuel without any loss of performance, which gave the car an edge in long-distance races on public roads. A good example of strategic foresight that enabled the SLR to stop for refueling anywhere along the way.

Technical data of the original vehicle:
  1. 8-cylinder in-line engine (installed in a 33° inclination to the right side)
  2. Direct fuel injection (positively controlled valves)
  3. Desmodromic valve control
  4. Maximum output: 310 hp at 7,500 rpm
  5. Displacement: 2,982 ccm
